SEDAX: How Metaborong Built a Blockchain eKYC Platform with Zero-Knowledge Proof Identity Verification
By Metaborong, development partner·Published June 2026
SEDAX is a blockchain eKYC platform that verifies identity with Zero-Knowledge Proofs, so users prove who they are without sharing the underlying personal data.
Built from the ground up by Metaborong as development partner on self-sovereign identity and W3C Verifiable Credentials. SEDAX replaces centralized document collection with privacy-first, reusable verification.
What Metaborong Built
Metaborong engineered SEDAX as a blockchain-native identity infrastructure on three foundational layers: Zero-Knowledge Proof verification, where claims are validated cryptographically without revealing the raw data; self-sovereign identity, where users hold their own credentials and share only what each request needs; and a blockchain trust ledger, where issuance, verification, and revocation are recorded on a tamper-evident, decentralized layer independent of any central authority.
Zero-Knowledge Proof Verification
In a traditional KYC system a user shares a date of birth and the verifier stores it indefinitely. In SEDAX, a user proves they are over 18 and the verifier receives only a cryptographic confirmation: no date of birth is ever transmitted or stored. Metaborong engineered this verification across age, nationality and jurisdiction claims, professional credentials, financial eligibility, and biometric liveness, one party proving a statement is true without revealing anything beyond the truth of the statement itself.
Self-Sovereign Identity and Verifiable Credentials
Self-sovereign identity gives individuals, not corporations or governments, control over their own identity data. Rather than submitting documents to a third-party processor, users hold W3C Verifiable Credentials in a personal wallet and present only the credentials each interaction needs. SEDAX credentials are interoperable with other SSI-compliant systems, cryptographically signed by the issuer, verifiable without contacting the issuer, and support on-chain revocation without revealing user data.
On-Chain Trust and Reusable KYC
Credential issuance, verification events, and revocation are recorded on a tamper-evident blockchain ledger, creating an auditable trust layer no central authority controls. Because a verified credential is portable, one verification event can be reused across multiple services instead of repeating full document submission. On-chain audit trails, revocation for AML watchlist management, and structured verification logs give regulated institutions the accountability KYC/AML compliance requires.
AI-Assisted Fraud Detection
Alongside the ZKP layer, SEDAX integrates AI-assisted fraud detection. Document-authenticity analysis flags forged or manipulated identity documents, biometric liveness detection prevents photo, video-replay, and deepfake spoofing during onboarding, and behavioral risk scoring flags anomalous verification patterns. These checks reduce identity fraud without adding friction for legitimate users.
Technical Approach
SEDAX verifies identity across three layers: claims held in a user-controlled wallet as W3C Verifiable Credentials, a Zero-Knowledge Proof core that confirms a claim without transmitting the underlying data, and a tamper-evident ledger recording issuance, verification, and revocation, with AI-assisted liveness and document checks guarding onboarding.

Results & Impact
Metaborong delivered a production-ready, privacy-first identity infrastructure for SEDAX in 2026.
- Live in production. SEDAX runs at sedax.in, a privacy-first blockchain eKYC platform.
- Engineered ground-up by Metaborong as development partner. The Zero-Knowledge Proof verification core, self-sovereign identity wallet, on-chain trust ledger, and AI fraud-detection layer were built from the ground up.
- Raw personal-data exposure during verification is reduced by design, since proofs confirm claims without transmitting the underlying data.
- Users control which credentials are shared with which verifiers, replacing blanket document submission with selective disclosure.
- Centralized identity storage as a single point of failure is eliminated, since credentials live in user-controlled wallets.
- Reusable KYC lets one verification event work across multiple services instead of repeating full document checks.
- Privacy compliance is structural, with alignment to GDPR and India's DPDP Act consent and data-minimization requirements.
Frequently asked questions
Zero-Knowledge Proof is a cryptographic method that lets one party prove a statement is true without revealing any additional information. In identity verification, ZKP lets a user confirm they meet a requirement without sharing their underlying identity document or personal data.
Self-sovereign identity is a digital identity model where individuals hold and control their own credentials in a personal wallet rather than relying on centralized identity providers, selectively sharing only the specific credentials each interaction needs.
Verifiable Credentials are a W3C standard for digitally signed, cryptographically verifiable identity claims issued by trusted authorities and presented to verifiers without contacting the original issuer, forming the basis of interoperable, portable digital identity.
SEDAX generates on-chain audit trails for all verification events, supports credential revocation for AML list management, and integrates AI-assisted fraud and liveness detection, providing the regulatory accountability KYC/AML compliance requires in regulated industries.
Yes. SEDAX's ZKP architecture lets Aadhaar-linked claims be verified without transmitting raw Aadhaar numbers, aligning directly with India's DPDP Act consent and data-minimization requirements.
Reusable KYC lets a user who has completed identity verification once reuse that verified credential across multiple services without repeating the full document submission, enabled by SEDAX's verifiable credential architecture.
