Polygon security review
Polygon is a family of Ethereum scaling products: the proof-of-stake chain, zero-knowledge rollups, and the bridges that connect them to Ethereum. Hackerbane audits the contracts you deploy on each and the messages you treat as final.
What we review
A proof-of-stake checkpoint and a zero-knowledge validity proof carry different guarantees. Every Hackerbane engagement names the Polygon stack in scope, so finality, delay, and bridge findings are correct for the chain you run.
- Solidity contracts on the Polygon chain you deploy to.
- Deposit and exit paths to Ethereum.
- Checkpoint and proof timing, and the withdrawal delay you rely on.
- Off-chain services that sign on Polygon and treat the result as settled on Ethereum.
One audit, the right stack
PoS, zkEVM, and CDK chains share Solidity and differ in everything underneath. We scope for the stack you use and, when you run more than one, cover the bridge between them.
