FusionFi Core: Lending, Stablecoin & Multisig Infrastructure for Cardano
fusionfi
Description
FusionFi Core is a modular, open-source toolkit that enables the next wave of DeFi on Cardano. Developed by EMURGO Labs, in collaboration with Anzens and Encryptus. FusionFi Core includes:
Lending Contracts (Aiken)
Reusable modules for pooled lending, liquidation, interest accrual
USDA Integration Wrapper
Developer SDK (CLI + REST) for managing stablecoin flows in apps
Multisig Controller Module
Aiken-based governance contracts for cooperatives, DAOs, shared custody
ADA On and Off Ramps Giving users the access to USDA in the frontier markets
These modules will power both developers and real-world applications, with pilots focused on Africa and MENA, where Encryptus already supports fiat flows in 130+ countries.
FusionFi Core helps Cardano achieve its mission of programmable, inclusive finance through composable, production-grade infrastructure.
Problem Statement
Cardano currently lacks standardized, modular infrastructure for building real-world DeFi applications, such as lending protocols, stablecoin integrations, and fiat gateways. Developers are forced to build from scratch, with no reusable smart contracts, SDKs, or governance modules available within the ecosystem. There is a clear need for a unified toolkit that provides the foundational backend for DeFi and real-world asset (RWA) use cases, and that aligns with the priorities of Cardano’s commercial roadmap: including stablecoin adoption, institutional-grade DeFi, and bridges between Web3 and traditional finance. This gap is especially urgent in regions primarily Africa and Middle East and some other frontier markets, where Cardano has committed to driving economic inclusion. Builders and users in these markets need access to infrastructure for fiat-backed lending, shared asset management (via multisig), and stablecoin-based wealth preservation: all of which remain difficult to implement without open, reusable modules.
Proposal Benefit
FusionFi Core provides open-source infrastructure that helps the entire Cardano community:
Lending contracts (Aiken) to accelerate protocol development
USDA integration wrapper to support stablecoin adoption across dApps
Multisig controller module to power community savings, cooperatives, and DAOs
Real-world deployment in Africa and MENA to validate global use
This empowers builders, strengthens Cardano’s DeFi ecosystem, and fulfills the network’s mission of programmable, inclusive financial access, in line with the Cardano Commercial Roadmap.

I can not support funding any projects from Emergo until they provide transparency on what results were obtained from the 2 Billion ada they were given to develop commercial adoption with the genesis funding, what ada is remaining, and what do they consider completed and what is unfinished in their initial remit.
To date they have acted as an unreliable supplier with little to no transparency on their funding, KPI completion and ROI vs what they were paid, so giving them more money before this is rectified doesn’t make sense.
The FusionFi Core project fills critical gaps in the Cardano ecosystem by providing standardized lending, stablecoin, and multisig infrastructure. Its open-source and modular design is particularly interesting as it brings value to the global community while allowing developers to adopt only the functions they need. The pilot implementations in Africa and MENA regions contribute to Cardano's mission of economic inclusion, while USDA integration will promote TVL growth and capital inflow.
I think the wider Cardano ecosystem needs to support such initiatives as they will take Cardano more main stream by lowering the barrier for developers to build on the chain. If there are some concerns around how this particular proposal is put together, consensus can be achieved through honest dialogue. Otherwise this is a good proposal to have in the Cardano budget as far as I can see.
"Thank you 🙏
- Since this will be an open source tool that will benefit the entire Cardano community, is it possible to secure recommendations from prominent developers in the community who will actually use this, that this is something they would like to use and not something that has already been developed?
It would be great to secure such recommendations from, for example, Liqwid or AADA. Can you include interviews with them?
This will ensure that there is no overlap with any tools they have publicly or in-house, and that it will be useful to at least prominent lending protocol developers in the broader Cardano community.
- I think this proposal has not been socialized enough yet. I haven't seen any X or anything like that disseminating this proposal and the community actively providing feedback. Also, I'm the only one commenting on Govtool. What are your plans for how to do this going forward?"
-
Is it possible to actively share this proposal on various Cardano community social media platforms, such as X, to adequately socialize the proposal and gather feedback?
-
The proposal projects over 100 integrations and a TVL of $900M by 2030. Considering Cardano’s historical growth rate and competition from other blockchains, is this forecast realistic?
-
The proposal estimates a total budget of about $1.16M (1,666,667 ADA), which is quite substantial. How does this compare to similar projects’ development costs, and what measures are in place if the budget is exceeded?
-
The proposal involves fiat integration and USDA stablecoins. How does the team plan to address varying financial regulations and compliance requirements across different jurisdictions?
-
The proposal relies heavily on USDA. If USDA faces liquidity constraints or limited adoption, how would this affect the project’s overall viability and value proposition?
-
The proposal offers a multisig and DAO governance module. What measures are in place to mitigate risks stemming from improper use (e.g., lost keys, delayed consensus) by the end users?
-
The proposal states that EMURGO Labs will handle maintenance and upgrades. How will the project ensure sustainable operations, including long-term funding and community-driven governance?
-
The proposal’s TVL model uses a 1.5× collateral assumption based on loan volume. What incentives or liquidity requirements ensure that users keep collateral locked over time?
-
Can you define performance KPIs and target values upon completion of this proposal?
