ZK proof generation for Coinbase KYC, country verification, OIDC domain verification, and GIWA attestations with optional action authorization. Provable circuits: coinbase_attestation, coinbase_country_attestation, oidc_domain_attestation, giwa_attestation. Noir circuits execute in the ZKProofport prover. Configured x402 USDC payment networks: base (eip155:8453), ethereum (eip155:1). See /identity/status for verified ERC-8004 registrations.

Skills

• Generate ZK Proof
  [SINGLE-STEP x402] Generate a zero-knowledge proof via x402 single-step flow in the ZKProofport prover. Read the payment requirements returned by the service for the selected payment scheme. SUPPORTED CIRCUITS: coinbase_attestation, coinbase_country_attestation, oidc_domain_attestation, giwa_attestation - coinbase_kyc: Prove Coinbase KYC verification without revealing identity. EAS schema 0xf8b05c79f090979bf4a80270aba232dff11a10d9ca55c4f88de95317970f0de9. - coinbase_country: Prove country of residence with inclusion/exclusion list. EAS schema 0x1801901fabd0e6189356b4fb52bb0ab855276d84f7ec140839fbd1f6801ca065. REQUIRED INPUTS: Inputs are circuit-specific. Read /api/v1/guide/{circuit} and prepare them with the client SDK. Coinbase circuits use wallet/attestation witnesses. giwa_attestation supports optional EIP-712 action binding: provide both domain_separator and action_hash for a signed action, or omit both for an identity-only proof. GIWA uses its own configured attester. OIDC domain verification uses its OIDC witness. PAYMENT: $0.10 USDC. Configured networks: base (eip155:8453), ethereum (eip155:1). Read the returned x402 offers. RETURNS: proof (hex), publicInputs (hex), proofWithInputs (hex for on-chain verification). No hardware TEE attestation is advertised ON-CHAIN VERIFICATION: - Verifier contracts on Ethereum Mainnet (chainId=1): coinbase_attestation=0xf3d5a09d2c85b28c52ef2905c1be3a852b609d0c, coinbase_country_attestation=0x78792554e1582cb49d858eacb5c3607b42d28224, oidc_domain_attestation=0x440eaa25603ed5480cad0ee51d9808a1993ef267, giwa_attestation=(no verifier on this chain) - Call verifier.verify(proofWithInputs) to verify on-chain
