Unlocking the DeFi Opportunities Available on Sundial

Bitcoin is currently an underutilised asset with a substantial portion of its circulating supply having sat unmoved for over a year, and a growing share untouched for five years or more. The inability to put this Bitcoin to productive use has left billions of dollars in value sitting idle, contributing nothing to its holders beyond long-term price appreciation. Sundial changes that equation by unlocking productive use cases for Bitcoin without requiring holders to compromise on the security and self-custody principles that make Bitcoin valuable in the first place.

Dawn: A New Standard for Bitcoin Yield

For most of Bitcoin’s history, holders have faced a binary choice: let your BTC sit unproductively in cold storage or move it off-chain into ecosystems that require trusting a third party. Dawn, Sundial’s flagship yield product, was built to close that gap.

Dawn is a Bitcoin locker built entirely on pure Bitcoin scripts. This means it operates natively on Bitcoin Layer 1 without wrapping BTC into a synthetic representation or routing it through a separate chain to generate returns. Through Dawn, users lend their Bitcoin into yield strategies that Sundial has independently vetted and verified at the Layer 1 level, allowing holders to put dormant capital to work while keeping the entire process anchored to Bitcoin’s own security guarantees.

What sets Dawn apart is the philosophy behind its design: rather than forcing every user into a single fixed strategy, Dawn is built for our flexible yield marketplace where individuals can choose their own balance of customisation and risk. Instead of adopting a one-size-fits-all approach to Bitcoin staking, we let each user choose their level of security.

Central to this flexibility is Dawn’s stop-limit feature, which gives users direct control over their downside. Users can define in advance exactly how much they’re willing to risk losing, and if the value of their staked position falls below that threshold, their funds are automatically returned to them. This turns Bitcoin yield generation from an open-ended risk into a bounded one, giving holders the confidence to participate in yield strategies without exposing themselves to unlimited downside.

The broader significance of Dawn lies in what it represents for Bitcoin as a whole. Bitcoin has long been criticised as ‘unproductive’ capital compared to yield-bearing assets in traditional finance or programmable ecosystems like Ethereum. Dawn challenges that narrative directly by proving that Bitcoin can generate real yield. By building yield infrastructure natively on Bitcoin Layer 1 rather than bridging BTC away from its home chain, Dawn allows holders to participate in DeFi-style yield generation while keeping their Bitcoin exposure on Bitcoin itself.

Alchemy: Fully Trustless Bitcoin Treasury Exposure

Bitcoin treasury companies have become one of the most talked-about vehicles in the industry over the past few years, offering investors indirect exposure to Bitcoin’s upside through publicly traded equities. However, this model comes with an inherent trade-off: to participate, investors have to step out of Bitcoin entirely and into the traditional stock market and take on the associated risks.

Alchemy, built by Sundial in partnership with Charms, reimagines the Bitcoin treasury model as a fully trustless, on-chain alternative that requires no interaction with traditional stock markets whatsoever. Rather than relying on a company to manage a treasury on investors’ behalf, the entire mechanism in Alchemy is handled programmatically through the Charms metaprotocol and its zero-knowledge (ZK) proof system. This means the treasury logic itself is enforced by code and cryptographic proofs, giving users a way to gain treasury-style exposure without ever leaving the Bitcoin ecosystem or handing custody to a third party.

Within Alchemy, users can choose between two distinct assets, each designed for a different type of investor.

• Fire is for those seeking higher-volatility yield who are comfortable with larger swings in exchange for greater speculative upside.
• Ice is for those who prefer consistency in a lower-volatility asset that delivers steady, predictable payouts.

Together, Fire and Ice allow users to select their exposure based on their own risk appetite, rather than being forced into a single, undifferentiated treasury product.

The significance of Alchemy extends beyond the yield it offers. Traditional Bitcoin treasury companies reintroduce exactly the kind of centralised, trust-based risk that Bitcoin was built to remove, as investors are ultimately betting on a company’s governance and solvency, not just Bitcoin itself. Alchemy strips that layer of trust out entirely by replacing it with a transparent ZK-secured system that lives natively alongside Bitcoin. In doing so, it offers the market treasury-style Bitcoin exposure that doesn’t ask investors to leave Bitcoin’s trust model behind in order to get it.

Solstice: Bringing Real-World Value Onto Bitcoin

Despite Bitcoin’s strength as a settlement layer, one of its long-standing limitations has been its isolation from the broader universe of assets and yield opportunities that exist off-chain. Solstice was built to close that gap.

Solstice is Sundial’s tokenised vault solution, designed to take off-chain assets and bring them on-chain directly onto Bitcoin Layer 1. In practice, this means real-world assets and financial instruments that have traditionally lived outside of crypto entirely can be represented as tokens secured by Bitcoin’s own settlement layer. Solstice extends the same principle to yield itself: off-chain yield strategies can be tokenised and issued directly on Bitcoin L1, giving holders a way to gain exposure to that yield without ever leaving the Bitcoin ecosystem.

What makes Solstice particularly significant is the direction it points Bitcoin’s future utility toward. Rather than treating Bitcoin purely as a destination for Bitcoin-native activity, Solstice positions Bitcoin Layer 1 as a settlement and custody layer for a much broader category of value. This is a meaningfully different proposition from wrapped-asset models on other chains, which typically require users to trust a separate bridge or custodian. By settling directly on Bitcoin L1, Solstice keeps that value anchored to the most secure and battle-tested chain in existence.

The demand for this kind of infrastructure is already evident. Solstice has attracted significant interest from companies looking for a credible way to bring their assets or yield products on-chain, reflecting a broader institutional appetite for tokenisation that has, until now, lacked a natural home on Bitcoin. As that interest translates into real deployments, Solstice has the potential to meaningfully expand the use cases for Bitcoin Layer 1.

Conclusion

Dawn, Alchemy and Solstice each tackle the same underlying problem from a different angle: Bitcoin’s vast pool of capital has long sat idle, valued for its security but rarely put to productive use. Dawn offers yield with self-defined risk, Alchemy provides trustless treasury exposure, and Solstice brings real-world assets on-chain. Together, these products reflect a broader shift already underway: Bitcoin becoming a foundation for productive, programmable finance rather than a purely passive store of value. Sundial is building the infrastructure to make that shift real.
