Private transfers on Ethereum

Context

A privacy protocol on Ethereum. Every Ethereum transfer is public, so anyone holding tokens gives away their balance and full history to whoever looks.

What we did

• Built smart contracts and zero-knowledge proofs that let people hold and send tokens privately.
• Kept everything on Ethereum itself, so users get privacy without moving to a separate network.

How it ran

Senior engineers worked inside the protocol team on the contracts and the proof system.

What changed

• On-chain privacy without a separate network: users keep Ethereum’s security and liquidity, and keep their balances to themselves.

Client names stay private. The work is real, and references are available on request.
