contracts-autofoundry

Audited smart contract primitives for agent-to-agent payments, capability gating, and streamed settlement. Built with Foundry, tested on testnets, double-audited.

Contracts

atomic-pay-for-access

Hashlock escrow that atomically settles payment and mints an on-chain access credential in a single transaction. Supports native ETH and ERC20/TIP20 tokens.

Deployed on: Base Sepolia, Tempo Moderato

Use cases: agent-to-agent payments, gated API access, pay-per-use content, bounty settlement, x402 payment flows, operator fee splitting.

Security: Double-audited (manual + Plamen autonomous audit), 51 tests passing, E2E verified on-chain.

slot-seal

Destination-scoped slot receipt primitive for routed work, parallel execution lanes, and paid delivery proofs. A slot is assigned to one assignee for one destination and can only end as completed or reclaimed.

Deployed on: Base Sepolia, Tempo Moderato

Use cases: routed agent work proofs, destination-scoped batch execution, reclaimable execution slots, x402-style delivery attestations, compact assignment lifecycle receipts.

Security: 14 unit tests passing, full intent-hash enforcement, chain-and-contract domain separation, tombstoned reclaim semantics, no admin or upgradability.
