NULS has announced that it has completed the cross-chain integration and testing of BTC and ETH native assets, and plans to merge the code into the main network in the near future. After the upgrade is completed, users can directly use BTC and ETH as Gas fees on the NULS network. Both NULS nodes and Stakers will receive profits from network Gas fees. This move makes NULS the first public chain to support multiple assets as main network Gas fees, marking an important innovation.
