How to Bridge Tokens Between Chains

Overview

Move your crypto between Ethereum, Arbitrum, Optimism, Polygon, and other chains using bridges. Learn the safest methods, cheapest routes, and how to avoid bridge exploits. Safe bridging starts with a secure wallet — read our wallet guides and security best practices before moving large sums across chains. Once your tokens land on the destination chain, put them to work in DeFi protocols or track them with a portfolio tracker.

Steps

1. 1Decide the source chain and destination chain (e.g., Ethereum → Arbitrum).
2. 2Choose a reputable bridge: official chain bridges (safest), Stargate, Across, or Hop Protocol.
3. 3Connect your wallet to the bridge dApp and select the token and amount.
4. 4Review the fee and estimated time — official bridges can take 7+ days for withdrawals.
5. 5Approve the token and confirm the bridge transaction.
6. 6Switch your wallet to the destination chain and verify your tokens arrived.

Pro Tips

• Always bridge a small test amount first before moving large sums.
• Use aggregators like LI.FI or Socket to find the cheapest and fastest route.
• Ensure you have gas tokens on the destination chain before bridging (you need them to do anything).
