Snakes are a vital component of wildlife resources and are widely distributed across the globe. The many-banded kraitBungarus multicinctusis a highly venomous snake found across Southern Asia and central and southern China. Snakes are an ancient reptile group, and their genomes can provide important clues for understanding the evolutionary history of reptiles. Additionally, genomic resources play a crucial role in comprehending the evolution of all species. However, snake genomic resources are still scarce. Here, we present a highly contiguous genome ofB. multicinctuswith a size of 1.51 Gb. The genome contains a repeat content of 40.15%, with a total length exceeding 620 Mb. Additionally, we annotated a total of 24,869 functional genes. This research is of great significance for comprehending the evolution ofB. multicinctusand provides genomic information on the genes involved in venom gland functions.
