Moving tokens from one blockchain to another usually requires a cross-chain bridge. The Cross-Chain Bridge tool lets you transfer crypto and tokens between Ethereum, Polygon, Arbitrum, Base, and 20+ chains—powered by LI.FI for secure, fast bridging. You connect your wallet, select source and destination chain, choose token and amount; you pay gas on the source chain and may receive wrapped or bridged assets on the destination.
What is a cross-chain bridge?
A cross-chain bridge lets you transfer tokens from one blockchain to another. For example, you can bridge ETH from Ethereum to Polygon or Arbitrum. This tool supports 20+ chains including Ethereum, Polygon, Arbitrum, Base, Optimism, Avalanche, BNB Chain, and more. It uses LI.FI, a trusted aggregator that routes through audited bridges—always verify amounts and destination addresses before confirming. You need to connect your wallet, select source and destination chain, choose token and amount; you pay gas on the source chain and may receive wrapped or bridged assets on the destination. You connect your wallet to sign transactions; the bridge may route through third-party providers—read the tool's privacy policy and LI.FI terms. If your bridge takes a long time, bridging depends on source and destination chain finality and the bridge provider; some bridges batch transfers—check the provider's estimated time.
Key Features
- What it is — A bridge lets you transfer tokens from one chain to another (e.g. ETH from Ethereum to Polygon).
- Chains — 20+ chains: Ethereum, Polygon, Arbitrum, Base, Optimism, Avalanche, BNB Chain, and more.
- Safety — Uses LI.FI aggregator routing through audited bridges. Always verify amounts and destination address.
- What you need — Connect wallet, select source and destination chain, choose token and amount. Pay gas on source chain; may receive wrapped/bridged assets on destination.
- Privacy — You connect your wallet to sign. Bridge may route through third-party providers. Read the tool's privacy policy and LI.FI terms.
- Slow bridge — Depends on chain finality and provider. Some bridges batch transfers; check provider's estimated time.
How to Use the Cross-Chain Bridge
- Open the Cross-Chain Bridge tool.
- Connect your wallet. Select source and destination chain. Choose token and amount. Confirm and sign. Pay gas on source chain.
- Use the "Use tool" button on the docs page if you are reading this from the documentation.
Real Use Cases
- Move ETH to L2 — Bridge from Ethereum to Polygon, Arbitrum, or Base. Use with Increase Transaction if you want to add tx count on destination chain.
- Multi-chain DeFi — Use assets on another chain. Bridge then interact with dApps. Use with Increase Transaction.
- Airdrop or activity — Get gas on a new chain via bridge. Then use Increase Transaction for check-in.
- Documentation — Show users how to bridge. Use tool as reference.
- Support — Explain bridging time and destination. Check provider's estimated time.
- Testing — Bridge testnet or small amounts. Verify destination address and amounts.
Why Use the Cross-Chain Bridge Instead of Alternatives?
- vs. Increase Transaction — Increase Transaction adds a check-in tx. This tool moves tokens between chains. Use bridge for moving funds; use increase-transaction for tx count.
- vs. CEX — Deposit, withdraw, and swap on an exchange can achieve similar result but off-chain. Bridge keeps assets on-chain and uses LI.FI.
- vs. Manual bridge — One tool, 20+ chains, LI.FI aggregation. No need to find each bridge manually.
Benefits for Users and DeFi Users
- Users — Move tokens between chains in one place. LI.FI aggregation for routes.
- DeFi users — Get assets on L2 or other chains for farming, lending, or trading.
Common Mistakes
- Bridge took long — Bridging depends on source and destination chain finality and the bridge provider. Some bridges batch transfers; check the provider's estimated time.
- Wrong destination — Always verify destination address and chain. Transactions are irreversible.
- Expecting instant — Finality and provider batching can delay. Check estimates.
- Privacy — You connect your wallet to sign; bridge may route through third parties. Read the tool's privacy policy and LI.FI terms.
