Building the Settlement Layer for the Agentic Future
QDay is a post-quantum, EVM-compatible network built for the next generation of decentralized applications, autonomous agents, and programmable payments.
QDay provides fast, low-cost infrastructure for applications that need frequent, programmable onchain transactions. It is EVM-compatible today and designed for sub-second settlement at mainnet, with SDKs, APIs and agent-ready payment capabilities on the way — built for both human and machine-driven commerce.
As onchain activity becomes more automated, the infrastructure has to solve two problems at once: it must be fast and programmable enough for agents and frequent payments, while preparing for the long-term risks of quantum computing. QDay brings these requirements together in one EVM-compatible network.
Post-Quantum EVM Infrastructure for the Agentic Economy
Why QDay Exists
The internet is becoming increasingly machine-driven. Agents are moving from generating information to taking actions, while stablecoins and programmable payments are becoming practical rails for digital commerce.
At the same time, the cryptography securing today's networks was not designed for a post-quantum world. QDay is built to address both shifts: a fast, EVM-compatible network for applications and payments, with a long-term commitment to quantum-resistant infrastructure.

About
QDay brings together expertise across cryptography, blockchain engineering, distributed systems, and digital asset infrastructure to build practical post-quantum and agent-ready technology.
Our team focuses on the practical challenges of building secure, scalable and usable blockchain infrastructure: EVM compatibility, high-performance execution, payment flows, account abstraction, agent identity, APIs, and a progressive path toward post-quantum signing.
We are building QDay for developers, agents, applications, and organizations that need reliable infrastructure for the next phase of the onchain economy — from decentralized applications and real-world payments to machine-to-machine transactions and agentic commerce.
