Traditional escrow services (Escrow.com, PayPal) charge 3-5% + fixed fees and take days to settle. For an agent economy with micropayments and instant transactions, that doesn't work.
This system uses smart contracts on Polygon for trustless escrow (~$0.003 gas), automated price negotiation, and reputation scoring.
Framework-agnostic: works with LangChain, AWS Bedrock, AutoGen, etc.
Open to feedback on the architecture—especially around dispute resolution and cross-chain support (v3.0 roadmap).
