[1411] - Milestone 3 Update – BΔLT: Bitcoin Autonomous Legacy Trust

Hi everyone,

We’re glad to share an update on **Milestone 3
**

Executive Summary

During Milestone 3 we focused on validating and scaling BΔLT’s growth strategy, combining a strong presence at events with user acquisition campaigns, partnerships with educational communities, and synergies with projects in the Rootstock ecosystem.

The main driver was LABITCONF 2025, held on November 7–8 at Costa Salguero, Buenos Aires, with over 9,000 attendees from across Latin America. BΔLT participated as an official sponsor, presenting its Bitcoin inheritance protocol built on Rootstock to end users, builders, and integrators.

Our presence included:

  • A dedicated booth with video demos, printed materials, and the full team answering questions.

  • The “Unlock the Legacy” interactive activation, a mini treasure hunt within the venue.

  • A talk by our founder, Jonathan Bravetti, focused on smart contracts on Bitcoin and the BΔLT use case, delivered to a full room (~40 attendees).

  • Media coverage and interviews with crypto outlets and institutional actors.

From this presence we obtained more than 600 leads in total, dozens of high-quality conversations with users and integrators, and opened doors for new partnerships and future BΔLT presentations in other countries across the region.

2. Progress Against Milestone 3 Objectives

2.1. Design and implement a user acquisition campaign

The objective of designing and implementing a user acquisition campaign was achieved through the “Unlock the Legacy” activation at LABITCONF:

· Attendees scanned a QR code at the BΔLT booth to start the experience.

· They had to find 4 clues scattered across different points of the event (physical spots and social media).

· With those clues they discovered a 4-digit code and validated it on a dedicated landing page.

· After completing the journey, they entered a daily raffle (including a hardware wallet as a main prize).

This gamified mechanic allowed us to:

· Educate about the Bitcoin inheritance problem in a light, engaging way.

· Capture contact data and segment users based on their level of knowledge and interest.

· Generate organic conversations around BΔLT throughout the event.

Key results from the campaign:

· 190+ participants completed the activation.

· 400+ qualified leads obtained directly from the activation flow.

· 600 total leads combining activation + direct booth interactions.

· Approximate investment: USD 5,000Estimated CPL ~ USD 8.

2.2. Establish partnerships with Bitcoin education communities and privacy-focused groups

During Milestone 3 we moved forward with new relationships with communities and organizations focused on Bitcoin education and adoption:

· Active contact with ONG Bitcoin Argentina and ONG Bitcoin Chile to explore collaborations on talks and educational content where BΔLT is presented as a real-world infrastructure use case on Bitcoin.

· Launch of Bitcoin Canning, a local community oriented toward Bitcoin education, where BΔLT is positioned as a concrete example of how to plan long-term digital legacy.

· Ongoing synergy with Money On Chain to integrate DoC and BPRO into BΔLT, expanding the set of supported assets (especially for more conservative, collateralized strategies), and coordinating future live sessions to educate about these integrations.

These partnerships help to:

· Position BΔLT as a real solution within existing educational journeys.

· Reach profiles that strongly value privacy, self-custody, and long-term security.

2.3. Participate in relevant Web3/Bitcoin events to present BΔLT and network

Beyond the acquisition campaign itself, LABITCONF served as the central hub for networking:

  • BΔLT participated as a sponsor, with brand visibility across the event and in official communications.

  • A technical talk on smart contracts on Bitcoin and the BΔLT use case reinforced the project’s credibility among developers and builders.

  • 8+ interviews with relevant media and institutional actors, including:

    • Crypto news outlets (e.g., iProUP, Criptonoticias).

    • Institutional actors such as the Government of the City of Buenos Aires.

From these interactions we obtained:

  • Invitations to participate in future blockchain conferences in Peru, Bolivia, and Colombia, expanding BΔLT’s regional reach.

  • Bridges with other infrastructure projects on Bitcoin interested in integrating or co-creating legacy, security, and self-custody solutions.

Additionally, we plan to attend DevConnect Argentina as participants to continue building relationships with developers and exploring future technical integrations.

2.4. Run targeted onboarding events or workshops

To complement our physical presence at LABITCONF, we ran a series of live sessions on X (Twitter Spaces) focused on:

· Explaining what BΔLT is and how the vault creation and claim flow works.

· Addressing frequent questions about inheritance, security, self-custody, and real use cases.

· Inviting listeners to try the protocol and follow project updates.

