What is Forta Firewall?

Forta Firewall detects and blocks malicious transactions before execution. Firewall integrates into the transaction flow and stops malicious transactions before they are included in a block.

It can be leveraged by rollups and protocol teams to screen transactions in real-time for security and compliance risks.

For Rollups

For the case of rollups, Forta works with a rollup’s RaaS provider to route transaction activity to Firewall for screening. High-risk transactions are flagged and filtered out before they get to the sequencer.

For Protocols

For protocols, Firewall integrates at the smart contract level to require that specified transactions are accompanied by an on-chain attestation that indicates that the transaction went through automated security checks. Transactions that are flagged as high risk do not receive attestations and will revert on-chain.

Censorship-Resistance

For censorship-resistance, transactions flagged as high risk are not permanently blocked, but delayed, with details revealed only to the Firewall user and giving them time to respond.
