Firewall

Firewall builds safe blockspace for smart contract networks, using mathematical methods to programmatically classify and eliminate theft as an invalid action. The platform addresses the fundamental vulnerability in blockchain networks where malicious transactions meet the weak threshold of cryptographic signature verification and sufficient balance for fees, and are therefore accepted. Firewall's safe blockspace adds a third validation criterion: analysis of a transaction's intent before finalization to determine whether it steals user assets. The system features three core components: theft classification through mathematical analysis, embedded chain-level protection, and preservation of user rights through anchoring to Ethereum. The mechanisms are non-custodial, ensuring that user rights are maintained. Founded in 2023 and headquartered in San Francisco, California, Firewall has raised $3.7 million in seed funding from North Island Ventures, Breyer Capital, and Hack VC. The company has demonstrated its Safe Sequencer technology through public proof-of-tech demonstrations, including recreating the $65 million Kyber exploit attack against Base and its testnet. Firewall advocates for a grassroots movement demanding safe blockspace, positioning itself as the evolution of smart contract networks where user safety is prioritized.
