Protofire is one of the earliest blockchain engineering firms, building and operating production Web3 systems since 2016. We maintain Solhint, an open-source Solidity linter and security tool used by over a million developers, and we build within the Chainlink, Safe, The Graph, and Blockscout ecosystems.

We are a full-stack blockchain engineering partner. Our teams design, ship, and operate:

Smart contracts and security: Solidity development, protocol engineering, audits, and static analysis with Solhint.
On-chain finance: lending and borrowing, staking and yield vaults, stablecoin systems, and tokenized real-world assets (RWA), built on standards such as ERC-4626 and ERC-3643.
Cross-chain and oracles: Chainlink oracle feeds and CCIP integrations, and cross-chain messaging.
Data and indexing: subgraphs and indexing on The Graph.
Infrastructure we run in production: nodes, block explorers (Blockscout), and Safe multisig and custody, on cloud and bare metal, for networks with heavy usage and non-EVM functionality, including UTXO and multi-sharding models.
For banks, fintechs, exchanges, and asset managers, we build the on-chain products they launch under their own brand: embedded earn and yield, crypto-backed lending, own-brand vaults, tokenized treasuries, and stablecoin payment rails, delivered and run as managed on-chain operations.

Selected work spans Chainlink, Safe, The Graph, Blockscout, Filecoin (glif), Harmony, DIA, Quai, Vana, Swarm, and Telos. Across multiple market cycles since 2016, Protofire has delivered 250+ projects for 60+ networks and 95+ protocols, secured $2B+ in on-chain assets across 120+ networks with zero vulnerabilities across delivered projects, and is trusted by teams including Aave, Balancer, Sky, and CoW Protocol.
