Automated MetaMask Low Gas Balance Alerts
Every hour, WebRun opens your MetaMask portfolio, reads the native balance on each watched address and network, compares it with the floor you set, alerts Slack the moment one drops below, and keeps a Trello card open until the wallet is topped up. WebRun only reads balances and never moves funds.
How do I get alerted when my wallet runs low on gas?
WebRun checks your MetaMask portfolio every hour, reading the native balance on each watched address and network against the floor you set. It alerts Slack the moment one drops below and keeps a Trello top-up card open until it recovers, so scheduled transactions never start failing. It only reads balances.
- A warning arrives while there is still time to top up
- Balances are checked per network, not just per wallet
- WebRun reads only and never moves a single token

MetaMask - read balances per network
metamask.io
WebRun opens MetaMask to read balances per network. - Open the MetaMask portfolio view and read the native balance on each address you watch
- Do the same per network, since a wallet can be funded on one chain and empty on another
- Compare each balance with the floor you set for that address and network
- Work out the burn since the last few runs so a fast drain is visible as well as a low number
Done when Every watched address and network has a current balance measured against its floor.

Slack - alert when a wallet drops below the floor
slack.com

Trello - keep a top-up card open
trello.com
WebRun opens Trello to keep a top-up card open. - Open a top-up card the first time a wallet crosses its floor, with the address label, network, and shortfall
- Update the card each hour with the current balance rather than creating duplicates
- Close the card once the balance is back above the floor. WebRun never sends or swaps funds to fix it
Done when Each wallet under its floor has one open card that closes when the balance recovers.
How is each run configured?
Secure by default
Connect once, stays signed in
WebRun signs in once and keeps each session in a persistent environment, so every run picks up right where it left off.
Every action is checked against this policy before it runs.
Questions, answered
Will it move or spend any funds?
No. WebRun only reads balances and reports them. It never sends, swaps, bridges, or approves a transaction, so every top-up is made by a person from their own wallet.
Does it need my seed phrase or private key?
No. It reads the portfolio view for the addresses you tell it to watch. Recovery phrases and private keys are never requested, entered, or stored by this workflow.
How often will it alert me?
Once per wallet per crossing. It checks hourly but keeps one open Trello card and does not repeat the same Slack alert until the balance recovers and drops again.
