Solana Dev: Moving Scripts to Browser for a Functional Devnet Dashboard

After ten days of Solana development, the author successfully migrated their scripts to run entirely in the browser, creating a functional Devnet dashboard. The migration required handling RPC providers in a browser context, ensuring that the client can still communicate with Solana nodes over WebSocket or HTTP. BigInt data, which is common in Solana transactions, had to be rendered correctly in the UI, so the team added BigInt‑aware formatting and parsing logic. The dashboard displays real‑time account balances, transaction histories, and program logs, all fetched via the Solana JSON‑RPC API. The browser‑based approach reduces deployment complexity and allows users to interact with the dashboard without installing a full node. The project was built as part of the 100DaysOfSolana challenge and received support from Major League Hacking. The resulting prototype demonstrates that complex blockchain interactions can be handled client‑side with proper data handling. Future work includes adding wallet integration and more advanced analytics.
