CosmWasm IBC Bridge Security Assessment

We analyze the core message handling, packet lifecycle (send, receive, ack, timeout), and state machine logic for correctness, ensuring atomicity and preventing double-spends or frozen funds.

In-depth review of your smart contracts for common CW vulnerabilities: reentrancy, unchecked user inputs, improper access control, and gas optimization for IBC packet callbacks.

Verification of channel handshake logic, counterparty verification, and connection parameters to prevent man-in-the-middle attacks and ensure only authorized chains can communicate.

Audit of incentive structures, fee distribution, and slashing conditions to ensure relayers are properly motivated and penalized, securing the network's liveness.

Assessment of migration plans, admin key management, and DAO governance proposals for contract upgrades, preventing unauthorized changes or protocol takeover.

Review of interactions with oracles, price feeds, and other external modules (e.g., ICS-20 token transfers) to identify integration risks and oracle manipulation vectors.

Our auditors are certified in Cosmos SDK and IBC protocol internals. We test for channel hijacking, packet forgery, and light client verification flaws that generic auditors overlook.

We rigorously audit the logic for verifying state proofs from counterparty chains. This prevents the #1 cause of bridge hacks: accepting invalid proofs of deposits or withdrawals.

We identify risks in contract migration, privileged execution, and inter-contract calls within the CosmWasm VM that can compromise bridge security and fund custody.

Audit the economic security of your relayer network and slashing conditions. Ensure relayers are properly incentivized and penalized to maintain liveness and correctness.

Evaluate the security of contract and chain upgrade pathways. Prevent governance attacks that could alter bridge parameters or steal locked assets in multisigs.
