More about Sonic → Sei

Sonic reaches finality quickly, so a standard CCTP transfer is already fast, with no Fast Transfer fee. From Sonic to Sei, 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 Sei.

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 Sei, Circle's Forwarding Service submits the mint for you, so the recipient doesn't need any SEI for gas on Sei.

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