If you searched for "warning deep link is not supported trust wallet" or "invalid wallet connect uri trust wallet" (or landed here from a message that said "no connected web3 wallet detected trust wallet"), this article walks through practical fixes. I use Trust Wallet daily and have hit these exact errors when connecting to dApps via WalletConnect or the in-app browser. Short version: the problem usually comes from how the dApp is calling your wallet (deep link vs injected provider), a truncated WalletConnect URI, or the mobile OS not routing the request to the app.
Why does that matter? Because you can't approve transactions or view balances if the site can't talk to your wallet. And yes, that has cost me time and some gas while I sorted connections.
Try these in order. Each is low-risk and often resolves the error immediately.
Short tech background. WalletConnect works in two common ways: QR/URI handoff and deep links (a special URL that tells your phone to open the wallet app). On desktop, sites often render a QR code. On mobile, sites try to open the wallet via a deep link like trust://wc?uri=... or rely on the wallet's DApp browser (which injects a web3 provider). If the OS or browser blocks the deep link, or the URI gets truncated, the dApp will show errors such as "deep link not supported" or "invalid wallet connect uri".
Common causes:
iOS handles universal links strictly. If a deep link isn’t opening the wallet, try this sequence:
But here's the catch: iOS updates can temporarily change behavior. If reinstallation and using the in-app browser don't help, try scanning a QR on a desktop site instead.
Android generally handles deep links more flexibly. Try these steps:
And yes, I ran that test on Android: scanning the QR resolved a deep link failure that opening the site from Chrome did not.
Specific example: some users see "deep link not supported PancakeSwap" when they try to connect from a mobile browser. Why? PancakeSwap often expects WalletConnect or an injected BSC-compatible provider. Steps that worked for me:
If you get an invalid URI when trying to paste a link from a message, re-copy the full WalletConnect URI from the dApp (or use the QR). See /connect-pancakeswap for pairing tips.
If you see "invalid wallet connect uri trust wallet":
If the dApp shows "no connected web3 wallet detected trust wallet":
For token safety after any unexpected connection, review approvals and revoke any suspicious allowances: see /token-approvals-revoke.
I tested connect flows across multiple dApps. Results in short:
One time I copied a WalletConnect URI from a Telegram message and received an "invalid wallet connect uri" error. After re-copying the full string from the dApp and pasting into the wallet, the connection succeeded.

| Error message | Most likely cause | Quick fix |
|---|---|---|
| "Deep link not supported" | Deep link handler not registered or blocked | Open dApp in wallet browser or scan QR |
| "Invalid WalletConnect URI" | URI truncated or malformed | Re-copy full URI or use QR scan |
| "No connected web3 wallet detected" | Site expects injected provider | Open site in wallet's DApp browser or use WalletConnect QR |
Who this helps:
Who should look elsewhere:
Q: Is it safe to keep crypto in a hot wallet?
A: Hot wallets are convenient for daily DeFi activity. For large, long-term holdings consider a hardware wallet. (Backups: keep your seed phrase offline and safe.)
Q: How do I revoke token approvals after a bad dApp connection?
A: Use the revoke approvals guide: /token-approvals-revoke. I’ve revoked an unlimited allowance after a suspicious approval; it’s quick and lowers risk.
Q: What happens if I lose my phone while troubleshooting deep links?
A: As long as you have your seed phrase and it is secure, you can restore the wallet on another device. See /restore-import-wallet and /lost-device-recovery.
Q: How do I fix "invalid wallet connect uri trust wallet" now?
A: Try QR scan first. If the dApp only provides a long URI, copy it from the dApp (not from a chat) and paste it into the wallet. Also update the app and clear cache.
Deep link and WalletConnect errors are frustrating but usually solvable without losing funds. Start with the wallet's DApp browser or a QR scan. If you still see messages like "warning deep link is not supported trust wallet" or "no connected web3 wallet detected trust wallet", follow the OS-specific steps above, re-copy the URI, and check app defaults. For persistent problems, clear cache or reinstall after backing up your seed phrase, and contact support if needed: /support-contact.
