Create Mint

Build the complete instruction set to create and initialize a Token-2022 or SPL Token mint account in one call.

Both methods return the complete ordered instruction set needed to create a mint — you don’t need to separately query rent, build a System Program create instruction, or initialize the mint. The key difference is which token program the mint belongs to: Token-2022 supports extensions (like metadata); SPL Token supports Metaplex metadata via a separate program.

Not sure which token program to use? See Token Programs for the trade-offs.

These methods return instruction lists. Add them in order to a transaction and use the Transaction Service to compile, sign, and submit. See Instructions & Transactions.

CreateToken2022Mint

Creates and fully initializes a Token-2022 mint in one call. Returns the complete ordered instruction set: System::CreateAccount → extension pre-init instructions → initialize_mint → extension post-init instructions (e.g. token metadata, update fields).

Request

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

Pays for account creation. Must be a signer.

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

The mint account to create. Must be a signer (new keypair).

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

The authority that can mint new tokens.

freeze_authority_pub_key · Base58-encoded public key (string)

Optional. Authority that can freeze token accounts. Omit to disable freeze.

decimals · uint32 · required

Decimal precision. Common values: 9 (SOL-like), 6 (USDC-like), 0 (NFTs).

extensions · Token2022Extension[] (repeated)

Optional. Token-2022 extensions to enable at initialization. Extensions cannot be added after mint creation. Currently supported: metadata extension. Transfer hooks, transfer fees, and other extensions are coming soon.

Show Token2022Extension fields

metadata · Token2022ExtensionMetadata (object)

Embed token metadata directly in the mint account.

Show Token2022ExtensionMetadata fields

name · string

Token name (e.g. “My Token”).

symbol · string

Token symbol (e.g. “MTK”).

uri · string

URI pointing to off-chain metadata JSON.

additional_metadata · key-value pairs (repeated)

Additional custom metadata fields as key-value pairs.

Response

instructions · SolanaInstruction[] (repeated) · required

Ordered instructions. Submit in this exact order: System::CreateAccount → extension pre-init → initialize_mint → extension post-init.

lamports · uint64

Lamports deposited for rent exemption. Covers base mint size plus variable extension data.

space · uint64

Initial bytes allocated by System::CreateAccount. Token-2022 may realloc beyond this for variable-length extension data.

Code Examples

Go

resp, err := client.CreateToken2022Mint(ctx, &token_v1.CreateToken2022MintRequest{
    PayerPubKey:          "YourPayerAddress...",
    MintPubKey:           "YourNewMintAddress...",
    MintAuthorityPubKey:  "YourMintAuthorityAddress...",
    Decimals:             6,
    // Extensions: []*token_v1.Token2022Extension{...}, // optional
})
if err != nil {
    log.Fatal(err)
}
// Add all instructions to your transaction in order
for _, instr := range resp.Instructions {
    tx.AddInstruction(instr)
}

CreateSPLTokenMint

Creates and fully initializes a legacy SPL Token mint. Returns System::CreateAccount + initialize_mint + optional Metaplex CreateMetadataAccountV3. Space is always 82 bytes for SPL Token mints.

Request

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

Pays for account creation. Must be a signer.

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

The mint account to create. Must be a signer (new keypair).

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

The authority that can mint new tokens.

freeze_authority_pub_key · Base58-encoded public key (string)

Optional. Authority that can freeze token accounts. Omit to disable freeze.

decimals · uint32 · required

Decimal precision. Common values: 9 (SOL-like), 6 (USDC-like), 0 (NFTs).

metadata · MetaplexTokenMetadata (object)

Optional. Metaplex on-chain metadata. When provided, appends a CreateMetadataAccountV3 instruction.

Show MetaplexTokenMetadata fields

name · string

Token name (e.g. “My Token”).

symbol · string

Token symbol (e.g. “MTK”).

uri · string

URL pointing to the off-chain metadata JSON (e.g. Arweave or IPFS link).

Response

instructions · SolanaInstruction[] (repeated) · required

Ordered: System::CreateAccount, initialize_mint, and optionally CreateMetadataAccountV3.

lamports · uint64

Rent exemption lamports for the mint account.

space · uint64

Always 82 for SPL Token mints.

Code Examples
