# suix\_resolveNameServiceAddress{deprecated} - Sui

This method resolves a SuiNS (Sui Name Service) name to its corresponding SUI address. SuiNS provides human-readable names like `example.sui` that map to SUI addresses, similar to ENS on Ethereum. This method enables wallet applications and dApps to accept user-friendly names instead of hex addresses.
