ParseMint

Parse a mint account’s on-chain state — including authority, decimals, supply, token program, and Token-2022 extensions.

ParseMint reads a mint account and returns its structured state. It detects whether the mint belongs to the SPL Token or Token-2022 program and returns the appropriate extension or metadata data.

ParseMint is a query method — it does not return a SolanaInstruction. No transaction is needed.

Request

account_address · Base58-encoded public key (string) · required

The mint account address to parse.

Response

mint · MintInfo (object) · required

Core mint account fields.

Show MintInfo fields

mint_authority_pub_key · Base58-encoded public key (string)

Authority that can mint new tokens. Empty if mint authority has been revoked.

freeze_authority_pub_key · Base58-encoded public key (string)

Authority that can freeze token accounts. Empty if freeze is disabled.

decimals · uint32

Decimal precision of the token.

supply · string

Current total supply in base units. Returned as a string to avoid integer overflow for high-supply tokens.

is_initialized · bool

true if the mint account has been initialized.

token_program · TokenProgram (enum) · required

Indicates which token program owns this mint. Either TOKEN_PROGRAM_SPL_TOKEN (legacy SPL Token) or TOKEN_PROGRAM_TOKEN_2022 (Token Extensions). See TokenProgram.

extensions · Token2022Extension[] (repeated)

Token-2022 extensions configured on this mint. Empty for SPL Token mints.

metaplex_metadata · MetaplexTokenMetadata (object)

Metaplex on-chain metadata. Only present for SPL Token mints that were created with CreateSPLTokenMint and included metadata.

Show MetaplexTokenMetadata fields

name · string

Token name.

symbol · string

Token symbol.

uri · string

URI pointing to off-chain metadata JSON.
