SBI and Megabanks Successfully Test Regulated, KYC-Compliant Liquidity Pools
SBI VC Trade has released the results of a pioneering proof-of-concept (PoC) aimed at bringing institutional-grade compliance to Decentralized Finance (DeFi).
The experiment, conducted under the auspices of the Financial Services Agency’s (FSA) "FinTech Proof-of-Concept Hub," marks a significant step toward a "permissioned" DeFi ecosystem where regulated financial institutions can participate in Automated Market Makers (AMMs) without sacrificing Anti-Money Laundering (AML) standards.
Key participants in the "DeFi Study Group" included a "who’s who" of Japanese finance, including Sony Bank, Daiwa Securities, Nomura Holdings, bitbank, Mizuho Trust & Banking, Sumitomo Mitsui Trust Bank, and Mitsubishi UFJ Trust and Banking.
The "Permissioned" DeFi Model
Current DeFi protocols typically operate in a "permissionless" environment, making it difficult for regulated banks to meet Know-Your-Customer (KYC) and AML requirements. The SBI-led experiment sought to solve this by creating a "Specific AMM"—a protocol that remains immutable on the blockchain but restricts access through a sophisticated token-gating system.
Technical Breakthroughs in Compliance
The PoC successfully verified a five-step procedure designed to keep bad actors out of the liquidity pool:
- Institution Registration: Financial institutions register their addresses on a master smart contract.
- AMM Authentication: These institutions issue "Authentication Tokens" to specific AMMs that meet regulatory criteria.
- Customer KYC Gating: Institutions perform KYC on clients and issue a "KYC Token" to the user's wallet.
- Transfer-Restricted Assets: Issuers send tokens (mimicking crypto-assets or securities) that can only be moved between KYC-verified addresses.
- Regulated Trading: Only users holding valid KYC tokens can interact with the authenticated AMM to provide liquidity or swap assets.
Crucially, the experiment confirmed that financial institutions maintain "kill-switch" capabilities. If a user’s risk profile changes or their KYC expires, the institution can invalidate the KYC token, instantly cutting off that user's ability to trade or withdraw within the specific AMM.
The Regulatory Verdict
The FSA provided critical feedback during the process. While the agency noted that developing an immutable AMM using test tokens does not currently constitute a "crypto-asset exchange business," it warned that deploying such protocols for real-world assets may fall under existing regulations.
However, the FSA spoke favorably of the risk-mitigation measures, noting that using KYC tokens with expiration dates and the ability to invalidate them in high-risk scenarios aligns with national AML/CFT guidelines.
The Road Ahead: Legal Grey Areas
Despite the technical success, the report highlights several "unresolved legal points" that the industry must navigate before a commercial rollout:
- Whether "swapping" on an AMM constitutes a legal "sale or exchange" of securities or crypto-assets.
- The legal status of developers who provide user interfaces for these protocols.
- The extent to which banks can legally participate in the management of liquidity pools.
Conclusion
As Japan continues to position itself as a hub for regulated digital asset innovation, this experiment provides a blueprint for how the "Wild West" of DeFi can be tamed for institutional use. SBI VC Trade and its partners indicated they will continue to collaborate with regulators to build a robust ecosystem for "Regulated DeFi," focusing on the business potential of transfer-restricted tokens.
