We build and optimize cross-chain infrastructure for moving assets and messages between blockchains. Our work covers bridge architecture, verification, relayers, monitoring and operator tooling, with a focus on security, reliability and safe cross-chain communication. Most bridge exploits target the verification and key management layers. We specify, threat model and test those first. We built hashport with Hedera and BCW Group, and run a validator in its network.
We map the chains, assets, volume and latency requirements, then define how the bridge should behave when one side goes down.
We identify what the bridge relies on for security, including validators, light clients, proofs and relayers.
We model compromised signers, chain reorgs, replayed messages and dependency outages.
We implement one real transfer across your riskiest chain pair and benchmark it early.
We deliver contracts, relayers and monitoring while continuously testing against reorgs, replayed messages and key compromise.
We prepare the specifications and evidence, then fix and retest every finding.
We open with value caps, rate limits and alerts, then raise them as the numbers hold.
