Parent treasury

The parent operates on a single unified USDC balance via Circle Gateway. Idle capital is parked in USYC for yield; FX-side allocations sit in EURC. Children are funded from the USDC bucket on spawn and return capital on termination.

spawn cycle

Funding new children

Every spawn calls createChildWallet() then transfers CHILD_CAPITAL_USDC (default $500) from the parent vault to the new wallet. The transfer is one Circle Wallets API call and one onchain transaction; Paymaster wraps it so gas comes out in USDC.

termination

Capital recapture

On termination, the child’s remaining balance is swept back to the parent vault. If the vault crosses TREASURY_IDLE_THRESHOLD_USDC (default $5,000), the surplus is moved into USYC via the Teller contract for yield.

How Circle products compose

  1. 01ReadGateway returns a unified USDC balance across chains — operators see one number.
  2. 02Spawn-fundParent calls Wallets.create + USDC transfer. Paymaster pays gas in USDC.
  3. 03ParkWhen vault USDC exceeds idle threshold, the surplus is deposited into USYC via the Teller contract.
  4. 04FX legEU agents request a USDC↔EURC swap via StableFX; treasury settles via FxEscrow + Permit2.
  5. 05Cross-chainIf an agent rotates venues to another chain, CCTP v2 burns USDC on Arc and mints on the destination — atomic from the agent's POV.
  6. 06ReclaimOn termination, child balance is swept back to the parent vault and the cycle restarts.
