# Fungible Token (EIP-20 compatible)

> Recommended Hacken Extractor triggers for ERC-20 / EIP-20 fungible token contracts — monitor minting, transfers, and supply changes for exploits.

Implementations may have some differences, but all requirements of the [standard](https://eips.ethereum.org/EIPS/eip-20) must be met.

### Monitor the minting of new tokens

**Trigger:** Event Parameter *(coming soon)*

**Parameters:**

* **event:** Transfer
* **argument:** from
* **comparator:** equal to
* **value:** 0x0000000000000000000000000000000000000000

**Severity:** Critical

**Alerts:** On

**Use cases:**

* If your contract involves a one-time minting of the total supply, then minting new tokens after deployment signals an issue in the contract that has been exploited.
