Generate zero-knowledge proofs on your device. Verify your identity privately without revealing personal data.
ZKProofport generates zero-knowledge proofs so you can demonstrate facts about your identity without directly disclosing the underlying sensitive information to the service requesting the proof.
The app is a proof generation and verification tool. It does not provide cryptocurrency buying, selling, swapping, trading, or transfers.
KEY FEATURES
On-Device Proof Generation
Proof computation runs locally on your device using Noir circuits and the mopro library. A remote proving server is not required.
Coinbase KYC Proof
Prove that you hold an existing Coinbase KYC attestation without directly disclosing your credential wallet address or KYC identity details to the requesting service. A wallet with an existing Coinbase attestation on Base is required. ZKProofport does not perform Coinbase's identity verification or provide access to Coinbase trading.
Coinbase Country Proof
Prove that the country in your Coinbase attestation satisfies a selected country-list inclusion or exclusion requirement, without directly disclosing your credential wallet address or identity documents to the requesting service.
OIDC Domain Proof
Generate a proof about your email domain using a supported Google or Microsoft sign-in, without directly disclosing your full email address to the requesting service. Available under Verify > Other > OIDC Domain.
Wallet Message Signing
Connect an existing external wallet through WalletConnect. For wallet-based proofs, approve a message signature to demonstrate control of your wallet. This does not authorize an asset transfer or execute a cryptocurrency transaction. Your private keys remain in your external wallet.
Proof Verification
Check proofs locally or with a read-only call to a deployed verifier contract. The app's contract verification does not submit a blockchain transaction or spend gas. A requesting service can independently verify the completed proof.
QR Codes and Deep Links
Open proof requests from compatible services through a QR code or deep link. Review the request, generate the proof on your device, and return the completed proof to the requesting service through the relay.
Proof History and Display Settings
Review and manage saved proof records, and choose a light or dark theme.
HOW IT WORKS
1. Open Verify, or open a proof request from a compatible service.
2. Review the selected proof and its requirements.
3. For Coinbase proofs, connect a wallet with the required attestation and approve a message signature. For OIDC proofs, use the supported sign-in flow.
4. Generate the zero-knowledge proof locally on your device.
5. Inspect or verify the result, and return it to the requesting service when applicable.
PRIVACY AND NETWORK USE
Zero-knowledge proofs let a service verify the requested fact without receiving the underlying private proof inputs. The app still uses network connections for external wallet communication, supported identity sign-in, public attestation queries, circuit downloads, and proof delivery or verification. A completed proof includes the public inputs required for verification.
The app requests camera access when you use the QR scanner.
