In April 2025, Jae Kim developed the WalletSendCalls feature for the xmtp/xmtp-js repository, enabling users to initiate and manage on-chain transaction requests directly within XMTP messages. Leveraging JavaScript, TypeScript, and React, Jae integrated Wagmi to handle transaction initiation, chain switching, and the serial execution of multiple smart contract calls. The implementation included surfacing transaction details with explorer links for enhanced visibility and auditing. This work addressed the need for seamless, in-message transaction workflows in Web3 applications. Over the month, Jae focused on feature development without major regressions, demonstrating depth in frontend and smart contract integration within decentralized messaging.
