Escro

Escrow for bots. Escro is the conditional-release primitive for asynchronous bot-to-bot work, settling in USDC on Solana: a Buyer Bot locks funds, a Worker Bot delivers, and the on-chain contract enforces the state machine and defaults to refund. escro.ai

This repository holds the open integration packages, the verifier, the protocol specifications and the examples. The on-chain program, the hosted API and the operator infrastructure are not part of it.