These spaces function as small online onboarding workshops and can be reused as evergreen content for new users discovering BΔLT after LABITCONF.

2.5. Gather qualitative feedback from users via public channels

During LABITCONF we received direct feedback from:

· Long-term Bitcoiners concerned with the legacy of their holdings.

· Newer users who saw BΔLT as a sort of “safety net” in case of unexpected events.

· Builders and integrators evaluating how BΔLT could plug into their own products.

Main insights:

· The Bitcoin inheritance problem is very real and tangible for the community, but very few people have a structured solution.

· BΔLT provides the most value when communicated as neutral, non-custodial infrastructure, rather than a closed, opinionated product.

· There is strong interest in expanding the protocol to new use cases beyond pure inheritance (e.g., long-term plans, family vaults, or contingency mechanisms for companies).

As a follow-up, with the 600 contacts captured:

· We are preparing a post-LABITCONF newsletter to maintain the relationship, share progress, and collect feedback in a more structured way.

· We will encourage participation in Discord/social channels to keep gathering qualitative feedback to guide protocol iterations.

2.6. Publish a transparent update on growth efforts, lessons learned, and community adoption strategies

This Milestone 3 closing report transparently summarizes:

· The actions executed.

· The quantitative results obtained.

· The key learnings and next steps.

In addition, we plan to publish a public update (post on X/LinkedIn + entry on our website and Rootstock channels) including:

· A recap of our participation at LABITCONF.

· Activation and lead metrics.

· Upcoming milestones in the BΔLT roadmap, including integration with Money On Chain tokens and expansion into new use cases.

2.7. Commission model update (based on LABITCONF feedback)

One of the strongest pieces of feedback we received at LABITCONF was related to fees and incentives. Builders and users were particularly sensitive to how commissions are applied in a long-term inheritance product.

Based on these conversations, we:

· Ran real-world tests on Rootstock mainnet with 0% commission to validate user flows and behavior.

· Used the insights from these tests to define a new commission model that permanently keeps a 0% fee tier for deposits ≤ 0.01 BTC, and applies a more granular and fair rate structure for larger deposits.

The updated Commission Model is as follows:

· When charged:
A single commission is charged at registration and automatically deducted from the deposit.
No fees are charged at claim.

· Free tier:
Deposits ≤ 0.01 BTC incur 0% commission.

· Dynamic rate by amount (bps):

o ≤ 5 BTC: 0.80% (80 bps)

o > 5 – ≤ 30 BTC: 0.70% (70 bps)

o > 30 – ≤ 100 BTC: 0.60% (60 bps)

o > 100 BTC: 0.50% (50 bps)

· Commission caps (by deposit size):
The applied commission is:
min(rate × deposit, cap), where the cap depends on the deposit size:

o ≤ 50 BTC → 0.20 BTC

o ≤ 250 BTC → 0.30 BTC

o ≤ 500 BTC → 0.40 BTC

o ≤ 1,000 BTC → 0.50 BTC

o > 1,000 BTC → 0.75 BTC

· Minimum effective deposit:
After deducting the commission, the remaining amount must be ≥ 1,000 satoshis.

· Cancellations:
If the testator cancels the vault, the remaining balance is returned to the testator;
the commission already charged is not refunded.

· Transparency:
All commission parameters are computed on-chain and emitted in the FeeApplied event:
bps used, cap applied, fee charged, and gross deposit.

· Notes:
Extending the inactivity period does not change the commission already paid.
Top-ups are not supported in this version.

This new model aligns incentives better across deposit sizes, keeps small users in a 0% fee tier, and provides clear on-chain transparency for all fee-related parameters.

3. Key Metrics for Milestone 3

· Event attendance: 9,000+ people at LABITCONF 2025.

· “Unlock the Legacy” activation participants: 190+.

· Qualified leads (activation): 400+.

· Total leads (activation + booth): 600.

· Media / institutional interviews and appearances: 8+.

· Estimated investment in LABITCONF: USD 5,000.

· Estimated Cost per Lead (CPL): ~USD 8.

· New event invitations: at least 3 countries (Peru, Bolivia, Colombia).

4. Learnings and Next Steps

Key learnings

· The Bitcoin inheritance problem is real and top-of-mind, and BΔLT fits well as neutral infrastructure on Rootstock.

· Gamified experiences like “Unlock the Legacy” are highly effective for education + acquisition in crowded event environments.

· A clear physical presence (booth, video demo, physical clues, printed materials) significantly increases traffic and meaningful conversations.

