This guide explains how to move tokens between chains using Trust Wallet as your interface: from preparation to execution, what can go wrong, and how to recover stuck funds. If you want practical steps for how to swap bep20 to erc20 trust wallet, or to bridge tokens trust wallet across chains, you’ll find step-by-step procedures and safety tips here.

If you need help with installing Trust Wallet first, see the mobile setup pages: Install on iPhone and Install on Android.
A cross-chain bridge moves value between different blockchains by locking an asset on one chain and minting a representation on another (or by redeeming a wrapped token). BEP20 and ERC20 are token standards on Binance Smart Chain (BSC) and Ethereum respectively; they define how tokens behave on each chain. Why does this matter? Because a token's contract address and standard determine whether your wallet will show the balance automatically or if you must add a custom token after bridging.
For background on token mechanics and supported chains, see token-standards-and-bridges and multi-chain support.
Trust Wallet is a hot software wallet that holds your private keys locally and can act as the signer when you use bridge dApps. But one subtle point: an in-wallet swap typically stays on the same chain. Cross-chain transfers usually require a bridge dApp (accessed via the in-app dApp browser where available) or WalletConnect to connect your mobile wallet to external bridge sites.
In my experience, on Android the in-app dApp browser streamlines the flow. On iPhone I often use WalletConnect to link Trust Wallet to a bridge page in Safari (Apple's rules limit some in-app browsers). What I've found makes a real difference is doing a tiny test bridge first (more on that below).
| Method | How it works | Pros | Cons |
|---|---|---|---|
| In-app swap (same chain) | On-chain swap between tokens on same blockchain | Fast, low friction | Can't change token standard (no cross-chain) |
| Bridge dApp (via in-app browser / WalletConnect) | Lock & mint or burn & release across chains | Non-custodial, broad chain support | Longer wait times, more risk if bridge contract is malicious |
| Custodial transfer (exchange) | Send token to exchange, withdraw on other chain | Familiar UX, support available | Custodial custody, KYC, withdrawal limits |

This is a generic sequence for bridging tokens trust wallet to another chain. Exact screens depend on the bridge dApp you choose.

If you want to remove a token approval after the bridge, use the guide: revoke token approvals.
What if the token never appears? First, don't panic. Follow these steps in order:
If you still get stuck, my go-to is to gather evidence (TX hashes on both chains) and then follow the troubleshooting checklist at troubleshooting.
Bridges are attractive targets. Here are things to watch for:

Q: Is it safe to keep crypto in a hot wallet?
A: Hot wallets trade some security for convenience. They work well for active DeFi use, but for large, long-term holdings a hardware wallet reduces risk. See security-best-practices and ledger-hardware.
Q: How do I revoke token approvals?
A: Use the revoke guide: revoke-approvals-and-allowances. Revoke the approval contract on the chain you used to bridge.
Q: What happens if I lose my phone?
A: If you have a seed phrase backup you can restore your wallet on another device. For detailed steps, see lost-phone-recovery. Never store the seed phrase in cloud notes without encryption.
Bridging is powerful but adds attack surface and complexity compared with same-chain swaps. My practical advice: always do a small test transfer, check contract addresses twice, and keep transaction hashes handy in case you need help. If you want more step-by-step coverage of related features, read the in-wallet swap overview and the cross-chain bridges page.
If you're ready to bridge, start with a small test amount and follow the checks above. And if you run into trouble, the troubleshooting links in this guide are where to start.
