How to bridge assets between chains

Written by XAUConnect Labs · Reviewed against live product behavior · Updated 16 October 2026

How to bridge assets between chains: choose the source, the destination, and the two token contracts, then sign only if the quoted arrival amount is enough.

You need the source gas coin to send and the destination gas coin after the tokens arrive. The object that arrives has a different address. Check it on the destination explorer before you trade it.

A reason to stop

If you only wanted to swap USDC for ETH on Ethereum, do not bridge. A same-chain swap is one market. A bridge is two markets and a wait, and this site will not promise how long the wait is.

What has to be true before you sign

You can pay gas on the source chain, and you will be able to pay gas on the destination. You have checked both token addresses. If either check fails, stop. The mechanism is how cross-chain bridges work. A same-chain pair does not need this guide.

Frequently asked questions

What is the best way to bridge assets between chains?

You need the source gas coin to send and the destination gas coin after the tokens arrive. The object that arrives has a different address.

The tokens arrived and I cannot move them. Why?

You have no gas coin on the destination chain. Bridge or buy a small amount of that native coin, then move the tokens.
