SMBC Nikko Securities, Nethermind Ink Deal with Uniswap Labs, Base for Japan DeFi Gateway

SMBC Nikko Securities and Nethermind have signed a memorandum of understanding with Uniswap Labs, Base, and Nyx Foundation to establish a Japan-focused Decentralized Finance (DeFi) Gateway. This initiative aims to provide eligible investors in Japan with regulated access to decentralized financial products.

The project, slated for completion by mid-2027, will utilize Uniswap v4 hooks to integrate compliance measures, including anti-money laundering (AML) and counter-financing of terrorism (CFT) protocols, directly into liquidity pools. This approach is designed to create a liquidity-provisioning protocol featuring custom pools built to meet specific regulatory requirements.

Under the agreement, SMBC Nikko Securities will spearhead regulatory engagement and provide compliance expertise. Nethermind will manage the technical development, encompassing AI and smart-contract security. Uniswap Labs will contribute its protocol and v4 hook architecture, while Base, the blockchain operated by Coinbase Technologies, will serve as the underlying infrastructure.

SMBC Nikko Securities established its DeFi Technology Department in February 2026, signaling a strategic commitment to the sector ahead of the October 2, 2026, memorandum of understanding signing. The collaborating entities plan to provide regular updates to Japan’s Financial Services Agency (FSA).

The venture’s success hinges on several critical factors: the security of smart contracts, the effective operation of AI and compliance tools, and the FSA’s ongoing acceptance of the developing framework. This collaboration represents a significant step by a traditional securities firm to integrate DeFi into Japan’s regulated financial landscape by building upon existing decentralized infrastructure.
