The process of changing an identity on Solana is governed by the Metaplex Metadata Program. Every SPL token's identity lives in a
MetadataV3 account. To change the logo, you must execute an UpdateMetadataAccountV2 instruction. This instruction takes a DataV2 structure which includes the name, symbol, and uri. It is important to note that you cannot change the Mint Address; you are only changing the 'Label' that wallets display for that address. Solatify's terminal handles the complex byte-packing and account derivation needed to target the correct Metadata PDA, ensuring your update is technically perfect and compatible with the latest Mainnet-Beta protocol rules.
