Some services may defer minting until a sale, shifting the gas payment to the buyer; others require the creator to pay gas when creating the NFT or deploying a contract. Marketplace fees, gas, and royalties are separate costs. Of the options covered here, OpenSea’s old lazy-minting tool is no longer available for new items, while Rarible’s and Mintable’s gasless options need current eligibility and terms confirmed before you rely on them.
What “mint an NFT for free” can mean
Minting writes an NFT to a blockchain. A service may let you prepare or list an item without paying gas upfront, but defer the on-chain transaction until someone buys or transfers it. That is different from a free account, a free listing, or an NFT that never incurs gas.

Check these costs separately before choosing a marketplace:
- Gas: the blockchain transaction cost. Depending on the workflow, the creator, buyer, or a later transactor may pay it.
- Marketplace fees: charges imposed by the platform when an NFT is minted or sold.
- Royalties: creator-set amounts associated with resale. Whether and how they are enforced depends on the platform and transaction; the sources cited here do not establish enforcement terms for every option.
- Payment processing: a possible additional charge when using a payment method that supports it.
A “gasless” flow can reduce what you pay upfront, but it does not by itself prove that the whole process is free.

| OpenSea | Its current guide says new items cannot be created with its former lazy-minting tool. Its current Studio workflow requires creators to pay gas to deploy their own smart contracts and mint collections. | OpenSea lists 1% for NFT sales and 10% for minting an NFT in a primary drop. Blockchain gas is separate; sellers may also pay gas for a first listing or when accepting an offer. OpenSea Help Center, 2026 |
| Rarible | Its help material describes buyer-paid gas for a lazy-minted NFT when it sells. Current availability for every new creator or supported chain is not established. | Its FAQ, last updated September 1, 2026, lists 2% on Ethereum, Base, and Polygon, and 1.5% on Solana. Fees on other supported chains vary; gas, royalties, and payment processing may add costs. Rarible FAQ |

What to know about each marketplace
OpenSea: not a current free-mint option for new items
OpenSea’s historical Collection Manager announcement described lazy minting, where an NFT was not transferred on-chain until its first purchase or transfer, avoiding creator gas upfront. That is historical guidance, not a current route for new items. OpenSea’s creator guide says: “Effective October 3rd, 2023, users won’t be able to create new items using the lazy minting tool.” The guide says OpenSea Studio replaced that tool and that creators pay gas to deploy their own smart contracts and mint collections. See the current creator guide and the historical Collection Manager announcement.
Rank #2
OpenSea’s listed transaction charges also matter if you are comparing total costs: its Help Center lists 1% for NFT sales and 10% for minting an NFT in a primary drop. Gas goes to blockchain validators rather than OpenSea, and the platform says sellers may pay gas for a first listing or when accepting an offer. The Help Center notes that fees can change.
Rarible: potentially deferred gas, but confirm access
Rarible’s help page describes a lazy-minting flow in which the buyer pays gas when the item sells. That can mean no creator gas upfront for the described transaction, but the available guidance does not establish that every new creator can use the flow or that it is available on every chain. Confirm the option in your account and review the transaction details before relying on it.

Rarible’s FAQ lists marketplace fees of 2% on Ethereum, Base, and Polygon, and 1.5% on Solana; rates on other supported chains vary. These are platform fees, not gas rates. Rarible also identifies gas, creator royalties, and payment processing as possible additional costs. Its help material on lazy minting is available here.
Mintable: an official gasless description, with conditions to verify
Mintable’s official help page describes gasless minting on Ethereum as creation without the creator paying gas or submitting a blockchain transaction. That description does not settle who pays any deferred cost, whether the feature is currently open to new creators, which exact conditions apply, or what other fees may arise. Treat it as a possible workflow to investigate, not a guaranteed no-cost option.

How to choose without a surprise bill
- Confirm when minting happens. Find out whether the NFT is written on-chain at creation, at first sale, or at a later transfer.
- Identify who pays each gas transaction. Check whether the creator pays upfront, the buyer pays at purchase, or someone pays during a later transaction.
- Check all platform charges. Look for both primary-mint and sale fees, rather than assuming a free listing means a free transaction.
- Review royalty and payment terms. Check what royalty settings do in practice and whether the checkout method adds processing costs.
- Verify the chain and contract setup. Confirm the specific workflow supports your intended blockchain and whether you must deploy your own contract.
- Read the wallet prompt before signing. OpenSea says a crypto wallet is required. Review the transaction and displayed network cost before approving; a hardware wallet is not established as necessary by the cited guidance.
Which option is best?
If “free” means no creator gas upfront, Rarible’s described buyer-paid lazy-minting flow may fit if it is available to you and your chosen chain. Mintable documents a gasless Ethereum flow, but its current availability and conditions need confirmation. OpenSea is not a free lazy-minting choice for new items under its current guidance: its Studio process requires creator-paid gas for contract deployment and minting.
If “free” means no cost to anyone at any point, none of these sources establishes that outcome. Compare the full transaction path—including gas, marketplace charges, and any applicable royalty or payment costs—before you commit.
