Qianzheqi worked on the aptos-labs/aptos-wallet-adapter repository, focusing on improving reliability for custom Aptos networks. During this period, they addressed a critical bug that caused crashes when submitting transactions on non-default networks by ensuring proper initialization of AptosConfig and accurate detection of network types. Their work involved deep integration with blockchain protocols and wallet development, using TypeScript to enhance the adapter’s stability. By resolving this initialization issue, Qianzheqi enabled broader support for custom networks and reduced transaction failures, contributing to a more robust developer experience. The work demonstrated focused problem-solving and a strong grasp of blockchain integration challenges.
