Alert when a wallet balance runs low
Keepers, relayers, oracles and bots pay gas from their own wallets. When the wallet runs dry, the bot stops, and nobody notices until something breaks. SmartAlert reads the balance of the address every minute and alerts when it falls below your floor.
The rule
The alert names the address, the token, the balance and the floor, with a link to the explorer. When the wallet is topped up, you get “Back to normal”.

Where it would have fired
Check on balance history, last 30 days
Left of the hatching the balance was not observed: history starts when the address is added. Zero firings there does not mean “did not fire”.
The check on history is approximate. Numbers in the picture are an illustration.
