Chau - Soroban powered secure wills

SCF #33
$90.0K
Build
Not Awarded

A Stellar-powered platform for secure will creation and token issuance, featuring an AI agent to assist in generating wills. The platform prioritizes user privacy, simplicity, and legal compliance with seamless notary integration.

Products & Services

Chau offers legally compliant digital wills by combining an online questionnaire with notary integrations allowing Spanish residents (no matter the age) to access a better way to plan their estate. Our service is cheaper than notaries and lawyers, more accessible, guided and allows will-makers to plan their future at their pace.

We aim to expand our service with:

  1. Secure Data Encryption & Privacy

Encrypting all personal information (e.g., name, address) locally via an open-source tool that ensures Chau never sees unencrypted data. The encrypted data’s hash is stored in the user’s Stellar account metadata, giving them full control and ownership of their information.

  1. On-Chain Will Verification & Token Issuance

Once a user finalizes their will, Chau creates aunique Stellar issuer accountt hat stores the will_hash in its metadata and issues a custom WILL-TOKEN to the user’s Stellar wallet. This token:

Proves Ownership: Demonstrates that the user holds a validated record of their will.

Guarantees Immutability: The hashed will content is securely recorded on the Stellar ledger, preventing unauthorized changes.

  1. Ownership & Retrieval

By holding the WILL-TOKEN, users can verify their will’s authenticity at any time. They alone can decrypt personal details using the passphrase in Cryptometer, ensuring end-to-end privacy. This workflow preserves immutability on-chain while keeping sensitive data fully protected off-chain.

  1. AI-Enhanced Will Creation

Chau automates the drafting of wills using AI, reducing human error and legal costs. Users answer a brief questionnaire, and the platform generates a personalized will which is then checked by a lawyer to both improve the testament AI algorithm and ensure legal validity.

  1. Local Notary Integration

To comply with legal requirements, Chau provides an in-app directory of 400+ notaries. Users are guided to a suitable notary for official notarization, bridging the gap between digital proof and legal validity under current regulations. We aim to further integrate this within our core product.

We are build a service accessible for everyone giving the unique value of web3, while hiding its complexity and offering an experience more familiar with web2 applications.

Success Criteria

Monthly Will Creations:

  • Phase 1 (Feb 2025): 100 monthly wills, validating core functionality and user interest.

  • Phase 2 (May 2025): 500 monthly wills (100 on Soroban testnet), demonstrating scaling potential on Testnet.

  • Phase 3 (June 2025): 1,000 monthly wills (200 on Soroban mainnet), confirming readiness for Mainnet launch and broader market adoption.

AI-Driven Efficiency & Cost Reduction:

  • Reduced Legal & User Friction: AI-assisted drafting to cut lawyer review time by ~30% vs. traditional methods.

  • High User Satisfaction: Maintain an NPS score of 60+ to ensure the simplified process resonates with users.

Impact & Accessibility:

  • Serve Underserved Communities: Achieve a meaningful portion of sign-ups from rural or low-income regions, enhancing financial inclusion.

  • Secure Data Ownership: 100% of wills backed by Stellar tokens and local encryption (via SecureApp), guaranteeing privacy and control.

Local Partnerships & Compliance:

  • 400+ Notaries: Maintain and expand notary partnerships, ensuring users can easily comply with legal notarization requirements.

  • Legal Collaboration: Ongoing liaison with lawyers and notaries, crucial for compliance in Spain and future LATAM expansion.

Financial Metrics & Sustainability:

  • Month 1 Profitability: Continue surpassing COGS and operational expenses, validating a solid business model from the start.

  • 5:1 ROAS: Preserve or improve this ratio to show cost-efficient user acquisition and solid Series A–level marketing performance.

Go-To-Market Plan

  1. Bottom-of-Funnel Search & Sustainable Acquisition Metrics
    We have already established a data-driven approach focusing on high-intent search campaigns (e.g., “create a will online,” “notaries near me”) to attract users ready to take action. Our current cost-per-acquisition (CAC) stands at around 6 €, with a 1:5 CAC/LTV ratio, ensuring cost-effectiveness and early profitability metrics from the outset.

  2. Notaries as a Key SEO and Partnership Channel
    We have mapped the most-searched notaries to power our notary-locator feature, giving us strong SEO positioning around “find a notary” keywords. This approach has also enabled us to forge direct partnerships with notary offices, creating an additional revenue stream through referrals and strengthening Chau’s reputation as a trusted legal services connector.

  3. Influencer Marketing to Bridge Awareness and Acquisition
    Collaborations with influencers—particularly those in personal finance, family-focused, or legal education niches—will expand top-of-funnel awareness. By directing engaged audiences to Chau, we can reinforce our bottom-of-funnel efficiency and maintain steady, cost-effective conversions.

  4. Upselling from “Testamento de Bienes” to “Testamento Vital”
    We initially capture users seeking straightforward property-based estate planning (“testamento de bienes”) and then offer an upgrade pathway to a comprehensive “testamento vital,” covering additional directives like medical and guardianship instructions. This not only increases lifetime value (LTV) per user but also deepens Chau’s relationship with clients over the long term.

  5. Spain First, Italy and LATAM Next
    We focus on Spain initially due to a more approachable regulatory environment and significant existing traction. After refining our model, we’ll replicate it in Latin America, leveraging shared language, cultural similarities, and parallel legal frameworks—enabling efficient expansion with minimal operational friction.

  • 100+ Active Planners: Individuals actively preparing their wills or estate plans online.

  • 5:1 ROAS: Showcases Series A-level marketing efficiency, significantly boosting customer acquisition and supporting rapid scaling.

  • Month 1 Profitability: From day one, our sales have surpassed combined COGS and operational expenses, validating the business model’s feasibility.

  • 400 Notaries Onboarded: Ensures a broad legal network for notarization and compliance, strengthening user confidence.

  • NPS of 60+: Users are highly satisfied and likely to recommend our service.
