Nubila, a global physical AI network project, has partnered with Solayer to launch a sale of Validator Nodes, running until October 1st. The sale is exclusively available through Solayer's Web3 payment tool, Emerald Card, which offers cardholders exclusive benefits and priority credit limits. The sale features three node tiers—Cloud, Rainy, and Sunny—each limited to 500 units, with varying reward levels. Purchasers using the Emerald Card can earn sNUBI points and $LAYER bonuses. This initiative not only positions Emerald Card as a key payment partner within the Nubila ecosystem but also allows users to participate in building core infrastructure for real-world data on-chain, AI, and DeFi. Nubila and Solayer aim to further explore crypto payment applications in daily consumption, enhancing Web3 payment experiences. With limited nodes available, early participation is encouraged to maximize rewards and future value.
