Agent-ReadyComing soon
Native x402 and AA smart wallet support are on the way, so agents and automated services can pay per request for API calls, compute and service exchanges.
Aevum Testnet is live · Chain ID 44005
The trust layer behind every agentic transaction
A post-quantum, scalable blockchain network built for payments, decentralized applications, and the agentic economy.
Agentic Payments & Commerce
Coming soon: let agents, applications, and services initiate programmable payments through APIs, smart wallets, and x402.
Scalable & Low-Cost
Build and transact with high throughput and low fees for frequent onchain activity, designed for sub-second settlement at mainnet.
Post-Quantum by Design
Built around a progressive path from classical signing to hybrid and eventually native post-quantum signing.

The Blockchain You Need for the Agentic World
QDay introduces a robust and scalable infrastructure designed to tackle the challenges of machine-to-machine payments today and quantum security tomorrow.
High-Performance Scalability
Engineered for high-frequency transactions, targeting sub-second settlement and sub-cent costs at mainnet.
Robust Developer Toolkits
Deploy today with the EVM tools you already use: Foundry, Hardhat, viem and ethers. QDay SDKs and APIs for payments and agents are coming soon.
EVM-Compatibility
Deploy new or existing EVM dApps effortlessly — same tools, same frameworks, zero migration friction.
InteroperabilityComing soon
Bridging assets and data across the broader EVM ecosystem is being deployed on Aevum, alongside QDay Bridge.
Post-Quantum Security
Built for the Post-Quantum Era
QDay is designed around a progressive path from classical ECDSA to hybrid ECDSA + ML-DSA-65 and eventually native post-quantum signing, helping applications prepare for a changing cryptographic threat landscape.
For developers
Start building in minutes
Aevum is EVM-compatible: keep Foundry, Hardhat, viem and ethers, point them at one RPC and deploy. Agent payments with x402 are coming next.
