Deep in DeFi.
Building with Stake DAO.
We help build and operate the protocol, from onchain infrastructure to the tools people use every day.
- Onchain
- Contracts and cross-chain infrastructure
- Offchain
- Indexers, internal tools, interfaces, and docs
We design, build, and operate web applications, AI agents, smart contracts, data systems, and internal tools.
Mutative is a software studio in Paris. We build our own products and help teams build theirs.
