Engineering Architecture & Implementation
Creating a seamless user experience inside messaging apps usually requires trusting a centralized custodian with user funds. Vext developed a client-side WebAssembly module that generates and signs transactions inside the user’s sandboxed mobile browser environment without ever sharing the private key with Telegram or backend servers.
