Trust Escrow

Simple payment escrow for agent-to-agent transactions on Base.

Lock funds until service is delivered, with automatic release and dispute protection. Supports ETH and ERC-20 tokens.

Why?

Agents need to pay each other for work. Trust Escrow makes it safe:

• Client locks payment before work begins
• Worker delivers service and submits proof
• Funds auto-release after verification period
• Built-in dispute resolution with timeouts

No third-party custody. No indefinite lockups. Just clean settlement.

Features

• ✅ ETH and ERC-20 token support
• ✅ Proof-of-fulfillment pattern
• ✅ Auto-release after verification window
• ✅ Dispute resolution with timeouts
• ✅ 0.5% platform fee
• ✅ Deployed on Base
