You commit once
One signature hands your USDC to CCTP through Arcaidia's router. If the handoff fails, everything reverts and you keep your money.
Ethereum ⇄ Arc · Native USDC
An open market for instant USDC
Sending USDC between Ethereum and Arc settles through Circle's CCTP, which is canonical and takes minutes. Arcaidia is a market for that wait: anyone can supply a vault, the recipient is paid in seconds out of one, and Circle's transfer repays that vault with a fee when it lands.
For people sending money, it arrives now instead of later. For people with USDC to put to work, it is short-duration credit against a settlement already in flight.
How it works
One signature hands your USDC to CCTP through Arcaidia's router. If the handoff fails, everything reverts and you keep your money.
It re-reads your transaction from an Ethereum node, checks free liquidity and settlement health, then returns a fee and a verdict. Deterministic — no AI in the decision.
You were paid seconds in. Minutes later CCTP settles and reimburses the liquidity provider, who keeps the fee for the minutes of risk.
If no solver participates, the transfer still completes at CCTP's own speed. Read the ten-stage walkthrough.
