Summary: EIP7702 allows setting (and changing) code on an externally owned account (EOA), effectively turning an EOA into a smart contract. One immediate benefit is gasless transactions via ERC4337’s paymaster infrastructure. In this post, I’ll explain how EIP7702 works and how to turn your EOA into an ERC4337 account.
EIP7702 is just around the corner with the Holesky testnet forking on Feb 24th UTC.
EIP7702 has many use cases.
Here I will outline one of the most obvious and demanded feature:
Gasless transactions from EOAs.
EIP7702 turns your EOA into a smart account that’s capable of sending gasless transactions**.**
I’ll show how an EOA can be turned into an ERC4337 account. I use ERC4337 here since it’s a battle tested standard with production ready implementations.
