Autonomous agents can now perform multi-leg atomic trades

This post explores the challenge of multi-leg atomic trades for autonomous agents, where a single trade involves multiple sequential steps. Current systems often rely on a "settle-then-hope" approach, leaving agents vulnerable to inventory, price, and counterparty risks if any leg fails. The proposed solution uses a single hashlock across all legs of the trade, ensuring that either all legs settle simultaneously or none do, thus preventing intermediate states where an agent is stranded with unwanted assets. A descending timelock ladder is also introduced to manage the timing of claims and refunds across the multiple legs. AI

    Multi-leg trade atomicity: when one preimage has to settle three legs at once

    <p>An autonomous agent kicks off a three-leg trade. Leg one: it pays BTC and receives ETH. Leg two: it routes that ETH to a second counterparty for USDC. Leg three: that USDC settles to a vendor for a compute reservation. Legs one and two clear. Then the third counterparty goes q…
