**[Nubila and Solayer Launch Joint Validator Node Sales Campaign]** The global Physical AI network project Nubila has announced a partnership with Solayer to officially launch Validator Node sales. The campaign runs until October 1, and users can exclusively participate through Solayer's Web3 payment tool, the Emerald Card. Cardholders will enjoy exclusive benefits and priority quotas during on-chain activities. This collaboration not only establishes the Emerald Card as a payment method but also expands its role as a key payment partner within the Nubila ecosystem. The sales offer three tiers of nodes: Cloud Node, Rainy Node, and Sunny Node, each limited to 500 units. Different node tiers correspond to varying reward levels, and users purchasing through the Emerald Card will receive sNUBI points and LAYER reward bonuses. Nubila stated that operating Validator Nodes not only provides long-term ecosystem incentives but also signifies direct user participation in the core infrastructure of real-world data on-chain, AI, and DeFi. Additionally, Nubila and Solayer will continue to explore more application scenarios for crypto payments in everyday consumption, driving the adoption and innovation of Web3 payment experiences. As the countdown progresses, node availability is limited—early participation secures greater rewards and future value.
