Hello Sundial community! Below is our latest Sundial update.

🍎Industry Insights

The blockchain industry in mid-2025 is entering a phase of measured institutional adoption, driven by clearer regulatory frameworks, maturing infrastructure and increased focus on risk-managed, scalable architecture. Layer‑2 solutions, cross-chain bridges, and DeFi protocols are now being evaluated as serious financial primitives by funds, fintechs and central banks.
Recent regulatory developments such as DeFi broker-reporting rules in the U.S. and advancement of the CLARITY Act signal that policymakers are beginning to understand the unique operating models of decentralised systems, reducing legal uncertainty.
From an investment standpoint, attention is shifting toward projects that combine modular architecture, compliant onboarding, and real-world utility. Fixed-income DeFi and institutional custody layers are seeing sustained capital flows. Sundial’s as an institutional-grade Bitcoin DeFi Layer‑2 on Cardano directly aligns with these trends, offering investors exposure to both technical innovation and regulatory alignment.

🛬Sundial at Rare Evo

We’re thrilled to announce that Sundial, the pioneering optimistic rollup network for Bitcoin and Cardano, will be joining Rare Evo 2025. As the first Layer 2 of its kind on Cardano, Sundial is redefining scalability and utility for UTxO-based chains. Expect deep dives into fraud-proof architecture, censorship resistance and how Sundial is unlocking yield and interoperability for trillions in dormant crypto assets at our pop up. Don’t miss this chance to engage with the team behind one of the most ambitious Layer 2 projects of the year.

🤝Sundial Partners with Appold, Who Announce a Founding Stake in the Protocol.

Appold, the London-based blockchain advisor, has announced a Founding stake in Sundial Protocol in a move set to bring compliant Bitcoin yield infrastructure to the forefront.

This collaboration follows a historic technical milestone: The world’s first bridgeless cross-chain Bitcoin transfer between Bitcoin and Cardano blockchains, successfully executed in May 2025, enabled by Sundial’s infrastructure and partnerships.

“We’re building infrastructure to unlock a new phase of Bitcoin yield which is secure, programmable, and accessible,” said Sheldon Hunt, CEO of Sundial Protocol. "Appold brings the expertise to ensure we grow with strong governance and institutional credibility.”

“The demand for trusted, compliant Bitcoin infrastructure is rapidly growing,” added Robert Gaskell, Founder & Partner at Appold. “Sundial’s approach combines innovation with the institutional standards that markets now expect.”

🧑‍💻Sundial x Anastasia Labs

We’re excited to spotlight our collaboration with Anastasia Labs, the technical force behind Sundial’s architecture. Built as a hybrid Layer-2 on Cardano, Sundial leverages Midgard, Anastasia Labs’ high-performance execution framework.

Anastasia Labs, a leading smart contract development and audit firm, also played a key role in developing Sundial’s Bitcoin bridge, pushing forward our mission to unlock native BTC liquidity in the Cardano ecosystem. The partnership is recognised in Cardano’s official project documentation and is a cornerstone of our technical foundation.


📌Sundial x Fluid Tokens

We’re thrilled to announce our partnership with Fluid Tokens, a pioneer in real-world asset (RWA) lending on Cardano. This collaboration brings RWA collateral to Sundial’s hybrid Layer-2, enabling users to tap into on-chain liquidity using off-chain assets.

By integrating Fluid Tokens with Sundial’s high-performance execution layer, we're opening new doors for secure decentralised lending markets with native BTC access via Sundial’s bridge.

👋 Hello everyone, below are some of the recent updates for Sundial Protocol


📚Sundial Completes the Draper University program

Sundial has officially completed the Cardano x Draper University Founder Residency Program. Over five intense weeks in Silicon Valley, our team accelerated development, forged powerful partnerships, and gained rapid feedback from mentors and builders across the Cardano ecosystem. A huge thank you to the Cardano community, Catalyst, DraperU and Yaad Labs for making it possible.

🛣The Sundial Roadmap is available on our Website

📢BTC Layer 2s are mentioned by Michael Saylor during his BTC Prague talk.

BTC Prague 2025 brought together over 10,000 attendees and 200+ speakers for Europe’s largest Bitcoin-focused event. A major highlight was Michael Saylor’s keynote, a compelling articulation of Bitcoin’s long-term value to date.

Saylor positioned Bitcoin as a foundational layer of economic energy that surpasses even the most dominant tech monopolies in resilience and decentralisation.

📖Sundial x Torram Case Study

Sundial is scaling Bitcoin with Layer 2 rollup technology — and now, it’s partnering with Torram to anchor fraud proofs, smart contracts, and data availability directly onto Bitcoin’s base layer. By combining Torram’s Bitcoin-native middleware with Sundial’s optimistic rollup architecture, this collaboration unlocks a new era of secure, scalable, and programmable DeFi on Bitcoin. Read the full breakdown of how this partnership brings trustless interoperability and institutional-grade infrastructure to BTC. Check it out here.
