USDC Escrow Skill

Overview

This skill provides trustless USDC escrow services for agent-to-agent payments on Base. It allows AI agents to create, manage, and resolve payment escrows using smart contracts.

API

All scripts point to https://api.payclawback.xyz by default. To use a different backend, set:

• ESCROW_API_URL - Override API URL (optional)

Available Commands

Create an Escrow

Creates a new escrow holding USDC for a beneficiary.

./scripts/create-escrow.sh <beneficiary_address> <amount_usdc> "<description>" <deadline_hours>

Example: ./scripts/create-escrow.sh 0x742d35Cc6634C0532925a3b844Bc9e7595f2bD28 10 "Payment for data analysis" 48

List Escrows

List all escrows, optionally filtered by state or depositor.

./scripts/list-escrows.sh [--state active|released|disputed|refunded|expired] [--depositor 0x...]

Get Escrow Details

Get details of a specific escrow by ID.

./scripts/get-escrow.sh <escrow_id>

Release Escrow

Release escrowed funds to the beneficiary.

./scripts/release-escrow.sh <escrow_id>

Dispute Escrow

Open a dispute on an active escrow.

./scripts/dispute-escrow.sh <escrow_id>

Resolve Dispute

Resolve a disputed escrow as arbiter.

./scripts/resolve-dispute.sh <escrow_id> <true|false>

• true = release funds to beneficiary
• false = refund to depositor

Claim Expired Escrow

Reclaim funds from an expired escrow.

./scripts/claim-expired.sh <escrow_id>

Workflow Example

1. Agent A wants to pay Agent B for a service
2. Agent A creates an escrow: ./scripts/create-escrow.sh 0xAgentB 50 "Sentiment analysis job" 24
3. Agent B performs the service
4. Agent A releases payment: ./scripts/release-escrow.sh 1

How It Works

• USDC is locked in a verified smart contract on Base
• The escrow has a deadline - funds return to depositor if expired
• Either party can open a dispute for arbiter resolution
• The AI arbiter agent resolves disputes impartially
• All transactions are on-chain and verifiable
