About Chainitor

Chainitor is a blockchain monitoring and alerting service. You describe the on-chain condition you care about once — a treasury balance falling below a threshold, an ERC-20 transfer, a contract event, a change to a Safe multisig — and Chainitor watches for it and tells you when it happens.

Who operates it

Chainitor is operated by Totuma Labs, LLC, a Delaware limited liability company, registered at 1207 Delaware Ave #4311, Wilmington, DE 19806, United States. The same company runs its other work at totumalabs.com. Written questions of any kind — support, billing, privacy, security — go to [email protected]; see the contact page for what to include.

What the service does

Monitors run continuously against public blockchain data and fire an alert the moment a condition is met. The monitor types that exist today cover native balances, ERC-20 balances, transaction counts, emitted contract events, failed transactions, transaction values, function calls, and the configuration of Safe multisig wallets — owners added or removed, threshold changes, guard and module changes, and pending configuration changes.

Supported chains are Ethereum, Polygon, Arbitrum, Optimism, BNB Chain, Base, on both mainnet and their public testnets. Alerts are delivered over Email, Slack, Telegram, Webhooks, PagerDuty.

Plans, limits and check intervals are listed on the pricing section. A trial runs for seven days with no immediate charge.

Non-custodial by construction

Chainitor reads public chain data. It never asks for a private key or a seed phrase, it holds no funds, and it does not sign or send transactions on your behalf. Monitoring an address requires nothing from the owner of that address. Sign-in uses Google authentication or an emailed magic link, so no passwords are stored.

The service depends on third-party blockchain node providers, email delivery providers and cloud infrastructure, which is why the Terms & Conditions make no uptime or data-accuracy guarantee on the standard plans. Website analytics are self-hosted with Umami and set no cookies; the Privacy Policy sets out exactly what is collected.
