About

Protofire is a blockchain engineering firm that began as a blockchain spin-off of the software company Altoros and designs, builds and operates onchain systems for Web3 protocols, DeFi platforms and financial institutions. Its smart contract development covers Solidity, Vyper, Rust and Plutus or Aiken code for Ethereum and other EVM networks, Solana and Cardano, including token standards, oracles, upgradeability, governance, frontends and subgraphs. Protofire also sells smart contract audits: static analysis and linting, threat modelling of oracle, flash-loan and liquidation risks, manual line-by-line and system-level review, infrastructure review, then remediation and re-audit by the same engineers. It offers pre-audit hardening to reduce the findings of an external audit, QA and fuzz testing with Hardhat, Foundry and Echidna, incident response and managed onchain operations. Completed audit reports are published on its website. The firm maintains Solhint, the open-source Solidity linter, and also provides node infrastructure, indexing, staking and tokenization work for DeFi, RWA and institutional projects.
