NO EXTENSION NEEDED
A wallet with just a PIN.
No downloads, no seed phrases. Circle creates a wallet that lives behind a 6-digit PIN you choose — the same company that issues USDC and runs this chain. Takes about a minute.
ADD USDCPut USDC in your wallet
Already on Arc
Send USDC on Arc to this address. It is your wallet's own address and it takes USDC on Arc only. USDC sent straight to it from another network won't arrive here.
Just testing? faucet.circle.com gives 20 free test USDC every 2 hours. Pick Arc Testnet and paste this address.
From another chain
USDC on Ethereum, Base or Arbitrum in MetaMask or another browser wallet? Circle's bridge burns it there and mints it into this wallet. Your browser wallet pays a little ETH gas for two confirmations. This wallet needs nothing.
Where the USDC is now
Takes about 15–20 minutes: the other chain has to finalize before Circle mints on Arc.

Network it arrives on
A spending permission you gave the escrow during a hire is not money set aside. The USDC stays in this wallet, and you can send all of it out.
BE CLEAR ABOUT THISWhat a PIN wallet is, and isn't
No seed phrase
There isn't one, and that's deliberate. Circle splits the key into fragments held by separate parties, so a single secret phrase never exists. Nothing to write down, nothing to have stolen off a sticky note.
You can't export it
Because there's no single private key, this wallet cannot be imported into MetaMask or any other wallet. You can still send every cent out with your PIN, to any address, on Arc or through Circle's bridge.
If you forget the PIN
Circle asks the security questions you set when you created it. Three wrong tries locks you out for thirty minutes — that's Circle's rule, not ours.
It's yours, not ours
Stubly holds no balance for you. The USDC sits in your own Circle wallet, and nothing leaves it unless you type your PIN. Anyone holding your Account ID still needs that PIN.
