What a swap costs on zkSync Era
Gas is paid in ETH by default, but the account model allows paymasters to cover it or to accept another token. Costs are low and, as with other zk rollups, dominated by proving and data publication.
Every swap has three separate recipients and FBT Swap is only one of them. Network gas is paid in ETH 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 zkSync Era
The official bridge from Ethereum is the main inbound route and exchange support is broad. Validity proofs mean no seven-day optimistic wait on the way out.
Before moving a large amount, send a small test transfer and confirm it arrived on era.zksync.network. 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
Addresses on zkSync Era are not always derived the way they are on other EVM chains, because contract deployment works differently. Do not assume an address you control elsewhere is an address you control here — verify before sending.
Check three things every time: the network name your wallet is showing and chain ID 324, 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.
