OP Stack interoperability is the next major scalability improvement to the OP Stack which enables a network of chains to feel like a single blockchain. This revolutionary approach unlocks 1-block latency and trust-minimized cross-chain composability.

​
What is OP Stack Interoperability?

OP Stack interoperability enables:
  • Native asset transfers: ETH and ERC-20 tokens move securely between chains via native minting and burning
  • Cross-chain composability: Smart contracts can compose with data across multiple chains
  • Horizontal scalability: Applications can scale across multiple chains seamlessly

​
Key Benefits

Eliminates liquidity fragmentation by enabling native asset transfers without wrapping or liquidity pools

Enhanced UX

Users experience seamless cross-chain interactions without complex bridging processes

Developer Flexibility

Build applications that can leverage resources and data from multiple chains

Scalability

Horizontal scaling across multiple chains while maintaining security
