Polkadot Agent Platform

This repository contains a greenfield implementation of an agent-first treasury and job runtime:

• Foundry contracts for account, escrow, policy, strategy registry, and reputation
• A shared service layer exposed through HTTP and directory-safe MCP discovery
• Discovery and indexing scaffolds for later hosted deployment

Launch posture and trust documents:

• Production readiness checklist
• Threat model
• No token statement
• Week-12 bootstrap gate
• Product-proof gate
• Arbitration migration
• Dispute reason-code registry
• Service token operator pack

The mcp-server workspace currently uses a JavaScript runtime source tree. There is no parallel TypeScript build step to maintain.

Development setup

After cloning, install the git hooks once so staged commits are scanned for accidentally-staged .env files and private-key-shaped strings:

./scripts/install-hooks.sh

Run the full test matrix locally:

npm test               # backend + frontend + forge

npm run typecheck:indexer

CI runs the same four jobs on every push to main and every PR via .github/workflows/ci.yml.

Multi-agent branch start

Before any agent starts new work, create its branch through the guarded helper:

./scripts/ops/start-agent-branch.sh codex/your-task-name

The helper fetches origin, switches local main to the latest origin/main, fast-forwards only, then creates the new branch. This keeps each agent from starting work on a stale local main.

Local deployment flow

1. Start a local Anvil chain:

./scripts/start_anvil.sh

1. In another terminal, deploy and configure the contract suite:

./scripts/deploy_contracts.sh

1. Export the addresses returned by the deploy script and write a server env file:

export AGENT_ACCOUNT_ADDRESS=0x...

export ESCROW_CORE_ADDRESS=0x... export REPUTATION_SBT_ADDRESS=0x... export DISCOVERY_REGISTRY_ADDRESS=0x... export TREASURY_POLICY_ADDRESS=0x... export MOCK_DOT_ADDRESS=0x... ./scripts/write_server_env.sh

1. Start the service:

cd mcp-server

set -a source .env.local set +a npm run start:http

The HTTP adapter will use live on-chain reads and signed writes whenever the env file contains a valid RPC URL, signer key, and deployed contract addresses.

The live API now also exposes a push-only SSE stream at /events behind the app proxy as /api/events.

If you want durable sessions and verifier results, also set:

REDIS_URL=redis://...

REDIS_NAMESPACE=agent-platform

Without REDIS_URL, the service falls back to in-memory state for local development.

Pimlico / ERC-4337 gas sponsorship

The hosted API can now expose a minimal Pimlico-backed gas sponsorship surface when these env vars are set:

PIMLICO_BUNDLER_URL=https://...

PIMLICO_PAYMASTER_URL=https://... PIMLICO_ENTRY_POINT=0x... PIMLICO_SPONSORSHIP_POLICY_ID=... PIMLICO_CHAIN_ID=...

Once configured, the HTTP server exposes:

• GET /gas/health
• GET /gas/capabilities
• POST /gas/quote
• POST /gas/sponsor

These endpoints are intended for ERC-4337 user operation quoting and sponsorship. They do not replace the current direct signer flow yet; they add the hosted gas-management path so the platform can evolve toward smart-account execution.

To verify Redis-backed resumability across separate runtimes:

cd mcp-server

set -a source .env.local export REDIS_URL=redis://... set +a npm run check:redis

That check creates a session in one runtime, verifies it, then loads the same session/result through a second runtime to prove persistence.

End-to-end local demo

With Anvil running and mcp-server/.env.local populated, run:

cd mcp-server

set -a source .env.local set +a npm run demo:e2e

The demo mints mock DOT, deposits into AgentAccountCore, creates a funded job, claims it as a worker, submits work, resolves escrow through the verifier role, and checks that payout plus SBT minting completed.

End-to-end remote demo

To run a real hosted-stack smoke test against the production-like API:

cd mcp-server

REMOTE_E2E_BASE_URL=https://api.averray.com \ REMOTE_E2E_PRIVATE_KEY=0xyour-test-agent-private-key \ npm run demo:e2e:remote

When REMOTE_E2E_PRIVATE_KEY is set, the script runs the full SIWE sign-in flow — POST /auth/nonce → personal_sign → POST /auth/verify — and uses the returned JWT on every protected call. Against a AUTH_MODE=permissive deployment you may instead supply only REMOTE_E2E_WALLET and skip signing.

That script:

• checks live API health
• signs in with SIWE (when a private key is provided)
• creates a unique remote job via /admin/jobs
• claims it
• submits work
• runs verification
• confirms the session appears in hosted history

Authentication

Protected routes require a signed-in JWT issued via Sign-In with Ethereum (EIP-4361). The flow:

POST /auth/nonce   { wallet }              → { nonce, message }

personal_sign(message) via wallet provider → signature POST /auth/verify { message, signature } → { token, wallet, expiresAt } POST /auth/logout (Authorization header) → revokes the token's jti

Subsequent requests pass the token as Authorization: Bearer . For SSE endpoints (/events) the token goes as ?token=... because the browser EventSource API cannot set custom headers — this is the only exception and the server logs a warning if a token is supplied via query string on any non-SSE route.

