Token Mint

Token Mint increases the circulating supply of an SPL or Token-2022 token you already created. You point it at the mint, confirm that your connected wallet still holds the mint authority, preview the new total supply, then mint fresh units to your own wallet or any address you pick.

Network fee, rent and transaction value are separate.

When this tool fits

#when-this-tool-fits

• You hold the mint authority and have decided, on purpose, to raise the supply.
• You are funding a treasury, an airdrop pool, a liquidity allocation, or a vesting wallet from a token you already run.
• You want to add the final tranche of supply before capping the token with Revoke Mint or Make Immutable.

Before you start

#before-you-start

• A connected wallet that currently holds the token’s mint authority (how to connect), either the header wallet or a Local Signer key. If the connected wallet is not the authority, the Mint Tokens button stays disabled.
• The mint address of an existing SPL or Token-2022 token whose mint authority has not been revoked.
• Enough SOL in the signing wallet for the network fee, the platform fee, and rent if the destination needs a new token account. The button also stays disabled while the balance cannot cover the platform fee plus a small network margin.

How to use it

#how-to-use-it

1. Load mint info from chain

   Connect your wallet, paste the token’s mint address into the selector, and click Load Token. The panel shows Current Supply, Decimals, and Mint Authority, which reads Active only when your connected wallet holds it, with the authority address under it.

2. Set amount and destination

   Type how many tokens to mint in normal display units, not raw units. Leave Destination Wallet empty to mint to your own wallet, or paste another address. Check the New Total Supply preview and the platform fee in the summary.

3. Sign the mint transaction

   Click Mint Tokens and approve in your wallet. The tool waits for confirmation, re-reads the supply on chain, and shows the minted amount, the new supply, a copyable signature, and a Solscan link.

Key settings

#key-settings

• Token Mint Address: The existing SPL or Token-2022 token you want to add supply to. Click Load Token to read its supply, decimals, and mint authority before you mint. Uses the shared token selector.
• Amount To Mint: How many tokens to mint, in display units. Must be greater than zero. The tool converts it to raw units using the token’s decimals.
• Destination Wallet: Where the new tokens go. Leave it empty to mint to your connected wallet. If the destination has no token account for this mint, one is created during the transaction, and the signer pays the rent. Each mint sends to a single destination; to spread new supply across many wallets afterwards, use Multi Sender.

Fees and costs

#fees-and-costs

Caution

About fees. Every action has two costs: the Solana network fee paid to validators, and the J Tools platform fee. The platform fee always shows in the app before you confirm, and nothing is charged until you sign. Fees can change over time, so trust the in-app summary rather than a number you saw once.

Cost	Amount
J Tools platform fee	0.1 SOL
Solana network fee	Paid to validators during the transaction; shown in the live summary.
Rent and transaction value	Shown separately when required; not part of the platform fee.

How it works

#how-it-works

• The tool checks which token program owns the mint, classic SPL Token or Token-2022, and reads the mint account through that program. It shows the current supply, the decimals, and the mint authority: Active when your connected wallet holds it, Inactive when another wallet holds it or it was revoked. This read is live, not cached from a list.
• You enter an amount in display units. The tool multiplies by the token’s decimals to get the raw integer amount the program actually mints. A token with 6 decimals turns “10” into 10,000,000 base units.
• If the destination does not yet have an associated token account for this mint, the transaction includes a create-account instruction first, and the signing wallet pays the small rent deposit for it. The account is derived for the same token program as the mint.
• The mint-to instruction runs. It requires the mint authority to sign, which is why your connected wallet must be that authority. The token program rejects the instruction if any other key tries to sign it.
• The platform fee is attached to the same transaction as a separate transfer, so the fee and the mint either both succeed or both fail. The live fee amount is shown in the summary before you sign.

FAQ

#faq

Does Token Mint work on Token-2022 tokens? Yes.

Yes. The tool checks which program owns the mint and sends every read and the mint instruction to that program, so a Token-2022 mint loads and mints the same way a classic SPL mint does. The rule does not change: your connected wallet must hold the mint authority. The difference between the two programs is covered in SPL vs Token-2022.

Can I undo a mint? No.

No. Once tokens are minted they exist on chain for good. There is no reversal. The closest action is Token Burner, which destroys units held in your own account and lowers total supply. It is a separate transaction and only works on tokens you hold.

Before you sign

#before-you-sign

Check the live summary before signing. The app is the current source of truth for amount, fee and route.

Common issues

#common-issues

• Connected wallet is not the mint authority. Only the wallet that holds the mint authority can mint. Connect that wallet, then load the token again.
• Mint authority already revoked. If the authority is set to None, the token is capped and no further minting is possible. Mint Authority reads Inactive with no address under it, and the button stays disabled.
• Amount entered in raw units. Type the amount in display units. Entering raw base units mints far more than you intended because the tool also applies the decimals.

Practical tips

#practical-tips

• Mint, then revoke. If you know the final supply, mint the last tranche and immediately revoke the mint authority with Revoke Mint so the cap is provable on chain.
• Later mints to the same wallet cost less. The first mint to a wallet creates its token account and pays the rent; later mints to that wallet skip the account creation and the rent.

Note

About wallet warnings. Some tools bundle several instructions into one transaction, for example creating a token and its metadata together. Phantom can show a caution banner for these transactions, and where the tool tells you to expect one, it does not mean something is wrong. Read what you are signing, then approve if it matches what you set up. If a warning appears that the tool did not mention, decline it and tell support.

Tip

J Tools is non-custodial. We never store your wallet’s private keys and never ask for your seed phrase. Every transaction you approve in a connected wallet is signed inside that wallet, and its key never reaches our servers. A few multi-wallet tools do let you paste private keys for throwaway hot wallets, which stay in your browser tab and sign there. Holder Booster is the one tool that hands a key to our worker: the fresh distributor wallet it creates for each run, sent encrypted. Never paste a key tied to long-term holdings, and if a page ever asks for your seed phrase, stop and close it.
