How to Use Layer 2 Bridges: Complete Guide

Layer 2 networks offer cheaper, faster transactions. Here's how to move your assets there safely.

What is Bridging?

Bridging moves assets from Ethereum (or other chains) to Layer 2 networks. Your assets are locked on L1 and equivalent tokens are minted on L2.

Popular L2 Bridges

  • Arbitrum Bridge: bridge.arbitrum.io
  • Optimism Gateway: app.optimism.io/bridge
  • Base Bridge: bridge.base.org
  • Polygon Bridge: wallet.polygon.technology

How to Bridge (Arbitrum Example)

  1. Go to bridge.arbitrum.io
  2. Connect your wallet
  3. Select asset and amount
  4. Click 'Move funds to Arbitrum'
  5. Confirm transaction and wait 10-15 minutes

Bridge Aggregators

For best rates, use aggregators like:

  • Jumper.exchange
  • Bungee.exchange
  • Socket (via various apps)

Tips

  • Bridge during low gas periods
  • Keep some ETH on L2 for gas
  • Withdrawing to L1 can take 7 days (optimistic rollups)