External agents should start from GET /onboarding. It now exposes:

• onboarding.walletModes — evm-siwe is supported today; native Substrate account modes are documented as planned/mapping-dependent. Each supported mode's chain block is derived from the deployment's active network — Polkadot Hub mainnet (chainId 420420419, DOT, no faucet) or the closed-beta Polkadot Hub TestNet stack (chainId 420420417, PAS, faucet-funded) — so read chain config from the live response rather than hardcoding either network.
• onboarding.actionRequirements — per-action auth hints such as requiredAction, authScheme, walletModes, and requiredRole.
• onboarding.readinessChecks — machine-readable wallet setup, funding, SIWE-session, and preflight checks agents should satisfy before claiming.
• auth.entrypoints — the canonical nonce, verify, and logout endpoints.

For the first-agent operator guide, see docs/AGENT_OPERATOR_ONBOARDING.md. For wallet-specific setup, see docs/AGENT_WALLET_ONBOARDING.md. The current protected HTTP path is an Ethereum-compatible 0x... wallet using SIWE. Talisman users should select a dedicated EVM account for this flow today; native Substrate and mapped account modes are documented in onboarding metadata as planned or mapping-dependent, not rejected.

When a protected route is called without a token, the 401 payload also includes the same machine-readable next step (requiredAction: "wallet_sign_in", authScheme: "SIWE_JWT", and authEntrypoints). Role-gated routes add requiredRole.

Logout revokes the current token by writing its jti into a TTL-bounded blacklist in the state store. Any subsequent request with that token returns 401 token_revoked. Blacklist entries auto-expire alongside the token's own exp so Redis does not grow unbounded.

Public routes (no auth required): /, /health, /metrics, /agent-tools.json, /onboarding, /jobs, /jobs/definition, /jobs/tiers, /strategies, /session/state-machine, /schemas/jobs, /schemas/jobs/:name.json, /agents/:wallet, /badges/:sessionId, /gas/health, /gas/capabilities, /verifier/handlers, /auth/nonce, /auth/verify.

AUTH_MODE=strict (production default) rejects unauthenticated requests on protected routes with 401. AUTH_MODE=permissive (dev default) falls back to the legacy ?wallet= query param and logs a warning — useful for local demos until every caller has been migrated.

Environment variables (see mcp-server/.env.example):

• AUTH_MODE — strict | permissive
• AUTH_JWT_SECRETS — comma-separated HS256 secrets. First entry signs new tokens; rest remain accepted during verification to support zero-downtime rotation. Each must be ≥32 characters.
• AUTH_DOMAIN — SIWE domain and expected verifier check.
• AUTH_CHAIN_ID — SIWE chainId and expected verifier check.
• AUTH_TOKEN_TTL_SECONDS (default 86400) — JWT lifetime.
• AUTH_NONCE_TTL_SECONDS (default 300) — SIWE nonce lifetime.
• AUTH_ADMIN_WALLETS — comma-separated EVM addresses granted the admin role claim at sign-in. Required to call POST /admin/jobs.
• AUTH_VERIFIER_WALLETS — comma-separated EVM addresses granted the verifier role claim at sign-in. Required to call POST /verifier/run.

Roles are pinned at sign-in time by env config; a user picks up role claims when they SIWE-login, so rotating the env lists invalidates authority at the next sign-in rather than on every request. Each protected route that needs a role checks the JWT claim and returns 403 missing_role on a mismatch. On-chain escrow resolution is additionally gated by TreasuryPolicy.verifiers; in the current backend-signer architecture, the configured chain signer is the authorized verifier address.

External agents should start with docs/EXTERNAL_AGENT_WALLET_ONBOARDING.md. That guide explains what can be inspected without a wallet, what requires a wallet, and how a browser-supervised or self-hosted agent should obtain and use a dedicated agent wallet without exposing private keys to the model (its worked examples target the closed-beta testnet stack).

Key rotation: prepend the new secret to AUTH_JWT_SECRETS, redeploy, then drop the old secret after AUTH_TOKEN_TTL_SECONDS has elapsed so that every token issued under the old key has expired.

Builder SDK

A small ESM client lives at sdk/agent-platform-client.js. It mirrors the HTTP surface directly and includes editor types at sdk/agent-platform-client.d.ts.

import { AgentPlatformClient } from "./sdk/agent-platform-client.js";

const client = new AgentPlatformClient({ baseUrl: "https://api.averray.com" });

const manifest = await client.getDiscoveryManifest(); const schemas = await client.listJobSchemas(); const lifecycle = await client.getSessionStateMachine(); const profile = await client.getAgentProfile("0xFd2EAE2043243fDdD2721C0b42aF1b8284Fd6519");

Authenticated flows reuse the same client after SIWE verification:

client.setToken(token);

const account = await client.getAccountSummary(); const recommendations = await client.getRecommendations(); const catalog = await client.listClaimableJobs({ limit: 100 }); const jobs = Array.isArray(catalog) ? catalog : catalog.jobs; const selected = jobs.find((job) => ( job.claimable === true && job.onboardingWaiverEligible === true )); if (!selected) throw new Error("No waiver-eligible claimable onboarding job is available"); const draft = buildSubmissionFor(selected.outputSchemaRef); const validation = await client.validateJobSubmission(selected.id, draft); if (!validation.valid) throw new Error(validation.message); const claim = await client.claimJob(selected.id, "onboarding-claim-001");
