Quick overview
This guide shows how to swap tokens inside the Trust Wallet mobile app, with a focus on aggregator routing and the settings that change final outcomes: slippage, deadlines, and gas. I use the app daily for small DeFi swaps and staking interactions, so these are practical, tested steps (and yes, I have had one swap fail because I forgot to add native gas funds). Want to know how to swap any coin on Trust Wallet or specifically how to swap coins on Trust Wallet when the token is BEP20? Read on.
Step by step: How to swap any coin on Trust Wallet (mobile)
- Open the Trust Wallet app and unlock with your PIN or biometric.
- Tap "Swap" or "DEX" from the bottom menu (the label can vary by version).
- Select the token you want to send (From) and the token to receive (To). If the token is not visible, use the token search or add a custom token via add-custom-token.
- Tap the settings/cog icon (top-right or near the amount). Adjust slippage tolerance and transaction deadline if needed.
- If the token requires a token approval (common for BEP20/ERC20), the app will prompt to approve before swapping. Confirm the approve transaction.
- Review the route summary shown by the aggregator (it may list multiple pools or DEXs). Check price impact and minimum received.
- Confirm the swap and pay the gas fee (BNB for BNB Smart Chain swaps; ETH for Ethereum). Keep a small native balance for gas.
- After submission, tap the transaction to view details or open a block explorer link.
Step-by-step screenshots can help here (placeholder above). But the core steps are universal across recent app builds.
What the built-in swap aggregator does (routing explained)
An in-wallet swap aggregator queries multiple liquidity sources and chooses a route that aims to get the best execution price. That can mean splitting your trade across two pools to reduce price impact, or using a pool with deeper liquidity. Why does that matter? Because a single DEX route can show worse price impact than a combined route.
In my experience the aggregator often picks a split route for mid-size trades; small swaps usually stay on one pool. (Curious? Try a tiny swap and then a larger one and compare "minimum received".)
Note: the aggregator is not magic. It cannot avoid bridge or cross-chain steps unless you explicitly use a cross-chain bridge feature. For cross-chain flow guidance see cross-chain-swaps-bep20-erc20.
Slippage, deadlines, and gas settings — practical tips
Slippage tolerance controls how far the execution price can move before the transaction reverts. Typical guidance:
- Stablecoin-to-stablecoin: 0.1%–0.5% slippage.
- Low-liquidity or meme tokens: 1%–5% (or more, if accepted).
- Very thin markets: you may need double-digit slippage, but this carries risk.
Why increase slippage? To prevent a transaction from failing when price moves between signing and execution. But watch out: higher slippage means a worse guaranteed minimum.
Deadlines (transaction timeout) are measured in minutes. A short deadline (2–5 minutes) reduces risk if a front-run or sandwich attack is a concern. A longer deadline can help if the network is congested.
Gas fees: on Ethereum the wallet may show EIP-1559 fields (max fee and priority fee) or simple presets (slow/average/fast). On Layer 2 networks gas is usually much lower. If you want deeper reading, see gas-fees-management.
But don't forget: set slippage first, then gas. Incorrect slippage is a frequent reason swaps fail.
Swapping BEP20 tokens on Trust Wallet — gotchas
If you're swapping BEP20 tokens on the BNB Smart Chain, remember:
- Gas is paid in BNB (native token). Keep some BNB on hand before any swap.
- Some tokens share names or tickers; verify the contract address when adding a custom BEP20 token.
- Cross-chain tokens (wrapped versions) may require a bridge; a simple in-app swap won't move tokens between chains.
If you want a guided BEP20 swap walkthrough, see swap-bnb or the general how-to-swap-tokens page.
Approvals, safety checks, and revocation
Most ERC20/BEP20 tokens require you to first approve the DEX contract to spend your tokens. That creates a token allowance (token approval). Approvals can be limited (exact amount) or unlimited. Unlimited approvals are convenient but increase exposure if a contract is compromised.
I once approved a token and forgot to revoke it. Lesson learned: check allowances regularly. Use the guide on token-approvals-revoke to remove dangerous allowances.
Quick safety checklist before swapping:
- Confirm token contract address (official site or block explorer).
- Check price impact and minimum received.
- Keep native chain balance for gas.
- Consider reducing allowance after large one-off swaps.
If a swap fails: troubleshooting checklist
Common failure modes and fixes (short checklist):
- "Insufficient gas": Add native chain token (BNB/ETH) and retry.
- "Swap failed" with high slippage: Increase slippage slightly.
- "Token not found" in swap list: Add via add-custom-token or use dApp browser.
- Pending a long time: view tx on block explorer and check gas price. If the wallet doesn't support replacing a transaction, you may need to wait or use a node to speed it up.
If you need a deeper run-through, see swap-troubleshooting. And don't panic if something fails; most issues have a fix.

Who this wallet is best for / who should look elsewhere
Best for:
- Mobile-first users who swap and stake occasionally.
- People who want an integrated mobile swap experience with quick access to tokens.
Look elsewhere if:
- You need enterprise-grade trade automation or batched advanced orders.
- You strictly require on-device transaction simulation or advanced nonce control.
I believe Trust Wallet is a useful hot wallet for active mobile DeFi use, but it isn't a substitute for hardware wallets when you hold large sums.
FAQ
Q: Is it safe to keep crypto in a hot wallet?
A: Hot wallets are convenient and non-custodial, but they expose private keys to a connected device. For large holdings a hardware wallet is safer. For daily use, a small hot-wallet balance is pragmatic.
Q: How do I revoke token approvals?
A: Use the guide at revoke-approvals to find and remove allowances.
Q: What happens if I lose my phone?
A: Restore with your seed phrase on a new device (see restore-import-wallet). Keep the seed phrase offline and protected.
Q: Swap failed but my tokens were debited — what now?
A: Check the transaction on a block explorer and contact support (see support-contact). Also review swap-troubleshooting.
Conclusion & next steps
Swapping inside the Trust Wallet mobile app is fast and usually efficient because the in-app aggregator picks routes across liquidity sources. Pay attention to slippage, deadlines, and native gas balances. I recommend testing with small amounts first — I've done that many times — and then scaling up when the flow is proven.
For deeper help, read the step-by-step swap troubleshooting page (swap-troubleshooting), learn about managing tokens (token-management), or review gas fee strategies (gas-fees-management).
But remember: hot wallets trade convenience for exposure. Keep seed phrases safe and only keep what you need for daily activity.
