ERC-20 token transfer alerts

Token alerts watch one ERC-20 contract and send a Telegram message when it moves. Follow every transfer of a token you hold, only the large ones, or only those to and from addresses you choose. Watch approvals too: an unlimited allowance is flagged as a drain risk the moment it is granted.

Coverage

What you can track

Any ERC-20 token

Stablecoins, governance tokens or a fresh launch: paste the contract address.

Large transfers only

A minimum amount in the token's units turns a busy token into a whale feed.

From and to conditions

Only transfers to or from the addresses you care about, such as a treasury or an exchange.

Approval alerts

Every Approval on the token, with unlimited allowances flagged as a drain risk.

Templates

Start an alert

Each template opens the add form with the rule filled in. Open one to pick a predefined address, or use your own.

How it works

One rule, from the address to the alert

Three steps: the address to watch, the rule that filters it, and the message you get.

01
USDC
Paste the contract address. Watching is read-only.

Good to know

What alerts include today

The limits, stated plainly. Anything marked coming soon is not live yet.

Amounts in the token's units

Thresholds and alerts use the token's own units (250,000 USDT), not USD. USD values are coming soon with Premium.

Approvals are watched per token

The approvals template watches one token contract. Approval risk across every token a wallet touches is coming soon with Premium.

Busy addresses use more events

An event is one transaction seen on one watched address. It counts once, whether it matches none, one or several of your rules and however many channels it fans out to. An alert is sent only when a rule matches. A heavily traded token such as USDT sees many transactions, so pick a paid plan for it; the dashboard estimates the monthly volume before you save.

Ethereum mainnet only

Alerts cover Ethereum mainnet today. More networks are coming soon.

FAQ

Frequently asked questions

Which tokens can I watch?

Any ERC-20 token on Ethereum mainnet. Paste its contract address and the template watches its Transfer (or Approval) events. There is no ABI or event signature to configure.

Can I get alerts only for large transfers?

Yes. Add a minimum amount in the token's own units, for example 1,000,000 USDT, and only transfers at or above it send an alert.

What does an approval alert show?

Who approved whom to spend how much of the token. When the allowance is unlimited, the alert adds a warning that the spender can move the whole balance.
