We build, secure, and fund verifiable systems for finance & AI.
The systems that move assets and run agents can't just be trusted — they have to be provable. We take these systems from architecture to production, and fund the teams building what's next.
Get in touch →Engineering
The engineering firm. We build and secure verifiable systems—including blockchains—and run them in production.
Explore Engineering →Ventures
The venture fund. Equilibrium Ventures (EQV) backs early-stage founders across DeFi, Crypto × AI, and infrastructure—with technical diligence from our engineers.

Billions of dollars depend on the systems we've built.
What teams come to us for.
01
From prototype to production.
We prove new technical ideas in working prototypes, then take them through production and, where needed, long-term operation.
02
Patterns proven across ecosystems.
We’ve built and tested systems across Ethereum, Solana, Canton, and the XRP Ledger—first-hand experience with how different architectures behave in production.
03
Frontier agentic engineering.
AI is rewriting how software gets built, tested, and shipped. We work at the forefront of agentic engineering and bring those workflows into the teams we work with.
Selected work.
Pathfinder
A full node for Starknet, a ZK rollup on Ethereum — a safe, independent view of the network. Live on mainnet.
EUROe
Smart contracts and onchain infrastructure for EUROe, a full-reserve euro stablecoin—incubated by Equilibrium and acquired by Paxos.
SnarkOS & SnarkVM
Core client and virtual machine for Aleo, a privacy L1—spanning P2P networking, zkVM optimization, and Narwhal-Bullshark consensus.
Tesseract
Custody migration from Copper to Fireblocks under a year-end MiCA deadline, without rewriting the backend.
State Reconstruction
Full reconstruction of the ZKsync chain from only the data published on Ethereum.
Zenith
The EVM layer of Canton, a privacy-enabled institutional network. Incubated by Equilibrium.
In their words.
The Equilibrium team has done an exceptional job in developing Pathfinder, a high-performance full node implementation for Starknet. Their expertise in Rust and commitment to innovation has significantly advanced the scalability and reliability of the network.
The Equilibrium team has worked diligently with our engineering team to architect complex solutions and bring them to production launch.
The Equilibrium team behind Rust-IPFS is making great progress and adding significant improvements to the IPFS ecosystem.
