Introducing real-time balances with Turnkey

Today, Turnkey is launching real-time token balances for every address we secure, giving developers balance data, asset metadata, USD values, and transaction state through the same wallet infrastructure they already use for signing and transaction management.

Building a wallet application has always required more infrastructure than it should. Teams have had to secure keys in one place, fetch balances from another, wire up webhooks somewhere else, and maintain separate dependencies for token metadata, price data, and transaction status.

Turnkey is making that simpler. With Balances, applications can natively show users what they own, detect when deposits arrive, track when withdrawals settle, and reflect whether a transaction is pending, confirmed, finalized, or failed.

Turnkey’s wallet infrastructure now has real-time balances

Now supporting real-time token balances and balance webhooks across Ethereum, Base, Polygon, Arbitrum, and Solana, with more networks coming soon, Turnkey gives developers one platform for wallets, signing, transactions, and balance state.

This gives teams a way to fetch balances, display assets, detect deposits and withdrawals, and track transaction status without building their own indexing layer or relying on a separate balance provider.

One platform. One integration. 

Everything you need to build wallet balances into any product

Balance API

The Balance API returns real-time token balances with USD values and full asset metadata in a single API call.

That means teams can fetch the current state of a wallet and display it directly in their product, without stitching together separate calls for token prices, symbols, decimals, contract addresses, or logos.

Each supported asset includes the data developers need to build a complete wallet experience:

• Human-readable token balances
• USD-denominated values
• Token symbols
• Token decimals
• Contract addresses
• Token logos

For embedded wallet products, this removes one of the most common pieces of wallet infrastructure teams have historically had to build or buy elsewhere. Users can see what’s in their wallet, applications can surface balances accurately, and developers can spend less time maintaining balance infrastructure.

Webhook-driven wallet updates

Balances also includes webhooks, so applications can react to wallet activity without polling.

In addition to Turnkey’s activity webhooks, Turnkey is adding three new webhooks with Balances:

• Confirmed balance changes
  Fires when a balance change is detected onchain, allowing applications to update the user experience as soon as a deposit or withdrawal is observed.
• Finalized balance changes
  Fires when the balance change reaches finality, helping teams distinguish between detected activity and activity that has settled with stronger chain guarantees.
• Transaction status
  Tracks the full transaction lifecycle from submitted through confirmed to settled or failed, giving applications the state they need to update users, back-office systems, and operational workflows.

Together, these webhooks give teams a cleaner way to build reactive wallet experiences. A deposit can appear when it is detected. A withdrawal can move through pending and finalized states. A transaction can be tracked from submission through outcome without constant API polling.

Why real-time balances matter

Every wallet product needs a balance state. Without native balance infrastructure, teams have to secure keys in one place, fetch balances from another, subscribe to webhooks somewhere else, and manage transaction state through a separate pipeline.

That can create product drag. It also creates operational risk. When these components live in separate systems, teams have to reconcile state across multiple providers before they can give users a clear answer.

Balances brings that state into the same infrastructure that already secures wallets and signs transactions. The result is a more complete wallet stack, with fewer dependencies and clearer visibility across the full transaction lifecycle.

Turnkey: Building for complete wallet experiences

Real-time balances make Turnkey more complete across the product surfaces teams already use and are a natural extension of Turnkey’s infrastructure.

Turnkey already secures wallets, enforces signing policies, offers gas sponsorship, supports transaction management, and helps teams build production-grade onchain applications. 

Balance data is the next layer those applications need to function well.

Every layer above the RPC, from key management and signing through transaction broadcasting and now balance state, is built and operated in-house. That matters for reliability. It matters for roadmap speed. It matters for security boundaries. 

For developers, Turnkey offers one platform for wallets, signing, transactions, and balances.

For end users, it makes wallet experiences feel more complete. Assets can be displayed with the right metadata. Deposits can appear when detected. Transactions can move through clear status states. Applications can react without waiting on a manual refresh or background polling loop.
