Apps on c402

Built on the protocol

Each app is a c402 server (a confidential endpoint) and its clients. Same two headers, same attestation and verification - entirely different computations. All live on Ethereum Sepolia, no mock data.

Confidential Treasury

xCAT · first app

An autonomous treasury for Safe. A Market Agent buys a confidential decision over c402; a Treasury Agent decrypts it and executes a swap through unmodified Safe + Uniswap. Amounts, policy and reasoning stay encrypted; every decision leaves a public commitment.

Confidential Payroll

second app

Approve / defer / reject a raise against an encrypted remaining budget and an encrypted policy cap - the manager, the server host and the chain never see the numbers. A genuinely different computation on the exact same protocol surface.

Build your own

A c402 app is a server with one c402({…}) endpoint and clients that call it with c402Fetch. See examples/hello-c402 - a full server + client - and the protocol page.
