FAQ
Why not just use a bridge?
Bridges between Ethereum and Arc are slow when they work and unavailable when they don't (Arc's CCTP attestation isn't even live yet). Unstable fills in seconds from USDC that's already on the destination chain — the premium is what you pay for immediacy.
Who holds my money during a trade?
A verified escrow contract — never us. The settlement desk can only push escrowed funds along the committed path (maker, fee wallet, you); it has no withdrawal of its own.
What if the desk goes down mid-trade?
Your payment sits in escrow until you reclaim it: after the timeout (30 minutes, or the block-count fallback), the refund function is yours to call and nobody can block it. Maker liquidity is likewise cancellable at any time.
What if I typo the recipient address?
The recipient is committed when you sign — triple-check it. Delivery goes to exactly that address. If the address exists but can't receive USDC, the funds park in a pull balance recoverable by that address (or redirectable to a clean address of the same party).
Why are premiums allowed to reach 10,000%?
Because scarcity is real: when a chain is starved of USDC, an honest extreme price beats a fake reasonable one. The interface makes the all-in rate impossible to miss and locks extreme fills behind type-to-confirm.
Is there a minimum or maximum?
Minimum: the maker's proceeds must reach 1 USDC. Maximum: whatever the chosen offer has unreserved.
Do I need an account?
No accounts, no KYC on the protocol — it's permissionless contracts plus your wallet. Your order history lives in your own browser; any order is also reachable by its id from any device.
What does it cost to be a maker?
Nothing but gas. You set the premium, earn it on every fill, and the taker pays the 3% service fee on top — it never comes out of your proceeds.
