Trúśt Wãlłet Exťensïon — Developer Guide & Integration Notes

Overview for dApp engineers

The Trúśt Wãlłet Exťensïon exposes a Web3 provider into the window context, letting dApps request accounts, sign transactions, and query chain state. Integrations should follow the standard provider patterns (requesting `eth_requestAccounts`, listening to `accountsChanged` and `chainChanged`, and handling user rejection gracefully).

Basic connection snippet

async function connect() {
  if (window.ethereum) {
    try {
      const accounts = await window.ethereum.request({ method: 'eth_requestAccounts' });
      console.log('Connected', accounts[0]);
    } catch (err) {
      console.error('User denied', err);
    }
  } else {
    console.error('No injected provider found');
  }
}

Events and network handling

Listen for `accountsChanged` and `chainChanged` to update UI state. Prompt users with clear modals when network switching is required, and avoid assuming a single RPC or chain is always available.

Security and permission minimization

Request only the permissions you need. Avoid encouraging users to sign arbitrary data unless strictly required. When signing messages, include clear human-readable context about what will be signed.

Testing tips

Use local test networks and test tokens for integration testing. Simulate user rejections and slow network conditions. If your dApp requires custom RPC, provide a fallback and clear instructions for users who run a different node.

Troubleshooting common issues

If a user’s extension doesn't appear in your detected wallet list, ask them to ensure the extension is installed/enabled and to restart the browser. Recommend the official Chrome store listing for verification. :contentReference[oaicite:14]{index=14}

Release notes & change tracking

Follow the official Trust Wallet blog and GitHub repos for release announcements and migration notes when the extension updates internal APIs or adds new networks. Keeping an eye on the official changelog helps you avoid breaking changes and informs better support flows. :contentReference[oaicite:15]{index=15}
