OISY Wallet was incubated at DFINITY Foundation to simplify DeFi navigation. Initially built for ICP, it quickly evolved to unify primitives across all DeFi chains.

Today, OISY is the world’s first fully on-chain digital asset wallet, consolidating chains, identities, and primitives into a single immutable DeFi terminal.

Powered by ICP’s Chain Fusion technology, OISY delivers security, transparency, and scalability by default.

Internet Identity provides a secure, privacy-focused, and user-friendly authentication solution for the Internet Computer ecosystem. It allows users to securely and anonymously access decentralized applications (dapps) on the platform. Here are the key features of Internet Identity:

1. Passwordless Authentication: Instead of traditional usernames and passwords, Internet Identity uses passkeys, which are cryptographic public/private key pairs. Users can authenticate using biometric methods like fingerprint sensors (TouchID) or facial recognition (FaceID), or hardware security modules like YubiKeys or Ledger wallets.

2. Privacy-Enhancing: Internet Identity creates a unique pseudonym for each dapp a user authenticates with, preventing tracking across different applications and enhancing user privacy.

3. Decentralized and Secure: It operates entirely on the Internet Computer blockchain, allowing users to verify the code it runs. This decentralized approach enhances security and transparency.

4. User-Friendly: Users can create "identity anchors" and assign multiple devices to them, making it convenient to access dapps across different devices without managing complex cryptographic keys directly.

5. No Personal Information Required: Unlike traditional authentication methods, Internet Identity does not collect or store any personal identifying information from users.

6. WebAuthn Integration: Internet Identity is built on the WebAuthn API, which is supported by modern web browsers and operating systems, ensuring broad compatibility.

Preface

If sending a token directly from OISY fails—due to a temporary bug, a third-party dependency, or a token-specific issue—you can still move your funds by connecting OISY to a supported DeFi dApp. Many apps, including Uniswap, allow users to send tokens directly through their interface.

This flow provides a reliable fallback. The example below uses Uniswap, but the same steps apply to other dApps that support WalletConnect.

Send a token using Uniswap

In general, sending a token from your wallet via an web application requires the following steps

1. Open OISY and the application

2. Connect OISY to the application

3. Initiate the send in the application by selecting the token, the amount and the destination.

4. Confirm the send in OISY. This step is important can can often be overlooked, resulting in thinking the send failed.

1. Open OISY and Uniswap

To initially connect and then confirm the send, you manually need to switch to OISY. So it's recommended to have both OISY and Uniswap open in 2 individual browser tabs. The Uniswap URL is: https://app.uniswap.org/

2. Connect OISY to Uniswap

OISY supports a standard method called WalletConnect to connect to DeFi applications. This part shows you step by step how to connect OISY to Uniswap via WalletConnect.

Important: Do not log in to Uniswap 'directly'. Only connect your OISY wallet through the flow described below.

Step 1 - Click "Connect" on top right of the Uniswap homepage

Step 2 - Click "Other Wallets" and then "WalletConnect"

Step 3 - Click "Copy link" on the appearing WalletConnect modal window If you don't see this QR code modal, press a blue QR code button on the appearing modal.

Step 4 - Paste the code in OISY

• Switch to the OISY tab

• click the WalletConnect Button on the upper right part

• Paste the copied link into the field

• and click Connect

Step 5 - And Confirm

All actions that WalletConnect wants to do with your OISY wallet must be confirmed by you. This keeps all your assets safe, and allows you to review all transactions before they take place.

Now you should see that the WalletConnect button in OISY changed into a "Disconnect" button, allowing you to close the connection anytime you want.

You can now switch back to Uniswap. There you should also see your OISY principal on top right instead of the Connect button.

3. Initiate the Send

Step 1 - Click on "Send"

Step 2 - Click on the Token to select the token you want to send.

Step 3 - Enter amount, destination, and hit send.

Step 4 - Confirm the transaction in Uniswap

4. Confirm the Send in OISY

OISY does not allow an application to access your assets unchecked, so have to give consent to each individual transaction that attempts to withdraw assets from your wallet.

To do so, switch to the OISY tab where you should see a confirmation modal open, with the details of the transaction you just initiated.

Approve this modal, and the transaction will be executed.

Uniswap then shows you a notification that the transaction has been executed (takes a few seconds)

And you can then see the transaction appear in OISY (also after a few seconds)

Who controls the private key for the native assets?

