Retrieve a wallet address

Retrieve your user wallet without a backend

With Cometh Connect, you can retrieve the walletAddress of your user without interacting with a backend.

To do so, you'll need to let your user sign with one of the passkeys that was used to create a wallet. With the signature, we'll be able to retrieve and send back the wallet address linked to the user.

This is the code needed to implement that feature.

TS

import { retrieveAccountAddressFromPasskeys } from "@cometh/connect-sdk-4337";

const apiKey = process.env.COMETH_API_KEY;
const chain = gnosis;

const walletAddress = await retrieveAccountAddressFromPasskeys({apiKey, chain});

The user will have to select the passkey and sign a message in order to retrieve the wallet address.

He will then be able to connect to the wallet.
