How to use WalletConnect with Trust Wallet? (dApp Connection)

Understanding WalletConnect Protocol

1. WalletConnect is an open-source protocol that enables secure communication between decentralized applications and cryptocurrency wallets without exposing private keys.

2. It uses end-to-end encryption and establishes a bridge connection via QR code scanning or deep linking.

3. Trust Wallet fully supports WalletConnect v1 and v2, offering compatibility with thousands of dApps across Ethereum, BSC, Polygon, Solana, and other EVM-compatible chains.

4. The protocol does not store session data on centralized servers; instead, it relies on relay servers to forward encrypted payloads between the dApp and wallet.

5. Users retain full control over transaction signing—no third party can initiate or approve actions without explicit user confirmation inside Trust Wallet.

Initiating Connection from a dApp

1. Navigate to a WalletConnect-enabled dApp in your mobile or desktop browser.

2. Click “Connect Wallet” and select “WalletConnect” from the list of available options.

3. A QR code appears on screen—this contains an encrypted session proposal with chain ID, metadata, and required permissions.

4. Open Trust Wallet, tap the hamburger menu (☰), then select “WalletConnect”.

5. Use the built-in camera to scan the QR code; the app will display the dApp’s name, requested network, and permission scope before prompting approval.

Managing Active Sessions in Trust Wallet

1. Go to the WalletConnect section under the side menu to view all currently connected dApps.

2. Each entry shows the dApp’s icon, domain, last used timestamp, and associated blockchain network.

3. Tap any session to review active permissions, switch networks, or disconnect immediately.

4. Disconnecting revokes the dApp’s ability to request transactions or read wallet addresses without re-scanning.

5. Sessions persist across app restarts unless manually terminated or expired due to inactivity after 7 days.

Signing Transactions via WalletConnect

1. After connection, interact with the dApp as usual—swap tokens, stake, mint NFTs, or vote in governance.

2. When an action requires on-chain execution, Trust Wallet displays a detailed transaction preview including gas fee, recipient, function call, and value transfer.

3. Users must manually confirm every transaction inside Trust Wallet—no automatic approvals are permitted.

4. If the dApp requests access to specific token balances or contract interactions, those details appear under “Permissions” before signing.

5. Failed transactions remain visible in the activity log with error codes such as “user rejected”, “insufficient balance”, or “network mismatch”.

Frequently Asked Questions

Q: Can I use WalletConnect with Trust Wallet on desktop?A: Yes—Trust Wallet offers a desktop version compatible with WalletConnect. Install the official Trust Wallet Desktop app, enable WalletConnect in settings, and scan QR codes using the integrated camera or paste pairing URIs manually.

Q: Why does my dApp show “Unsupported Chain” after connecting?A: Trust Wallet may not have the target network pre-configured. Go to Settings → Networks → Add Network and input RPC URL, chain ID, symbol, and block explorer URL for the required chain.

Q: Does WalletConnect expose my seed phrase to the dApp?A: No—WalletConnect never transmits or requests seed phrases. It only shares public addresses and relays signed transaction payloads after local cryptographic signing inside Trust Wallet.

Q: Can I connect multiple wallets simultaneously via WalletConnect?A: Trust Wallet allows only one active WalletConnect session per dApp domain at a time. To switch accounts, disconnect the current session and reconnect using another wallet address.
