Swap crypto without KYC, without an account and without custody

A crypto swap on-chain is an exchange of one token for another without moving your assets onto somebody else’s balance sheet. In FBT Swap you connect a wallet you control, choose the pair and the amount, read the quote, and sign. The trade settles between your wallet and the protocol, on the network you picked.

There is no account to create, no email to hand over and no identity document to upload. FBT Swap runs no order book and holds no liquidity of its own: it asks public aggregators for the best route across the decentralised exchanges on that network. Because the tokens never sit in an intermediate account, there is no deposit step and no withdrawal step either.

The supported networks are seventeen: BNB Chain, Ethereum, Polygon, Arbitrum, Base, Optimism, Avalanche, Linea, Sonic, Berachain, Unichain, Monad, Mantle, Scroll, zkSync Era, Robinhood Chain and Solana. The platform fee is 0.70% of the input amount and is shown on screen before you sign, on every supported network; network gas is separate and is paid straight to the chain.

One consequence is worth stating plainly rather than hiding in a footnote: because the key is yours, nobody can reverse a transaction, freeze an asset, or recover a lost recovery phrase. Not us, and not anyone else. The same property that keeps your balance out of an exchange’s reach also makes network and destination address your responsibility, so check them twice — on-chain, "I typed it wrong" is final.
