According to the official announcement from NULS, the platform has successfully completed the inter-chain integration of Bitcoin (BTC) and Ethereum (ETH) native assets, passing rigorous testing. The core objective of this project is to enhance network efficiency and user experience, particularly through the introduction of BTC and ETH as payment methods for Gas fees. As the code is about to be integrated into the mainnet, NULS will become the first public chain to achieve this function, further increasing its competitiveness in the cryptocurrency industry. This innovation not only provides users with more choices, allowing them to flexibly use different cryptocurrencies for transactions and paying Gas fees, but also means that NULS's node operators and Stakers can earn revenue from these transactions. This not only increases the economic incentive mechanisms of the network, but also promotes the continuous development of the ecosystem. NULS's upgrade is not only a demonstration of its technical strength, but also a pioneering exploration of the future direction of the blockchain industry. By supporting multiple assets as Gas fees, NULS provides new possibilities for building an open, efficient, and compatible cryptographic ecosystem, which is of great significance for driving the progress of the entire industry.