The private keys are controlled by the Network Nervous System (NNS), a decentralized autonomous organization (DAO) on the Internet Computer. These keys are secured using threshold cryptography, meaning they are collectively managed by the network and inaccessible to any individual or entity, including Oisy.

Learn more: NNS Overview

What chains is OISY Wallet currently compatible with?

Bitcoin, Ethereum, Solana, ICP, Binance Smart Chain, Base, Polygon and many more to come

Can OISY access the private keys of the native assets?

No, Oisy cannot access the private keys. The private keys are held as decentralized threshold keys on the internet computer. Transactions can be signed only by a user authorized by the NNS-controlled Internet Identity via the NNS-controlled Chain Fusion Signer canister.

Read more: What is the Chain Fusion Signer

How are transactions signed for these native assets?

Transactions are signed by a canister smart contract on the Internet Computer, called the Chain Fusion Signer. This ensures secure and decentralized transaction handling without exposing the private keys.

Read more: How Transactions Work

Is the address created specifically for me as an end-user?

Yes, the address is created specifically for you during the setup of your Oisy wallet. The Chain Fusion Signer canister generates this unique address tied to your account.

Reference: Canister Key Management

How does this wallet differ from Trust Wallet or other multichain wallets?

Unlike Trust Wallet and similar wallets, where you own and manage the private keys directly, the Oisy wallet relies on network custody via the Internet Computer’s NNS. This ensures decentralized control and removes the risk of private key exposure, while still providing you full control over your assets through the canister system.

Learn more: T-Signatures and Custody

Do I really have ownership over this wallet?

Yes, you have functional ownership. While the private keys are held securely by the network, your wallet is tied to your identity, and only you can authorize actions through the decentralized infrastructure. This combines ease of use with decentralized security.

Whats the difference between OISY Wallet and Internet Identity

OISY Wallet and Internet Identity serve distinct roles in the ICP ecosystem. Internet Identity is an authentication tool that creates unique wallets for each app, ensuring security but fragmenting assets. OISY Wallet unifies asset management with one wallet across apps, eliminating fragmentation. It offers features like in-wallet swaps, multi-chain support (e.g., Solana tokens like $SOL), and integrations with dApps like KongSwap. While Internet Identity focuses on secure logins, OISY combines security with advanced tools for streamlined, comprehensive DeFi management. Please see ‘How is my principal handled using OISY’ for slightly more context

How is my principal handled using OISY?

When you connect your OISY wallet to any dApp, it uses the same principal ID, which means you access the same funds across all dApps.

However, when you log in to different dApps using the same Internet Identity, each dApp assigns a unique principal ID. So even though you use the same login identity, each dApp, including OISY, recognizes you differently and assigns a separate principal.

What do I do if I have an issue or a problem?

To ensure you are communicating directly with a team member, please email Support@oisy.com or open a support ticket in our Discord. We will soon introduce a support widget on our website, but currently, these are the only verified methods to reach our team.

Do you have a mobile app or Wallet browser?

We do not have these currently, however the wallet is optimised for mobile and will not interfere with prioritized browser extension modals.

How do I partner with OISY?

To discuss a partnership with OISY, please join our Discord, open a support ticket, and select the appropriate context for your inquiry. This is the required step to initiate the partnership process.

Do you have a tester programme?

Yes, we have a tester program where we engage testers to refine features before releases. To join, keep an eye on our Discord and social media channels for announcements about new tester recruitment.

I’m not seeing the complete history of the tokens in my wallet

If certain tokens are missing from your history, it might be because their Ledger and Index Canisters (IC) need to be added. Informing the project to add these canisters can help us ensure you receive the seamless UX you expect from us.

Why is the price/value not showing for a token in the wallet?

Different wallets use different oracles for sourcing price data. We currently rely on CoinGecko, and because some tokens are not listed there or may fluctuate, their prices may not appear either because they are not available or because of volatility

Why is the token logo not showing for a token in the wallet?

Token logos in OISY Wallet are displayed based on the metadata provided by the token’s canister. If the logo is included directly in the metadata, it will appear in your wallet as expected.

However, if the logo is linked via an external URL, OISY won’t display it. This is an intentional choice to protect your privacy and avoid exposing users to third-party resources that could be tracked or changed.

If you’re a project team and want your logo to appear, please ensure it’s embedded directly in the token’s metadata rather than linked externally.

Can I use Multisig on OISY?

