JavaScript Smart Contracts: A Practical Guide for Node.js Developers
· 10 min read
If you're a Node.js developer, the words "smart contract" probably make you think of Solidity, Remix IDE, Hardhat, gas optimization, and Ethereum test networks. That's the Web3 path — and it's powerful, but it's also a significant context switch from the JavaScript ecosystem you already know.
There's another path: JavaScript smart contracts on a permissioned blockchain. No new language to learn. No compilation step. No gas fees. No test networks. Just JavaScript — the language your team already writes every day.
Here's how to build, test, deploy, and upgrade smart contracts entirely within the Node.js ecosystem.
