BitGo has opened access to Aave, Spark and Tesseract to eligible institutional customers through its integration with Narval.
The service links approved decentralized financial protocols to wallets held in BitGo Bank & Trust’s qualified custody environment.
The setup allows institutions to use onchain markets without transferring assets to wallets. BitGo said more protocols will be added to the service after launch.
BitGo links qualified custody to DeFi
Narval’s gateway links DeFi applications to BitGo’s custody and wallet systems. It uses delegated wallet connections and a built-in software kit to route approved transactions through signing and approval processes.
BitGo now integrates @Narvalgmi’s DeFi Gateway, giving institutional clients secure access to @Aave, @sparkdotfi, and @tesseractcrypto directly from qualified custody.
No blind signing. Full transaction verification. Institutional DeFi, well done.

Before BitGo receives a signing request, Narval converts the transaction into readable details. The authentication engine checks the protocol, contract address, and planned action in accordance with customer policy.
“Institutions want access to DeFi,” said Mike Belshe, CEO of BitGo.
Belshe said the integration combines transaction controls and whitelisting controls with BitGo’s OCC-regulated custody infrastructure. The checks are intended to reduce blind signing, where a user approves a transaction without seeing its terms.
Aave, Spark and Tesseract join the launch
Aave gives customers access to credit markets. Eligible institutions can supply assets or borrow against collateral while keeping their portfolio structure and approval rules within BitGo’s custodial framework.
Spark provides access to stablecoin and Ether-based savings and credit markets. The protocol uses coordinated liquidity management and layered risk controls to support credit and savings products.
Tesseract provides managed onchain revenue through segregated customer vaults built on Fusion by IPOR. According to the announcement, Tesseract Investment Oy will manage each mandate under its MiCA authorization.
Narval adds transaction checks before signing
Narval monitors interactions before they reach BitGo’s custody approval process. The system displays transaction information in readable form and compares the request against approved applications and smart contract addresses.
The gateway also supports policy-based execution. Institutions can create internal rules for which staff can use protocols, wallets, and actions before a transaction reaches the signer.
“Our mission is to make onchain participation secure and seamless for institutions,” said Greg Jessner, CEO of Narval.
The integration does not remove protocol, market or smart contract risk. It creates a layer of control between institutional wallets and the supported DeFi applications.
Institutional DeFi access continues to expand
The launch follows efforts to connect regulated or supervised custody systems with onchain markets. As crypto.news reported in May, MoonPay Trade introduced institutional access to Aave, Morpho and Maple across more than 200 networks.
Previous reports also covered OKX’s integration with BitGo’s off-exchange settlement service. This arrangement allows US institutional clients to trade on OKX while the assets remain in BitGo’s cold custody.
BitGo’s Narval integration applies a custody-first structure to DeFi. Customers can interact with approved protocols while maintaining BitGo’s management, transaction review, and wallet approval controls.
