BitGo Bank & Trust, N.A. (“BitGo Bank & Trust”), an OCC-regulated digital asset trust bank and subsidiary of BitGo Holdings, Inc. (NYSE: BTGO) (“BitGo”), today announced the availability of Aave, Spark, and Tesseract through its integration with Narval’s institutional DeFi gateway. The integration enables eligible institutional clients to access approved decentralized finance protocols directly from BitGo Bank & Trust qualified custody wallets, while maintaining institutional-grade security, governance, and policy-based approval controls.

BitGo’s integration with Narval is designed to help institutions participate in onchain financial markets without moving assets outside of their established BitGo qualified custody environment. Aave, Spark, and Tesseract are available today, with additional protocols in the future.

“Institutions want access to DeFi, but they need a path that meets their security, governance, and operational requirements,” said Mike Belshe, CEO and Co-founder of BitGo. “Our integration with Narval helps clients connect to approved DeFi protocols directly from BitGo custody, combining transaction verification and whitelisting controls with BitGo’s regulated custody infrastructure.”

"Our mission is to make onchain participation secure and seamless for institutions," said Greg Jessner, CEO and Co-Founder of Narval. "By integrating with BitGo's qualified custody, we're aiming to ensure that clients can access DeFi opportunities without compromising on compliance or security."

Narval's DeFi Gateway connects DeFi applications to BitGo's custody and wallet infrastructure through transaction integrity verification, delegated wallet connectivity, and an embedded dApp SDK. Before a transaction reaches the signing or custody approval workflow, Narval’s verification engine decodes transaction details into human-readable form and checks proposed interactions against approved protocols and contract addresses. These controls are designed to reduce blind-signing risk, support policy-based execution, and provide greater visibility into proposed protocol interactions.

Supported Protocols

Aave, Spark, and Tesseract are available at launch.

Aave is a decentralized liquidity protocol, enabling users to supply digital assets to earn rewards and borrow against their collateral through transparent, non-custodial markets. Through this integration, institutions can access Aave’s deep liquidity markets directly from BitGo qualified custody while maintaining their existing security, governance, and operational controls.

“Institutions can now access Aave lending markets directly through BitGo’s qualified custody environment, enabling greater participation in DeFi,” said Stani Kulechov, Founder of Aave Labs. “By combining BitGo’s regulated custody infrastructure, Narval’s secure connectivity layer, and Aave’s lending markets, this integration creates a stronger foundation for institutions to put digital assets to work, access liquidity, and move capital onchain at scale.”

Spark is an onchain savings and lending protocol designed to provide structured access to stablecoin and ETH-denominated credit markets through coordinated liquidity management and layered risk controls.

"Institutional capital requires more than access to rewards. It requires reliable access to liquidity, resilient risk structures, and infrastructure capable of operating under real market conditions," said Sam MacPherson, CEO of Spark. "This integration brings Spark’s onchain savings infrastructure directly into BitGo’s qualified custody environment, creating a more operationally secure pathway for institutions to access onchain credit markets."

Tesseract gives institutions regulated, professionally managed access to onchain earnings. Its Dedicated Client Vaults, built on Fusion by IPOR, are single-client, fully segregated mandates, each managed at Tesseract Investment Oy’s discretion under its MiCA authorization. Through this integration, BitGo clients can allocate to their vault directly from their custodial perimeter.

“Institutions have wanted to put their custodied capital to work onchain in a way their compliance teams can stand behind. With BitGo’s custody, Narval’s connectivity, and a vault we manage under our MiCA authorization, now they can,” said James Harris, CEO of Tesseract. “They allocate straight from their custodial perimeter via BitGo and can track the status and ownership securely from there.”

The integration marks another step in BitGo’s work to bring regulated custody infrastructure, institutional governance, and secure onchain connectivity together for the next phase of digital asset markets.
