Frequently asked questions
A token on Solana using the SPL standard — similar in role to ERC-20 on Ethereum.
What does Revoke Mint Authority mean?
It removes the ability to mint new tokens after deploy. Supply becomes fixed and cannot be increased.
What does Revoke Freeze Authority mean?
No one (including you) can freeze holders’ token accounts — a common choice for maximum openness.
How much does it cost to create a token on Solana?
MintLab’s estimate includes deploy plus permanent storage for your logo and generated metadata. Expect on the order of ~0.024 SOL total on mainnet before optional revoke fees; Devnet is free with test SOL from a faucet.
How do metadata work on MintLab?
MintLab handles everything automatically. Upload your logo and, if you like, a short token description. The system builds the metadata and saves it on Arweave permanently. No technical setup on your side.
Do I have to host metadata myself?
No. MintLab includes permanent Arweave storage in the fee (about 0.010 SOL on top of deploy). Your logo and metadata stay online without subscriptions.
Can I use IPFS instead of Arweave?
MintLab currently uses Arweave for permanent persistence. IPFS is not supported because it typically requires manual pinning and ongoing upkeep.
How much does storage cost?
About 0.010 SOL extra on top of the token deploy (total around 0.024 SOL before optional revoke lines). It is a one-time charge — no recurring hosting bill from MintLab for that storage.
Can I skip the logo or description?
On the MintLab form, Token Logo is required so wallets and explorers can show your brand. Token Description is optional. If you use other tools outside MintLab, different rules may apply.
What’s the difference between Devnet and Mainnet?
Devnet is a test network with free SOL for experiments. Mainnet-Beta is live: tokens and fees are real.
Can I change supply or decimals after creation?
No. Supply and decimals are fixed once the mint exists. Revoking mint authority only stops new minting; it does not change the numbers you started with.
Where can I read more about logo upload and metadata?
