**Proposal to Integrate Aztec into the TRAIN Protocol**

The TRAIN Protocol uses an intent/solver based system secured by Atomic Swaps and Local Verification. This ensures uniform, trustless security across all chains. This allows any network to integrate under the same security framework, enabling infinite scalability.

**We are excited to bring confidential cross-chain bridging with Aztec.**
