Optimism security review
Optimism is an Ethereum layer-2 rollup built on the OP Stack, the shared codebase behind the Superchain. Hackerbane audits your OP Stack contracts and the deposit and withdrawal paths that move value to and from Ethereum.
What we review
Most application bugs on Optimism are still Solidity bugs. The chain-specific ones live in the bridge, the sequencer you trust in the short term, and the fault-proof window. A delay copied from Ethereum mainnet rarely means the same thing here, and we test each one.
- Layer-2 contracts and their admin keys.
- Deposit and withdrawal messages.
- Custom OP Stack forks, including changes to the virtual machine or the proof.
- Services that sign on layer 2 and treat the result as final on Ethereum.
For OP Stack builders
Teams launching their own OP Stack chain get one scope that covers the modified stack, the bridge contracts, and the application layer, so the report reads as one system.
