Gasmeup

GasMeUp is a zero-install, security-first frontend utility built natively for the Monad Testnet. It allows developers and ecosystem power users to instantly pool and sweep fragmented native MON gas and common testnet ERC-20 tokens (like USDC and WMON) from multiple temporary burner accounts into a single primary address with a single click. The application architecture functions entirely client-side within the browser’s ephemeral DOM memory. It scans target addresses, dynamically queries live fee metrics from the Monad RPC node, calculates precise gas deductions so transactions never fail, and dispatches parallelized sweep sequences to leverage Monad's high-speed block finality. What Problem Does It Solve? Active Web3 participants, smart contract engineers, and dApp testers inherently generate dozens of temporary burner wallets to isolate testing environments and transactions. Over time, this creates massive wallet fragmentation: small, leftover balances of gas and tokens become trapped across various accounts. Manually logging in and out of browser wallet extensions to calculate transaction costs, adjust balances, and send funds one wallet at a time is incredibly tedious and wastes hours of valuable engineering time. GasMeUp solves this operational bottleneck by turning a frustrating, multi-step manual workflow into a fast, one-click automated execution. What Did I Learn?
