This set of interfaces, contracts, and utilities are all related to the [ERC20 token standard](https://eips.ethereum.org/EIPS/eip-20).
|
|
|
|
*For a walkthrough on how to create an ERC20 token read our [ERC20 guide](../../learn-about-tokens.md#constructing-a-nice-erc20-token).*
|
|
|
|
There a few core contracts that implement the behavior specified in the EIP: `IERC20`, `ERC20`, `ERC20Detailed`.
|
|
|
|
Additionally there are multiple extensions, including:
|
|
- designation of addresses that can create token supply (`ERC20Mintable`), with an optional maximum cap (`ERC20Capped`),
|
|
- destruction of own tokens (`ERC20Burnable`),
|
|
- designation of addresses that can pause token operations for all users (`ERC20Pausable`).
|
|
|
|
Finally, there are some utilities to interact with ERC20 contracts in various ways.
|
|
- `SafeERC20` is a wrapper around the interface that eliminates the need to handle boolean return values.
|
|
- `TokenTimelock` can hold tokens for a beneficiary until a specified time.
