/v3/nft/mint/batch

2 credits per API call

Create multiple NFT Tokens and transfer them to destination account. Create and transfer any NFT tokens from smart contract defined in contractAddress.

This API is supported for the following blockchains:

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

This operation works in two modes. First mode works just like other NFT endpoints. Every time the funds are transferred, the transaction must be signed with the corresponding private key. No one should ever send it's own private keys to the internet because there is a strong possibility of stealing keys and loss of funds. In this method, it is possible to enter privateKey or signatureId. PrivateKey should be used only for quick development on testnet versions of blockchain when there is no risk of losing funds. In production, Tatum KMS should be used for the highest security standards, and signatureId should be present in the request. Alternatively, using the Tatum client library for supported languages. Second mode enables you to mint on any custom NFT ERC-721 smart contract, on which specified minter address is approved as a minter. You don't specify private key or signatureId, only minter address, from which the NFT will be minted.
It means you perform mint multiple NFT request with following body:

{ "to": ["0x80d8bac9a6901698b3749fe336bbd1385c1f98f2"], "url": ["ipfs://QmXJJ6UF5WkF4WTJvsdhiA1etGwBLfpva7Vr9AudGMe3pj"], "tokenId": ["9876541124516"], "contractAddress":"0x3cbb48f740595ed846abb641adfcd9f04588348d", "minter": "0x542b9ac4945a3836fd12ad98acbc76a0c8b743f5", "chain": "MATIC" }

The blockchain fee of the performed transaction is paid from the address connected with built-in private key and is debited in form of credits. The credits are debited only if NFT mint requests are performed with paid API key plan. We transform fee to the credits in accordance to the rates provided by the Tatum. If you want to batch mint on ERC-721 contract which is not deployed via Tatum API, your smart contract must contain this method:

mintMultiple(address[] to, uint256[] tokenId, string[] uri): boolean

You can use addresses specified in the bellow table to be used as a minter.
