QDay

An EVM-compatible testnet with a post-quantum roadmap

About QDay

QDay is an EVM-compatible blockchain network developing infrastructure for decentralized applications and programmable payments. Its public Aevum testnet lets developers deploy Solidity contracts using familiar tools such as Foundry, Hardhat, and Remix. Applications can connect through standard Ethereum JSON-RPC interfaces, while a faucet supplies test tokens and an explorer shows network activity.

Developers can use the testnet to experiment with contracts and integrations before the planned mainnet rollout. QDay also outlines a gradual transition from conventional signatures to hybrid and native post-quantum signing. Agent wallets, x402 payments, smart accounts, and dedicated payment SDKs remain on the roadmap, so the currently available network should be understood as a development and testing environment.
