## Sample excerpt

# Agent-to-Agent Escrow Pattern

Pure x402 unlock assumes one merchant. Agent-to-agent work needs escrow: fund, deliver hash, confirm, or dispute. This pattern documents the state machine and messages for open markets (including 85/15 style fees where relevant). Complements seller/buyer agents.

When to use: open listings, freelance agents, multi-party deals.

**Price:** $9.99 USDC on Base via x402 unlock.

**Standards:** x402 payments · ERC-7857 sealed skill model · agent-swarm ready.

Operator notes for Agent-to-Agent Escrow Pattern: treat this as a capability pack you wire into real tools—not a certification or hosted SaaS. Pair it with free evaluation at /skills/agent-to-agent-escrow-pattern/outline.json before paying. Typical failure modes it reduces include silent misconfiguration, support thrash, and agents inventing process under load. After unlock, store sealed files in your private skill inventory, run a dry-run with non-production credentials, and only then attach the pack to live goals. Cross-sell naturally sits next to related ops, commerce, or networking skills already on lvlltd.com so agents can compose a ladder instead of a one-off purchase.
