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. This release's build is fullscale-rc31 (buildId ec80d60, image sha256:cae6b7e7cb073a17b7f9dc0dd54288556e13c6157f08a1712e91624e0878fc32); the served /api/v1/health buildId is authoritative for which build is active at any moment (ec80d60 = this release; 9dbc5f7 = the preceding rc30 build of this same source line, live since 2026-09-09 06:01 UTC). You can also fully self-host
Current production source	PUBLIC — this repository, v1.9.3 (exact identity chain in PUBLIC_RELEASE_MANIFEST.md; v1.9.2 and v1.9.1 remain published unchanged; the prepared candidates v1.6.0 / v1.7.0 / v1.8.0 / v1.9.0 were never published separately and are included)
Organizational M-of-N owner root (covenant v0.7)	COVENANT-BYTE-FROZEN (2026-09-03) · VM-verified · SDK/production-byte-verified · testnet-verified · application surface LIVE in the hosted deployment but TESTNET-ONLY — v0.7 roots cannot be created on mainnet (GENERATION_NOT_MAINNET_AUTHORIZED); the mainnet-creatable generation is policyvault-0.4.1 only
Rooted-vault owner operations in the browser (R7-05) + reservation/withdrawal guidance (F-6)	LIVE in this source (testnet-only surface) — headless-Chromium evidence on the exact image with a TEST-ONLY dev signer; no real-wallet or human evidence is claimed
Hosted tenancy for every route family + generation gate (rc11 remediation)	LIVE — closes the rc8 findings (unauthenticated hosted builds, prototype-derived version selection, unsafe mainnet creation of the non-standard v0.4 generation)
Post-launch live-stack review corrections (rc29: webhook target policy + DNS transport, SDK transport recovery key, legacy same-effect completion ownership, image/package LICENSE + NOTICE, privacy-safe runtime artifacts, recovery guidance)	IN THIS SOURCE and in the fullscale-rc29 image — every finding of the independent read-only review of the running rc28 stack corrected RED-first with a permanent regression; the hosted deployment carries them once the served buildId reads f217011; installed SDK / mobile clients must upgrade for the transport correction
Second post-launch review corrections (rc30: webhook response-socket lifetime bound; upstream Silverscript ISC notice beside the compiler and the reference program)	IN THIS SOURCE and in the fullscale-rc30 image — both findings of the independent read-only launch review of the running rc29 stack corrected RED-first with a permanent real-socket regression; the hosted deployment carries them once the served buildId reads 9dbc5f7; no SDK / mobile client byte changed
Organization UI availability correction (rc31: organizational-root creation offered only where capability discovery advertises it; generation refusals say that address/amount changes cannot enable an unsupported mainnet generation; build errors scoped to the wizard)	IN THIS SOURCE and in the fullscale-rc31 image — the owner-observed RC30 finding, corrected RED-first with a 13-case DOM regression that drives the real page and scripts (synthetic wallet, intercepted HTTP); browser presentation only — the server / SDK generation gates are unchanged and remain the authority; no SDK / mobile client byte changed
MCP package (policyvault-mcp on npm)	1.5.0 published (2026-09-09; registry tarball byte-identical to the audited artifact) and proven against the live API (real stdio initialize, 19-tool catalog with an all-scope credential, least-privilege 2-tool discovery with read:network); unchanged by this release — no republish
Flagship wave 1 (v1.6.0 / v1.7.0) and wave 2 (v1.8.0) source	INCLUDED and LIVE where applicable (see their CHANGELOG entries; v0.6 stays FIXTURE VENUE ONLY / no mainnet swap; x402 facilitator PRODUCTION-READY, NOT deployed; MCP usage telemetry OFF)
Covenant protocol v0.6 (atomic composability)	COVENANT-BYTE-FROZEN (2026-09-03): VM-verified on the real engine with production bytes and testnet-verified (live testnet-10 SELL + BUY). FIXTURE VENUE ONLY — no real DEX venue, no mainnet swap, no server/web/mobile/MCP surface, deadlineDaa is a pre-sign boundary and not a consensus expiry, and swaps are not economically viable below roughly 10 KAS. PolicyVault is not a DEX and will not become one. See docs/postlaunch/v0.6-covenant-byte-freeze.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
Security assurance	INTERNAL and evidence-based only: independent internal AI falsification reviews of each exact candidate (the reviewer never repairs its own candidate), hostile / adversarial testing on the real Kaspa script engine with production bytes, RED-first reproduction with permanent regressions, production-shaped mechanical verification, live testnet-10 evidence, exact artifact and frozen-byte verification, and the owner's own live mainnet validation after each deployment. No external professional security audit has occurred and none is part of PolicyVault's process (owner policy, 2026-09-05); nothing in this repository claims otherwise

• x402 FACILITATOR (integrations/x402-facilitator/, 2026-09-02): DESIGN FROZEN (owner-authorized; docs/postlaunch/x402-facilitator-design-freeze.md) · IMPLEMENTED · UNIT-TESTED · ADVERSARIAL-TESTED · INTEGRATION-TESTED (real HTTP service + real PostgreSQL claim store) · TESTNET-VERIFIED (real KAS + real frozen-v0.5 token payments on testnet-10; docs/testnet-x402-facilitator-evidence.json). A separately deployed, unprivileged, READ-ONLY chain verification / settlement attestation service for the proposed Kaspa scheme pv-x402-kaspa-exact-upfront/1 (network identifiers kaspa:mainnet / kaspa:testnet-10 are PolicyVault's provisional CAIP-2-syntax identifiers — no upstream registration is claimed). It never signs, broadcasts, escrows, or charges. NOT a hosted production service (a separate owner gate); no upstream Kaspa x402 scheme exists, so it is not "x402-compatible" without that qualification.

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)

# prerequisites: Node 20.x; a local Kaspa testnet-10 node with --utxoindex
#   (rusty-kaspa; JSON wRPC on ws://127.0.0.1:18210)
cd sdk && npm ci && npm test          # the SDK suite (serialized)
cd ../server && node src/server.js    # self-hosted mode, JSON persistence
# open http://127.0.0.1:3080 — connect a testnet KasWare wallet

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).
