EIP-7702 Transaction Relayer: OKX Core Wallet

On May 7, 2025, the Ethereum network completed the Pectra update, bringing with it a substantial enhancement for Externally Owned Accounts (EOAs). Thanks to EIP-7702 EOAs now possess polymorphic capabilities that allow them to function as if they were native smart contracts. This shift opens up an exciting new design space for EVM application developers.

This representative example uses a fork of the OKX Core Wallet to demonstrate how EIP-7702 transactions can be executed in 1Shot API simply by passing an authorizationList when calling execute. This example illustrates how developers can leverage the new features of EOAs to enhance user experience and streamline interactions with smart contracts.

A fork of the official Core-Wallet repository with 1Shot API-specific demonstrations can be found here.
