Nova V3 API and the New Data Engine

A common layer for wallet data

On May 31, 2026, we announced the Nova V3 API, our Hyperliquid integration, and a new data engine. I worked on this release as part of the effort to make Nova Wallet data more consistent across features. The visible product had expanded, but the larger change was underneath it. We needed one reliable way to collect, normalize, and present information from different sources.

The new data engine became that common layer. Instead of allowing each screen to interpret wallet information independently, we moved toward shared models for balances, positions, activity, and related account data. That work improved consistency inside the crypto wallet and reduced the chance that two parts of Nova would describe the same state differently. It also gave the Nova V3 API a clearer contract for the product surfaces built on top of it.

Hyperliquid integration was an important test of this approach. Trading information has different shapes and timing requirements from standard wallet balances. We integrated it through the same data discipline rather than creating a separate experience that felt disconnected from Nova. Users could see relevant Hyperliquid information in a context that matched the rest of the wallet.

For developers, the value was architectural clarity. The API defined how product features requested data, while the engine handled the work of making that data usable. For users, the improvement was simpler. Nova Wallet became faster to understand because related information appeared in a more consistent form. This release prepared the technical base for Nova V3 and for the trading and wallet tracking features that followed.
