Multi-Chain Smart Wallet With Gasless Transaction

Abstract

Blockchain technology is advancing at a rapid pace, but two major obstacles still stand between mainstream adoption: the insufficiency of interoperability between various blockchain networks and the prohibitively high gas charges. The above concerns are solved by this paper using a secure multichain smart wallet architecture with gasless transaction support and cross-chain communication. The system employs threshold cryptography for secure management of keys in a decentralized manner, is coupled with the Gas Station Network (GSN) to hide fees from users, and supports various blockchain networks such as Ethereum and Solana. The system has been thoroughly analyzed and validated using real-life scenarios. we achieved a transaction efficiency of 99.77% with 100% successful completion of transactions in 53 test transactions. The design achieves greater security using advanced cryptographic techniques while staying users accessible and preventing economic hurdles towards blockchain adoption.
