xPhantom SuperSwap: The Cross-Chain Swap Engine That Chains Pump.fun, Jupiter, PancakeSwap & ChangeNOW

October 11, 2026·SOLbin Team

One Swap, Four DEXs, Two Chains

Cross-chain trading has always been a chore. You sell on one DEX, copy the tx hash, open a bridge, paste the deposit address, wait, switch networks, open another DEX, and buy. Five tabs, three signatures, two network switches, and a prayer that the price hasn't moved while you waited.

xPhantom SuperSwap collapses all of that into a single interface inside SOLbin. It chains four protocols — Pump.fun, Jupiter, PancakeSwap, and ChangeNOW — into one orchestrated flow that executes leg by leg, with you signing each step locally in your own wallet.

No tabs. No copy-paste. No manual network switching. Just a direction toggle and a swap button.

Two Directions, One Engine

xPhantom SuperSwap supports two cross-chain directions, each solving a real trading problem.

Direction 1: Solana → Cross-Chain

You hold a pump.fun token and you want out — into Bitcoin, BNB, Ethereum, or any of the eight chains SOLbin supports. Normally that means:

Sell the token on pump.fun for SOL
Send SOL to a centralized exchange
Withdraw to the destination chain
Pay withdrawal fees and wait 24 hours

xPhantom SuperSwap does it in one flow:

Sell on pump.fun (bonding curve) or Jupiter (graduated token) → SOL lands in your wallet
Route SOL → destination chain via ChangeNOW → your BTC/BNB/ETH address receives the funds

The platform fee is calculated transparently, gas is reserved, and the ChangeNOW deposit address is generated automatically. You see the estimated output before you confirm.

Direction 2: BNB Chain → pump.fun

This is the reverse — and it's the one degens have been asking for. You hold a BSC token and you want to buy a pump.fun token that's heating up. The traditional path is painful:

Sell the BSC token on PancakeSwap for BNB
Send BNB to an exchange
Trade BNB → SOL
Withdraw SOL to your Solana wallet
Open pump.fun and buy

xPhantom SuperSwap does it in three steps:

Sell on PancakeSwap (BSC token → BNB)
Route BNB → SOL via ChangeNOW (cross-chain, 10–60 min)
Buy on pump.fun once SOL arrives (Phase 2 panel, triggered when you're ready)

Steps 1 and 2 execute immediately. Step 3 is a separate panel that appears once the cross-chain SOL is in your wallet — because ChangeNOW delivery takes 10–60 minutes, and you shouldn't have to stare at a loading spinner the whole time. Paste the pump.fun token CA, enter the SOL amount, and buy. Your SOL balance is polled automatically so you know when the funds have landed.

How It Works Under the Hood

xPhantom SuperSwap is not a single transaction — it's an orchestrated sequence of independent on-chain actions, each signed by your own wallet. Here's the full flow.

Leg 1: The DEX Sell

Solana direction: If the token is still on the pump.fun bonding curve, the sell goes through PumpPortal — pump.fun's own trade API — with escalating slippage (15% → 30% → 50%) to ensure the sell lands even on volatile tokens. If the token has graduated (bonding curve complete), the sell routes through Jupiter, which aggregates across Raydium, Orca, Meteora, and pump.fun AMM to find the best price.

BSC direction: The sell goes through PancakeSwap V2 router. The contract approves the router, then swaps the token for BNB at the current market rate with a 5% slippage tolerance.

In both cases, the transaction is signed locally — by your Phantom extension (Solana) or your SOLbin native wallet (PIN-unlocked keystore) or your MetaMask (BSC). The private key never leaves your device. SOLbin never sees it.

Leg 2: The Cross-Chain Bridge

Once the sell lands, the proceeds are routed to ChangeNOW — a non-custodial cross-chain exchange that doesn't require an account or a deposit hold. SOLbin calls ChangeNOW's API to generate a one-time deposit address for the specific trade.