Yes, OISY supports multisig functionality in line with ICRC-2 standards. This allows users to pre-approve a specific amount that can be accessed by Dapps without further consent, enabling multiple transactions up to the approved limit.

If you have specific multisig needs that involve all users signing each transaction, please let us know so we can ensure compatibility and provide further assistance.

What is Network Custody?

Network custody is a cutting-edge approach to digital asset security that eliminates the traditional need for direct private key management by users. This method leverages the decentralized architecture of the Internet Computer, enhancing both security and usability.

How does Network Custody compare to traditional methods?

Unlike traditional self-custody, which requires users to safeguard their own private keys, and custodial services that pose risks of centralized control, network custody in OISY simplifies access while distributing security risks.

How is Network Custody implemented in OISY?

OISY utilizes threshold cryptography technology on the Internet Computer to split private keys into shares that are distributed across various nodes. This method ensures that no single node can access the complete key, significantly enhancing security during transactions.

What are the advantages of using Network Custody?

Network custody provides numerous benefits:

• Enhanced Security: By decentralizing key storage and using advanced cryptographic techniques, it becomes much harder for unauthorized users to access digital assets.

• Simplified Access: Users can authenticate via modern methods like biometrics—no need to remember complex passwords or seed phrases.

• Peace of Mind: Users no longer need to worry about losing keys or theft from personal devices.

• Cost-Effective: Reduces the need for extensive security infrastructure for businesses, lowering operational costs.

Connect with OISY to your app

For the OISY Wallet integration, here are a few options to explore:

Note: Older ledgers that do not support the ICRC-21 standard currently are not compatible with the OISY Wallet, but we are adding support for this in the coming weeks.

Prerequisites

Start the local replica

Dependencies

Some Iconly icons are used in the project, not included. You must obtain a license separately.

What are the unique ICP technical building blocks enabling the creation of OISY?

• Chain-key signatures: the world's best threshold ECDSA signature protocol suite (only available on ICP) enables smart contracts to perform cryptographic signatures without a single entity having full access to the private key. Read more about chain-key cryptography or start building based on chain-key signature sample code.

• Internet Identity (II): based on ICP's threshold BLS signature schemes and WebAuthn, Internet Identity (II) is an authentication and key management system with strong privacy and security guarantees. Using WebAuthn, users can conveniently create secure sessions with their fingerprint or other biometric identifiers. Read more about Internet Identity technology or start integrating II into your canister smart contract.

• Web applications served from chain: ICP is not only designed to run backends, such as ledgers, on chain, its low storage cost and low latency allow it to serve frontends, such as HTML files and images, from chain, too. Read more about smart contracts serving web applications or directly start building your first decentralized web frontend.

• (Upcoming) HTTP outcalls: for now, OISY calls centralized Ethereum endpoints, such as Infura or Alchemy, from the frontend. In the future, OISY might be improved to use HTTP outcalls to call these endpoints in a decentralized fashion. Check out the HTTP outcalls sample code to explore how to use Web 2.0 services on ICP.

OISY – the 1st fully-decentralized wallet for Bitcoin, Ethereum, Solana and ICP

OISY enables users to seamlessly manage and self-custody digital assets on multiple blockchains, simply by interacting with a rich web experience that is securely served directly into their web browsers by advanced smart contracts on the Internet Computer – without the need for web browser extensions and phone apps, which can be censored, and expose users’ private keys to danger.

Zurich, Switzerland — February 27, 9 AM ET — A revolutionary new wallet paradigm has transitioned into production: the DFINITY Foundation announces that Version 1.0 of the OISY wallet is live, as the result of its incubation of the project. OISY provides its functionality through a seamless web experience, which is served directly from the blockchain by advanced smart contracts. With OISY, the installation of risky wallet software such as web browser extensions and phone apps is not necessary, and users simply authenticate using modern passkey technology. By building on “chain key” crypto technology, OISY trustlessly integrates with Bitcoin, Ethereum, Solana and ICP, and support for more chains is planned. OISY’s source code is open source and verifiable.

