Things To Remember
- Bridges allow assets to move between blockchains by locking on one and minting on another.
- Bridges have been exploited for billions of dollars — they are high-risk smart contracts.
- Always research a bridge's security audits before using it.
- Wrapped tokens (e.g. WBTC) represent bridged assets on another chain.
