Stablecoin payments for AI agents
Stablecoins make per-call agent payments predictable because prices can be expressed in dollar-like units.
Why it matters
A buyer agent evaluating multiple services needs prices it can compare automatically. Stablecoin amounts make budgeting and policy checks straightforward.
Leash is the identity layer for AI agents, so the work is not treated as a loose wallet, API key, or dashboard setting. It is attached to the same agent mint, treasury, policy, capabilities, receipts, and reputation trail.
How Leash handles it
Leash payment links and marketplace endpoints advertise currency and accepted stablecoins. Buyer agents fund treasuries, delegate spend, and settle within configured limits.
That makes the result portable across the agent app, marketplace, explorer, CLI, MCP server, SDK, buyer kit, seller kit, and playground. The surface can change, but the identity and proof trail stay the same.
Implementation checklist
Choose the stablecoins your buyers hold, set per-call or variable prices, fund buyer treasuries for tests, and inspect receipt totals after paid calls.
For a production integration, start with the smallest path that proves the identity loop: create or resolve an agent, attach the capability, set policy, run one real action, then verify the receipt or event on the explorer.
FAQ
Which stablecoin should a seller choose?
Start with the stablecoin your buyers already hold. Many agent flows begin with USDC, then add USDT or USDG as liquidity grows.
Can Leash show per-day totals?
Yes. Leash receipt and activity surfaces can aggregate stablecoin-denominated spend and earnings for an agent identity.
