ArtistID

Artist identity on FHEVM. One wallet registers once, mints an ERC-721 identity and stores a profile - name, bio, portfolio URI, category - next to an encrypted reputation that only the holder and the contract can read.

How it fits together

• fhevm-hardhat-template/ - the ArtistID contract (ERC-721 + SepoliaConfig), the deploy scripts and the TypeChain bindings. Deployment metadata lives in deployments/<network>/.
• frontend/ - a Next.js 15 static export. The register, profile and verify pages talk to the contract through hooks/useArtistID.tsx; scripts/genabi.mjs turns the deployment JSON into the ABI and address map the app imports.

Reputation is an euint32 per token. addReputation/subReputation take an encrypted input handle plus its proof, and the result is clamped with an encrypted comparison so the value can never wrap. The artist counter is an encrypted aggregate.

Run it

cd fhevm-hardhat-template
npm install
npx hardhat compile
npm test

cd ../frontend
npm install
npm run genabi      # reads deployments/<network>/ArtistID.json + .chainId
npm run dev

genabi fails closed: a deployment without an ABI, or no deployment at all, is an error rather than a silent empty binding. next build runs it through prebuild.

Set NEXT_PUBLIC_PINATA_JWT per visitor - the frontend asks for a pinning token at upload time instead of shipping a shared one.
