What a swap costs on Sonic
Gas is paid in S and is very cheap with near-instant confirmation. Low cost is the headline; the fine print is that a chain this young has not yet been stress-tested by a genuine market panic.
Every swap has three separate recipients and FBT Swap is only one of them. Network gas is paid in S and goes to the chain itself. The pool fee sits inside the price you are quoted and goes to liquidity providers. The platform fee is 0.70% of the input. None of the three is taken out of another, and none of them changes after you sign.
Getting assets onto Sonic
The official Sonic gateway handles migration and bridging from Ethereum, and exchange support exists but is narrower than for the major chains. Confirm your destination supports Sonic before withdrawing anything.
Before moving a large amount, send a small test transfer and confirm it arrived on sonicscan.org. FBT Swap is non-custodial and cannot reverse, freeze or compensate a transfer sent on the wrong network — it never holds the funds, so there is nothing for it to return.
What to check before you sign
Liquidity is concentrated in a handful of pools. Depth outside the main stablecoin and native pairs can disappear quickly, so a size that is routine elsewhere may be a large order here. Read the price impact every time.
Check three things every time: the network name your wallet is showing and chain ID 146, the contract address of the token you are receiving, and the size of the approval you are granting. An unlimited approval stays live until you revoke it — it is a separate signature from the swap and deserves separate attention.
What this page does not promise
The rate you see is the best route among the venues queried at that moment, which is not the same as the best price available anywhere. Routing through an aggregator reduces exposure to sandwich attacks but does not make a public transaction immune to them, and FBT Swap does not forecast prices or recommend trades.
FBT Swap cannot audit token contracts you import yourself, cannot restore a lost recovery phrase and cannot reverse a confirmed transaction. The only official domain is fbtswap.ir and the only contact address is fbtswap@gmail.com; we never contact users first.
