Please describe your proposed solution

In conventional setups, within a specific jurisdiction, there are usually several public and private savings solutions available, which have incentives for individuals to use them. Beyond potential existing public pension schemes you receive a tax benefit in such private savings solutions, usually with the necessity to ring-fence such savings for a specific purpose, such as for instance house purchase or for retirement. When you pass away before retirement, it is your next of kin who receive the inheritance and it all goes through the usual legal machinery.

What all of these solutions have in common is that they are set up with a specific bank account and/or depot for the individual, where the bank/broker is conducting the investments in accordance with the savings plan specifics.

At Brick Towers, we provide an entirely alternative private savings and pension solution whereby the individual and his/her loved ones are deciding for themselves how they want to save their money and also for whom. At the center of this platform, “urble” (short for you are able) is a self-custodial wallet, allowing to receive, hold and send coins, pay from the wallet with a debit card and includes a digital contract-based framework that is used by an urble user to decide

• Purpose of savings
• Length of savings plan
• Beneficiary of savings
• Optionally: Definition of milestones and conditions with concrete paths for what shall be done if they are reached or not reached

The savings plans also allow for joint saving setups between couples, family members of just friends

Typical use cases of such savings plans which may have a long time horizon or also only a very short one:

1. Urble user wants to lose weight and sets up a savings plan where upon reaching the goal gets the savings and if not, donates part of it to a charity
2. A parent wants to save for their child until they reach a specific age or moment in their life and hands the savings over according to a pre-defined time and conditions (if conditions are not met also defines what shall happen). The parent also wants to motivate the child in certain situations which leads to a potentially higher savings amount.
3. A couple wants to save for their joint house purchase in the future and sets up contribution plans with individual amounts which upon separation beforehand are resolved in accordance with a specific share of the overall amount.
4. Golf buddies want to bet on the next tee who will have the longer drive, pay the same amount, and then the winner gets the full amount. If there is no consensus, the full amount is sent to charity.

Whenever a check or a control on a certain defined milestone or condition for the savings in the plan to be released is necessary, proof is to be provided by a validation mechanism. During the initial MVP Phase, this shall be provided by social proof, i.e. a nominated individual who confirms acceptance or rejection of a milestone/condition. At a later stage of the project, such validations shall be automated using trustless validation frameworks (oracle-fed validation).

The attached product deck as well as the draft website outline these concepts in more detail.

Please define the positive impact your project will have on the wider Cardano community

urble’s ambition is to become the de-facto standard for global self-sovereign private savings solutions. Cardano is unique in its approach to combining innovation with valuable components from other blockchain ecosystems, based on rigorous academic and technical validation and verifiability. urble aims to make people think about their priorities over long-term benefits from saving rather than short-term monetary gratification and thus spans over multiple decades. As such, the approach towards development and adoption will be very similar to Cardano’s. As such, Cardano will be validated as the go-to platform for high-value, sustainable, and critical next-generation savings infrastructure.

urble will have to use many other service providers in the Cardano ecosystem, leading to joint efforts and, hopefully, increasing adoption while driving greater demand for block space. In summary:

• Increased Adoption of Cardano Technology: urble’s use of Cardano's native tokens and wallet infrastructure ensures that users interact directly with the Cardano blockchain, which increases its usage and overall adoption. Additionally, urble's integration of ADA on/off-ramps and support for other blockchain assets (BTC, ETH) will further enhance the Cardano ecosystem's appeal as a cross-chain platform.
• Sustainable and Long-Term Solutions: urble emphasizes long-term, sustainable savings, which aligns with Cardano's vision of building a robust financial infrastructure. This long-term focus, which spans multiple decades, mirrors Cardano's approach, providing value by positioning it as the go-to platform for innovative financial products like savings and pensions.
• Joint Ecosystem Collaboration: The urble platform's need for services like fiat on-/off-ramps, stablecoins, KYC and AML processes, debit card usage and DeFi interactions creates opportunities for collaborations with other projects in the Cardano ecosystem. This cross-collaboration strengthens the ecosystem and leads to joint efforts that improve both adoption and technical capabilities.

What is your capability to deliver your project with high levels of trust and accountability? How do you intend to validate if your approach is feasible?

Brick Towers consists of 4 co-founders (2 business/product, 2 full-stack engineers) who have combined expertise in traditional finance and blockchain-based technology and products. Before co-founding Brick Towers, we delivered regulated accumulation, decumulation, one-off, and accumulation-decumulation savings products at Leonteq (first IPOed FinTech in Switzerland) for the Swiss and European insurance and banking market, together with some of the largest Swiss insurance companies and banks (Helvetia, Mobiliar, Raiffeisen, Glarner Kantonalbank). In the blockchain and Web3 industry, the Co-Founders have worked with and delivered key solutions for Pillar Project, Digital Asset and Noumena Digital. With Brick Towers, we build a global savings platform to access and make digital assets yielding. Our non-custodial staking service is SOC 2 Type II certified. We can now combine the knowledge and expertise to build a suitable and scalable global savings solution based on Cardano (and later Midnight for privacy concerns). This builds a valid cross-border alternative to existing public savings and pension solutions.

What are the key milestones you need to achieve in order to complete your project successfully?

How does the cost of the project represent value for money for the Cardano ecosystem?

The urble project represents significant value for the Cardano ecosystem by addressing a crucial gap: creating a global, self-sovereign savings platform that operates beyond traditional banking infrastructures, being a killer app for crypto. By leveraging Cardano's decentralized and secure blockchain, urble offers a unique value proposition—empowering users to create personalized savings solutions for themselves and their loved ones.

Western countries with advanced pension systems, such as Switzerland, are facing increasing management costs for pension solutions. Additionally, aging populations pose significant challenges to existing pension schemes. Urble, as a decentralized savings solution, provides a global, accessible alternative at a much lower cost, directly benefiting savers. With decades of experience in traditional finance, particularly in structuring innovative savings solutions, the Brick Towers team focuses on delivering solutions that enhance accessibility and cost-efficiency for the Cardano ecosystem and its users.

The proposed milestones follow a lean and transparent development process, which ensures a cost-effective implementation of the project. By focusing on core MVP functionalities, such as wallet creation, savings plans, and fiat integration, the proposal ensures that resources are efficiently utilized to deliver real, impactful results.
