Sovereign Card — Web3 Identity Card - The business card of the on-chain era.

Your wallet has a rich on-chain story. Sovereign Card turns it into a beautiful, shareable identity page. NFTs · Token portfolio · Activity feed — all in one link. No email, no password. → Pay once for Pro, own it forever → Custom domain support → Open source · MIT

Hey Product Hunt! 👋 I'm lyuansen, an indie dev who's been building Web3-native tools under the Sovereign brand. I built Sovereign Card because I kept running into the same problem: crypto wallets have rich on-chain history, but there's no clean way to show it off. Your ENS is just an address. Your NFT collection is buried in OpenSea. Your DeFi activity is a wall of Etherscan hex. Sovereign Card fixes that — connect your wallet, get a shareable identity page with your NFTs, tokens, and activity, all in one link. A few things I'm proud of: - **No email, no password** — wallet address is your identity - **One-time Pro upgrade** — pay once, link your own domain, done. No subscription guilt. - **30-min cache** — keeps it fast without hammering API rate limits - **Open source** — MIT, fork it and build on it Would love your feedback, especially around: 1. Which chains should I add support for next? (currently EVM) 2. What else should be on the card? (POAPs? DAO memberships?) Thanks for checking it out. Happy to answer any questions below 🙏
