# What happens when you mint an NFT? Minting creates a token within a particular NFT contract. The contract determines who can mint, what it costs and who receives the token; ERC-721 does not prescribe one universal public mint function. A successful mint should be checked through the resulting ownership or balance and relevant events, not just a website’s celebration screen.

([ERC-721 NFT standard](https://eips.ethereum.org/EIPS/eip-721); [ERC-1155 multi-token standard](https://eips.ethereum.org/EIPS/eip-1155)) - **Contract rules:** Mint interfaces and eligibility are implementation-specific. ([ERC-721 NFT standard](https://eips.ethereum.org/EIPS/eip-721)) - **Fees:** A paid mint can require both its purchase value and transaction gas. ([Ethereum gas and fees](https://ethereum.org/en/developers/docs/gas/)) ## The collection defines the sale mechanics An NFT standard describes ownership, transfers and events, but does not standardize every sale process. A mint might be restricted, priced or assigned to a recipient according to the collection’s code. The same button label can invoke different contract behavior. Verify the intended contract and network before approving. A copied collection title or image is not enough to identify the issuer.

The hypothetical total debit is 0.021 ETH. These are example amounts, not a current collection quote. A reverted transaction does not complete the mint but can still consume gas for work performed. Paying gas alone is not evidence that the NFT was created for your address.

For ERC-1155, also inspect the quantity for that token ID. A token ID is only meaningful within its contract and chain. A mint also does not guarantee that metadata is immutable or that its image will remain available. Token creation and media storage are distinct questions.

No. Minting is a contract operation that creates a token. It does not by itself establish authorship of an image or legal rights to it. Evidence: [ERC-721 NFT standard](https://eips.ethereum.org/EIPS/eip-721) ### Can two collections both mint token number 1? Yes. Token identifiers are interpreted within their respective contracts. Identify the network and contract along with the token ID.
