About Chainsafe

Chainsafe builds infrastructure for Ethereum and other decentralized networks, including clients, SDKs, and tools to support dApps, gaming, and cross-chain bridging.

ChainSafe is a pioneering blockchain R&D firm specializing in cross-chain interoperability, Web3 gaming infrastructure, and advanced protocol engineering. Headquartered in Canada and working globally, the company is dedicated to shaping the future of decentralized systems through its contributions to both private development and public goods. ChainSafe supports projects at every layer of the stack—from smart contract audits to fully-fledged protocol implementations.


Built with open-source principles and a multi-chain approach, ChainSafe offers a wide range of products and services that empower developers, enterprises, and ecosystems alike. Whether through their production-ready tools for Ethereum, Polkadot, Filecoin, or their native Web3 gaming suite, ChainSafe is helping lead the charge into a more interoperable, inclusive, and resilient blockchain future.

ChainSafe is a full-spectrum blockchain research and development company that bridges the gap between protocol-level infrastructure and consumer-facing Web3 applications. Founded with a mission to ensure that future digital systems run on decentralized infrastructure, ChainSafe has contributed significantly to the evolution of blockchain standards and cross-ecosystem compatibility. By leveraging its talented global engineering teams, ChainSafe offers tailored solutions for clients that demand both performance and security.


ChainSafe's product suite is purpose-built for real-world blockchain challenges. The Gaming SDK allows developers to create in-game marketplaces, mint NFTs, and manage wallets—all within an integrated platform for Web3 games. Their ChainSafe Files system delivers secure, decentralized file storage through the Filecoin network, using end-to-end encryption and zero-knowledge architecture. For developers requiring modular integration, the Storage product makes adding decentralized storage to apps as easy as deploying an API.


On the public goods side, ChainSafe is deeply involved in maintaining and developing critical components for major ecosystems. Lodestar is a TypeScript-based Ethereum consensus client; Gossamer is a Go implementation of Polkadot; Forest supports Filecoin with a Rust-based node. Additionally, ChainSafe maintains web3.js, the most widely used JavaScript library for interacting with Ethereum, further anchoring their influence in the Web3 space.


ChainSafe has also gained the trust of major partners and clients like Ethereum Foundation, Web3 Foundation, The Graph, Push Protocol, Moonbeam, and Protocol Labs. Their portfolio spans across engineering, auditing, protocol development, and consulting—cementing them as a cornerstone in the Web3 space.


In a growing ecosystem of infrastructure firms, ChainSafe stands alongside prominent players like ConsenSys, Parity Technologies, IOHK, and Protocol Labs. However, their unique focus on open-source development and multi-chain R&D makes ChainSafe a distinctly valuable contributor to Web3's foundational future.
