At Breakpoint 2023, Adam and Sylvie introduced Solatening, a pioneering development in the cryptocurrency space: a fully trustless, cross-chain decentralized exchange (DEX) that bridges Bitcoin and Solana, allowing users to make instant payments and swaps between the two. Amidst the vibrant cityscape of Amsterdam, the founders demonstrated the practical applications of Solatening, showcasing how it can be used for day-to-day transactions like buying coffee. They expounded on the seamless nature of transactions, the security of the underlying technology, and the trustless nature of the swaps—highlighting the significance of such features in the post-FTX era.

Key Points:

Solatening: Bridging Bitcoin and Solana

Solatening emerged as an innovative solution to enable payments with Solana in places where only Bitcoin is accepted, particularly through the Bitcoin Lightning Network, which is already quite prevalent. Adam and Sylvie highlighted Solatening’s role in bridging the two significant cryptocurrencies, allowing for fast and trustless payments and swaps. This new use case simplifies transactions by allowing Solana holders to pay at Bitcoin Lightning-enabled merchants seamlessly.

The Practical Demonstration

The co-founders of Solatening shared their personal experience using the platform. They described the process of paying for coffee at a local café in Amsterdam, utilizing the Solatening DEX through their Phantom wallet. The demonstration highlighted the speed and ease of the transaction, underscoring the potential of Solatening to bridge the gap between different blockchain ecosystems and bring about greater adoption of cryptocurrency in daily commerce.

Trustless Cross-Chain Swaps

Adam explained the technicality behind the trustless cross-chain swaps. He showcased two different ways to swap between Bitcoin and Solana: via the Bitcoin Lightning Network for lower-value, quick swaps, and using on-chain transactions for larger trades. The importance of trustless exchanges was stressed, especially in the wake of failures of centralized entities like FTX. Adam also gave a live demo of the swapping process on their DEX.
