Before you start

The setup is deliberately short. One wallet capable of holding Sonic and a little S for gas on its chain, one receiving address for the output, and you have everything: a web3 name resolves to the address just as well as the raw string. Read the preview before signing, since it carries the whole trade at a glance, the amounts in and out, the fee, and the network cost. The wallet remains yours throughout and signs nothing you have not seen on screen, which is the whole security posture in one sentence.

Fees and settlement

The cost picture is two lines. The platform side is a flat 0.50% all-in on the swap, quoted before you sign, with no spread and no routing cut behind it. The network side is gas paid in S, settling with sub-second finality blocks on Proof-of-Stake DAG (ABFT), which the preview itemizes per leg. Settlement is on-chain to the address you chose: Credited once the transaction finalizes on-chain, typically well under a second. on this asset, after which the balance is spendable and non-custodial in the fullest sense, yours to move with no platform in the path.

The route runs on the aggregated DEX route, and atomicity is the property that matters: the approved number either happens in full or the transaction reverts with nothing moved but the attempt's gas. There is no resting state between legs where value sits in someone else's hands, and a route that misses your bounds simply fails clean, ready for a fresh quote. Cheap and loud beats silent and expensive as failure modes go.

Buying Sonic: FAQ

Can I buy S for Sonic?
Yes. Buy S non-custodial and it is delivered straight to your Sonic wallet.
What can I buy Sonic with?
Any asset you already hold: the swap leg converts what you spend into S in one signed transaction, quoted all-in before you confirm.
Where does the S I buy go?
Straight to the wallet address or web3 name you provide. U.CASH never holds it; settlement is on-chain and non-custodial from the first confirmation.
Is there a minimum or maximum purchase?
No platform minimum: tokens are divisible, so any amount the network can economically settle works. Very small amounts show their network fee honestly in the preview before you decide.
