During this period, contributed to blockchain integration by delivering two key features across the smartcontractkit/chainlink and smartcontractkit/chainlink-protos repositories. Developed cross-chain support for the TON Network by updating Protocol Buffers definitions and build configurations, enabling TON as a recognized chain type. Implemented TON keystore and key management functionality in Go, allowing creation, import, export, and deletion of TON keys, and introduced new interfaces and commands for interacting with the TON blockchain. These enhancements improved the Chainlink keystore service’s developer productivity and security for TON operations, demonstrating depth in Go programming, blockchain development, and gRPC-based service design.
