PasteBase

PasteBase is a decentralised pastebin service built on the Base blockchain. Think of it as a Web3 alternative to GitHub Gist: store code snippets, notes, or any text content, and it lives on-chain forever. Nobody can take it down, and nobody can change it.

Features

• Public pastes — share code or text with a permanent, shareable link
• Private pastes — wallet-based access control; only your wallet can read it
• Encrypted pastes — client-side encryption for sensitive content before it hits the chain
• Social layer — star pastes, comment, and tip creators with crypto
• User profiles — paste history tied to your wallet address

Tech stack

Next.js 13 with the App Router, React 18, TypeScript, and Tailwind CSS on the frontend. Smart contracts written in Solidity, deployed on Base and Base Sepolia. Web3 integration via wagmi v2 and viem, with support for MetaMask, WalletConnect, and most other wallets. Verified on Base Explorer.
