ERC2612

• Permit extension for ERC20
• From the Github (25-4-2020):

"A function permit extending ERC-20 which allows for approvals to be made via secp256k1 signatures. This kind of "account abstraction for ERC-20" brings about two main benefits:

• transactions involving ERC-20 operations can be paid using the token itself rather than ETH,
• approve and pull operations can happen in a single transaction instead of two consecutive transactions,

while adding as little as possible over the existing ERC-20 standard."