A revolutionary wallet design addressing key risks

Traditional crypto wallets take the form of web browser extensions, and phone apps, which come with several risks. Firstly, browser extensions and apps must hold their users’ private keys in plaintext to sign transactions, which can expose them to malware running on users’ computers. Secondly, the distribution of browser extensions and apps can be censored by parties such as the Chrome Web Store, and the Apple App Store (which have both censored wallets in the past). Thirdly, malicious insiders at corporations providing these services can in principle maliciously alter wallet software. Fourthly, the user must trust that the developers who created the software did not deliberately, or inadvertently, include malicious software logic themselves. With OISY, users use passkeys to authenticate themselves to smart contracts via a web experience they serve directly. Passkey technology maintains authentication data, and signs sessions, inside special secure hardware on modern phones and laptops, which keeps it safe. Meanwhile, users’ tokens are held by the smart contracts themselves, using “chain key” technology. When the smart contracts must sign blockchain transactions for their users, independent blockchain nodes cooperate to create the signatures through consensus. OISY’s entire code - frontend and backend - is implemented as smart contracts running on ICP. This means that the code of OISY cannot only be publicly audited, it can also be publicly verified that the correct code is deployed and runs on the Internet Computer. Thus, the risks of key compromise, key loss, phishing attacks and third party failures are greatly reduced.

Totally seamless, multi-chain functionality

OISY isn’t just about improving security, it's also about providing a better user experience for those wishing to self-custody digital assets on multiple blockchains. Traditional crypto wallets require users to craft transactions themselves, a process that can be cumbersome, error-prone and difficult for non-technical users to accomplish. OISY provides a more seamless user experience, where user-friendly interactions with a web experience cause smart contracts to sign transactions on their behalf, requiring less work, and less skill. Because the smart contracts leverage “chain key” technology, they can trustlessly sign transactions for users on multiple blockchains – enabling OISY users to interact with tokens and decentralized applications (dApps) on Bitcoin, Ethereum, Solana and ICP. The user experience is far more seamless and greatly improved for novices and experienced crypto users alike.

Key Features:

• An exclusively in-browser wallet experience, which is richer, more friendly, and seamless, since users do not have to sign transactions manually

• A unified wallet for BTC, ETH, SOL, and ICP, with support for more networks coming

• Users authenticate to their fully decentralized wallet, served from chain via the URL oisy.com, using passkeys.

• The smart contracts that serve the user experience custody tokens for users, and sign transactions, using “chain key” technology.

• The wallet is built exclusively from advanced smart contracts running on the Internet Computer, in full decentralization, reducing censorship and security risks, and increasing resilience.

• Chain key technology is trustless, and multi-chain, allowing OISY to trustlessly manage tokens and interact with other blockchains without using bridging technology.

• Users authenticate to OISY using an Internet Identity, which allows users to associate multiple passkeys, and thus access their wallets from multiple devices, such as phones and laptops.

• Within the web experience, users can purchase new digital assets using fiat through a centralized onramper service that has been integrated.

• Within the web experience, users can swap digital assets with lighting speed through built-in swaps functionality that integrates with external DEXs.

• The wallet now drops random token rewards into eligible users wallets, to incentivize usage.

Delivering World Computer functionality using the Internet Computer

The “World Computer” is the amalgamation of all blockchains hosting tokens and smart contracts, and the overall vision is one of decentralization. The Internet Computer (ICP) is a blockchain with a unique architecture that helps realize this vision: it hosts advanced smart contracts that pay for their own computation (reverse gas), serve web experiences, process and store large amounts of data efficiently, and trustlessly interact with other blockchains using “chain key” cryptography. The Internet Computer is bringing the World Computer vision to life by enabling fully-decentralized, fully-onchain, and multichain experiences, such as OISY, to be created.

The “OISY Sprinkles” program provides exciting incentives to users To celebrate the release of Version 1.0, OISY is kicking off the “OISY Sprinkles” program. As part of this program, at unpredictable times, the OISY project will distribute semi-random quantities of well-known tokens, such as Bitcoin and ether, into users’ wallets, to reward them for their activity.

Dominic Williams, Founder and President of the DFINITY Foundation: "OISY provides a wonderful example of the World Computer paradigm, which is made possible by the next-generation crypto technology provided by ICP."

Akeel Qureshi, Core Contributor at OISY Wallet, stated: “Technology should feel invisible when it’s working at its best. No one thinks about the TCP/IP stack when they send an email, and no one should have to think about blockchain protocols when managing their assets. With OISY, we’re stripping away the barriers, reducing friction to nothing, and making decentralized finance as seamless as it was always meant to be.”

Pierre Samaties, Chief Business Officer at DFINITY, added: “OISY Wallet streamlines multi-chain asset management while increasing decentralization and security. By removing the complexity of key management, OISY makes multi-chain digital asset management accessible to a wider audience.”

