MPC

Local Rust implementation of the MPC HTTP API.

This is a local demo, not production threshold custody.

Workspace

• types: shared wire types, ciphertext envelopes, fixed-byte serde, and API DTOs.
• codec: canonical CBOR AAD encoding/decoding and typed plaintext encoding.
• crypto: HPKE, AES-GCM, Keccak helpers, keypair ownership, and ciphertext transforms.
• service: MPC service state, local attestation policy, Axum API, and binary runtime.

Future coordinator, coprocessor, or client work should depend on the shared crates directly when it needs wire types, byte codecs, or crypto fixtures.

Run

cargo run -p mpc

The service binds to 127.0.0.1:3000 by default. Override with:

MPC_BIND_ADDR=127.0.0.1:3001 cargo run -p mpc

Test

cargo test --workspace
