Practical overview
When it fits
Use Faast when a browser-based portfolio and exchange interface, client-side transaction signing, or a documented wallet-extension starting point fits the task.
Who it is for
- People seeking a browser-based interface for cryptocurrency portfolio and exchange tasks.
- Developers exploring or adapting a React wallet application with client-side transaction handling.
- Developers extending currency support or hardware-wallet connection flows.
Documented uses
- Load cryptocurrency wallet balances.
- Create and sign transactions through client-side wallet code.
- Use a portfolio and exchange interface in a web application.
- Extend the application with another currency or hardware-wallet flow.
Requirements & limits
- The README describes private keys as remaining in the browser and being used to sign transactions.
- The application is built with React; the repository’s primary language is JavaScript.
- The project documents Ledger and Trezor hardware-wallet support.
- Adding a currency requires implementing its wallet behavior and updating related serialization, access, confirmation and explorer configuration.
Check current requirements in the official documentation. Source-based guidance does not mean OpenViST has run or independently tested this project.
