The team behind Tsunammi.io breaks down how MEV extraction happens in the first block of a Solana token launch — and what operators can do before it costs them their chart.
Tsunammi, the Solana token market infrastructure platform, has published a technical research guide on sniper bot extraction in Solana token launches. The guide covers how bots detect new tokens across multiple launch venues, what the damage looks like on-chain, and what project teams can do to protect their launch before the token goes live.
The full article is available on Medium.
How Sniper Bots Detect a Solana Token Launch
Sniper bots do not monitor social channels or wait for announcements. They run persistently against Solana validator transaction streams and watch for specific on-chain program instructions. The exact trigger depends on the launch venue. On PumpFun, it is the create or create_v2 instruction. In every case, the bot uses the program’s Anchor IDL to decode the instruction and extract token parameters in real time.
The result is zero-delay detection. There is no window between a token becoming tradeable on-chain and a well-configured bot being aware of it. By the time a project’s community sees the contract address posted in a Telegram group, bots have already parsed the mint, calculated the entry price, and submitted buy transactions to the validator.
Multiple working implementations of this approach are publicly available on GitHub. The infrastructure is not exotic — it runs on a standard RPC connection with a transaction listener and a few hundred lines of TypeScript. Any technically capable actor can run a sniper bot against any Solana launch venue.
What Happens Without Anti-Snipe Protection
The sequence on an unprotected launch is consistent across venues. Sniper bots enter in block zero at the lowest available price. Organic buyers arrive in blocks 5–20 at a price already elevated by bot positions. Bots exit into that organic wave. The chart shows a steep pump followed by a dump, organic holders are left underwater, and the pattern reads as a rug to outside observers. Volume dies.
This is the default outcome on the majority of unprotected Solana token launches. The structural exposure remains the same regardless of where the token is launched. The bots are always running, and without a deliberate first-block strategy the project team will never be the first buyer on their own token. The question is not whether snipers will find the launch. They will. The question is whether the team has taken block zero before them.
Bundle Execution: Closing the Gap to Zero
A transaction bundle packages multiple transactions into a single atomic unit — all execute together, or none do. For a token launch this means including pool creation, liquidity addition, and the team’s initial buy in the same bundle. No external transaction can land between them.
For a PumpFun launch, the bundle contains token creation and the first buy. The outcome is the same: the team occupies block zero by design, not by luck.
One practical detail: bundles compete for block inclusion via a validator tip. Underbidding on tip at a busy launch window is one of the more common reasons first-block strategies fail in practice. The tip needs to be calibrated to the expected competition at launch time.
Tsunammi’s launch tooling is built on bundle execution. Operators configure bundle parameters — liquidity amount, initial buy size, wallet distribution — and the platform handles execution.
Multi-Wallet Distribution and Liquidity Depth
Two additional factors determine how well a launch holds after block zero.
Wallet distribution. Concentrating early allocation in a single address is a visible on-chain signal. Traders who check holder distribution before deciding whether to hold see one wallet controlling a large percentage of supply and treat it as an exit risk. Distributing the initial allocation across multiple wallets makes the holder map look more organic and makes the chart more resilient when external snipers exit — their sells hit a spread market rather than a thin one.
Liquidity depth. First-block protection does not eliminate all sniper activity. Fast bots will still enter in the first few blocks. What determines the chart impact is pool depth. A $50,000 sell into a $150,000 pool moves price far less than the same sell into a $12,000 pool. Teams need to define their depth target before launch and have capital ready. Adding depth after the chart has already taken damage rarely recovers the situation.
Anti-Snipe Launch Checklist
- Bundle configured with token/pool creation, liquidity addition, and initial buy as one atomic package
- Validator tip calibrated for expected block competition at launch time
- Initial allocation distributed across multiple wallet addresses
- Liquidity depth target defined and capital allocated before launch
- Real-time monitoring active for the first 10 minutes of trading
- Full configuration tested on devnet before mainnet execution
This checklist applies to Solana token launches where token creation and liquidity provision happen on-chain.
About Tsunammi
Tsunammi is a Solana token market infrastructure platform for operators who need execution control over launch and post-launch phases. The platform covers first-block launch execution via transaction bundles; multi-wallet initial distribution; liquidity depth management; and real-time market monitoring. Built for teams that treat token market operations as an engineering problem, not a luck problem. Users can see more at tsunammi.io.