The platform fee is deducted from the sell proceeds before the deposit. For the Solana direction, the fee is sent to the SOLbin fee vault via a Solana multi-send instruction in the same transaction as the ChangeNOW deposit — so the fee and the deposit land atomically. For the BSC direction, the fee is sent to the BNB fee vault.

The cross-chain delivery takes 10–60 minutes depending on network congestion. ChangeNOW handles the swap at their end; your destination wallet receives the funds directly.

Leg 3: The Destination Buy (BSC direction only)

For the BNB → pump.fun direction, a Phase 2 panel appears after the cross-chain route is initiated. This panel polls your Solana wallet's SOL balance every 15 seconds. When the ChangeNOW SOL arrives, you paste the pump.fun token CA, enter how much SOL to spend, and click Buy on pump.fun.

The buy goes through PumpPortal with the same escalating slippage logic as the sell. You sign locally in Phantom or your SOLbin wallet. The transaction is broadcast with Jito MEV protection for atomic block inclusion.

Self-Custody at Every Step

This is the part that matters: xPhantom SuperSwap never holds your funds.

Every leg is signed locally in your wallet. SOLbin constructs the transaction, your wallet signs it, and the transaction is broadcast directly to the chain.
The ChangeNOW deposit address is a one-time address generated for your specific trade. ChangeNOW processes the swap and sends the output to your destination wallet. SOLbin never touches the funds in transit.
The platform fee is deducted from the sell proceeds and sent to the SOLbin fee vault in the same transaction as the deposit — not held in an intermediary account.
Your private keys never leave your device. SOLbin's servers never see them.

This is the same self-custody model that powers every other feature in SOLbin. xPhantom SuperSwap is just a new orchestration layer on top of the same wallet infrastructure.

The Routing Path Visualizer

Every xPhantom SuperSwap panel includes a routing path visualizer — a horizontal stepper that shows the three legs of the swap and their current status:

Sell on [DEX] — bonding curve or Jupiter or PancakeSwap
Route [asset] → [destination] — ChangeNOW cross-chain
Receive [destination asset] — at your wallet (or buy on pump.fun for the BSC direction)

Each step lights up as it completes. A spinner shows on the active step. A checkmark shows on completed steps. You always know exactly where your swap is in the flow.

What About Fees?

xPhantom SuperSwap applies the standard SOLbin platform fee to the sell leg — the same fee that applies to any swap in the wallet. The fee percentage is configurable by the admin and can be set to 0% during promotions (like Wild Wild West Week).

The fee is transparently shown in the quote summary before you confirm:

Selling amount and estimated SOL/BNB received
Platform fee (percentage and amount)
Estimated gas (reserved from the proceeds)
Estimated received at the destination chain

ChangeNOW also charges a small spread on the cross-chain swap, which is built into the quoted output amount. There are no hidden fees.

Which Wallets Work?

xPhantom SuperSwap works with the same wallets that power the rest of SOLbin:

Solana leg: Phantom extension, Solflare, or SOLbin's native PIN-unlocked keystore
BSC leg: SOLbin's native EVM wallet (PIN-unlocked) or MetaMask

You can mix and match — use Phantom for the Solana side and the SOLbin native wallet for BSC, or any combination. The direction toggle at the top of the panel switches between the two flows.

Try It Now

xPhantom SuperSwap is live in the Wallet Hub under the Swap tab. Open it, pick a direction, paste a token address, and see the routing path light up.

Solana → Cross-Chain: Sell any pump.fun or Jupiter token and route the SOL to BTC, BNB, ETH, or five other chains.
BNB → pump.fun: Sell any BSC token on PancakeSwap, bridge to SOL, and buy a pump.fun token — all from one panel.

No new accounts. No new extensions. Just the wallet you already have.

xPhantom SuperSwap is the latest step in SOLbin's mission: one self-custody wallet, every chain, every DEX, zero friction. The phantom doesn't hold your keys — it just routes your trades.