· Collaboration with ecosystem projects like Money On Chain strengthens BΔLT’s value proposition by expanding supported assets and adding new audiences.

Next steps derived from Milestone 3

· Launch the post-LABITCONF newsletter and establish a recurring communication flow with the 600 leads captured.

· Move forward with the technical integration of DoC and BPRO into BΔLT and define joint educational campaigns with Money On Chain.

· Design a 100% online version of the “Unlock the Legacy” activation to keep acquiring users outside of physical events.

· Formalize collaborations with ONG Bitcoin Argentina, ONG Bitcoin Chile, and Bitcoin Canning around educational content and workshops on inheritance and security.

· Continue expanding BΔLT to new use cases, while preserving the same non-custodial contract infrastructure on Rootstock as the foundation.

5. Conclusion

With the actions described above, we consider that Milestone 3 – Growth Strategy with Clear Objectives is successfully completed:

· We designed and implemented a concrete, measurable user acquisition campaign.

· We advanced partnerships with educational communities and ecosystem projects.

· We participated meaningfully in the most important Bitcoin event in LATAM and opened doors in new countries.

· We ran onboarding and awareness activities online.

· We collected qualitative feedback that is already influencing the product roadmap.

· We documented efforts, results, and learnings in this report for the community and for Rootstock Collective.

Thanks to the Rootstock Collective and the community for your continued support on this project.
Bitcoin is more than money is LEGACY.

Thanks for sharing this update. The work at LABITCONF and the acquisition results stand out, and the commission-model revision shows you’re listening closely to users and adjusting where needed.

As a next step, it would be great to complement this with some metrics tied to actual protocol usage (vaults created, deposits, claim flows tested), just to connect the growth efforts with on-chain activity.

Overall, appreciate the transparency and consistency, updates like this make it easier for the whole Collective to learn and keep improving.

[0212] - BΔLT – Rootstock Grant Impact Dashboard (Milestones 1–3)

Hi everyone,

As requested, we are sharing the BΔLT grant impact dashboard summarizing the results and contributions delivered to the Rootstock ecosystem for Milestones 1–3.

Dashboard (Google Sheet)

The file includes:

  • Overview / KPIs: high-level view of the project, key metrics, and grant summary.

  • Milestones & Deliverables: what was originally proposed vs. what was delivered for Milestones 1, 2 and 3.

  • On-chain overview: main Rootstock contracts (InheritanceFactory RBTC on mainnet and testnet) and notes on current metrics tracking.

  • Ecosystem impact: events, community activities, and partnerships where BΔLT has represented Rootstock (LABITCONF 2025, DescentralizAR, Blockchain Summit Global, Twitter Spaces, Bitcoin communities, etc.).

  • Grant allocation: breakdown of how the ~20,000 USD grant was used across audit, development, events, marketing, and community work, plus an estimate of additional self-funded costs by JXLabs.

Additional ecosystem value – Money On Chain integration

Beyond the original scope of the grant, we also integrated BΔLT with DoC and BPRO from Money On Chain, both running on Rootstock.
This expands BΔLT beyond RBTC-only vaults and:

  • Adds support for Bitcoin-backed stable assets (DoC) and BPRO,

  • Increases composability within the Rootstock DeFi ecosystem,

  • Creates new inheritance and backup strategies for users who already hold Money On Chain assets.

This integration work was self-funded by JXLabs (not charged to the grant) as part of our long-term bet on Rootstock.

Current adoption & next steps

Being transparent: BΔLT has not yet achieved strong community adoption or TVL on Rootstock.
The use case of inheritance is:

  • Less “visible” than trading or yield,

  • But absolutely critical for Bitcoin’s long-term story.

We see BΔLT as long-term infrastructure: something users may not need every day, but that becomes indispensable as their Bitcoin (and Rootstock-based assets) grow in value and time.

Going forward, we will:

  • Keep improving the UX based on real user feedback.
  • Add support for additional wallets to increase reach and make BΔLT more accessible to different user profiles.
  • Continue collaborating with Rootstock-native projects (like Money On Chain) and Bitcoin communities in LATAM.
  • Focus on education and awareness so that inheritance and contingency planning become a standard conversation for Bitcoiners, not an afterthought.

We are convinced that, over the next cycles, inheritance will become a key narrative for Bitcoin, and that BΔLT can strengthen Rootstock by offering a concrete, non-custodial solution in this space.

Any feedback, questions or suggestions from the community are very welcome.

Thanks again for your support.
