Mint Sui Tokens

The 20lab mint Sui token tool lets you create additional supply of an existing Sui coin and send the newly minted tokens to any wallet address. It's the standard way to handle scheduled emissions, expand circulating supply, or fund new initiatives after initial deployment.

The tool requires the connected wallet to hold the token's treasury cap. It works with any coin built on the standard Move Coin module and verifies cap ownership on-chain before allowing any minting transaction. End-to-end walkthrough: how to mint Sui tokens.

To mint more Sui tokens with 20lab:

1. Connect the wallet that holds the treasury cap
2. Enter your token's coin type or address
3. Enter the amount of tokens to mint
4. Specify the destination wallet address
5. Confirm the transaction

The new tokens appear in the destination wallet immediately as a Coin object. The recipient doesn't need to set up any special account beforehand - Sui's object-centric model means new coins can be sent directly without account creation transactions. To set up your token with mint capability from the start, see our mintable Sui token guide.

Only the current treasury cap holder can create additional Sui token supply. This is typically:

• The wallet that originally deployed the token
• Any wallet the treasury cap has been transferred to
• A multisig wallet if treasury cap was delegated
• A Move smart contract that owns the treasury cap for automated emissions

If the treasury cap has been revoked, no one can mint additional tokens - the supply is permanently capped at the amount that existed when the revocation happened. This is how Sui projects guarantee fixed supply.

The technical maximum for any Sui coin is 2⁶⁴-1 units (about 18.4 quintillion).

In practice, the real limits are:

• Your published tokenomics - Minting beyond announced caps destroys community trust instantly and is visible on-chain
• Your project's emission schedule - Predictable inflation is fine; surprise mints are not

The 20lab tool will mint any amount within technical limits, but responsible projects stick to their published supply commitments.

The mint tool creates tokens to one wallet at a time, but you can achieve the same outcome efficiently in two steps:

1. Mint the total required amount to your own wallet
2. Use the 20lab Sui multisender to distribute to multiple recipients in batches

This two-step approach is more flexible than direct multi-mint because the multisender accepts CSV uploads, supports equal or per-address amounts, and works for any Sui coin regardless of treasury cap status. It's the standard pattern for airdrops following a mint event.

Minting more Sui tokens doesn't directly change existing holders' balances, but it has real economic effects:

• Dilution - Each existing token represents a smaller fraction of the total supply
• Market price - Increased supply can push price down if not matched by demand
• Voting power - For governance tokens, relative voting weight shifts
• Liquidity pool ratios - Unaffected directly, but the price impact flows through to Cetus, Bluefin, and other Sui DEX pools

Transparent communication about minting schedules is essential. Many successful projects publish emission schedules in advance and announce every mint with the transaction digest for verification.

Yes - every Sui token mint is permanently recorded and visible:

• Sui Explorer and Suiscan show every mint transaction in the coin's history
• The token's total supply updates in real time on-chain
• Mint transactions appear in the treasury cap holder's wallet history
• DexScreener, Birdeye, and other analytics platforms track supply changes

This means any deviation from a published emission schedule is immediately visible to your entire community. There's no way to hide a mint on Sui.

The 20lab interface checks the on-chain treasury cap before allowing any minting attempt:

• If your connected wallet doesn't hold the treasury cap, the mint button is disabled
• You never waste SUI on a transaction that would fail

If the treasury cap has been revoked, no minting is possible regardless of which wallet you connect.
