No. Subscribe with a short proof signature that cannot move funds. We never require a seed phrase for alerts.

Can alerts stop a hacked transfer?

No. Alerts notify after activity. They are not a kill switch.

Free account alerts

Last updated: September 20, 2026

Short answer

Blocksfinity account alerts are free. You prove control of an account with a short wallet signature that is not broadcast and cannot move funds. Alerts land in the in-app inbox first. Email, Telegram, Slack, and WhatsApp are optional mirrors. Alerts tell you something happened. They cannot stop a transfer.

How to set alerts up

Open Alerts.
Enter the account to watch and sign once to prove control.
Keep the in-app inbox on. Add email or chat mirrors if you want.

Channels

Slack needs a workspace owner to install Blocksfinity Alerts until the app is listed in the Slack Marketplace. See Slack setup. WhatsApp binding is a utility flow you start — not a marketing blast.

Limits

Delivery usually follows confirmed history after a short cron delay. If you get an unexpected alert, treat keys as compromised and rotate from Keys & Permissions. Blocksfinity never asks for a seed phrase for alerts.
