Meet 2Fast, the MEV wallet who made $1.8M in a single transaction:

In January 2024, a Solana searcher known as 2Fast executed one of the most extraordinary publicly documented MEV trades ever seen on chain.
In roughly 20 seconds, the wallet turned 703 SOL into 19,035 SOL, extracting approximately 18,332 SOL in profit about $1.8 million at the time.
What happened?
It started with a fat-finger trade in a low-liquidity dogwifhat ( $WIF ) pool.
A trader placed a very aggressive buy order and because the pool had very little liquidity, that order pushed the token price absurdly high and 2Fast saw it coming.
The bot spotted the mistake:
Using Jito’s block engine, the bot detected a profitable opportunity before the victim’s trade finalized.
The bot realized:
- Someone was about to overpay massively for WIF
- WIF could be bought cheaply first
- Then sold back into the victim’s inflated order
This was a sandwich-style MEV bundle.
2Fast bought WIF first:
The wallet sent: 703.31 SOL to buy: 490,143.9 WIF
This was the setup leg.
It accumulated WIF before the victim’s order pushed price vertical, at roughly the time of the trade, WIF was trading around $0.12
That was approximately the “real” market value the bot was buying near.
The victim’s trade exploded the price:
Because liquidity was thin, the victim’s order caused catastrophic slippage.
The victim effectively bought WIF as if it were worth roughly: $3.3 per token
That means the trader was paying around: 15x above real market price.
2Fast sold into the inflated price:
Only after the victim pushed price vertical did 2Fast sell.
The bot dumped its 490k WIF back into the same distorted market.
It received: 19,035.96 SOL
That created:
Initial capital: 703 SOL
Exit value: 19,035 SOL
Profit: 18,332 SOL
All from a single atomic sequence.
The Jito tip:
2Fast didn’t just “send a transaction", it submitted a Jito bundle.
A bundle lets searchers package transactions together and bid for block inclusion.
The searcher basically tells validators:
Include my bundle in the next block and I’ll pay you, that payment is the Jito tip.
2Fast paid: 890.42 SOL to: jitotip6.sol
(the Jito tip account routed to the winning validator)
The validator associated with the winning block was Figment.
So the validator got paid to include the profitable bundle.
That’s how searchers and validators share MEV.
Why this worked, three ingredients created the perfect storm.
1. A trader made a massive pricing mistake,
Everything starts there.
Without the fat-finger order, no opportunity exists.
2. Low liquidity amplified the error,
Thin pools make prices move violently.
A huge order can distort pricing dramatically, that created the exploitable window.
3. 2Fast was faster than everyone else,
Many bots likely saw it, 2Fast simply won the auction.
By bidding the higher Jito tip it got block priority and captured the trade.

This may be the largest publicly documented single-transaction MEV event on Solana, and possibly one of the biggest ever recorded.
