What a swap costs on Polygon
Gas is paid in POL. Transactions cost a fraction of a cent most of the time, and the practical failure mode is not cost but congestion during popular mints, when a low gas price leaves a transaction stuck behind better-paying ones.
Every swap has three separate recipients and FBT Swap is only one of them. Network gas is paid in POL 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 Polygon
Both the official bridge and third-party bridges serve this chain, and exchanges support direct Polygon withdrawals. Check which USDC you are receiving: the native issuer version and the older bridged version both circulate here and they are different tokens.
Before moving a large amount, send a small test transfer and confirm it arrived on polygonscan.com. 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
The two USDC variants are the single most common source of confusion on this network. A balance that "disappeared" is almost always the other variant sitting at a different contract address, visible in the explorer under your same wallet.
Check three things every time: the network name your wallet is showing and chain ID 137, 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.
