Showcase · Vol. 01

Working demos, deployed live.

Two reference builds from the prompt library. Google sign-in via Privy; a fisher wallet pays gas so the user never sees a Sepolia ETH prompt.

EVVM · Fisher-signed payLive ↗

EVVM Pay

Sign an EVVM EIP-191 CSV message in the browser; the fisher route replays it on Sepolia and pays the gas. No wallet extension, no faucet.

zkVault · Shielded poolLive ↗

zkVault

Deposit, split and withdraw notes with Noir proofs generated in the browser (bb.js 4.2.0). The fisher submits the proof; the verifier lives on-chain.

EVVM × x402 · HTTP paywallLive ↗

EVVM x402

HTTP 402 challenge → EIP-191 signature → PAYMENT-RESPONSE settlement. Same wire protocol as @evvm/x402, self-hosted facilitator inside a TanStack API route.
