# 3.5 Cross-Chain Interoperability and L2 Efficiency

The ABE is chain-agnostic. While the core security logic is anchored on Ethereum, the daily transaction clearing is offloaded to high-performance Layer 2s:

* **Base & Arbitrum Integration:** These chains provide the 200ms confirmation times required for real-world POS (Point of Sale) systems.
* **CCIP Implementation:** Utilizing Chainlink’s Cross-Chain Interoperability Protocol, a user can hold assets on Solana or Polygon and have them "bridged" into the AbyssPay clearing layer on Base in a single transaction.
