# pacta — proof-aware crypto tooling agent

## Start here
|
|
|
|
|
|
|
|
|
|
|
|
- [README.md](README.md): what pacta is, the R0–R5 risk model, the dogfood loop.
|
|
|
|
|
|
- [WALLET.md](WALLET.md): warden, the verified-custody wallet — the quorum boundary, the signing firewall, the R4 gate, the MCP surface.
|
|
|
|
|
|
- [docs/agent-native.md](docs/agent-native.md): why the wallet is agent-native first (AX, MCP, A2A, AP2, x402, ERC-8004) and what each idea became.
|
|
|
|
|
|
- [docs/products.md](docs/products.md): the four warden deployment profiles.
|
|
|
|
|
|
|
|
|
|
|
|
## Live evidence
|
|
|
|
|
|
|
|
|
|
|
|
- Transparency log (RFC 9162): https://ltl.zkdefi.org — signed replay attestations of the Lean proofs, one leaf per fork.

## For agents
|
|
|
|
|
|
|
|
|
|
|
|
warden speaks MCP over stdio: `pacta wallet mcp --wallet <dir>`. Tools:
|
|
|
|
|
|
`wallet_status`, `verify_inbound`, `request_signature`, `custody_card`,
|
|
|
|
|
|
`posture_challenge`, `list_incidents`, `explain_refusal`. Errors are
|
|
|
|
|
|
structured objects (code / missing / remediation). The custody card at
|
|
|
|
|
|
`.well-known/custody-card.json` is self-proving: it embeds transparency-log
|
|
|
|
|
|
inclusion proofs a counterparty recomputes rather than trusts.
|
|
|
|
|
|
|
|
|
|
|
|
## Honesty boundary
|
|
|
|
|
|
|
|
|
|
|
|
Verification paths are certificate-covered; signing is trusted base (the
|
|
|
|
|
|
attested artifact, fenced by the firewall). SHA-512 is an opaque oracle;
|
|
|
|
|
|
wire parsers are hypotheses; reproducible builds and side channels are R5,
|
|
|
|
|
|
not claimed; ML-DSA (PQC) fails closed — no proven implementation exists.
