  1. Project Name & Description
    WƐ R Crypto. WƐCard

WƐCard is a prepaid credit card that is loaded with USDT and USDC on the Polygon network and now plans to integrate compatibility with the Rootstock (RSK) blockchain. The goal is for users to be able to load and use stablecoins on Rootstock seamlessly: from loading their card with cryptocurrencies to paying at physical and digital merchants, taking advantage of DeFi functionalities.

The card starts in Paraguay, and has been operational since August 12, 2025, and already has 119+ cards issued and active in South America, the United States, and Europe. With very competitive costs —only 1% on deposits and Visa exchange rates, reaching a zero exchange cost per transaction when used in dollar transactions— WƐCard is positioned as the most economical and efficient solution for crypto payments and remittances in countries where these services are not yet developed (such as Paraguay, Bolivia, and Peru). The card currently has users in the United States, Paraguay, Argentina, Brazil, and Italy.

From Paraguay, a country historically overrated in technological and financial innovation, WƐCard demonstrates that it is possible to create global payment infrastructure from emerging markets, connecting unbanked communities to the digital world.

  2. Technical Specs. WƐCard is a crypto-native prepaid card platform that enables users to fund VISA cards directly with cryptocurrencies. The system bridges blockchain-based assets and traditional payment rails, allowing real-world spending of stablecoins through a seamless and regulated interface.

    Core Technical Components

    1. Wallet Layer

      • Each user is assigned a self-generated wallet

      • The system supports multi-chain architecture (Polygon, and now Rootstock).

    2. Blockchain Integration Layer

      • Smart contract modules handle deposits, balances, and top-ups.

      • Integration with Rootstock will enable future transactions in RBTC and USDT

      • The platform uses Web3 interfaces to detect balances, confirm transactions, and trigger card top-ups automatically upon on-chain confirmation.

      • Cross-chain functionality allows users to transfer funds between Polygon and Rootstock, leveraging existing bridges or custom swap logic.

    3. Prepaid Card Credit Engine

      • When a user funds their wallet with supported crypto assets, the system converts and credits the equivalent fiat balance to the VISA prepaid card.

      • Card balances are updated in real-time.

      • Transaction fees, conversion rates, and limits are managed via configurable smart contract parameters.

    4. Frontend & UX Layer

      • Built in HTML/CSS/JS, with a dark interface.

      • Responsive design for web and mobile, ensuring seamless onboarding.

      • The wallet dashboard displays crypto balances, transaction history, limits and card status in real time.

    Technical Objectives for Rootstock Integration

    • Deploy and validate the full crypto-to-card flow on Rootstock testnet.

    • Enable USDT on Rootstock as the main top-up asset.

    Expected Technical Impact

    • Onboarding new Rootstock users via a practical, consumer-ready use case (crypto payments via card).

    • Demonstrating Rootstock’s compatibility with mainstream stablecoin operations.

    • Strengthening Rootstock’s position as a green and Bitcoin-secured blockchain for real financial products.

    1. Value Prop for Rootstock. • Facilitates Rootstock’s transition into a real-world blockchain through an active prepaid card.

      • Allows users to load USDT from Rootstock, integrating ecosystems.

      • Incorporates Dollar on Chain (DoC) and rBTC in the future, expanding the options for using the blockchain for everyday consumption.

      • Offers DoC staking, incentivizing active use of Rootstock.

      • Opens emerging markets in Brazil, Paraguay, Bolivia, and Peru, with high demand for efficient, low-cost payments and remittances.

      • Strategic positioning in green mining: Paraguay offers low-cost renewable electricity, allowing the card to be linked to financial products based on clean hashpower, strengthening Rootstock’s green narrative.

      • Integrate WƐCard into the Rootstock ecosystem, using the network as infrastructure for future issuance of proprietary stablecoins (USDT) backed by RBTC, crypto ramps for emerging markets, and digital payment and remittance services with significantly lower costs than traditional banks and fintech.

  3. Demo and Github repo. WƐCard’s software is proprietary and currently hosted in a private GitLab repository.
    Given the nature of the platform — which integrates financial infrastructure and card issuance systems — the source code is not publicly available for security and compliance reasons.

    However, we are pleased to offer the Rootstock Grants Team a live demonstration of the full product functionality, including wallet creation, crypto funding, and prepaid card usage.
    Upon request, we can also provide restricted, view-only GitLab repository for technical review under a confidentiality framework.

