Kadena Workshop
summary
Kadena demonstrates a hands‑on Scaffold tutorial that spins up a local multi‑chain devkit (two simulated EVM chains), deploys Solidity contracts with Hardhat, connects a Next.js frontend and MetaMask, and moves the same contracts to testnet chain 20 where they are verified on the block explorer and interact live. Claims include a production Chainweb running for five years across 20 chains with linear scaling, native burn‑and‑mint bridging across Chainweb parallel chains, and a full deploy path in ~20 minutes.
