The popular USD-backed stablecoin [USDC v2](https://etherscan.io/token/0xa0b86991c6218b36c1d19d4a2e9eb0ce3606eb48) implements an expanded form of this spec. This can also be adopted alongside the [EIP-2612](./eip-2612) spec for maximum compatibility with existing applications.

## Motivation
There is an existing spec, [EIP-2612](./eip-2612), that also allows meta-transactions. The two primary differences between this spec and EIP-2612 are that:
There is an existing spec, [EIP-2612](./eip-2612.md), that also allows meta-transactions. The two primary differences between this spec and EIP-2612 are that:

- EIP-2612 relies on the ERC-20 `approve`/`transferFrom` ("ERC-20 allowance") pattern.
