PolkaTruffle

PolkaTruffle is a specialized command‐line toolkit that simplifies Solidity smart‐contract development and deployment on Polkadot’s EVM‐compatible parachains—starting with Passet Hub Testnet (Chain ID 420 420 421). By packaging Truffle with preconfigured network settings, HDWalletProvider integration, and automatic npm‐dependency installation, PolkaTruffle removes all boilerplate and setup friction.

Key capabilities include:

• Instant Project Scaffolding:

  npx polkatruffle init

  Creates a complete Truffle project folder—contracts, migrations, tests, and a ready‐to‐go truffle-config.js pointed at Passet Hub Testnet—and immediately runs npm install inside it.

• Seamless Truffle Proxy:

  npx polkatruffle run

  Acts as a thin wrapper over npx truffle <…>, ensuring that every project uses the same bundled Truffle version and configuration.

• Blockscout Verification:

  npx polkatruffle verify  --network passetHubTestnet --apiKey

  Submits your compiled contract’s source code directly to Passet Hub’s Blockscout (via an Etherscan‐compatible API) to verify and publish on‐chain in one step.

• Multi‐Network Support:Although preconfigured for Passet Hub, the bundled truffle-config.js serves as a template—developers can quickly add other EVM parachains (Moonbeam, Astar, etc.) by copying and tweaking a few lines, making cross‐chain deployment trivial.

• Minimal Dependencies, No Docker:There’s no need to spin up containers or maintain local nodes. PolkaTruffle relies on the public Passet Hub RPC endpoint by default; teams can optionally connect to Ganache or any EVM provider for local testing.

Under the hood, PolkaTruffle leverages:

• Chalk for clear, colorized CLI feedback

• Yargs for robust command‐parsing and help screens

• HDWalletProvider (via environment variables) for seamless mnemonic or private‐key management

• Axios to communicate with Blockscout’s verification endpoints

By abstracting away network IDs, RPC URLs, provider setup, and verification payloads, PolkaTruffle reduces the barrier to entry for Solidity developers migrating to Polkadot’s EVM ecosystem. Whether you’re a solo builder wanting an out‐of‐the‐box “Hello, World!” flow on Passet Hub, or a full‐stack team integrating continuous‐deployment pipelines, PolkaTruffle delivers a turnkey experience: scaffold, install, compile, migrate, verify.

In short, PolkaTruffle turns what would normally be hours of configuration into a single npx command—so you can focus on writing, testing, and iterating on smart‐contract logic, without worrying about network IDs, gas settings, or block explorer APIs.
