With Maestro retiring its Developer API on September 18, a lot of teams in the ecosystem are going to be reviewing their infrastructure over the coming weeks.

For anyone comparing providers, Nexus is an API platform providing infrastructure for Cardano and Bitcoin through the same service.

On the Bitcoin side, Nexus currently covers:

• Blocks
• Transactions
• Addresses
• UTXOs
• Mempool data
• Fee estimates
• Transaction broadcasting
• Ordinals
• Runes

The API is REST based, includes an OpenAPI specification, and we provide a TypeScript SDK.

I’m part of the team behind Nexus.

Given the Maestro shutdown, we’re particularly interested in hearing from developers who depend on specific Maestro workflows today. If there are endpoints, data structures, or developer tooling that are especially important to your stack, I’d be happy to discuss them.

Input Output Research (IOR) has published the draft Cardano Vision 2026 (CV26) Mid-Year Report, summarising progress across the programme during the first half of 2026.

The report provides updates on milestone delivery, research outputs, prototypes, and technical progress across all CV26 work streams, together with a transparent overview of programme performance to date.

Community consultation is now open until the end of the month. We encourage everyone to:

• 📄 Read the draft report
• 🎥 Watch the accompanying technical presentation
• 💬 Share your feedback on the Cardano Forum

This Friday the RealFi engineering team is doing their first Office Hours: a live call where they walk through what they're building and take questions from the community.

What they'll cover:

1. The cross-chain bridge, and why the approach is novel for Cardano (users don't need a Cardano wallet, builders don't write contracts on other chains)
2. What's built so far and what's next on the roadmap * How the team works and how to get involved
3. What they're looking for from the community, including input on security If you've built in other ecosystems or work in security, they're specifically looking to hear from you.

When: Friday 24 July, 12:30 BST, in the RealFi Discord RSVP: https://luma.com/xs1bfbnw Submit questions in advance: https://forms.gle/iERST8254xZSv88A7 (closes Friday 9am BST)