    We believe this approach maintains both transparency and security, while allowing Rootstock’s evaluators to fully validate the technology and implementation quality.

Hi WƐCard team!

First of all, thank you for sharing such a complete and well-structured proposal. It’s clear there’s a lot of work, vision, and ambition behind this project, and the idea of connecting Rootstock with real-world use cases like payments, remittances, and everyday spending is what many in the community have been hoping to see.

That said, I do think the total amount requested ($155K) feels quite high for an initial integration. Since several parts of the project still depend on technical validation and regulatory aspects (licensing, card issuer partnerships, etc.), it might be wiser to start with a smaller, technically focused first phase.

With that foundation, we could all better evaluate the technology and traction before moving on to larger milestones (such as events, card issuance, or the DoC/rBTC integrations).

Crypto-loaded credit cards are a hot topic right now, especially in Latam, with established players and strong entrants alike, such as Kast, Metamask Card, Redot Pay, Etherfi, Neobankless, etc.
A credit card tied to Rootstock could add to its Bitcoin-centric appeal, avoiding banks, fiat, etc.

The requested values seem way too high. We have entire projects here executed with a $10-30k budget split across milestones.

Some values seem off, like $25k for 2 events, $30k for issuing 100 cards, $15k for including DoC even after USDT is already working, and $20k for staking.

I’m not sure if it’s clear, these fundings are not meant for projects or participants to profit from. We’re a DAO with very limited budget and funding is meant to offer that little push or support for bootstrapped projects to build ideas and projects that would otherwise be just shy or being feasible. That little push they need to build something that will allow them to become self-sustainable.

If you can design a project that can integrate Rootstock native stablecoins with a well justified ~$10-30k budget, I’ll deffinitely support this.

Hi,

First of all, thank you very much for your valuable feedback. We truly appreciate your observations and have taken note of them carefully to ensure we build the strongest possible version of this project.

We completely agree that it makes sense to focus initially on Milestones 1 and 2 as the first phase of the grant, concentrating on the technical integration and foundational components. The subsequent stages—such as events for promotion and broader ecosystem engagement—can be developed as follow-up grants once we have validated traction and technology performance.

Taking this opportunity, we would also like to introduce our core team:

Alejandro González – 10 years of experience in Blockchain, Director of the Postgraduate Program in Blockchain and Law at Universidad Austral (Argentina), the leading private university in South America. Advisor to several Web3 projects, including Win Investments.

Fernando Casalino – Early Bitcoin adopter (since 2010), electronic technician, and experienced miner.

Joaquín Morínigo – One of Paraguay’s leading Web3 communicators with several years of experience in blockchain education and media.

Santiago Troche – Lawyer and university professor specializing in technology law and innovation.

We are currently aligning the legal and operational strategy for the deployment of the application and see this grant as a great opportunity to strengthen our connection with the Rootstock ecosystem. Our goal is not only to build on Rootstock but also to contribute to its growth by facilitating the launch and expansion of other projects through our infrastructure.

Regarding card issuer partnerships, the WƐCard system is already operational, currently serving 145 active clients. We have effective agreements with Visa network issuers, and we are in the process of expanding to Mastercard as well. One of our key objectives with this grant is to reinforce the collaboration with Rootstock, enabling other Rootstock-based projects to leverage WƐCard for payment and settlement solutions.

Thank you again for your consideration. We look forward to collaborating more closely and contributing to Rootstock’s mission of expanding real-world blockchain utility.

Regards,
Alejandro Gonzalez
On behalf of the WƐCard Team

Nowadays, the crypto credit card market is highly competitive. To compete effectively, a project needs a strong and distinctive value proposition, which I don’t clearly see in Wecard. I’ve personally tried numerous crypto cards but only continue using a few.

For example, EtherFi offers 3% cashback on every transaction, seamless on/off-ramping, and the ability to stake and utilize assets without selling them. Offramp Card, on the other hand, provides QR payment options in several LATAM countries and allows investment in tokenized stocks through its app.

My core question is: What unique offerings does Wecard provide that would incentivize users to stay and use it consistently? Furthermore, what specific market or user segment does Wecard aim to target?

