# How to "Connect with OISY"

## Connect with OISY to your app

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

* For React frontends, the [IdentityKit](https://nfid-identity-kit.webflow.io/) ([npm](https://www.npmjs.com/package/@nfid/identitykit), [documentation](https://qzjsg-qiaaa-aaaam-acupa-cai.icp0.io/docs)) and related [demo](https://qzjsg-qiaaa-aaaam-acupa-cai.icp0.io/demo) would be a great place to start. It’s like a WalletConnect for the Internet Computer.
* For Typescript, take a look at [@icp-sdk/signer](https://www.npmjs.com/package/@icp-sdk/signer) (which is the underlying library for IdentityKit).
  * Note: This library used to be at [@slide-computer/signer](https://www.npmjs.com/package/@slide-computer/signer) and was moved to the new repo under direct Dfinity maintenance early 2026
* We also provide a reference implementation, [@dfinity/oisy-wallet-signer](https://www.npmjs.com/package/@dfinity/oisy-wallet-signer). Its features are more opinionated and limited to transfers or approvals with ICP or ICRC ledgers, so for a more general-purpose solution, the above two options might be a better fit.
  * Demo app is here: <https://shsda-3aaaa-aaaal-amg6q-cai.icp0.io/> (link is also available in the github repo)

**Note**: OISY implements a default handler for `icrc2_approve` and `icrc2_transfer_from` messages and can display a consent message for these two methods in case the ledger does not implement the ICRC-21 standard.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.oisy.com/for-developers/how-to-connect-with-oisy.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
