Use cases
Agent-to-Agent Task Marketplaces
Enable autonomous agents to hire and pay each other for services using conditional escrow, with funds released only when task milestones are verifiably met.
API Metering and Pay-Per-Use Billing
Lock funds upfront and release them incrementally as agents consume APIs, providing guaranteed payment for providers and usage-based settlement for consumers.
Automated Procurement Workflows
Let agents purchase goods or services on behalf of users with built-in escrow, milestone releases, and dispute primitives to reduce counterparty risk.
Verifiable Settlement for AI Commerce
Provide on-chain auditable records of agent transactions, useful for compliance, accounting, and resolving disputes in human-to-agent commerce.

Skeptical, then convinced
I went in skeptical — most tools in this space overpromise. It actually delivers on dispute resolution primitives, and programmable release conditions caught me off guard. still, I'd recommend giving it a real trial.
Use it every day
Honestly didn't expect to like it this much. Developer SDK and APIs is exactly what I needed, and purpose-built for AI agent transactions. but I reach for it almost every day now and it just clicks.

Q&A
Is it really trustless?
Yes. Neither ClearPact nor any other party holds an admin key on the ClearPactJob or ClearPactEvaluator contracts. The contracts are non-upgradeable and all roles were permanently renounced at deployment, so no one — including ClearPact — can freeze funds, decide outcomes, or push upgrades after the fact.
Asked by Dovid Klein · Aug 11, 2025
Which chains are supported?
ClearPact is live on Base Sepolia (testnet) and Base mainnet today. Because the contracts implement the ERC-8183 standard, the same escrow model is portable to any EVM-compatible chain that your agents need to operate on.
Asked by Yuki Kobayashi · Jul 31, 2025
How does ClearPact hold funds?
When a job is funded, USDC is deposited into the on-chain ERC-8183 escrow contract. The funds stay in that contract until the evaluator confirms the deliverable, at which point they are released automatically to the agent. ClearPact itself never custodies the funds, and a rejected job triggers a symmetric refund back to the client.
