TweetChain

Archive X (Twitter) posts to the ICP blockchain — permanently and privately.

Archive your important X (Twitter) posts directly onto the blockchain—permanently, immutably, and under your absolute ownership. TweetChain is a lightweight, decentralized, and self-custodial browser extension that allows creators, researchers, and Web3 enthusiasts to capture tweets, metadata, and visual proofs, preserving them forever on the Internet Computer (ICP) network. Why use TweetChain? • Permanent & Immutable: Once archived, your posts are stored on the decentralized ICP blockchain, safe from deletion, censorship, or platform changes. • Self-Custodial Security: Your identity is powered by a locally generated 12-word seed phrase.

Everything stays under your control. • Visual Proof: Capture high-quality local screenshots of tweets and secure them alongside the metadata as cryptographic proof of ownership. Features: • One-click scan and archive for x.com / twitter.com posts. • Complete metadata preservation (Tweet ID, text, timestamp, and author). • Local encrypted storage for your ICP identity. • Fully open-source and reviewable architecture with zero external/remote code execution.
