In this session of the Cardano Developer Office Hours, Giovanni Gargiulo, Senior Software Engineer – DevOps at the Cardano Foundation, presents the new Token Registry API v2 with full CIP-68 support. He demonstrates API endpoints, explains best practices for using the query_priority parameter, and covers support for tokens under both CIP-0026 and CIP-0068. A live demo shows practical use cases and integration opportunities for developers.
In this session of the Cardano Developer Office Hours, Fabian Bormann, Team Lead of Ecosystem Engineering at the Cardano Foundation, presents UVerify, a lightweight tool for certifying and verifying data on Cardano without tokens or NFTs. He covers datums as an alternative to metadata, SDKs and white-label tools for devs, and real-world use cases like documents, credentials, and oracles. A live demo shows UVerify in action. The roadmap explores frictionless integrations and future opportunities for verifiable interactions across ecosystems.
In this session of the Cardano Developer Office Hours, the team presents PoP (Proof of Provenance), a project to decentralize open-source development on Cardano. They cover risks of centralized infrastructure, using Cardano for verifiable software metadata, Merkle trees, and on-chain tracking. A live demo shows PoP in action. Use cases include secure versioning, on-chain test management, SPOs as decentralized oracles, and decentralized package tools.
Alex Nemish and Oleksii Khodakivskyi from Lantr introduce Scalus, a smart contract framework built with Scala 3. They walk through the vision, roadmap, and show how it simplifies development on Cardano, including a live demo of a payment splitter contract. This session is ideal for devs exploring new tools to build on Cardano.
Giovanni Gargiulo, Senior Software Engineer at the Cardano Foundation, shares how ecosystem engineering supports Cardano’s growth. The session covers DevOps practices behind scalability, security, and uptime, along with challenges of running decentralized infrastructure. Giovanni also touches on infrastructure evolution, global adoption, and what’s ahead for Cardano engineering.
Satya Ranjan, Lead Blockchain Architect at the Cardano Foundation, presents Java tools for building on Cardano. The session covers cardano-client-lib, writing off-chain code, building transactions, and integrating governance and staking. Satya also demos Yaci DevKit for local dev environments, Yaci Store for indexing, and shows how to build lightweight apps using tailored data. Ideal for developers and exchanges exploring Java’s role in Cardano infrastructure.
This installment of the Cardano Developer Office Hours explores Reeve, a next-generation accountability tool for delivering tamper-proof and transparent financial insights. Reeve integrates traditional accounting systems with blockchain technology, ensuring transparency, immutability, and security for financial records. Built on Cardano, the platform offers a decentralized approach to financial data management. Designed for accountants, auditors, non-profits, and enterprises, Reeve helps streamline audits, improve efficiency, and build trust in financial processes. The session provides an overview of the project, its architecture, and current development.
This installment of the Cardano Developer Office Hours explores the Cosmos-Cardano Inter-Blockchain Communication (IBC) bridge project. The session provides an overview of the architecture, current development, and key components driving the project. Topics include the IBC protocol, blockchain interoperability, and the integration of Cosmos SDK with Cardano. A live demo showcases how to send messages between the Cosmos network and a local Cardano node. The session also covers real-world use cases like token transfers, cross-chain swaps, and more.
This 13th installment of the Cardano Developer Office Hours is presented by Thomas Kammerlocher, Senior Full Stack Developer at the Cardano Foundation. Thomas discusses the Java implementation of Rosetta, a tool developed by Coinbase for exchanges to integrate with Cardano. Rosetta simplifies multi-chain support with its blockchain-agnostic API, and the transition from TypeScript to Java enhances performance and reduces resource consumption. Upcoming updates include support for staking rewards tracking, off-chain data integration, and more improvements to scalability and efficiency.
This 12th installment of the Cardano Developer Office Hours is presented by Satya Ranjan, Senior Enterprise Architect at the Cardano Foundation. In this session, Satya discusses how the yaci-devkit simplifies building and testing on a local Cardano dev network, helping developers iterate faster and avoid public testnet limitations. The session highlights key features such as customizable block times, integrated tools, and Blockfrost-compatible APIs. A live demo shows easy setup using Docker and NPM distributions.
