# EIP2612 Signed token approvals **This doc is a sum up of EIP 2612 and an overview of Permits** ### Intro Approve the message to allow dApp to spend a token. This is a human-readable signature instead of normal signatures, which are just a bunch of binary data (readable by computers). > 712 can be used without 2612\ > 712 defines a format for signatures\ > 2612 defines a smart contract interface ## Simple explanation ELI5 explanation:\ Permits are permissions that send the approved TX to allow dApp to use/spend your tokens.\ Example: Uniswap asks you to use DAI in order to swap DAI for some other token. ## Functions This ERC proposes an alternative solution that is designed to be as minimal as possible and to only address *one problem*: the lack of abstraction in the ERC-20 `approve` method. While it may be tempting to introduce `*_by_signature` counterparts for every ERC-20 function, they are intentionally left out of this ERC-20 for two reasons: * the desired specifics of such functions, such as decision regarding fees for `transfer_by_signature`, possible batching algorithms, varies depending on the use case, and, * they can be implemented using a combination of `permit` and additional helper contracts without loss of generality.