Like @Kaf_StableLab I also have concerns regarding the requested grant amount. Without a clear unique value proposition and demonstrated success in an initial phase, it’s difficult to see the direct benefit to Rootstock. You mentioned having 119+ users in South America, the USA, and Europe, I’m curious how these users signed up, as I couldn’t find any public information about Wecard online beyond a LinkedIn profile.

I believe it would benefit Rootstock if this project could integrate Rootstock’s native stablecoin (USDRIF), not just USDC and USDT. Therefore, I strongly suggest that Wecard present more tangible use cases, articulate a stronger unique value proposition, clearly define its market positioning, and justify the grant request amount within the proposed framework after addressing these points.

Hi, thanks a lot for the valuable feedback — we truly appreciate it and see it as a great opportunity to keep improving the project.

We’re familiar with some of the projects mentioned (like Kast and Redot Pay) and recognize their strong contributions to the ecosystem. Our focus with WƐCard is to complement that landscape by building a fully crypto-native, non-custodial, and fully compliant card solution, keeping users in full control of their assets.

With 149 active users across 8 countries (they are increasing every day), our next step is to integrate Rootstock, enabling users to load their cards with USDT (Milestone 2) and later add DoC, eventually allowing direct rBTC loading — a vision led by our co-founder Fernando Casalino, active in crypto since 2010.

From a compliance standpoint, WƐCard’s profile is distinctly different from other initiatives in the space.
Personally, I’m both a lawyer and a developer with over 26 years of experience, which gives me a clear view of the legal challenges many crypto projects face.
While we deeply respect the projects mentioned, several of them — by design — operate as trading or custodial platforms, often relying on spreads between buy/sell operations, crypto custody, or integration with traditional banking structures.

WƐCard, by contrast, avoids all banking or fiat dependencies. It is not a trading platform, not a custodian, and not a fiat gateway, but a pure crypto payment ramp — a solution designed solely to enable payments directly in crypto, minimizing regulatory exposure while keeping the user experience seamless and secure y less-kyc.

We understand that the proposed budget may seem ambitious, but our intention is not to request the full amount through this grant, rather to cover the initial milestones that demonstrate the project’s evolution and alignment with the Rootstock roadmap.

In that sense, and considering your feedback, the budget allocated to events can be rethought to focus on collaborative community initiatives together with other blockchain projects — not only to raise awareness of WƐCard, but also to foster co-creation and maximize visibility for other ecosystem initiatives.

Our long-term vision remains to build a self-sustaining, user-governed DAO card, and we’d love to make that journey together with the Rootstock ecosystem, aligned with its mission of expanding real-world Bitcoin utility.

Thanks a lot, @Curia — we really appreciate your thoughtful feedback and the opportunity to clarify these points.

We agree that projects like EtherFi and Offramp Card are excellent references in the space. However, they operate with models tied to fiat and traditional banking rails, which inevitably introduce custodial, compliance, and cost complexities.

WƐCard’s approach is intentionally different: it’s a fully crypto-native, fully non-custodial webapp, designed so users can pay directly with their crypto — mainly stablecoins — without intermediaries or banking structures. We aim to maximize non-custodial control, keeping users fully in charge of their assets due to they only are at least a credit. At this stage, we’re not aiming to be a trading, investment, or staking platform; our focus is purely on making crypto payments simple, fast, and frictionless.

Regarding payment methods, QR support is certainly on our radar, but we prioritized NFC payments since our app is web-based and doesn’t rely on device camera permissions. This ensures smoother usability across devices and regions.

As for tokenized assets or similar utilities, while innovative, they involve significant legal challenges, especially across Latin America. As a lawyer with over 26 years of experience, I’m very aware of those regulatory risks. That’s why WƐCard focuses on a legally clean and compliant use case: enabling users to spend stablecoins directly, without custody or conversion layers.

We currently have 149 active users across 8 countries, and our landing page is available at www.mywecard.com.

In terms of roadmap, our immediate goal is to integrate the Rootstock blockchain, add USDT support (as the world’s most widely used stablecoin), and then incorporate DoC — with continued growth from there.

In a more advanced stage, we could explore staking or yield services based on Rootstock-native stablecoins and even rBTC, but that would come later, once the payment layer is fully consolidated and aligned with community priorities.

Our goal isn’t to compete with fiat-based card providers, but to complement the ecosystem by offering a truly crypto-native, fully non-custodial, compliant, and accessible payment ramp — one that keeps users in full control of their assets while expanding real-world Bitcoin utility through Rootstock.

