Abstract

This paper presents a multisig Ethereum wallet that addresses two limitations of the standard externally owned account (EOA): the lack of multisignature authorization and the need for two separate transactions when depositing ERC-20 tokens. The proposed solution combines a multisig smart contract with the EIP-7702 code delegation mechanism, allowing a user to atomically approve and deposit funds in a single transaction. The work includes a demonstration of the system with real transactions on the Sepolia test network, confirming a gas saving of approximately 38% compared to the classic approach.
