<br>Community Innovation Funding & Infrastructure</a></td><td>The Supplier will run a grants program known as Project Catalyst, which includes inviting
interested parties to submit proposals as part of three funding rounds (Fund 14, Fund 15, and
Fund 16). The Supplier, through its appointed administrator, will provide a platform to support
the program, manage its operations and carry out all necessary activities to ensure the effective
execution of the program—from fund launch through to project reporting.</td><td>64,300,000</td></tr><tr><td>Cooperativa de Trabajo Eryx LTDA</td><td><a href="https://drive.google.com/file/d/1eAL3X-vaEGceL7p-TQQZLulTk8WT50Uu/view?usp=drive_link">ZK Bridge</a></td><td>This Grantee will build a ZK bridge for Cardano, which Grantee will deploy on the Cardano
testnet.
As part of this initiative, Grantee will define a communication protocol for the bridge, provide
the full source code of the smart contracts on the Cardano side, and produce comprehensive
technical documentation detailing the protocol between Cardano and any other isomorphic
blockchain.</td><td>700,000</td></tr><tr><td>Dmytro Stashenko</td><td><a href="https://drive.google.com/file/d/1HLCg8S5qP4VDlgslYG6iDSDbwxkCeuUE/view?usp=drive_link">AdaStat.net Cardano blockchain explorer</a></td><td>We propose to continue development and support of the AdaStat.net Cardano

Cardano data node implies a subset of features of a full node, mainly the ability to follow the
tip of the chain and update the local ledger state accordingly, while replaying to queries from
the end user. The ability to have a data node in the browser minimizes the trust required to
<br>interact with the cardano blockchain from any app that uses it.</td><td>578,571</td></tr><tr><td>Informatik Mündler</td><td><a href="https://drive.google.com/file/d/1I7XNaLhNuNUpHi3I69F_U3gihT5TNgO0/view?usp=drive_link">OpShin - Python Smart Contracts for Cardano</a></td><td><p>OpShin is a toolchain that lets developers construct Cardano smart contracts in Python. The
toolchain comprises several projects that aim to facilitate the development of Smart
Contracts and dApps on Cardano. They are largely based on Python, or integrate well with it
for maximal accessibility. On top of accessibility, OpShin ensures low transaction cost
compared to PlutusTx. </p><p>
<br>OpShin enforces strict typing on the high-level programming: it implements a type system on
top of Python type hints. However, all traces of typing are erased during compilation, for a
maximum efficiency program. OpShin beats many programming languages when taken to
<br>the test for real use-cases.</p></td><td>199,911</td></tr><tr><td>IOE</td><td><a href="https://drive.google.com/file/d/1B7JOGsD5xwefRmcZvAfEDTN8R79qWz1Z/view?usp=drive_link">2025 Input Output Engineering Core Development Proposal</a></td><td>The Supplier will provide comprehensive engineering, maintenance, and development services to enhance and secure the Cardano protocol and its core infrastructure.
