The OKX Web3 Runes Market Engraving function now supports merged runes, which reduces the cost of casting for users and simplifies the process of listing runes. Users can freely choose to engrave as merged runes or original independent runes. Compared with casting as an independent rune each time, users can save up to 29% of gas fees by merging and casting into one rune. For example, in the independent rune mode, if the user mints 20 A runes, he will get 20 1-piece A runes. In the merged rune mode, if the user mints 20 A runes, he will get 1 A rune of 20.