Thank you for taking the time to craft this proposal. A credit card that integrates with the Rootstock blockchain is a compelling product. That said, it’s important that the card supports USDRif, Rootstock’s native stablecoin, enhancing both the user experience and ecosystem alignment.

As a final note, we would expect a significantly smaller budget ($10-20k per milestone) for this proposal to be approved.

Thanks for the detailed proposal and for being so engaged @WeCard . Excited by the idea of a project like WƐCard on Rootstock. We find ourselves aligned with the feedback from other delegates and seeing USDRif integration as a primary milestone, prioritized over others, would make this a much stronger proposal. On that same note of sustainable growth the requested budget feels a bit high for this stage. We’re looking forward to seeing how the proposal evolves.

12

First of all, thank you for the quick response and for explaining Wecard’s intention. I did try to access the Wecard website, but it wouldn’t load for me.

I have to be honest, it feels like what you’ve described are features that are becoming quite standard for crypto card projects. Saying it’s “fully crypto-native and non-custodial” which, in today’s landscape, one might expect as basic features rather than distinctive. The examples I mentioned earlier were meant to highlight that those projects each have distinctive value propositions, rather than implying specific features should be adopted. So, I’m still trying to understand: what truly makes Wecard stand out?

Let’s say I’m a crypto-native user who already uses USDT or USDC daily, why should I choose Wecard over other existing options? That’s the key question I want to understand. What’s the wow factor?

Lastly, as I’ve mentioned before and as other delegates have also pointed out, it seems that integrating Rootstock’s native stablecoin USDRIF could create benefits for the Rootstock ecosystem, more so than only supporting USDC and USDT. Therefore, at this point, I’m still not convinced enough to support the project.

Thank you very much for your thoughtful feedback and for taking the time to review our proposal so carefully. We truly appreciate the opportunity to reassess and refine our submission based on your insights.

As background, WƐCard was born out of a very concrete problem. Our founding team is based in Paraguay, where despite holding Bitcoin and stablecoins, we faced major difficulties using them in everyday life. Fiat on- and off-ramps in Paraguay are practically nonexistent, mainly because most of the well-known crypto card projects operate through banking rails. This means that converting crypto into local currency (the Guaraní) or USD could only be done peer-to-peer, often with spreads ranging from 5% to 8% — making real crypto usability highly inefficient.

That’s why we designed WƐCard structurally as a direct pay ramp — where users fund their prepaid VISA card with their own crypto and use it directly afterward, without intermediaries, conversions, or fiat dependencies. This is also why we initially started with USDC and USDT, as they are the most widely used and accessible stablecoins across the region.

Regarding your core question, the main distinction of WƐCard lies precisely in how it works at the infrastructure level.
When a user sends crypto to their WƐCard wallet, that balance is immediately credited to their VISA card in USD — usable anywhere in the world. We never custody user funds, never hold the crypto, and do not operate with FX spreads or conversion margins. Our only fee is at the moment of deposit, and it’s among the lowest in the market.

We sincerely value your input, particularly regarding Rootstock’s native stablecoins, and will take it into account as we continue improving our proposal and aligning more closely with the Rootstock ecosystem and your feedback and othters that we have already received.

Hi team,

Could you give more details on M1 on how the budget will be spent in order to achieve the deliverables?

  • Hiring of developers?
  • Licences?
  • Product team?

etc.

Thank you

The way I’m viewing this at the moment:

  • M1 incorporated USDRif, but at $25k, it’s a high cost and only delivers a transaction in testnet and a Figma app mockup.
  • M2 is a $15k ambitious event, looking to engage with authorities and Bitcoin miners.
  • It gets interesting at M3 with mainnet and a real work transaction, but +$15k we’re already at $55k so far.

WeCard has a local presence, reach and initial focus in Paraguay, and their ability to remain viable and compete with serious global players – like EtherFi, Kast, Redot, Metamask Card, Binance Card, Dolphin Card, which have strong appeals like cashback, low fees, wallet integration, exchange integration – is challenging.
From experience in my social crypto groups, many people find 1% fee for a crypto card expensive.

I think Rootstock deffinitely needs to have a crypto integrated Visa/Mastercard card.
But what would it cost to engage with one of these consolidated global crypto-cards with thousands of users who could cross-polinate and become Rootstock users? Less or more than $55k?

