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 ⬇️
