Multi-Chain Support: Expanding to Arbitrum and Polygon

Multi-chain support is central to Cornicular's architecture. In this post, we detail our approach to deploying across multiple blockchain networks and the technical challenges we solved along the way.

Why Multi-Chain?

Different users have different needs. Some require the maximum security of Ethereum mainnet. Others need the cost efficiency of Layer 2 solutions. By supporting multiple chains, we let users choose what works best for their use case.

Deployment Strategy

Our smart contracts are deployed as EVM-compatible bytecode, which means the same contract logic works across Ethereum, Base, Arbitrum, Polygon, and Optimism. However, each chain has unique characteristics that require careful consideration.

We use a chain abstraction layer in our backend that normalizes interactions across different networks. This means our API consumers do not need to worry about chain-specific details. The system handles chain selection, gas estimation, and transaction routing automatically.

Cross-Chain Verification

When a document is registered on one chain, it can be verified against that specific chain's record. Our verification engine queries all supported chains in parallel, returning results in under 600 milliseconds regardless of which chain holds the record.