$55k is a high value comparing to our history of projects, and DAO treasury.
I feel like this proposal would need to decrease values very aggressively to make sense for the DAO.
If decreasing the values is not possible, due to expensive development/audit/etc costs, the team might need to look at other funding mechanisms, perhaps a VC funding interested in the equity, or an acceleration program so that they can have some support and reduce costs for some of the work to be done.

Thank you very much for your thoughtful and detailed feedback. We truly appreciate the time and care dedicated to evaluating our proposal and helping us refine it further.

We would like to respectfully clarify a few key points that may help contextualize our approach and cost structure:

  1. WƐCard’s Core Model
    Unlike most crypto cards currently on the market, WƐCard does not operate an exchange, custodial service, or conversion layer. Our model is purely a payment ramp, not a trading or fiat on/off-ramp solution. This means we do not hold or convert users’ cryptocurrencies at any stage — offering an extremely high level of security and transparency. Even if WƐCard were to cease operations, users would still be able to use their prepaid cards until their credited funds are fully spent.

  2. Market Comparisons & Costs
    Among the cards you mentioned, public data shows that:

    • MetaMask Card: Annual fee of US $199 for premium tiers, plus transaction fees (e.g., 0.875% for swaps, in addition to network gas).

    • Binance Card: Transaction fees around 0.9%, although Binance’s main business focus is exchange and trading, not payments.

    • Dolphin Card: Top-up fee of 0.25% and a 1% spending fee per transaction (minimum US $1). We have no minimun.

    • Kast Card: Card issuance cost starts at US $100, with premium tiers costing US $1,000 to US $10,000 per year.

By contrast, WƐCard charges no issuance fees, and a user would need to spend around US $10,000 before reaching a total cost of US $100 in fees — which makes our model substantially more affordable and transparent. You pay if you use.

  1. Current Traction
    We currently have 156 active users across eight countries, all acquired organically without paid advertising. Feedback has been consistently positive, particularly regarding our low-cost structure, simplified KYC process, and ease of use compared to competitors operating with complex banking or custodial systems.

  2. Development Scope & Costs
    The technical scope of Milestone 1 -and 3- includes creating an individual wallet for each user, integrating the Rootstock network as a funding route with both USDT and USDrif tokens, implementing DEX-based swaps for settlement into the VISA credit system, developing the full UX/UI layer, and maintaining the backend infrastructure required for ongoing operation.
    This represents approximately 1.5 months of full-time development, including blockchain integration, testing, and QA. That said, we fully acknowledge your observation and are reviewing ways to optimize and adjust the proposed budget to better align with Rootstock expectations.

  3. Community Engagement (Milestone 2)
    The proposed event — or potentially two — aims not only to promote WƐCard but also to increase Rootstock’s visibility and adoption among users, miners, and fintech professionals. We are open to hosting and co-branding this space to showcase other Rootstock-based projects, ensuring it provides broader value to the ecosystem as a whole.

We deeply value this constructive dialogue and the insights provided by the Rootstock community. Your feedback is helping us strengthen both the project and its alignment with ecosystem priorities, and we remain fully committed to adjusting our proposal accordingly.

HI, Fernando here, Co-founder of WeCard.

We filmed some quick videos showing how the app works, and then buying something in a convenience store, here in Buenos Aires.

Excuse my bad diction and thank you!

Thank you for sharing additional materials, it’s clear there’s genuine effort and long-term vision behind this initiative. The idea of extending Rootstock into everyday financial use cases is highly relevant, and WƐCard’s progress in Paraguay shows that the team is building, not just theorizing.

At the same time, this proposal still spans too broad a scope for an initial integration. Seven milestones, marketing components, and even energy-related financial products make it difficult to assess where the technical work on Rootstock truly begins and ends. For a grant of this size, the community needs to see precise technical validation: a public testnet demo with on-chain transactions, documentation of how Rootstock assets are integrated, and clear information on compliance, including issuer/BIN partner and KYC/AML processes.

Given those pending elements, I’d recommend narrowing the focus to one clear technical milestone: delivering a verifiable Rootstock wallet flow and card top-up demonstration. Once that foundation is public and reproducible, expanding into additional milestones or co-branded initiatives would be much easier to support with confidence.

WƐCard is pursuing a valuable direction and the team’s openness to feedback is appreciated. Strengthening technical transparency and compliance alignment will make this a much stronger fit for Rootstock’s grants framework.
