Solana-Mevbot

fully-auto on-chain pump.fun solana MEVbot leveraging flashloans and the minimal gas fees of Solana to perform sandwich attacks and front-runs on https://pump.fun.

Launch your own MEV engine or start trading with my public program for a .1% fee on successful arbitrage transactions.

Important

Due to the atomic nature of Flashloan operations, if they aren't profitable the transaction will revert and no net profit will be lost.

Loading

• The bot is constantly sniffing the https://pump.fun Solana master SPL for user buys, sells, and token creations containing slippage deficits.

Tip

Bot operators can target any transaction value within their balance threshold. Generally, higher thresholds net consistently viable transactions

• Once a transaction is identified, a flashloan is initiated for the target transaction amount, this requires a marginal amount of collateral.
• The bot will aggresively attempt to front-run the transaction by dynamically monitoring the bribe to the miner and increasing it if necessary so as to be the first transaction mined.
• Depending on the set parameters, the bot will either front-run the Dev's sell to remain in profit, or sell upon the token reaching KOTH.
• The flashloan is then repaid, collateral is reiumbursed and profits are deposited into the operators wallet.
• If the transaction is unprofitable at any point it will be reverted and the flashloan will be repaid, losing no gas or net profit.
