MetaMask's built-in aggregated cross-chain bridging feature, Bridge, has received a major upgrade this month. Users can now execute token swaps and cross-chain transfers in a single transaction, with significantly expanded token support.
Full Asset Support on MetaMask Bridge
Bridge is MetaMask's native aggregated cross-chain solution, allowing users to select routes based on priorities like lowest cost or fastest transfer time. Since its late 2022 launch, it has facilitated:
- 300,000+ user transactions (Dune Analytics data)
- $300 million in cross-chain volume
The new upgrade introduces simultaneous swap-and-bridge functionality, enabling direct conversion between native tokens of different networks without intermediate steps. For example:
- Convert ARB on Arbitrum directly to OP on Optimism
- Trade MATIC on Polygon for AVAX on Avalanche in one action

✔ Minimal-trust design
✔ Atomic transactions
✔ External validator verification
