Building a Frontend for a Rust-Based RISC-V Smart Contract on Polkadot: The Flipper Example

NOTE: This tutorial builds on top of a really nice post by Bader Youssef about writing RISC-V Rust contracts on Polkadot . Be sure to read it first beforehand! Hey folks, this is Husni, a software engineer with almost five years of experience in blockchain and full-stack development. I've spent most of my professional career diving deep into Polkadot's ecosystem, tinkering with everything from Substrate nodes to dApps. Recently, I got my hands on this neat little project: a Rust-based smart contract running on PolkaVM, which compiles to RISC-V for that bare-metal efficiency. The example is the classic "Flipper" contract, which toggles a boolean value, but pairing it with a frontend really brings it to life. The codebase is up on GitHub. After poking around the web and X for frontend tooling, I found that Parity and the Web3 Foundation haven't rolled out anything specific yet for these Rust-style contracts. So I leaned on Ethereum-compatible libs like wagmi and viem, leveraging Polkadot
