Building a Crowdfunding dApp with ink! Smart Contracts and PAPI/ReactiveDOT
The tutorial walks you through building InkFundMe, a decentralized crowdfunding dApp using ink! smart contracts (for a PSP22 token and campaign logic) and a React frontend powered by PAPI (Polkadot API) and ReactiveDOT. Users can create campaigns, contribute with tokens, and claim refunds if goals aren’t met. It covers contract architecture, security best practices, deployment to the Passet Hub testnet, frontend integration, and optional Vercel deployment, resulting in a fully functional, secure, and customizable crowdfunding platform on Polkadot.
