TronLink WalletConnect v2 Mobile Linking / Deep Link and Return-to-DApp Support

[hanyueqiang]

Hi TronLink team,

We are integrating TRON USDT payments in a mobile checkout flow and would like to verify TronLink's current WalletConnect v2 support.

Our intended flow is:

1. A mobile DApp or native application creates a WalletConnect v2 pairing URI.
2. The DApp uses a TronLink-specific mobile deep link to open the TronLink app directly with that pairing URI.
3. The user approves the WalletConnect session and confirms a TRON/TRC-20 transaction in TronLink.
4. After the session approval, transaction approval, rejection, or completion, TronLink redirects the user back to the originating DApp/application via its registered redirect URL or custom scheme.

Could you please confirm:

• Does the TronLink mobile app support WalletConnect v2 pairing for TRON sessions?
• Is there an official TronLink mobile-link/deep-link format for a WalletConnect pairing URI, for example a documented equivalent of wallet://wc?uri=<encoded-pairing-uri>?
• Is TronLink registered in WalletConnect Explorer/AppKit for TRON WalletConnect v2? If yes, what wallet ID or integration configuration should DApps use?
• Does TronLink support redirecting back to the originating application after:
  • session approval or rejection;
  • transaction approval or rejection;
  • transaction broadcast/completion?
• If return-to-DApp is supported, what redirect metadata or custom-scheme / Universal Link / Android App Link configuration must the originating application provide?
• Are there any platform limitations for Android, iOS, or browser-based DApps such as Chrome/Safari?
• Is this flow supported on both TRON Mainnet and Nile Testnet?

We tested a generic WalletConnect/AppKit flow, but TronLink was not available in the wallet selection list. We would prefer a documented, TronLink-specific integration rather than relying on an undocumented deep-link scheme.

Thank you for any official documentation, sample code, or recommended SDK configuration.

Hi,

Thank you for reaching out. Current status:

• TronLink Mobile supports WalletConnect v2 TRON sessions on both Android and iOS through QR-code pairing.
• Supported methods are tron_signTransaction and tron_signMessage.
• A WalletConnect-specific TronLink deep link is not available in the current Android or iOS release, but support is planned for both platforms in an upcoming version.
• The final deep-link format, return-to-DApp behavior, and release timeline will be published in the official documentation.
• TronLink is not currently listed in WalletConnect Explorer/WalletGuide, so no wallet ID is available yet.
• tron_signTransaction returns a signed transaction; the DApp is responsible for broadcasting it and monitoring confirmation.
• Mainnet and Nile are supported when TronLink is on the matching network.

For now, please use QR pairing with [@tronweb3/walletconnect-tron](https://github.com/tronweb3/walletconnect-tron), or TronLink’s documented [DeepLink protocol](https://docs.tronlink.org/mobile/deeplink/) for same-device TRC-20 payments.

Please do not rely on an undocumented WalletConnect deep-link format before the feature and integration guide are officially released.
