This behavior is nonetheless conventional and does not conflict with the expectations of ERC20 applications. * Additionally, an `Approval` event is emitted on calls to `transferFrom`. This allows applications to reconstruct the allowance for all accounts just by listening to said events. Other implementations of the EIP may not emit these events, as it isn't required by the specification. * Finally, the non-standard `decreaseAllowance` and `increaseAllowance` functions have been added to mitigate the well-known issues around setting allowances.

This means\nthat a supply mechanism has to be added in a derived contract using `_mint`.\nFor a generic mechanism see `ERC20Mintable`.\n * *For a detailed writeup see our guide [How to implement supply\nmechanisms](https://forum.zeppelin.solutions/t/how-to-implement-erc20-supply-mechanisms/226).*\n * We have followed general OpenZeppelin guidelines: functions revert instead\nof returning `false` on failure. This behavior is nonetheless conventional\nand does not conflict with the expectations of ERC20 applications.\n * Additionally, an `Approval` event is emitted on calls to `transferFrom`.\nThis allows applications to reconstruct the allowance for all accounts just\nby listening to said events. Other implementations of the EIP may not emit\nthese events, as it isn't required by the specification.\n * Finally, the non-standard `decreaseAllowance` and `increaseAllowance`\nfunctions have been added to mitigate the well-known issues around setting\nallowances.

"details": "Implementation of the `IERC20` interface. * This implementation is agnostic to the way tokens are created. This means that a supply mechanism has to be added in a derived contract using `_mint`. For a generic mechanism see `ERC20Mintable`. * *For a detailed writeup see our guide [How to implement supply mechanisms](https://forum.zeppelin.solutions/t/how-to-implement-erc20-supply-mechanisms/226).* * We have followed general OpenZeppelin guidelines: functions revert instead of returning `false` on failure. This behavior is nonetheless conventional and does not conflict with the expectations of ERC20 applications. * Additionally, an `Approval` event is emitted on calls to `transferFrom`. This allows applications to reconstruct the allowance for all accounts just by listening to said events. Other implementations of the EIP may not emit these events, as it isn't required by the specification. * Finally, the non-standard `decreaseAllowance` and `increaseAllowance` functions have been added to mitigate the well-known issues around setting allowances.
