How it spreads.

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 5-minute loop, that wallet buys the token back with 75% of what it earned and sends the tokens to active traders across Solana.

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 5 minutes. Your account is created the first time you connect.

The login signature is not a transaction and cannot move funds.

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.

1. 01

   Connect

   Sign a login message. No funds move.

2. 02

   Tx 1 · create

   Pump.fun create_v2 + optional dev buy. Your wallet signs first, then the token key.

3. 03

   Tx 2 · split

   Fee-sharing config: 5000 bps you, 5000 bps plague wallet.

4. 04

   Verify

   Server reads the on-chain config. Plague share must be ≥50%.

5. 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.

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.

A scheduled job fires every 5 minutes. It has to authenticate with a server-only secret, since it spends real funds. Each run handles up to 6 live tokens.

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.

75% of the earnings buys the token on its bonding curve. Buys below 0.01 SOL are held as pending and added to the next cycle. The other 25% stays in the wallet for rent and network fees. When a token graduates off the bonding curve, buybacks pause and its share is kept.

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.

• 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.

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.
