Stablecoin
Describe your established collaborations.
Mynth (mynth.ai) – Provides the infrastructure to integrate Stable with Cardano, managing technical development and deployment.
Stable (stable.xyz) – Offers the platform for instant, feeless USDT issuance and transfers.
This collaboration will connect Stable’s USDT network to Cardano via Mynth’s systems, enabling seamless USDT access. Press releases will follow funding to drive adoption.
Describe funding commitments.
Mynth – Contributes in-kind resources, including engineering, project management, and infrastructure for the Cardano integration.
Stable – Provides technical support, API access, and compliance guidance at no cost during the project. No direct monetary funding is committed; all Catalyst funds will be allocated to development, deployment and marketing.
Describe your key performance metrics.
User Adoption – Number of unique Cardano wallets transacting in USDT; measures market penetration and real-world use.
Transaction Volume – Total USDT value moved on Cardano; reflects liquidity flow and integration success.
Transaction Speed & Cost – Average settlement time and fees; validates “instant, feeless” promise.
Please describe your proposed solution and how it addresses the problem
Our solution is to connect Cardano directly with Stable’s USDT network through infrastructure powered by Mynth. This will allow Cardano users to send and receive USDT with the same ease as any other asset in their Cardano wallets, dApps, and services, while benefiting from Stable’s fast, low-cost settlement system.
Mynth will develop the integration layer that links Cardano to Stable, enabling USDT to work seamlessly alongside Cardano’s native stablecoins, such as USDM and USDA, without extra steps or complex bridging. The experience will be fully integrated: users transact as they normally would, and the system handles interoperability in the background.
By combining Stable’s fast and feeless settlement infrastructure with Mynth’s leading blockchain interoperability, this brings Cardano into the world’s most widely used stablecoin economy while enhancing the utility of its own native stablecoins. The design prioritizes reliability, compliance readiness, and ease of adoption for developers, merchants, and end users.
This approach closes one of Cardano’s most significant gaps by enabling smooth, secure interoperability with global stablecoin liquidity, positioning the network as a more connected and competitive player in the global financial landscape.
Please define the positive impact your project will have on the wider Cardano community
By enabling seamless interoperability between USDT and Cardano’s native stablecoins, our project will unlock access to the world’s most widely used stablecoin economy for every Cardano user, developer, and merchant. This will make Cardano more attractive to global users, stimulate real-world payment adoption, and strengthen the ecosystem’s DeFi capabilities.
We will measure impact quantitatively by tracking:
We will also gather qualitative feedback from developers, merchants, and end users to assess usability and identify opportunities for further growth.
All outputs, including integration documentation, developer guides, usage statistics, and adoption reports, will be shared openly with the Cardano community through Mynth’s X and Discord channels. This ensures transparency, encourages ecosystem-wide adoption, and allows other builders to leverage the integration for their own projects.
Through this, the Cardano community gains a direct link to global stablecoin liquidity, enhancing network utility, growing its user base, and positioning Cardano as a competitive and connected blockchain in the global financial landscape.
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?
Our team has already proven our ability to deliver complex, high-impact projects with no external funding by successfully building Mynth from the ground up. Over the past two years, we have worked tirelessly to bring true interoperability to Cardano, designing and deploying foundational infrastructure that is already enabling cross-chain connectivity.
We are one of Cardano’s leading interoperability teams, with deep expertise in blockchain architecture, protocol integration, and wallet connectivity. Our prior work on Mynth has given us both the technical knowledge and the operational experience to deliver on this proposal efficiently and to the highest standards.
Our approach to project delivery is structured and accountable:
Given our history, expertise, and established technical foundation, we are uniquely positioned to deliver this SDK quickly, reliably, and with full transparency to the Cardano community.

Summary:
How does the cost of the project represent value for the Cardano ecosystem?
Connecting Cardano to the world’s most used stablecoin removes one of the ecosystem’s largest barriers to adoption. Billions in liquidity are currently locked out because USDT is unavailable, and this limits both developer and user participation. By delivering seamless USDT interoperability, we directly address that gap, creating a clear pathway for global users, merchants, and dApps to transact on Cardano without friction. The result is a measurable increase in wallets, transaction volume, and overall ecosystem activity that compounds far beyond the initial delivery period.
The proposed costs align with standard market rates for blockchain development and related services. Experienced developers in this field commonly command hourly rates in line with those used for the calculations, reflecting both the complexity of interoperability engineering and the need for reliability at production scale. Security allocations are justified given the high-value nature of stablecoin transactions. Penetration testing and bug bounties are industry-standard measures to ensure user safety and instill trust. Marketing efforts are equally critical: without a strong adoption push, even the best infrastructure risks underutilization. Strategic content, PR, and community engagement are proven methods in Web3 markets to accelerate adoption and build network effects.
By establishing seamless USDT interoperability, Cardano gains a critical piece of financial infrastructure that unlocks liquidity, strengthens DeFi capabilities, and expands global usability. The benefits extend well beyond a single integration: developers gain a reliable building block, users gain frictionless access to the world’s most used stablecoin, and the ecosystem as a whole gains credibility and competitiveness in the global crypto economy.
