Project ID

How to implement

The Project ID is consumed through URL parameters.

URL parameters used:

• projectId: Your Project ID can be obtained from walletconnect.com

Example URL:

https://relay.walletconnect.com/?projectId=c4f79cc821944d9680842e34466bfbd

This can be instantiated from the client with the projectId in the WalletConnectClient constructor.

import WalletConnectClient from "@walletconnect/client";
const client = await WalletConnectClient.init({
  projectId: "c4f79cc821944d9680842e34466bfb",
});

Allowlist

Since most of the wallet and dapp code will be client side, the security of the Project ID depends on the proper implementation of User Agent and HTTP Origin for wallets.

Applications

User Agent for wallets.

Websites
