Sentinel

Watch a contract.

Paste a token address and your email. If the contract changes, we email you: a new owner, ownership renounced, a mint, blacklist or pause function appearing, a proxy upgrade, or the supply changing. You confirm by email first.

Sentinel watches the contract only, every 30 minutes at most: owner, ownership, mint, blacklist and pause functions, proxy upgrades, supply. It does not watch price or liquidity yet. Up to three tokens per email, one confirmation email, and every alert has a one-click unsubscribe. We use your email for this and nothing else. A change is an observation of public on-chain data, not an accusation and not financial advice.