About OISY Wallet

OISY is a fully-decentralized, fully-onchain, in-browser Web3 wallet providing multichain functionality. It is created by advanced smart contracts hosted on the Internet Computer (ICP) blockchain that serve web experiences to users, and can custody of their tokens using “chain key” technology. Users authenticate to the smart contracts over the web using passkey technology, and cause the smart contracts to seamlessly sign transactions for them through their interactions with the web experience.

About the Internet Computer

The Internet Computer is a blockchain network created by Internet Computer Protocol (ICP), whose main token is also called ICP. The technology involved was primarily developed by the DFINITY Foundation (founded 2016), and has benefited from more than 1000 person years of R&D effort to date, involving a world-famous, international team. Although the Internet Computer is a blockchain, it is designed to perform the role of a cloud computing platform that hosts a new form of advanced smart contract software within a serverless environment. Internet Computer smart contract software pays for its own compute using a “reverse gas” paradigm, can serve secure web experiences directly to end users, can process and store large amounts of data efficiently onchain, and can scale. In addition to traditional blockchain applications such as DeFi, the Internet Computer can host apps such as social networks, enterprise systems and AI, fully-onchain, in the form of smart contract software. This means that Web3 apps and services can be built with complete decentralization, greatly increasing censorship resistance, security, and resilience, and enabling full autonomy where required. The Internet Computer blockchain is powered by “chain key” technology, which also allows the smart contracts it hosts to trustlessly interact with tokens and smart contracts on other blockchains, without need for bridges.

The OISY Sprinkles program continues—with new ways to earn and new reasons to stay active. Episode 3 keeps the core structure from earlier phases while expanding rewards through referrals and giving the community a path to unlock what comes next.

Program Overview

OISY Sprinkles is designed to distribute tokens randomly but not without method. The initiative targets active users of the OISY Wallet, rewarding those who consistently engage with our platform.

How to Earn Sprinkles

We’re keeping the core rewards structure in place, so all active OISY users can continue earning as before::

• Hold: Maintain at least $20 worth tokens**

• Login: Check in at least once every 7 days.

• Transact: Complete at least two transactions every 7 days.

50 random airdrops occur each day based on wallet activity.

New: Referral Rewards

• When someone you refer deploys a new wallet, you earn 10% of their Sprinkles for the next 30 days.

• They still get 100% of their rewards—you just get a bonus on top.

• The more active friends you invite, the more Sprinkles you earn.

Introducing the Super Sprinkle

• Our highest daily reward is getting a new name: the Super Sprinkle.

• One drop per day will award ~$50 in BTC to five randomly selected users.

• Win a Super Sprinkle? Post about it, and you become eligible to win again.

Want us to extend the campaign?

Want OISY Sprinkles to keep going? So do we! If a set number of new, active wallets are deployed, we’ll extend the campaign into Episode 4.

Stay Active, Earn More

Whether you’re earning through activity, referring friends, or getting lucky with a Super Sprinkle, there’s more BTC up for grabs than ever. Keep using OISY Wallet, and you might just wake up to a surprise in yours.

• Safeguard Your Internet Identity: Only use it securely and judiciously to log into apps. Misuse can lead to permanent fund loss.

• Use Enhanced Security: Enable FaceID, TouchID, or security keys for additional protection..

• Decentralized Security with OISY: Fully on-chain and decentralized to eliminate third-party risks.

1. Open OISY Wallet at OISY.com.

2. Click ‘BUY’ on the main dashboard.

3. A new modal will appear with two dropdown menus labeled:

• ‘You Spend’ – Select the token you want to use for the purchase.

• ‘You Get’ – Choose the token you want to buy.

4. Enter the amount in either ‘You Spend’ or ‘You Get’, depending on whether you are specifying the amount you want to spend or the amount you want to receive.

5. In the ‘Buy via’ section, choose your preferred onramp provider from the dropdown menu.

6. (Optional) If you want to set up a recurring purchase, toggle ‘Repeat Payment’ on or off.

7. Under ‘Pay Using’, select your payment method (e.g., credit/debit card, bank transfer, or other available options).

8. Click ‘Continue’—you will be redirected to your selected third-party onramp provider.

9. Follow the provider’s instructions to complete the transaction (this may include KYC verification, entering payment details, and confirming the purchase).

10. Once the payment is confirmed, return to OISY Wallet—your purchased tokens should now appear in your wallet.

📌 Note: Processing times may vary depending on the onramp provider, payment method, and network congestion. Some providers may require additional verification before completing the transaction.

