Testnet

Swap & bridge

Swap

Swap between USDC, EURC, and cirBTC on Arc. Powered by Circle App Kit. Live quote refreshes as you type the amount, then one tap to confirm.

Default pair is USDC → EURC. To swap a different pair, change the "From" and "To" token chips on the swap screen.

Bridge

Move USDC out of Arc to Base, Ethereum, Polygon, or Arbitrum. Uses the same CCTP V2 plumbing that powers Universal Receive, except in the reverse direction.

Pick the destination network, type the amount, confirm. The funds arrive on the chosen chain at the same address Circle holds for you across EVM chains. From there you can pull them into MetaMask, Coinbase, etc.

What about cirBTC?

cirBTC can be swapped (USDC ↔ cirBTC ↔ EURC) but cannotbe bridged. Circle's bridge kit is USDC-only today. We'll wire this in when Circle ships cirBTC bridge support.

Fees

  • Swap: Circle's App Kit takes a small spread (slippage cap default 3%). On Arc testnet, no real value moves.
  • Bridge: Arc-side gas (paid in USDC, very small), plus CCTP V2 Fast Transfer fee (also tiny, often free at low amounts).
