CIP-113 is moving from specification to operations. And that’s where things get interesting. At BlockSign, we have now successfully executed a governed programmable-token lifecycle on Cardano Preview: → Registration + initial mint → Separate mint → Wallet-to-wallet transfer → Burn All confirmed on-chain. But making a transaction work is only half the challenge. Institutional operations need to answer different questions: - Who is allowed to initiate it? - Who must approve it? - What exactly was approved? - Can the transaction change after approval? - Who can execute it? - And can all of this be proven afterwards? That’s why BlockSign separates: Intent → Build → Validate → Approve → Execute → Confirm → Evidence ❗️Changing the transaction means changing the approval.❗️ This week, CIP-113 builders are meeting to discuss improvements to the emerging infrastructure. Our testing is already producing concrete operational learnings around governance, transaction flows and the requirements for using programmable tokens in real-world environments. The next step is bigger than minting tokens. It’s making programmable assets operationally ready for institutions. @planetmaaz @michaeldotada @Cardano

Custody vs. non-custody. BlockSign never has your keys. Governance is not custody. On the BlockSign platform, asset owners define and enforce who is allowed to do what: roles, approvals, limits and policies — while remaining in full control of their assets. For institutional and professional investors that require custody, optional custody is provided by our regulated custody partner @nbxcom. BlockSign cannot access, move or manage your funds. Never!

The Cardano community backed BlockSign. Here’s what @Catalyst_onX funding made possible in one example: 🧵1/3 From Utility Bill Calculator to a Fully Digital Property Management Platform - How Hausakte24 and BlockSign Are Taking the Next Step in Digitalization: With its latest relaunch, Hausakte24 has introduced much more than a new design. The company is making a clear statement about its future direction: evolving from a utility bill calculation tool into an intelligent platform for digital property management. The relaunch also provides a glimpse into the next stage of development, including a modern user interface, new AI-powered features, and the continuous expansion of the platform. The goal is simple: reduce administrative work for landlords and further automate day-to-day processes. A key part of this evolution is the integration of BlockSign. Together, the two companies are creating two fully digital workflows that significantly simplify property management while providing greater legal certainty and transparency. 1️⃣ Delivering Utility Bills Securely and with Verifiable Proof Preparing a utility bill is often only the beginning. The real administrative work usually starts afterward: - Export the document as a PDF - Write an email or print a letter - Organize delivery - Archive delivery records - Respond to tenant inquiries With the integration of BlockSign, this becomes one seamless digital process. Once a utility bill has been generated, it can be sent directly from Hausakte24 to the respective tenant using BlockSign. The complete workflow takes place entirely within Hausakte24: 1. Generate the utility bill as a PDF 2. Automatically retrieve the tenant’s 3. contact details from existing records 4. Send the document via Registered Electronic Delivery 5. Automatically send reminders when required 6. Archive all delivery evidence in a tamper-proof, audit-ready manner The key advantage is the proof of delivery. While a conventional email merely proves that a message was sent, BlockSign creates a structured and tamper-evident record showing: ✅ when the document was made available, ✅ when the recipient accessed it, ✅ when receipt was acknowledged, ✅ a complete audit trail including trusted timestamps and integrity verification powered by Swisscom Trust Services. This provides landlords with a comprehensive and verifiable record of the entire delivery process, permanently stored within the digital property file. 2️⃣ Automatically Generate and Electronically Sign Rental Agreements Another major step forward is the digitalization of rental agreement creation. BlockSign includes functionality that automatically generates rental agreements from predefined templates using the property, unit, and tenant information already stored in Hausakte24. The system automatically imports information such as: - Landlord and tenant details - Property address and description - Lease commencement date and contract term - Monthly rent and advance service charges - Security deposit - Number of tenants - Custom contractual clauses Based on this information, BlockSign automatically generates a complete rental agreement using the predefined contract template. Manual data entry is eliminated entirely. After a brief review, the agreement can be sent directly to all parties for electronic signature. Landlords and tenants can sign online, either sequentially or in parallel. Once the signing process is complete, the following are automatically archived: - the electronically signed rental agreement, - all signature evidence, - qualified timestamps, and - the complete audit trail. The result is a fully digital contract lifecycle, from existing master data and automatic document generation to legally compliant electronic signatures and audit-proof archiving. 2/3 ⬇️

