This Skill builds buy and sell transactions for pump.fun tokens, sparing you from manually handling bonding-curve vs AMM routing, quoting, slippage, and transaction encoding details.
Ask the skill to build a buy or sell swap transaction for the provided coin mint and signer wallet using the fun-block API, with your confirmed RPC URL, operation type, and exact amount.

To build a pump.fun swap transaction, you provide the target coin mint, signer wallet, RPC URL, operation type, and exact amount. The Skill auto-detects whether the coin is on the bonding curve or graduated AMM to route the transaction correctly.
MEV front-running protection uses Jito-only submission to prevent public mempool leakage. When enabled, it adds a Jito tip and requires sending the signed transaction exclusively to Jito endpoints, bypassing standard public mempools to secure the swap.
No, manual routing is not required. The Skill uses the fun-block API to auto-detect whether a coin has graduated and automatically chooses the correct swap path between the bonding curve and the AMM.
Before executing a pump.fun token swap, you must confirm your RPC URL, signer pubkey, operation type (buy or sell), mint address, exact amount, and whether to enable optional Jito front-runner protection. It also recommends verifying the token program on-chain.
Yes, you can sell pump.fun tokens back to SOL. The transaction builder supports token-to-SOL sells using NATIVE_MINT, alongside SOL-to-token buys, handling the base64 VersionedTransaction encoding for both operations.
The limitation of Jito-only submission is that it requires sending signed transactions exclusively to Jito endpoints with an attached tip. This avoids public mempool leakage but may incur additional costs and requires endpoint availability for successful execution.
