Winternitz Development Update : October 23, 2026 Building towards a more secure, private, and post quantum ready wallet infrastructure. Today, we're sharing a summary of the development milestones completed on October 22, as we continue strengthening the Winternitz ecosystem ahead of broader testing and security review. Key Development Highlights 01. Wallet Dashboard Improvements Refined network switching, integrated official blockchain logos, and improved responsive layouts for a more consistent experience across devices. 02. Unified Privacy Workspace Consolidated privacy-related functionality into a single, more intuitive dashboard experience. 03. Independent Vault Management Introduced independent vault creation with separate cryptographic keys, passwords, and backups, alongside dedicated Send and Receive functionality for each account. 04. WOTS-Authorised Vault Profiles Implemented locally validated vault profiles supporting WOTS-based authorisation, revision hashes, and permanent profile freezing. 05. Verification & Recovery Expanded contract inspection, signing-key state verification, privacy-preserving diagnostic reports, and backup freshness checks. 06. Post-Quantum Infrastructure Advanced experimental XMSS message signing and local integration of an ERC-7579 WOTS validator module, progressing towards more flexible post-quantum account security. 07. Gas Sponsorship Infrastructure Implemented and successfully tested local ETH gas sponsorship infrastructure to support future improvements in transaction accessibility. 08. Independent Security Audit Preparation Expanded and refined the proposed technical review scope for Hacken, covering key components of the Winternitz security architecture. Testing & Validation Our latest development cycle successfully passed automated tests and production build checks, including 24 vault-specific browser checks. These results represent local development validation, not independent security certification. What's Next? Our upcoming priorities include public deployment of vault profiles, funded mainnet acceptance testing, ERC-8004 identity integration, token metadata support, USDG-based transaction fees, and an independent security audit.

Winternitz Vault from independent keys to onchain execution. Each vault uses its own WOTS keys, encrypted local storage, and a dedicated signing journal. Transactions are reviewed, signed, and saved before submission. Onchain validation advances the account’s key state, while confirmation checks the actual transaction outcome.

Quantum Computer Matters. Recent security incidents across the crypto industry have reminded us of one thing: digital asset security cannot be taken for granted. Today's exploits are not necessarily quantum-related. But they expose a broader reality: security threats continue to evolve, and our infrastructure must evolve with them. Quantum computing introduces another long-term challenge to the cryptographic foundations of blockchain technology. At Winternitz, we're exploring hash-based signatures, post-quantum authentication, and secure key rotation to help build a practical path towards quantum readiness. We're not waiting for quantum threats to become a reality before exploring solutions. Security is not just about protecting what we have today. It's about preparing for what comes next. The future of wallet security starts with the work we do today. winternitz.app

Official Statement from Winternitz Regarding the $WTZ Security Flag To our community, supporters, and $WTZ holders, First and foremost, we would like to sincerely apologise to everyone who was affected by the recent events surrounding $WTZ. During a period when our project was gaining momentum, $WTZ was unexpectedly flagged by Blockaid. This raised concerns across the community and coincided with a significant decline in the token's market price. We understand the frustration, uncertainty, and financial impact this situation may have caused, particularly for those who have supported Winternitz from the beginning. There is a possibility that the flag was triggered by external reports submitted to Blockaid. However, we cannot independently confirm what initiated the flag, and we do not wish to make accusations or assign blame. Today, we received official confirmation from the Blockaid Security Team. Following their investigation, Blockaid confirmed that the flagging of $WTZ was incorrect and that its status has been updated accordingly. We appreciate Blockaid's professionalism, their willingness to review our appeal, and their commitment to maintaining security standards across the ecosystem. To our holders and investors: we are truly sorry for the disruption and uncertainty this situation has caused. As a team, we take our responsibility to this community seriously. While market movements are beyond our direct control, transparency, communication, and continued development remain our priorities. This incident will not change our long-term commitment to Winternitz. We will continue building our post-quantum wallet infrastructure, progressing with testnet development, preparing for independent security audits, and working towards a more secure and reliable ecosystem. We are not here to point fingers. We are here to build meaningful technology and earn trust through consistent progress. The official clarification is now received. Our focus returns entirely to development. Thank you to everyone who stood by Winternitz during this challenging period. We keep building. We keep improving. We move forward together. — The Winternitz Team

Privacy is the next step for Winternitz. Your ETH. Your privacy. Your control. We're preparing to introduce Private Transactions to the Winternitz ecosystem, bringing a new layer of financial privacy to your wallet experience. Powered by an integration with RAILGUN, this upcoming feature is designed to let users: • Shield ETH into a private balance. • Transfer privately through supported privacy accounts. • Unshield funds back to Ethereum when needed. • Maintain greater control over their on-chain financial activity. We believe the future of Web3 should offer more than secure transactions. It should also give users meaningful control over their financial privacy. Post-quantum security and financial privacy are two important directions we're building towards. The integration is still undergoing validation and security testing before public release. Coming soon to Winternitz Wallet. Explore: winternitz.app

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.
