Wanchain operates as a decentralized ledger system facilitating cross-chain transactions and enabling interoperability among multiple blockchains. While serving as a bridge between different blockchains, Wanchain also functions independently as its own blockchain, operating autonomously and maintaining records of cross-chain transactions. Transactions on Wanchain extend beyond interactions among public blockchains to encompass exchanges with private chains. Derived from Ethereum (ETH), Wanchain inherits several features of the Ethereum blockchain. Through smart contracts, the protocol securely executes various applications. Use cases for Wanchain span decentralized exchanges (DEXs), lending and borrowing platforms, stablecoins, crowdfunding, multi-currency payments, and settlements. Wanchain operates in a fully decentralized manner, eliminating the need for custodial oversight or validation of transactions by third-party entities. Unlike some cross-chain systems that rely on third-party platforms for transaction authentication, Wanchain employs a locked account mechanism to secure and manage accounts on its network, minimizing external interventions.
