HostSolana swap: every DEX, one atomic transaction
The NexFlow swap asks Jupiter for the best route across Solana's liquidity and settles the whole trade in a single transaction — and the same page can scan the token you're about to buy.
Every trade on the swap page is a Jupiter-routed atomic swap: one instruction that walks the route across Solana's decentralized exchanges and either fills completely or reverts — you never hold a half-completed multi-hop position. Jupiter is the aggregator doing the routing underneath, which means the price you get reflects the combined depth of the ecosystem's pools rather than whichever single venue you happened to open.
What the swap actually does
You pick the input token, the output token, and the amount. The page quotes the route Jupiter would take, including the price impact and the minimum received at your slippage setting, then builds a single versioned transaction for your wallet to sign. Supported tokens include Token-2022 assets, and the fee model is the house constant: a flat 1% on the swap amount, shown up front — half of which goes to whoever referred you, when a referral exists.
Two wallet lanes reach the same engine. A connected browser wallet signs directly — this is the one surface where Phantom and WalletConnect still live. Or your NexFlow account wallet pays from its deposited balance with no per-trade popup, because the account wallet already holds a session.
The part most swap pages skip
A swap UI answers "what will I get"; it cannot answer "should I be holding this at all". The same page pairs the trade with the scanner: paste a mint before you buy and the read comes back with the things a quote will never tell you — mint and freeze authority state, holder concentration, liquidity depth, sell-side simulation. The two belong together because the worst fills are the ones that were priced fine and fraudulent underneath.
The honest limit: aggregation finds the best available price, not a good trade. On a thin or manipulated pool the best route can still be a bad fill — slippage settings and a risk scan are how you tell those apart. For the settings side, see slippage settings for memecoins.
Swap with the route — and the receipt
Jupiter-aggregated pricing, one signature, a flat 1% fee shown before you sign. Scan first if it's a token you don't know.
Frequently asked
Which DEX does the NexFlow swap use?
All of them at once — the swap routes through Jupiter, Solana's liquidity aggregator, so a single atomic transaction can split across whichever pools price best. You sign once; the route either fills completely or reverts.
What does the swap cost?
A flat 1% fee on the swap amount, shown before you sign — no hidden spread on top of the Jupiter quote. When a referral exists, half of that fee goes to the referrer on-chain in the same block.
Can I swap without connecting Phantom?
Yes — the NexFlow account wallet pays from its deposited balance with no per-trade popup. External wallets still work on this page for anyone who prefers to sign each transaction.
Does the swap support Token-2022 assets?
Yes — the transaction builder handles both SPL and Token-2022 mints, including tokens with transfer fees, and the quote reflects what the route actually delivers after those mechanics.
