What's live, what's next
Everything Alerts on Chain does today, what we are building next and the ideas we are exploring. No dates: an item moves to “Live now” when it ships.
Live now
Works today, on Ethereum mainnet.
Wallets
Wallet movements
Alerts on ETH, ERC-20 and NFT transfers in or out of any address, filtered by direction, type, asset and counterparty.
Amount thresholds
Minimum and maximum amounts in the asset's own units (no USD), for one asset or ETH.
NFTs
NFT mints, burns, transfers and sales
Mints, burns and transfers on an ERC-721 or ERC-1155 collection, and Seaport sales (without the sale price).
Tokens, DeFi and smart contracts
Token transfers
Every Transfer of an ERC-20 token, optionally only above an amount or to/from chosen addresses.
Token approvals
Approvals granted on a token, with unlimited allowances flagged as a drain risk.
DEX swaps

Lending activity

DAO governance

Method calls
Direct calls to a contract's functions: any method, or one you name by pasting its signature, with conditions on arguments by name, caller, ETH value and status.
Contract events
Specific events from the standard catalog, the events listed for a well-known contract, or a pasted event signature, with conditions on any argument by name.
Everything on a contract
Every log a contract emits, with no event to pick. Each match counts toward the plan's monthly events, like any other alert.
Channels
Telegram delivery
Alerts in a Telegram DM or group within seconds, one message per transaction per rule, named after the rule.
