Below is a well-deserved Q2 update highlighting ecosystem tooling and solutions across April, May, and June.

The past three months have been all about tightening up infrastructure, enhancing developer tools, and shipping valuable updates to support the Cardano ecosystem. With over 90 pull requests merged and 60+ issues closed in June alone, it’s been a highly productive quarter. Check out the highlights below to see what’s been delivered.

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 interview, Kristian Portz, co-founder of Masumi Network, explains how the platform builds infrastructure for AI agents to work together, make decisions, and handle payments autonomously - while staying secure and compliant with European regulations. Built on the Cardano blockchain, Masumi creates transparent systems where agents interact without human input. Portz highlights real-world use cases in finance and healthcare and considers how AI agents might shape future governance, marking a shift in technology collaboration. Sounds Exciting? Well..let’s dive right in!

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.

In this interview, Rusty, also known as fallen-icarus on X, shares his vision for a truly decentralized financial system. He discusses the flaws in today’s DeFi models, which often rely on centralized mechanisms, and explains why a shift to P2P DeFi is necessary. Rusty breaks down key concepts like liquidity sharing, UTXO contention, and free-market solutions, offering a fresh perspective on making DeFi more scalable, efficient, and accessible. To learn more about the P2P DeFi solution Rusty proposes, check out the full interview below.

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.
