From a technical perspective, WCT's cross-chain communication solution

#WalletConnect token ($WCT ) serves as the core governance and incentive tool of the Web3 communication protocol. Its technical architecture achieves efficient interconnection in a multi-chain ecosystem through modular design and decentralized mechanisms. Here are the core technical highlights of its cross-chain communication solution:

1. Chain-agnostic protocol and modular SDK

WalletConnect adopts a chain-agnostic architecture, compatible with mainstream blockchains like Ethereum, Solana, and Cosmos through standardized interfaces. Developers only need to integrate a single SDK to achieve multi-chain compatibility. Its modular design supports wallet connections, message relaying, push notifications, and other functions, significantly reducing multi-chain development costs.

2. Decentralized relay network and end-to-end encryption

The protocol relies on distributed relay nodes (such as the Waku network) to transmit cross-chain messages, avoiding single points of failure, and ensures data transmission privacy through end-to-end encryption (E2EE). For example, the Solana ecosystem achieves cross-chain synchronization with Ethereum through Wormhole's NTT framework, while $WCT acts as an incentive token to ensure node stability.

3. Account abstraction and future scalability

WalletConnect v2.0 has built-in account abstraction (AA) compatibility, supporting cross-chain interactions for smart contract wallets, and plans to integrate on-chain instant messaging (such as message transmission between encrypted wallets) to further expand application scenarios.

Challenges and outlook: Currently, the cross-chain efficiency of $WCT relies on the performance of relay nodes, and future optimization of latency issues is needed, but its technical framework has already provided a standardized model for the Web3 communication layer. @WalletConnect