The OISY Sprinkles program began as part of the v1.0 launch of OISY Wallet—a campaign built to reward genuine user engagement with surprise token drops, distributed at random throughout the day to active wallets.

Episode 1 introduced a simple idea: if you use the wallet, you might just get sprinkled. Over the course of two episodes, that idea evolved.

Overview

OISY Sprinkles was designed to reward everyday usage: log in, make transactions, hold a balance—and you’re in. No forms, no claiming, no guessing. Just activity rewarded, quietly and fairly.

Eligibility Criteria

To qualify for rewards during either episode, users had to meet the following criteria within the 7 days prior to each drop:

• Login: At least once

• Transactions: Complete a minimum of two transactions

• Account Balance: Maintain at least $20 USD worth of tokens in your wallet at the time of each airdrop

These simple actions unlocked eligibility for 50 random airdrops every single day.

How It Works

Daily Airdrops: 10 random airdrops were conducted throughout each day. The timing of these drops was dictated by platform activity and user engagement, giving active users a higher chance of receiving a Sprinkle.

Allocation: 1,550 total reward instances occurred throughout the campaign.

Specific Rewards: Each day, 5 participants received ~$50 worth of tokens. The remaining rewards were distributed across 45 other drops.

Continued Eligibility: Winning once did not affect future chances—eligibility reset with each drop cycle.

Episode Breakdown

Episode 1 (Feb 29 – March 10)

The program began with ICP and ecosystem tokens as the primary rewards. This phase established the core criteria and reward format that defined the Sprinkles structure.

Episode 2 (March 11 – April 7)

On March 11th, the program transitioned into Episode 2 with the inclusion of BTC and USDC as a reward tokens. This change expanded the scope of Sprinkles while maintaining the same eligibility requirements and daily reward structure.

Goals of the Program

Enhance User Engagement: By rewarding basic actions like logging in and transacting, we encouraged frequent and meaningful use of the OISY Wallet.

Promote the ICP Ecosystem: Distributing ICP and ecosystem tokens highlighted the utility of assets within the network.

Surprise and Delight: Random token drops added an unexpected and exciting layer to daily platform activity.

Looking Back

This effort laid the foundation for what OISY Sprinkles would become—rewarding, accessible, and community-driven. Episodes 1 and 2 introduced the mechanics, tested the structure, and set the tone for what comes next.

As the program evolves, we carry forward the same intent: reward participation and make every interaction with OISY more valuable. A new version of Sprinkles is now live.

Can OISY access the private keys of native assets? Who controls the assets?

Who manages OISY canisters? What happens to assets if canisters run out of cycles?

Critically, user assets always reside on their respective ledgers on the respective blockchains rather than within these canisters. Even if OISY canisters were to be removed or replaced, the underlying assets remain secure and can be accessed by their owners again once new or replacement canisters are deployed.

If an OISY canister would deplete its cycles, it would simply become “frozen,” meaning the Internet Computer stops scheduling it until it’s refueled with cycles—a process that anyone can perform. However, the OISY Wallet team has procedures in place to always keep canisters fuelled, ensuring reliable and continuous access to assets.

What happens to wallet assets if the domain OISY.com expires or is hacked?

The domain OISY.com serves merely as a human-friendly pointer to the onchain frontend canister. Should the domain expire or be compromised and pointed elsewhere, the integrity of the assets remains intact as transfers can only be executed upon owner authorization via their Internet Identity.

Can I access the private keys of Ethereum/Bitcoin/Solana wallets?

OISY Wallet uses the Internet Computer’s cryptographic threshold protocols as well as key derivation. Therefore it is not possible to extract the private keys. This innovative design strengthens security while preserving user sovereignty over Ethereum, Bitcoin, and Solana assets and relieves the user from the difficult and error prone task of managing and securing cryptographic keys.

What are the Recovery Options in OISY?

Because your Internet Identity ultimately governs access to your funds, the most important recovery measure is to safeguard your Internet Identity. We recommend adding backup devices such as a YubiKey to your Identity and make use of the passkey recovery mechanisms that Apple and Google offer for their devices. This ensures you have multiple ways to securely restore access to your OISY-managed assets.

Will the community be able to participate in project governance?

Currently, development is managed by the OISY Wallet team, incubated by the DFINITY Foundation. For projects built on the Internet Computer—like OISY Wallet—there is a strong push toward decentralization. The community can expect future developments in this area—stay tuned.
