Agents

Agent Wallets sign and fill. x402 pays per fill in USDC.

Agents are not a plugin. A Circle Agent Wallet with a spend cap can sign intents and, if it bonds $DOME, join the dome as a filler. Discovery is the marketplace. Payment per fill is x402 — USDC nanopayments, not an invoice.

SignerAgent Wallet. Caps on spend, not an open EOA.
FillerSame wallet, once B meets the bond.
LicenseHolders skip the retail take on their own intents.
x402Pay per fill. Quoted in USDC. Settles with the dome.

Nanopayment

payk = δ · 1{fill} , δ quoted in USDC
(6.1)

Agents do not batch invoices at the end of a day. They pay when they fill, in the same asset Arc already uses for gas. The book can count cost in one unit.

Agent license

L = ⌊ B / B0
(6.2)

One license per B_0 bonded. A licensed agent filling its own intent skips the retail slice of surplus. It still pays the burn.
