# Deploy an NFT smart contract

`POST /v3/nft/deploy`

## Request

- Base URL: `https://api.tatum.io`
- URL: `https://api.tatum.io/v3/nft/deploy`
- Auth: API key in header `x-api-key`

/v3/nft/deploy

**2 credits per API call**

Deploy an NFT smart contract on the blockchain. In a deployed NFT smart contract, you can mint NFTs (one NFT at a time or multiple NFTs at once), burn, and transfer NFTs.

Smart contracts are standardized and audited. You can review the code of a deployed NFT smart contract [here](https://github.com/tatumio/smart-contracts/tree/master/contracts/tatum).

This API is supported for the following blockchains:

*   BNB Smart Chain
*   Celo
*   Ethereum
*   Harmony
*   Klaytn
*   KuCoin Community Chain
*   Polygon
*   TRON
*   Tezos
*   Flare
*   Cronos
*   Base
*   Avalanche
*   Fantom
*   Optimism

**General NFT smart contracts**  
By default, an NFT smart contract is deployed as a **general NFT smart contract compatible with OpenSea royalties**. This is a standard NFT contract with `AccessControl` and `Ownable`, enhanced with NFT batch minting. NFTs minted on this smart contract are compatible with OpenSea and its royalty structure.

You can enable **public minting** for smart contracts. By default, public minting is disabled, which means that only the blockchain address whose private key was used to create the smart contract or the blockchain addresses [added to the smart contract as NFT minters](#operation/NftAddMinter) will be able to mint NFTs for the contract. To enable public minting and allow anyone to mint NFTs on top of the smart contract, deploy the contract with the `publicMint` parameter set to `true` in the request body.

**NFT smart contracts and NFT Express**  
If you want to use NFT Express to mint NFTs on the deployed smart contract, deploy the smart contract as a general NFT smart contract.  
After you have deployed the NFT smart contract, [add the Tatum minter address as an NFT minter to your smart contract](#operation/NftAddMinter).

For the complete information about using NFT Express on your smart contract, see "Use your own smart contract to mint NFTs" in [Mint an NFT](#operation/NftMintErc721).

**Signing a transaction**  
When deploying an NFT smart contract, you are charged a fee for the transaction, and you must sign the transaction with the private key of the blockchain address from which the fee will be deducted.

Providing the private key in the API is not a secure way of signing transactions, because the private key can be stolen or exposed. Your private keys should never leave your security perimeter. You should use the private keys only for testing a solution you are building on the **testnet** of a blockchain.

For signing transactions on the **mainnet**, we strongly recommend that you use the Tatum [Key Management System (KMS)](https://github.com/tatumio/tatum-kms) and provide the signature ID instead of the private key in the API. Alternatively, you can use the [Tatum JavaScript client](https://github.com/tatumio/tatum-js/tree/v2).

## Query parameters
