# suix\_getCoins{deprecated} - Sui

This method returns all Coin objects of a specific type owned by an address on the SUI network. This filtered version of `suix_getAllCoins` is more efficient when you only need coins of a particular type, such as SUI for gas payments or a specific token for transfers. It supports pagination for addresses with many coin objects.
