Documentation Overview
PolicyVault
Non-custodial delegated-spending vaults on Kaspa L1 — for people and AI agents.
PolicyVault lets a vault owner hand a spending key to an agent — an employee, a service, a bot, or an AI agent — without handing over control of the funds. The spending policy is enforced by Kaspa L1 consensus through a covenant: even an agent who bypasses this entire application and talks directly to a Kaspa node cannot exceed the owner's policy.
The authority model, stated once and everywhere enforced:
AI MAY REQUEST. POLICYVAULT DETERMINISTICALLY DECIDES. THE COVENANT ENFORCES. SIGNERS RETAIN CUSTODY.
Production status (honest labels)
| Surface | Status |
|---|---|
| Web / Agent platform | PRODUCTION — LIVE at https://app.policy-vault.org (hosted deployment of this source; you can also fully self-host) |
| Current production source | PUBLIC — this repository (buildId 1c02162; exact identity chain in PUBLIC_RELEASE_MANIFEST.md) |
| v0.5 token-controller covenant (byte-frozen) + least-privilege discovery / console correctives + MCP 1.4.2 (v1.5.0) | LIVE — production runtime successor fullscale-rc8 (buildId 1c02162) deployed and automated-accepted on 2026-09-02: principal-scoped capability discovery, no dev-signer probe on production, zero privileged reads while signed out, opt-in wallet diagnostics; policyvault-mcp@1.4.2 advertises only the tools a credential's scopes cover (server-side enforcement unchanged). The v0.5 TOKEN CONTROLLER covenant (contracts/PolicyVault.v0.5.sil, sha256 c693aeff…) ships as SOURCE — COVENANT-BYTE-FROZEN, VM-verified with production bytes and testnet-verified with one live lifecycle; NOT production (no v0.5 surface, no mainnet v0.5 vault). Illustrated onboarding walkthrough (presentation only). See CHANGELOG |
| Distribution: MCP registry, agent examples, self-hosting (v1.4.0) | Source/distribution release — NO runtime change (production keeps buildId 6c3177f): the MCP server is npm/registry-packaged (policyvault-mcp, io.github.zapsoblige-hash/policyvault), thin OpenAI-Agents-SDK/LangChain/CrewAI wiring examples ship in examples/agents/, and one-command self-hosting ships in deploy/selfhost.sh + docs/selfhost-quickstart.md; see CHANGELOG |
| Bearer wallet-sessions + native mobile transport (v1.3.0) | LIVE: opt-in bearer wallet-session authentication for non-browser clients (authentication only — never signing authority or custody; cookie web auth unchanged), plus the native Android transport (explicit CapacitorHttp at the platform seam; no CORS widening, web client stays strict same-origin). The full bearer lifecycle was proven from the real packaged Android runtime against live production; see CHANGELOG |
| Responsive client + quiet signed-out UX (v1.2.0) | Faster signed-in navigation (retained state, parallel reads, truthful progress states — pending is never success) and no spurious signed-out error toasts; see CHANGELOG |
| Network-identity banner fix (v1.1.1) | The web client's network banner now derives from the server's node-verified /network/status and FAILS CLOSED to an explicit UNKNOWN state — never a stale or assumed network; see CHANGELOG |
| In-app documentation discovery (v1.1.0) | Docs link + contextual help in the web client, deep-linking to https://docs.policy-vault.org — presentation-only successor; see CHANGELOG |
| External-approver discovery fix (2026-08-27) | DEPLOYED + AUTOMATED-ACCEPTED (fail-closed availability defect, no funds/authority/privacy exposure; see CHANGELOG "Fixed". Acceptance was automated; no human acceptance test is claimed) |
| Covenant protocol v0.4.1 | Mainnet-operational (real mainnet lifecycle evidence; see SECURITY.md for exactly what is proven and how) |
| Covenant protocol v0.5 (token controller) | COVENANT-BYTE-FROZEN (2026-09-02): VM-verified on the real engine with production bytes and testnet-verified (live testnet-10 lifecycle, consensus-rejected negatives); not production — no server/API/web surface, no mainnet instance; see docs/postlaunch/v0.5-covenant-byte-freeze.md |
| Python client, MCP server, x402/AP2 adapters, platform agent API | Shipped; covered by the automated conformance/integration suites in this repository |
| Native mobile (iOS/Android) | DEVELOPMENT — NOT YET PRODUCTION-CAPABLE. The Android app (full Capacitor project in mobile/, incl. the native production transport and bearer sign-in) has been validated on a real emulator against live production — reads, full bearer auth lifecycle, fail-closed negatives — but production signing, store packaging, and camera/QR capture remain pending; do not build custody workflows on it yet |
| External professional security audit | Has NOT occurred. Planned. Nothing in this repository claims otherwise |
What the covenant enforces (consensus, not software)
- Owner-controlled vaults — create, manage, pause, recover, close.
- Delegated spending — up to 10 independent agents per vault, each with its own policy, spending real KAS within owner-defined limits.
- Per-transaction caps and cumulative periodic budgets (DAA-score-based accounting verified by consensus).
- Recipient allowlists — Merkle-committed; an agent can pay only owner-approved recipients.
- M-of-N approvals above an owner-set threshold.
- Covenant-controlled fee reserve — agents need no gas wallet; network fees come from a reserve the covenant accounts for exactly.
- Break-glass owner pause and terminal recovery — never gated by any hosted workflow.
What the platform adds ABOVE the covenant (hosted coordination, not authority)
- Intent manifests + independent browser verification — before any
signature, the browser re-derives what the transaction does from the exact
bytes to be signed and refuses on any mismatch (
web/verify-intent.js,docs/postlaunch/intent-manifest-spec.md,docs/postlaunch/browser-verification.md). - Governance — proposal/approval ceremony (Schnorr-verified,
domain-separated) for authority-expanding policy changes
(
docs/postlaunch/governance-spec.md). - Risk pipeline — restrictive-only configurable review/deny adapters
(
docs/postlaunch/risk-adapter-spec.md). - Budget reservations, hash-chained audit, webhooks/notifications,
machine identities + scoped capabilities, idempotency, dry-run simulation
(
docs/postlaunch/*). - Universal Signer Interface with KasWare mapping and an offline CLI
signer reference (
docs/postlaunch/signer-interface-spec.md,signer-kasware-mapping.md,signer-cli-reference.md). - Agent surfaces: REST platform API, MCP server, Python client, x402 + AP2 payment-protocol adapters — all thin consumers of one deterministic core; none holds independent financial authority.
None of this hosted machinery can move funds: every funds-moving signature is made by the owner's or agent's own wallet over frozen bytes, and Kaspa consensus checks the covenant regardless of what any server says.

Quick start (self-hosted, testnet-10)
Full instructions, including PostgreSQL-backed hosted mode, container builds,
covenant regeneration + byte-identity verification, and the VM suite:
docs/deployment.md, docs/hosted-deployment.md, docs/test-plan.md.
The VM workspace expects sibling checkouts of the public silverscript and
rusty-kaspa projects (see tests/vm/ and tools/stage-vendor.sh).
