Overview
ChainSafe Systems was formed in Toronto in early 2017 by founders who met at the city’s Ethereum developers meetup; it began with consulting work before moving into protocol engineering.[3] Its projects include Lodestar, a TypeScript implementation of the Ethereum consensus layer that received an early grant from Vitalik Buterin; Gossamer, a Go implementation of the Polkadot runtime environment; and Forest, a Rust Filecoin client funded by Protocol Labs grants. The company also took over maintenance of the web3.js library and acquired the Croatian firm NodeFactory.[3] In 2022 it closed a CA$25.7 million Series A led by Round13 Capital’s Digital Asset Fund, and at the time reported more than 120 employees.[4] The company’s history post from May 2022 gives a similar figure of 115-plus people.[3]
ChainSafe Systems strengths and limitations
Strengths

- Maintains widely used open-source libraries
Limitations
- Most recent published headcount dates from 2022
- Grant-funded protocol work is a large part of its profile, so commercial app capacity is harder to gauge
