Mint Tokens

The mintTokens function mints tokens from a token mint to a destination account. The mint authority must sign the transaction.

Usage

const signature = await connection.mintTokens(
  mintAddress, // address of the token mint
  mintAuthority, // signer with authority to mint tokens
  amount, // amount of tokens to mint
  destination, // address to receive the tokens
);

Parameters

• mintAddress: Address - Address of the token mint
• mintAuthority: KeyPairSigner - Signer with authority to mint tokens
• amount: bigint - Amount of tokens to mint (in base units)
• destination: Address - Address to receive the minted tokens

Returns

Returns a Promise<Signature> - The transaction signature that can be used to look up the transaction.

Example

// Create a new token mint
const mintAuthority = await connection.createWallet({
  airdropAmount: lamports(1n * SOL),
});
 
const mintAddress = await connection.createTokenMint(
  mintAuthority,
  9, // decimals
  "My Token",
  "TKN",
  "https://example.com/token.json",
);
 
// Mint 100 tokens to the mint authority's account
const signature = await connection.mintTokens(
  mintAddress, 
  mintAuthority, 
  100n, 
  mintAuthority.address
);

Error Handling

The function will throw an error if:

• The mint authority is not the actual authority for the token mint
• The destination account doesn’t exist
• The mint authority lacks sufficient SOL to pay for the transaction
• The RPC connection fails