Wallets are as essential as browsers. They are the operational gateway through which digital assets are accessed, managed, secured, and governed. At BlockSign, we approached wallet infrastructure from the perspective of a trust-layer provider. We began with a 100% non-custodial architecture and developed the platform around the requirements of professional DeFi users, organisations, and teams. This meant going far beyond the basic storage of private keys. Professional digital asset operations require role-based permissions, policy-driven approvals, transaction limits, clear responsibilities, audit trails, and verifiable execution. Only after completing the self-custody model did we address the next challenge: How can the same modern operational structure fully meet the requirements of MiCA while preserving security, usability, and operational flexibility? The answer is a carefully integrated ecosystem of specialised partners. Through our strategic partner @nbxcom authorised as a Crypto-Asset Service Provider under MiCA, BlockSign can provide a regulated custody and crypto-asset services model across the European Economic Area. NBX is also approved as a recognised custodian of crypto-assets for exchange-listed products on SIX Swiss Exchange, demonstrating that its custody infrastructure meets the standards required for institutional capital-market products. Through NBX, Notabene provides the Travel Rule infrastructure, while Chainalysis supports transaction monitoring, wallet screening, and AML risk management. Together, BlockSign and its partner provide the custody, compliance, governance, security, and operational controls required for MiCA-compliant digital asset operations. Organisations can therefore choose between three models: 100% self-custody, regulated MiCA-compliant custody via NBX, or self-custody with an additional disaster-recovery layer. All three models are integrated into one policy-driven platform designed for professional digital asset operations. Because institutional wallet infrastructure is not only about holding assets. It is about control, accountability, compliance, security, and verifiable execution.

The hottest topic: Stablecoin Open USD 1. What is Open USD? Open USD, ticker OUSD, is a new U.S.-dollar stablecoin initiative by Open Standard. It was announced on June 30, 2026 and is expected to go live later in 2026. Open Standard describes it as a stablecoin for global money movement, built around three ideas: no mint/redeem fees for businesses, shared reserve economics, and collaborative governance through an independent company backed by partners. The important point: Open USD is not just another stablecoin. It is a distribution coalition. The official partner list includes payment networks, banks, fintechs, exchanges, wallets, infrastructure providers and blockchain ecosystems, including Visa, Stripe, Mastercard, American Express, BlackRock, BNY, Standard Chartered, Google, Shopify, Coinbase, Fireblocks, MetaMask, Solana, Base, Stellar, Polygon, Aptos Labs, Plasma and Tempo. 2. Is it good for users? Potentially yes, but not automatically: For users, the positive development is more competition. If Open USD really creates cheaper, more open stablecoin infrastructure, users could benefit from better availability, faster payments, more wallet/exchange support and potentially lower costs. Reuters reports that Open USD is designed to let businesses mint and redeem without cost or volume limits, while reserve earnings are shared with partners after a management fee. But the user benefit depends on whether companies actually pass those advantages through. A stablecoin can be cheaper at the infrastructure level while the end user still pays fees through wallets, exchanges, payment apps or merchants. 3. Biggest pros The biggest pro is distribution. Open USD has a very strong partner network from day one. Stablecoins win not only through technology, but through where they are accepted, who integrates them, and whether merchants, banks, wallets and payment processors actually use them. The second pro is competition with USDT and USDC. Fortune describes Open USD as a serious challenge to Tether and Circle, and reports that Tether and Circle are not part of the consortium. That matters because the stablecoin market has been highly concentrated around those two issuers. The third pro is governance and shared economics. Open Standard positions Open USD as a stablecoin where governance and economics are shared with the businesses growing adoption, rather than controlled by one dominant issuer. That could be attractive to large institutions that do not want to depend entirely on Circle or Tether. 4. Biggest contras The biggest risk is that the launch details are still incomplete. Open USD is announced, but not live. Fortune reported that Open Standard had not disclosed which blockchain the stablecoin will operate on. The official partner list includes several chain ecosystems, but a partner listing is not the same as a confirmed technical deployment. The third risk is centralization by another name. Open USD may be more open than a single-issuer model, but it is still a consortium of very large financial and technology companies. That can be good for adoption, but it does not automatically mean neutral public infrastructure. This is a real positive fact: Cardano’s native-asset model is technically elegant for stablecoins. Cardano’s developer documentation explains that native tokens are tracked directly by the ledger, without a smart contract for basic transfers, reducing contract-execution risk for simple token movement. 5. How could BlockSign add Open USD? Open USD creates more stablecoin competition. More competition creates more need for trust infrastructure. That is BlockSign’s field. Our conclusion: Open USD is a positive market signal because it increases stablecoin competition and moves the discussion from “who issued the biggest coin?” to “who controls distribution, trust, governance and real-world usage?”
