Introduction

PrivChain is building privacy infrastructure for machine commerce.

The protocol focus is explicit:

1. Reuse x402 for HTTP payment semantics.
2. Provide privacy-preserving verification and settlement as the differentiator.
3. Expose developer tooling (SDK + MCP-compatible surfaces) for agent-native adoption.

Current Stage

PrivChain is pre-release and actively under development.

• Token mint exists on Solana with fixed supply controls.
• Core privacy protocol and facilitator stack are in staged implementation.
• Public docs intentionally avoid sensitive implementation details.

Mission Alignment

PrivChain does not compete with x402 transport. PrivChain adds a privacy layer for x402 payment flows.
