Notice of Closure After careful consideration, Horizon Protocol/Xpanse has made the difficult decision to cease operations. Despite sustained development efforts over the past five years, the project has not been able to achieve sustainable returns. It now faces significant and escalating financial challenges, and no remaining runway is available to support continued operations. While the project has operated in a very lean way to maximize its runway and chances, ultimately the project has been unable to establish a reliable revenue stream or secure new investment. Consequently, the project team has reached a collective decision to wind down operations. A detailed timeline, along with instructions for users with active positions across our dApps, will be provided shortly. To our community, supporters, and partners — thank you for being part of our journey. We are deeply grateful for your belief in the vision of Horizon Protocol/Xpanse and wish you continued success in the future. Horizon Protocol/Xpanse

Project Status Update Over the past few months, the project has been in discussions with multiple investors; however, nothing has been confirmed at this time. Xpanse is currently operating in a maintenance mode to reduce costs and ensure a stable and continuous product functionality. We will provide further updates when new information becomes available.

Information regarding MEXC Exchange delisting HZN. Despite our efforts to add additional liquidity, the MEXC team has informed us that the liquidity levels have not consistently met their internal requirements.

We remain focused on building and progressing as planned. Next up will be launching more AI powered trading signals on Xpanse perpetual futures.

Attention Stakers: Grace Period Extended To 24h We’re extending the grace period window based on community feedback and concerns. So here’s what’s changing: We’re increasing the liquidation grace period from 12 hours to 24 hours. This gives stakers more time to react if their C-Ratio drops below 160% and get flagged for liquidation. Key points to know: - A staker gets flagged as soon as their C-Ratio drops below 160%. - Even if the price later moves in their favor and their C-Ratio rises above 160%, they remain flagged until they manually restore their ratio to a safe level. - Once flagged, the staker has 24 hours to fix their position before they're at risk of liquidation. The staking UI shows a staker’s status: if they are flagged, it will say “Flagged for Liquidation” as shown in the attached screenshot. This is pulled directly from the smart contracts, ensuring that the information displayed is always up to date. The new UI was designed to be more trader-focused and does not include a bell icon; if you prefer the bell, you can continue using the old UI. Stay safe: keep an eye on your status, not just your C-Ratio.

Xpanse AMA Recap: Multi-Liquidity, AI Trading, HZN’s Future & More We recently hosted an AMA to share exciting updates about Xpanse—an expansion of Horizon Protocol. Xpanse introduces new liquidity models, AI-driven trading, and enhanced revenue mechanisms to accelerate growth and sustainability. Key Highlights: - Xpanse is an expansion, not a rebrand: While Horizon Protocol remains a core part of the ecosystem, Xpanse builds on it with AI-driven trading, multi-chain integration, and additional liquidity layers to enhance accessibility and adoption. - Revenue Generation: 40% of revenue from intent-based trading will go to HZN stakers, and another 40% will support buybacks and burns. These percentages are proposed and will be open for community discussion. Additional revenue will come from AI-driven services like trade signals. - Buybacks, Burns & Treasury Management: Starting in March 2025, we’ll initiate weekly buybacks and burns to strengthen HZN’s value. The revenue split will evolve based on the global active C-Ratio, balancing rewards for stakers and ongoing platform growth. - Future Developments: AI-powered trading competitions, multi-chain integrations, and new asset listings are on the horizon. Xpanse is designed to create sustainable growth, and generate value for Horizon Protocol and its community. Stay tuned for more updates!
