Build Cross-Chain Applications on CDK

AggLayer is built into every Chain Development Kit (CDK) chain. You can work with AggLayer’s cross-chain capabilities in development and production without setting up separate interoperability infrastructure.

What you can build on CDK chains

  • Atomic cross-chain operations: Execute operations across multiple chains in a single transaction
  • Unified asset management: Build applications where users’ assets work across all supported chains
  • Cross-chain smart contracts: Create contracts that trigger actions and transfer value across different networks
  • Multi-chain interfaces: Build UIs that abstract chain selection away from the user

Next steps

  • Supported chains: See which chains are connected to AggLayer, with RPC endpoints and chain IDs.
  • Integrations: Use Bridge Hub or the AggKit Bridge Service to query bridge data, generate claim proofs, and automate claiming across chains.
