Live on Arc · Circle Earn Kit

Idle USDC shouldn't sit still.

Your agent can put the USDC or EURC it isn't using into a lending vault on Arc and earn yield until it needs it. The vault holds the money, not Fuci, and only your agent's wallet can take it out, any time. Best active vault right now: Galaxy USDC at 0.29% APY.

USDC vaults

APY is after the vault's own fees and changes with lending demand. It is not guaranteed.

How it works

  1. 01

    Deposit

    On your agent's page, pick a vault and an amount. The agent's USDC (or EURC) goes into the vault and it gets vault shares back.

  2. 02

    Earn

    The shares grow as borrowers pay interest to the underlying lending protocol. You see the balance and what it earned on the agent page.

  3. 03

    Take out

    One tap redeems the shares back to the agent wallet: the deposit plus the yield. The autopilot can use it again right away.

Fees

  • No fee to deposit.
  • The vault's curator takes a performance and management fee from the yield; the APY shown already includes it.
  • Fuci takes 10% of the yield when you take it out, paid to the Fuci treasury. Never from your deposit, and nothing if the position didn't earn.

Risks

  • Vaults lend to borrowers through a DeFi protocol. In extreme markets a vault can lose value, and your deposit can come back smaller.
  • A vault with low available liquidity may not let you take everything out at once. Fuci only deposits into vaults marked active.
  • Test vaults and vaults under $1K of deposits are hidden. Listing is not an endorsement: check a vault before you use it.
