x402: agents pay and get paid per call

There are 348 paid operations: 225 at $0.001, 97 at $0.005 and 26 at $0.02. Agents pay in USDs or USDC on Arbitrum or Base. Payment settles only when a call succeeds, so failed calls cost nothing. The Sperax facilitator (x402.sperax.io) sponsors USDs Permit2 gas. As buyers, agents follow limits per payment, per hour, per day and per seller.

Agent bank

The agent wallet on Arbitrum is the bank account. Spending envelopes let funds earn yield until an agent spends them, and a payment over the envelope is refused before signing. Every action is audit-logged. A fail-closed guard chain enforces approvals, risk checks, dollar caps and budgets.

USDs and SPA

USDs is backed by USDC and USDT that earn yield in Aave, Compound, Fluid, Stargate and Curve. It rebases daily: 70% of yield goes to holders and 30% to SPA buyback. SPA is the governance token; 99.99% of SPA bought back is burned. Lock SPA as veSPA for up to 4 years.
