Tempo is bringing a new performance frontier to the world of onchain payments. With 100,000+ TPS, sub-second finality, and a unique architecture designed for payments, it is the natural home for the next generation of financial apps. 

Regardless of how those apps would look, users and builders alike need reliable wallet data—positions and transaction history—delivered instantly.

That’s where Zerion comes in. We are excited to support Tempo’s testnet, providing both a consumer-ready wallet interface and the data infrastructure for developers.

Zerion Wallet: The best way to track Tempo assets

Anyone can now use Zerion Wallet to have full visibility into their Tempo testnet portfolio and transactions.

Because Tempo is designed specifically for stablecoin utility, tracking your positions accurately is critical. Zerion Wallet will automatically display:

  • Real-time portfolios: View all your token balances on Tempo alongside your assets on other chains. 
  • Transaction history: Clear, human-readable transaction history for every payment sent or received.
  • Unified balance: Once the mainnet launch, you’ll be able to see your net worth across all chains, with Tempo fully integrated into the global portfolio view.

Even more importantly, app builders can access this wallet data via Zerion API. 

Zerion API: The fastest way to get Tempo wallet data

For developers building payment processors, wallets, or financial tools on Tempo, access to clean data is a major bottleneck. Running your own indexers for a high-throughput chain like Tempo (capable of 100k TPS) is expensive and complex.

Zerion API solves this. It is an enterprise-grade wallet data API that gives you instant, fully interpreted wallet data on Tempo without running your own infrastructure. 

Builders can use Zerion API to fetch wallet data for any Tempo address:

  • Positions: Get accurate balances for any address on Tempo in sub-seconds.
  • Portfolio balance: Get a portfolio balance chart, making it easy to create visualizations. 
  • Transactions: Retrieve parsed history for reporting, tax compliance, and analytics.

Additionally, Zerion API provides webhooks, which enable builders to subscribe to all new transactions to specified Tempo addresses. This is particularly useful for creating real-time notifications.

Finally, Zerion’s Tempo data uses the same schema that’s used for EVM and Solana, potentially saving months of integration time when building across several chains.

Zerion API helps Tempo developers to ship faster and focus on what matters: building the future of payments.

Build on Tempo Faster

Tempo’s speed and stablecoin-native gas model unlock use cases that were previously impossible onchain. Yet those experiences depend on world-class wallet data that is just as fast.
