Space and Time Adds USDC Payments to Power ZK Coprocessing at Scale

San Francisco, CA – Space and Time, the blockchain purpose-built for zero-knowledge (ZK) proven data, is expanding its reach with the integration of USDC as a payment option for ZK coprocessing. Developers can now use the world’s most trusted stablecoin to pay for verifiable compute workloads on the Space and Time network, simplifying access to next-generation infrastructure for building onchain apps.

Why It Matters

Backed by Microsoft’s M12 and Circle Ventures, Space and Time is designed to prove SQL queries across millions of rows of data in sub-seconds through its breakthrough technology, Proof of SQL.

By combining blockchain security with verifiable data from onchain and offchain sources, Space and Time enables developers to build applications that require trusted, real-time data—from DeFi and onchain gaming to sophisticated financial contracts.

Now, with USDC integrated as a native payment method, developers can fund workloads using a widely adopted digital dollar that holds stable value. Payments are automatically converted into SXT, the network’s native token, for seamless use within the protocol.

“Enabling USDC payments on Space and Time is a huge milestone for the SXT ecosystem. We’re empowering developers to build secure, expressive applications onchain with the industry’s first sub-second ZK coprocessor. USDC integration makes it smoother and more efficient to scale those apps.”

Scott Dykstra, Co-Founder of Space and Time

Brian Schultz, Vice President of Corporate Development at Circle Ventures, added:

“We’re excited to see USDC live on Space and Time, a platform advancing the frontier of zero-knowledge infrastructure. At Circle Ventures, we support technologies that make digital assets more usable, programmable, and trusted across Web3—and this is a strong step in that direction.”

Building Verifiable, Data-Driven Apps

The integration builds on Space and Time’s recent mainnet launch, marking the next phase in scaling access to high-performance ZK infrastructure.

Known as the blockchain for ZK-proven data, Space and Time allows smart contracts to securely compute over information from any chain or source. Its Proof of SQL coprocessor delivers sub-second verification, empowering developers to build more intelligent, data-rich applications that rely on trusted inputs.

Adding USDC—a fully reserved, regulated digital dollar issued through Circle’s licensed affiliates—further lowers barriers for builders. USDC runs across leading blockchain networks and has become the preferred stablecoin for near-instant, low-cost global payments. 

With this integration, developers can leverage both the stability of USDC and the advanced compute of Space and Time, creating a smoother bridge between real-world finance and onchain applications.

Bottom Line

By pairing Space and Time’s verifiable compute with USDC’s stability and global adoption, developers gain an easier, more reliable way to build powerful onchain applications. Whether in DeFi, gaming, or enterprise use cases, the integration represents a step toward making ZK infrastructure—and the tokenized economy it supports—usable at scale.
