BitGo opens Aave, Spark and Tesseract DeFi access to institutions

BitGo has opened access to Aave, Spark and Tesseract for eligible institutional clients through its integration with Narval.

The service connects approved decentralized finance protocols to wallets held within 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 join the service after launch.

BitGo connects qualified custody to DeFi

Narval’s gateway links DeFi applications to BitGo’s custody and wallet systems. It uses delegated wallet connections and an embedded 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.

Zero blind signing. Full transaction verification. Institutional DeFi, done right.

Before BitGo receives a signing request, Narval converts the transaction into readable details. Its verification engine checks the protocol, contract address and planned action against client policies.

“Institutions want access to DeFi,” BitGo chief executive Mike Belshe said.

Belshe said the integration combines transaction checks and whitelisting controls with BitGo’s OCC-regulated custody infrastructure. The controls aim to reduce blind signing, where a user approves a transaction without seeing its terms.

Aave, Spark and Tesseract join at launch

Aave gives clients access to lending markets. Eligible institutions can supply assets or borrow against collateral while keeping their wallet structure and approval rules inside BitGo’s custody 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 lending and savings products.

Tesseract offers managed onchain earnings through segregated client vaults built on Fusion by IPOR. Tesseract Investment Oy manages each mandate under its MiCA authorization, according to the announcement.

Narval adds transaction checks before signing

Narval checks interactions before they reach BitGo’s custody approval process. The system displays transaction information in readable form and compares the request with approved applications and smart-contract addresses.

The gateway also supports policy-based execution. Institutions can set internal rules for which protocols, wallets and actions staff may use before a transaction reaches the signer.

“Our mission is to make onchain participation secure and seamless for institutions,” Narval chief executive Greg Jessner said.

The integration does not remove protocol, market or smart-contract risk. It creates a control layer between institutional wallets and the supported DeFi applications.

Institutional DeFi access continues to expand

The launch follows efforts to connect regulated or controlled 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.

Earlier reporting also covered OKX’s integration with BitGo’s off-exchange settlement service. That arrangement lets U.S. institutional clients trade on OKX while assets remain in BitGo cold custody.

BitGo’s Narval integration applies a custody-first structure to DeFi. Clients can interact with approved protocols while retaining BitGo’s governance, transaction review and wallet approval controls.
