Blockchain Monitors

Explore our comprehensive directory of real-time blockchain monitors. Track balances, smart contract events, and transaction activity across 7 supported networks.

Each monitor watches a public on-chain condition and sends an alert when it is met. Native and ERC-20 balance monitors cover treasuries and gas wallets. Transaction count monitors catch unusual activity. Event monitors watch a specific contract log. Safe wallet security monitors cover owner, threshold, guard, and module changes. Supported networks are Ethereum, Polygon, Arbitrum, Optimism, BNB Chain, Base, and Robinhood Chain — mainnet and their public testnets. Alerts go to email, Slack, Telegram, PagerDuty, or an HTTP webhook.
