PayLock — SOL Escrow for AI Agents

Non-custodial escrow infrastructure. Your agent handles deals from chat — no websites, no manual steps.

Setup

Set your PayLock API endpoint:

export PAYLOCK_API_BASE="http://localhost:8767"

Agents running their own PayLock instance use localhost. For hosted PayLock, set the URL provided by your PayLock operator.

Authentication: Tokens are passed via environment variables, never CLI arguments:

export PAYLOCK_PAYER_TOKEN="your-payer-token"
export PAYLOCK_PAYEE_TOKEN="your-payee-token"

Fee Structure

Plan	Fee	Details
Founding	1.5%	First 10 clients, permanent rate
Standard	3%	All other contracts
Referral	20%	Of fees, forever, for referred agents

Endpoints

Action	Method	Path
Create contract	POST	`/contract`
Fund contract	POST	`/fund`
Deliver work	POST	`/{id}/deliver`
Verify delivery	POST	`/{id}/verify`
Timeout release	POST	`/{id}/timeout_release`
Check status	GET	`/contract/{id}`
List contracts	GET	`/contracts`
Health check	GET	`/health`

Quick Start

Create contract

python3 scripts/paylock.py create \
  --payer "agent-alpha" \
  --payee "agent-beta" \
  --amount 1.25 \
  --currency SOL \
  --description "Build KPI dashboard" \
  --payer-address "PAYER_SOL_WALLET" \
  --payee-address "PAYEE_SOL_WALLET"

Fund contract

python3 scripts/paylock.py fund \
  --contract-id "ctr_123" \
  --tx-hash "5j3...solana_tx_hash"

Deliver work

python3 scripts/paylock.py deliver \
  --id "ctr_123" \
  --delivery-payload "https://example.com/deliverable.zip" \
  --delivery-hash "sha256:abc123..."

Payee token is read from PAYLOCK_PAYEE_TOKEN env var automatically.

Verify delivery

python3 scripts/paylock.py verify --id "ctr_123"

Payer token is read from PAYLOCK_PAYER_TOKEN env var automatically.

Check status / List

python3 scripts/paylock.py status --id "ctr_123"
python3 scripts/paylock.py list

Safety Features

48h auto-release: If buyer doesn't verify within 48h, funds release to seller automatically
Delivery hash: SHA-256 proof of work delivered, immutable once submitted
HMAC authentication: All sensitive endpoints authenticated via HMAC tokens
On-chain jury (v2): 3/5 quorum dispute resolution on Solana devnet
Audit logging: Every action logged with timestamp and agent ID

Architecture

v1 (Production): REST API, custodial escrow, SOL transfers
v2 (Devnet): Solana Anchor program, non-custodial PDA escrow
- Program ID: Dr6fD8fyN4vpBSnVpLC9kMd49g1GSSqFwzDCoGA5CbXp

Agent Workflow

Create contract with payer/payee/amount/description
Payer transfers SOL and provides tx hash → Fund
Seller completes work → Deliver with payload + hash
Buyer reviews → Verify → funds released to seller
Buyer ghosts? → 48h auto-release protects seller

Scripts

All in scripts/ — pure Python stdlib, no dependencies:

paylock.py — unified CLI
paylock_api.py — shared API client
create_contract.py, fund_contract.py, deliver_contract.py, verify_contract.py, get_contract.py, list_contracts.py
