01
The outbreak
Plague Launcher is a Pump.fun launchpad where every token pays for its own spread. Half of each token's creator fees go to the plague wallet. On a 2-minute loop, that wallet protects 50% of incoming fees as SOL treasury, buys the token back with 37.5%, and sends the tokens to active traders across Solana.
Launch
Your wallet creates the token and locks in the 50/50 split on-chain.
Buyback
37.5% of each token's claimed fees buys that same token.
Spread
Up to 250 new holders per token, every cycle.
02
Wallet access
There are no usernames, emails or passwords. Connect Phantom, Solflare or Backpack and sign a short login message with a timestamp. The server checks the signature (ed25519) and rejects messages older than 2 minutes. Your account is created the first time you connect.
The login signature is not a transaction and cannot move funds.
03
Releasing a strain
Your image and metadata are uploaded to Pump.fun's IPFS. The server then builds the launch and simulates it on mainnet before your wallet ever sees it. If it would fail (for example, not enough SOL for the dev buy), you get the exact reason instead of a broken prompt.
- 01
Connect
Sign a login message. No funds move.
- 02
Tx 1 · create
Pump.fun create_v2 + optional dev buy. Your wallet signs first, then the token key.
- 03
Tx 2 · split
Fee-sharing config: 5000 bps you, 5000 bps plague wallet.
- 04
Verify
Server reads the on-chain config. Plague share must be ≥50%.
- 05
Live
Token joins the outbreak cycle.
Transaction 1 calls Pump.fun create_v2, plus a dev buy if you chose one. Your wallet signs first. Then the server adds the new token's key signature and sends it, so wallets can add priority fees without breaking anything.
Transaction 2 creates the fee-sharing config. It has to be separate because both together go over Solana's 1232-byte transaction limit. It's built with a fresh blockhash after transaction 1 lands.
04
The 50/50 fee split
Pump.fun pays a creator fee on every bonding-curve trade. The sharing config sends 5000 bps to you and 5000 bps to the plague wallet. Pump.fun's program enforces this split, not our server.
A token only goes live once the server reads the on-chain config and finds the plague wallet at 50% or more. The browser can never set a token's status. If a creator later removes the plague wallet, the token stops being fed and is marked Cured.
05
The outbreak cycle
A scheduled job fires every 2 minutes. It has to authenticate with a server-only secret, since it spends real funds. Each run handles up to 6 live tokens.
06
The buyback
For each token, the plague wallet claims its fee share and measures its own SOL balance before and after. The difference is that token's earnings, so fees from one token never buy another.
50% of new earnings builds a protected SOL treasury in the plague wallet. 37.5% buys the token on its bonding curve. Buys below 0.01 SOL are held as pending and added to the next cycle. The remaining 12.5% funds rent and network fees. Treasury is tracked separately and excluded from buyback and airdrop spending. This applies to new claims; existing SOL is not reclassified. When a token graduates off the bonding curve, buybacks pause and its share is kept.
07
The spread
Recipients come from wallets that recently paid fees on Pump.fun, so they're real, active traders. Wallets already infected with that token are skipped (each wallet can receive a given token only once).
The bought tokens are split evenly. Several transfers are packed into each transaction, and enough SOL is held back to open each recipient's token account. Bigger claims reach more wallets.
| Plague claim | Treasury (50%) | Buyback (37.5%) | Costs (12.5%) | New wallets it can open* |
|---|---|---|---|---|
| 0.1 SOL | 0.05 SOL | 0.037500000000000006 SOL | 0.013 SOL | 4 |
| 0.5 SOL | 0.25 SOL | 0.1875 SOL | 0.063 SOL | 28 |
| 1 SOL | 0.5 SOL | 0.375 SOL | 0.125 SOL | 58 |
| 5 SOL | 2.5 SOL | 1.875 SOL | 0.625 SOL | 299 |
*Each new holder needs a token account (~0.00207 SOL rent) plus a tiny share of the fee. Drops are packed ~6 per transaction. Capped at 400 per token per cycle. Leftover operating funds carry over. Protected treasury is never used for these costs.
08
Safeguards
- The plague wallet's private key exists only on the server. Its public address comes from that key and is never set separately.
- Launch transactions are simulated before signing and checked on the server (correct payer, correct token) before they're sent.
- Each token's key is stored in a private place only the server can read, and is used only to co-sign that token's launch.
- Status changes (draft → live → cured) come only from on-chain verification.
- The platform can pause all launches and outbreak cycles.

Risks
Memecoins are extremely risky. Buybacks don't guarantee that a price will go up. People who receive drops may sell them straight away. Pump.fun can change its programs or fees at any time, and network congestion can delay cycles.
Plague Launcher does not endorse any token. Only spend what you can afford to lose.
