Refilr — Monad Spark Hack

Automated gas-refill vault: deposit MON, register operational wallets with refill policies, and let the automation service keep them topped up. The contract validates every rule itself — automation only proposes.

Structure

contracts/    WalletOpsVault.sol + compiled ABI (Remix-ready, no imports)
automation/   Node.js service that polls wallets and calls refuel()
frontend/     Next.js + wagmi dashboard (depot tank + fuel gauges)

Quick start

1. Contract: paste contracts/WalletOpsVault.sol into Remix, compile (0.8.24), deploy to Monad Testnet with _owner = your address and _automationOperator = your automation wallet's address.
2. Automation: cd automation && npm install, fill in .env (see .env.example), npm start. Fund the automation wallet with a little MON for gas — separate from the vault's balance.
3. Frontend: cd frontend && npm install, fill in .env.local, npm run dev.

Each subfolder has its own README with details.
