Introducing Sovereign Card: Your Web3 Identity in One Link

What Is Sovereign Card?

Sovereign Card is the latest addition to the SVGN product suite. It is a Web3 identity card generator that turns your wallet into a shareable, visual profile page. Connect your wallet, and Sovereign Card automatically pulls your NFTs, token holdings, and recent on-chain activity into a beautifully designed card.

The live app is available at card.svgn.org.

Why We Built It

In Web3, your wallet is your identity. But sharing a raw 0x address tells people nothing about who you are or what you have accomplished on-chain. Sovereign Card bridges that gap by giving every wallet holder a human-readable, screenshot-ready identity page.

Whether you are a collector showcasing NFTs, a DeFi power user demonstrating portfolio depth, or a builder proving on-chain credibility, Sovereign Card makes your wallet story visible at a glance.

Key Features

Wallet Connect with 300+ Providers

Sovereign Card uses RainbowKit and wagmi to support MetaMask, WalletConnect, Coinbase Wallet, and hundreds of other wallet providers. Connection is seamless and requires only a single signature.

NFT Showcase Grid

Your NFT collection is displayed in a responsive grid with a detail modal for each item. Viewers can see collection name, token ID, and metadata without leaving your card.

Token Portfolio with USD Values

All token holdings are fetched via GoldRush (Covalent) APIs and displayed with real-time USD valuations. A 30-minute cache keeps the data fresh while conserving API credits.

On-Chain Activity Feed

Recent transactions are listed chronologically, including transfers, swaps, and contract interactions. Each entry links to the relevant block explorer for verification.

Custom Domain Binding (Pro)

Pro users can link their own domain to their Sovereign Card profile. The flow is simple: add the domain in Settings, create a CNAME record, and verify. Middleware handles the routing automatically.

One-Time Pro Upgrade

There are no subscriptions. Pay once via Stripe Checkout and unlock Pro features forever. The webhook-driven upgrade flow sets your account to Pro permanently.

Tech Stack

Sovereign Card is built with Next.js 14 App Router and TypeScript. The frontend uses Tailwind CSS with a dark cyber-aesthetic theme. Data is stored in Neon PostgreSQL, and on-chain data comes from the GoldRush API. Deployment runs on Vercel with custom domain support.
