On July 17th, the OKX Web3 Runes market engraving function added support for merging runes, reducing the cost of user casting and simplifying the process of rune listing. Users can freely choose to engrave as, merge runes, or original independent runes when engraving. Compared with casting an independent rune each time, users can save up to 29% of gas costs by merging and casting into one rune. For example, in standalone rune mode, if a user Mints 20 A runes, they will get 20 A runes. In combined rune mode, if a user Mints 20 A runes, they will get 1 20 A rune.
