# suix\_getCoinMetadata{deprecated} - Sui

This method returns metadata for a specified coin type on the SUI network, including its symbol, decimals, name, description, and icon URL. This information is essential for displaying tokens correctly in wallet interfaces, DEXs, and portfolio trackers. The metadata is stored on-chain and reflects the token's official configuration.
