Solana token swap: SPL and Token-2022, signed by you
Swap SPL and Token-2022 tokens on Solana from your own wallet. Balances are read from two paths, the rate and the 0.70% fee are shown before you sign, and custody never moves.

FBT Swap
What you should know
Solana makes token swaps fast and cheap, but two things break them in practice: decimal places and the quality of a balance read. FBT Swap resolves decimals from the chain itself and compares the amount only against a verified scale, so a six-decimal token does not produce a false "insufficient balance".
Balance reads take two paths: the device asks public nodes first, and the FBT Swap server is asked shortly after. The first honest answer wins. If every node refuses, the app does not invent a number — the report says which path answered, what each node said and why, because "insufficient balance" should mean the balance is insufficient, not that a public endpoint was rate-limited.
Both SPL and Token-2022 tokens are supported. When the input is SOL, the rent for creating a destination token account is included in the shortfall calculation, so a transaction does not fail for a missing 2,100,000 lamports that nobody mentioned.
The platform fee on Solana is the same 0.70% of the input amount as on every other supported network, shown on screen before you sign. You sign the transaction, the asset arrives in your wallet, and FBT Swap neither holds the asset in between nor asks for a key.
And, as with any on-chain swap: it is final. Check the destination address and the network twice, and do not expect a swap to produce a profit.
Step by step
How it works
-
Connect a Solana wallet
Connect the Solana wallet you already control, or approve the same connection in a browser wallet. Nothing is deposited with FBT Swap.
-
Choose the token and the amount
Both SPL and Token-2022 tokens are supported. The balance is read from the chain, and the amount gate stays silent until the value has been matched against a verified decimal scale.
-
Read the rate and the fee
The routed rate and the 0.70% platform fee are shown before signing. When the input is SOL, the rent needed for a destination token account (if one has to be created) is included in the shortfall figure.
-
Sign in your wallet
The transaction is signed in your wallet and submitted to Solana. If one node fails to answer a balance read, a second path — our own server — is tried, and the result is reported rather than invented.

FAQ
Frequently asked questions
Clear answers before you decide.
Why did I keep seeing "low balance or check your RPC" on Solana swaps?
In most cases the cause was a failed read rather than a genuinely low balance: decimals could be guessed, Token-2022 mints were not read correctly, and the button state depended on a single node’s answer. Decimals are now confirmed from the chain, both token standards are read together, and balance reads run over two paths with per-node reporting.
Which Solana wallets are supported?
Solana wallets that support browser or WalletConnect connections. The connection happens on the page and your recovery phrase is never requested — any message, email or form asking for a recovery phrase or wallet password is a scam.
Why is the required amount sometimes higher than I expected?
If the destination token account does not exist on-chain, creating it costs roughly 2,100,000 lamports of rent, and that rent is included in the shortfall calculation. It is not a platform fee; it is an on-chain account deposit.
Risk notice
Crypto assets are volatile and on-chain transactions cannot be reversed. You can lose money, including all of it. Nothing here is financial advice.
