How it works
- Pick a chain and what you pay with.
USDC goes straight to the bridge. Anything else is swapped into USDC first by LI.FI, on the chain you are on.
- One bridge signature.
Circle's CCTP burns the USDC and its Forwarding Service mints it on Arc for you. You never need gas on Arc.
- Buy on the floor.
If you picked a coin, the bridged USDC buys it on its bonding curve as soon as it lands; one more signature, on Arc.
Supported chains
Fast transfers arrive in about 20 seconds where Circle offers them. From Solana, SOL or any Solana token becomes USDC on Arc in one LI.FI route, signed in Phantom, Solflare or Backpack; the USDC lands at your Arc address (Phantom carries one, or type it in). From Sui, USDC goes over Circle's CCTP and lands in seconds, signed in Slush, Phantom or Suiet; SUI and other Sui tokens are swapped into USDC first by LI.FI, which makes two signatures. Sui's network fee is paid in SUI; about 0.01 SUI in the wallet is enough. EURC (from Base, Avalanche, World Chain or Ethereum) and cirBTC (from Ethereum) arrive as themselves through Circle Gateway, under "EURC · cirBTC": a deposit into your Gateway balance, credited once that chain finalizes it (seconds on Avalanche, about 15 to 20 minutes elsewhere), then one signature sends it to Arc.
Fees
- Circle
- A few basis points on fast transfers (none on standard), plus about 0.02 USDC to mint on Arc for you.
- LI.FI swaps
- The pool's price and a fixed fee of a cent or two.
- Circle Gateway
- EURC and cirBTC: the source chain's gas and the mint on Arc, taken from your Gateway balance and shown before you sign.
- A NEW ONE
- On mainnet, 0.25% of a non-USDC payment goes to the floor, shown as its own line. On Gateway the same 0.25%, only when the extra Gateway gas it causes stays under a fifth of it; otherwise nothing.
