/v3/nft/mint/add

2 credits per API call

Allow a blockchain address (the minter parameter in the request body) to mint NFTs on your NFT smart contract (the contractAddress parameter in the request body).

NOTE: Use this API only when you are using NFT Express with your own smart contract. For more information, see "Use your own smart contract to mint NFTs" in Mint an NFT.
Do not use this API in any other case.

This API is supported for the following blockchains:

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

Signing a transaction
When allowing a blockchain address to mint NFTs, 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) and provide the signature ID instead of the private key in the API. Alternatively, you can use the Tatum JavaScript client.
