More about Sonic → Polygon

Sonic reaches finality quickly, so a standard CCTP transfer is already fast, with no Fast Transfer fee. From Sonic to Polygon, USDC typically takes about 1 minute as a standard transfer (Circle's average attestation from Sonic: ~8 seconds); Circle's Forwarding Service submits the mint on Polygon.

On Sonic, with your sendstables wallet the fee payment, approval and burn are gas-sponsored, so you don't need any S for gas — just the USDC you're sending. If you connect your own EVM wallet instead, it pays the S gas for those transactions. On Polygon, Circle's Forwarding Service submits the mint for you, so the recipient doesn't need any POL for gas on Polygon.

CCTP burns and re-mints instead of using a pool, so there's no slippage and no wrapped token. Learn about CCTP.

  4. Review the quote. Check our fee, Circle's fees and the minimum you'll receive. The fee is fixed once you confirm.
