Appreciate the response, @hackenclub! 🛡️ We're still in the early stages of development and are working to ensure everything is properly prepared for an independent security audit. We'll reach out once we're ready to discuss the scope and next steps. Looking forward to the conversation. Security and transparency remain at the heart of what we're building at Winternitz.

Winternitz Update: Pre Mainnet Security Audit 🛡️ First, we want to apologize to the Hacken team for sharing a screenshot of our private conversation. We appreciate their outreach and support, and we respect the privacy of our discussions. However, we also want our community to understand the progress we're making and the work happening behind the scenes every day. Before launching Winternitz on mainnet, we’re taking an important step toward strengthening security. We’re pleased to share that Hacken will be auditing our smart contracts before the mainnet launch. Our goal is to have our contracts independently reviewed by an established security team, identify potential vulnerabilities, and address any issues before deployment. We understand how important security and trust are, especially for a post quantum wallet project. We want to learn from past challenges and take the necessary precautions to avoid repeating previous issues. We’re building Winternitz with a long term vision, and that means prioritizing security over rushing to launch. This is part of our commitment to building a more secure, reliable, and trustworthy product for everyone. No shortcuts. No rushing. Security first. More updates will follow as development and the pre mainnet audit process progress. Thank you for being part of the Winternitz journey.

Winternitz ($WTZ) Security Status Update We're pleased to share that $WTZ is now displaying “No issues” in the wallet's Security and Trust section, with the previous risk warning no longer appearing.

Hello everyone, Yesterday, we were deeply focused on building and improving the Winternitz ecosystem, and we hadn't yet had the opportunity to address the recent warning appearing on MetaMask. We've since reached out to the MetaMask Support Team, who confirmed that the WTZ token is currently being flagged by Blockaid's security system. We're now taking the next steps to contact @blockaid_ directly, understand what triggered the warning, and work towards resolving any identified issues. We take security concerns seriously and believe in addressing them through transparency and proper verification. In the meantime, development continues as planned. Our focus remains on improving Winternitz Wallet, strengthening our smart contracts, and preparing for independent security audits. We're still in the early stages, and there's plenty more to build. Thank you to everyone who continues to support Winternitz. We keep building. Security first. Transparency always.

We're still early, and there's more work ahead. 🔗 winternitz.app/

Winternitz Development Update We’ve added XMSS message signature verification to the web wallet and browser extension. Users can now check a signature against its message, smart account, and network. Verification combines local cryptographic checks with ERC-1271 validation at the same block without sending a transaction or consuming a signing leaf. We also added separate testnet deployment tooling with runtime bytecode and contract configuration checks. 1. 200 tests passed 2. Type checks and production build passed 3. Local deployment and revocation flows validated 4. One optional FFI test skipped Next: XMSS account creation, message key management, and dApp signing approval screens.

The wallet uses WOTS for asset transfers and message root management, while XMSS^MT handles message signing, providing a foundation for dApp login and proof of account control. As shown in the chart, the journal reserves an unused leaf before signing and records completion before releasing the signature. ERC-1271 checks the signature against the active message root. Each message is bound to the account, chain ID, and key epoch. Revoking the root causes previously issued signatures to fail subsequent verification. In two local tests, estimated ERC-1271 verification costs were approximately 2.43–2.64 million gas, including calldata. Verification costs still require optimization. The SDK and contracts have passed local validation. Next steps are web and extension integration, signing approval screens, and public testnet deployment of the new account version.

Good morning, good afternoon, and good evening to the Winternitz community, wherever you are in the world. 🌍 Another day of building at Winternitz.

Winternitz Preparing Wallet Security for the Post Quantum Future.

How Does a Winternitz Transaction Reach the Blockchain? The wallet constructs a UserOperation and signs it locally using Winternitz One Time Signatures (WOTS). A bundler then simulates the operation before submitting it to the EntryPoint contract. The EntryPoint coordinates verification through the smart account before executing the approved instructions. The bundler facilitates transaction submission and initially covers the gas fees, which are subsequently reimbursed using funds from the wallet. Throughout this process, the user's private keys remain securely on their device. This mechanism follows the ERC-4337 architecture.

8 hours spent today building the mobile version of Winternitz Wallet. From smart contracts to a mobile experience, we're gradually bringing post quantum wallet technology closer to everyday users. One step closer to bringing Winternitz to your pocket. Coming soon to iOS & Android. 🔐

Ethereum continues to push the boundaries of blockchain innovation, from account abstraction to longterm security research. As the ecosystem evolves, we believe post quantum cryptography represents another important area worth exploring. At Winternitz, we're contributing to that direction by developing hash based authorisation, onetime signatures, and automatic key rotation through ERC 4337. Our goal is simple: to explore and build additional security infrastructure that can support the longterm evolution of Ethereum and emerging EVM ecosystems, including Robinhood Chain. We've just published a technical article covering our architecture, security considerations, current limitations, and future development roadmap. Inspired by the ongoing innovation across the ecosystem, we'd be grateful to hear the perspectives of @VitalikButerin and @vladtenev on the future of post quantum security and blockchain infrastructure. Building towards a more resilient future for Ethereum and the broader EVM ecosystem. Read our full article below ↓

Winternitz Today's Development Agenda Today, we're focusing on two key priorities: 1. PQC Documentation Refining our public documentation to ensure the post-quantum security narrative accurately reflects our WOTS based implementation, including its capabilities and limitations. 02. Testnet Verification Reviewing existing deployments and available testnet evidence, with further verification focused on: Transaction execution and validation Onetime signing key rotation Wallet recovery and key state safety Our priority is to make Winternitz not only functional, but also transparent, verifiable, and technically sound. Still early. Still building.

A new era of digital asset security is on the horizon. Coming soon to the App Store and Google Play.
