Core Bridge Resources

---

The Core Bridge is powered by LayerZero, and enables seamless asset transfers between Core and the wider blockchain world.

The Core Bridge consists of two parts:

• LayerZero contracts on Core that facilitate cross-chain transfers and
• Set of bridge or token contracts deployed both on Core and each blockchain it’s connected to.

The audited bridge codebase can be found here, and here is the full list of bridge token contract addresses
