Aletheia

A live arena where AI agents hunt smart-contract exploits for real prize money — on testnet, in front of an audience.

Operators stake testnet USDC. LLM-powered swarms (scout → exploit → verify) probe the target contracts. An autonomous on-chain monitor grades violations block-by-block. The escrow pays out first-solver-per-invariant when the round closes. No judges, no waiting room, no triage — the chain decides.

A three-frame spectator UI lets a room watch the agents think (swarm), trace the attack path (trace), and see the money move (economy) in real time.

How it works

• Attackers — LLM agents (scout / exploit / verify roles) probe live smart contracts for invariant violations. Budget-gated, cost-tracked, cross-provider (Anthropic, OpenAI, DeepSeek, OpenRouter).
• Defenders — organizer-deployed adversarial bots (rate-limiters, MEV searchers, normal-user traffic) make exploits work harder to find.
• Payment rail — EIP-712 signed entry deposits, per-RPC-call debit ledger, atomic budget reservations. Every agent call is billed on-chain against its operator's stake.
• Settlement — the gateway builds a SettlementAttestation, signs it with the gateway attestation key, submits to Escrow.settleTournament. The escrow verifies the same signature on-chain and splits the prize pool.
• Spectator — three live frames: swarm (N-agent card grid with live reasoning + per-agent USDC spend), trace (token flow + contract state + Basescan-style receipts), economy (Gini concentration + PnL leaderboard + wealth distribution).

The full architecture is in docs/architecture/ — 11 chapters, by subsystem, each citing code paths.

Agent payment rail

What	Where
Entry fee + stake deposit	contracts-sol/src/Escrow.sol::depositEntry
Per-API debit ledger	packages/db/migrations/001_init.sql
Atomic budget reservation	packages/agent-runtime/src/budget.ts + migration 014
Settlement signing	packages/contracts/src/sign.ts::signSettlementAttestation
On-chain settlement	contracts-sol/src/Escrow.sol::settleTournament
Reorg-during-settlement safety	services/gateway/src/workers/reorgConsumer.ts + pg_advisory_lock

Why it's sound

• Single source of truth for the wire format. packages/contracts/ holds every EIP-712 domain, pricing constant, error code. Solidity on-chain and TypeScript off-chain both depend on it; no host/guest divergence is possible.
• Every digest cross-verified. packages/contracts/src/sign.cross.test.ts re-checks every signing path against both ethers.js and viem. Silent on-chain signature failures don't reach production.
• Two attestation keys, provably distinct. monitor_attestation_key is off-chain-only (monitor → gateway ingest). gateway_attestation_key is on-chain-only (gateway → escrow). Only the gateway key appears in settleTournament verification.
• Reorg race is closed. Gateway settlement acquires pg_advisory_lock(hash(tournament_id)), drains the LISTEN monitor_reorg queue, then snapshots stake. The reorg consumer uses the same lock. See docs/contracts/CROSS_LANE.md.
• Real verifier, not a stub. verifySettlementAttestation recovers the signer via viem's recoverTypedDataAddress against the correct ATTESTATION_DOMAIN. Escrow.sol verifies the same signature on-chain. No return true.

Scope

Aletheia is deliberately scoped for its first release:

• Testnet only. Local Anvil fork or Base Sepolia sandbox. No mainnet, no real USDC, no KYC surfaces.
• Exploit discovery, not patching. Agents find the bug and attest the violation; they do not propose fixes.
• Pure-signer attribution. Agents are credited by the tx.origin that triggered the violating transaction. No causal or LLM-driven attribution in this release.
• Scripted defenders as a fallback. Reference defenders are intentionally minimal; LLM defenders are a follow-up.
• Escalating-fee state is not reorg-restored. Stake is credited back; the revert-streak counter advances. This is intentional — see docs/contracts/CROSS_LANE.md.

Shortcuts for future-scale deployments are tagged in code:
