Crypto Exchange: Eliminating On-Chain Fraud & Ensuring FATF Compliance
Industry: Cryptocurrency & Digital Assets
Client Overview: A leading crypto exchange faced mounting pressure from regulators regarding the FATF "Travel Rule" and was experiencing a rise in sophisticated fraud, including account takeovers and the use of synthetic identities. Their existing tools couldn't provide the on-chain visibility needed to mitigate these risks effectively.
Key Challenges:
- Inability to securely share required originator/beneficiary info between exchanges.
- High incidence of fraudulent sign-ups using stolen or fabricated identities.
- Lack of a single, trusted view of a user's identity across fiat and crypto transactions.
- Risk of being delisted or fined for non-compliance with global AML standards.
Our Solution:
We developed a consortium blockchain where participating exchanges could securely share encrypted KYC data via a standardized protocol. The solution utilized Zero-Knowledge Proofs to verify user information without revealing sensitive PII.
- Created a shared ledger for flagging fraudulent accounts and wallets across the network.
- Implemented ZKPs to allow the exchange to prove compliance without centralizing customer data.

Remittance Platform: Instant Cross-Border Verification
Industry: Payments & Remittance
Client Overview: A global remittance company needed to simplify identity verification for its users, many of whom were unbanked or underbanked and lacked traditional documentation. The process was manual, slow, and varied wildly by country, creating friction and high operational costs.
Key Challenges:
- Difficulty verifying identities from diverse, non-standardized international documents.
- Long delays in transaction processing due to pending KYC checks.
- High costs associated with using local, third-party verification agents in each country.
- User frustration leading to abandonment in favor of informal, unregulated channels.
Our Solution:
We built a public, permissioned blockchain on Ethereum that allowed trusted local partners (e.g., telcos, utility companies) to act as identity "attestors." These partners could issue Verifiable Credentials to users, which could then be used to instantly open an account on the remittance platform.
- Created a mobile-first SSI wallet for users to store and manage their credentials.
- Developed a smart contract-based system for rewarding attestors for valid verifications.
- Used the public blockchain for transparency and auditability of attestations.

Frequently Asked Questions
Traditional KYC databases are centralized, creating single points of failure and making them prime targets for data breaches. Blockchain creates a decentralized, tamper-proof record. Instead of storing user data, it stores cryptographic proofs of verification. This means you can confirm a user's identity without holding their sensitive data, drastically reducing your liability and enhancing security. It also enables a "verify once, use anywhere" model, which is impossible with siloed databases.
It depends on the use case. For a consortium of known financial institutions, a private, permissioned blockchain (like Hyperledger Fabric) is often ideal as it offers higher performance and control over participants. For creating a more open, universal identity system, a public but permissioned model on a platform like Ethereum can be more effective. We analyze your specific business goals, regulatory environment, and ecosystem to recommend the optimal architecture.
This is a critical design consideration. We solve this by never storing Personally Identifiable Information (PII) directly on the blockchain. Instead, we store PII in off-chain, encrypted data stores. The blockchain only holds cryptographic proofs and pointers to this data. If a user invokes their "right to be forgotten," the off-chain data can be permanently deleted, invalidating the on-chain pointers without altering the blockchain itself, thus satisfying both immutability and regulatory compliance.
A pilot or Proof of Concept (PoC) can typically be developed in 8-12 weeks. A full production-grade implementation with integration into existing systems can range from 4 to 9 months, depending on the complexity of your requirements, the number of integrations, and the scale of the deployment. We follow an agile methodology, delivering value in iterative sprints to ensure you see progress and can provide feedback throughout the process.
Our systems are designed for dynamic, real-world identities. When a user updates their information, they can get a new Verifiable Credential from a trusted issuer (e.g., a utility company for a new address). They can then present this new credential to services. The old credential can be revoked on-chain, providing a real-time, auditable history of changes while ensuring that only the most current, verified information is used for transactions.
