Refilr watches your onchain wallets and tops them up the moment they run low — automatically, with rules you define and a contract that enforces them.
Send MON into your secure onchain vault. Only you can withdraw it. The automation service can never touch these funds directly.
Add your bot, relayer, or hot wallet. Set a threshold, refill amount, cooldown, and daily cap. Each wallet runs on its own policy.
The off-chain service polls balances continuously. The moment a wallet drops below its threshold, it submits a refuel request.
Every refuel is validated onchain — cooldown, daily limit, vault liquidity, authorization. Funds only move when all rules pass.
The automation key can only call refuel(). It cannot withdraw, change policies, or register wallets. A compromised key cannot drain your vault faster than your own rules allow.
