# Protofire > Custom Web3 and blockchain development agency. Since 2016, Protofire has built smart contracts, DeFi protocols, tokenization/RWA infrastructure, oracles, indexers, and node infrastructure for 60+ networks and 95+ protocols, and increasingly for institutional and specialty-finance clients moving on-chain. ## About Protofire is a blockchain development company, founded in 2016 as a spin-off of Altoros. We act as an embedded engineering team for Web3 projects, L1/L2 chains, DeFi protocols, and, as real-world assets move on-chain, for financial institutions, asset managers, treasuries, and specialty-finance originators. We build bespoke infrastructure; clients own the contracts. ## What we do (services) - Blockchain Consulting, engineering-led architecture, chain selection, tokenomics, security, and infrastructure strategy, with the team to build what we recommend -
