WOWO Pump Bot is a complete Android source code for a Solana token swap and trading bot that runs entirely on the phone. It is not a compiled binary with a README, and it is not a thin wrapper around someone else's service. Every file that makes the product is in the archive: the native Android shell, the full interface, the trading logic, the build scripts and the licensing system.
The architecture is deliberately simple. The Android layer is one plain Java activity that hosts a WebView. The entire product lives in three files per language: markup, stylesheet and one JavaScript file. There is no Kotlin, no AndroidX, no Gradle, no React, no Vue, no Bootstrap, no bundler and no package install step. You can open the whole application in a text editor, change anything, and rebuild it with four shell scripts in a few seconds.
This makes it a practical starting point if you want to learn how a WebView app is really put together, or if you need a base to build your own variant on.
On the phone it works like this. You paste a wallet private key locally and it stays on the device. The app reads balances straight from public Solana RPC, looks up tokens through DexScreener, and quotes swaps through the Jupiter Swap API with an automatic fallback endpoint. You then configure a cycle: buy size range, sell percentage, delay between buy and sell, delay between cycles, slippage, budget cap and take-profit or stop-loss.
The bot repeats the cycle and keeps running session statistics: cycles completed, buys and sells, SOL in and out, tokens held, estimated PnL, and a success and failure count. A price chart is drawn from raw data without any charting library, and every transaction links out to Solscan for verification.
The licensing system is included in full and is the most reusable part of this package. Activation codes are 16 characters of base32 carrying a 32-bit serial number and a 48-bit HMAC-SHA256 tag. Verification happens completely offline on the device, with no server call, no callback and no phone-home, so the product keeps working even if your hosting does not. A command-line tool prints codes, checks them, and builds a delivery zip containing one code per buyer.
