During May 2025, Hieu Vo developed a unified RPC-based pool state retrieval feature for the KyberNetwork/kyberswap-dex-lib repository. He introduced the FetchRPCData method in Go, enabling the tick-based DEX pool tracker to retrieve pool state directly from RPC endpoints. By refactoring data access to standardize on RPC-derived information, Hieu improved the reliability and consistency of pool state data across different DEX implementations. This backend development work enhanced cross-DEX compatibility and analytics readiness, providing a single, dependable data source for business decisions. His contributions focused on blockchain integration, smart contract interaction, and maintainable backend architecture within the Go ecosystem.
