NFT | Creation & Management

Financial Application 2 (FA2) token standard

Create and mint NFTs via the FA2 (Financial Application 2) unified token standard on Tezos, offering the following token types:

fungible (equals ERC-20 on Ethereum)
non-fungible (equals ERC-721 on Ethereum)
non-transferable (equals ERC-1238 on Ethereum)
multi-asset contracts (equals ERC-1155 on Ethereum)

FA2 implementations

The FA2 standard has multiple implementations. We support the following:

Single

With this implementation, you can only have one collection. It is like the ERC-721 style. Only owner minter can mint new NFTs.

Multiple

With this implementation, you can have multiple collections. In each collection, you can define the number of copies of each NFT. It is somehow like the ERC-1155 style.

Smart contract deployment

We offer a set of default FA2 based smart contract templates, providing the main functionality needed for NFT projects.

Curl call example

curl -X POST "http://0.0.0.0:7000/v2/nftkit/nft/tezos/chain/{{chain}}/contract/deploy" 
-H  "Content-Type: application/json" 
-d "{"owner":"string","type":"string"}"

Path parameters:

chain: [string] chain to work with. Either TEZOS or GHOSTNET.

Body parameters

{
  "owner": "tz1YiZtFfeu6qmr2G6PnyisJNjxDyaEWXs9J",
  "type": "SINGLE"
}

owner: [string] the owner(Admin) of the smart contract.
type: [string] the FA2 smart contract implementation. Either SINGLE or MULTIPLE. For more explanation, you can click here.

Example:

curl -X POST "http://0.0.0.0:7000/v2/nftkit/nft/tezos/chain/GHOSTNET/contract/deploy" 
-H  "Content-Type: application/json" 
-d "{"owner":"tz1YiZtFfeu6qmr2G6PnyisJNjxDyaEWXs9J","type":"SINGLE"}"

val chain= TezosChain.GHOSTNET
val smartContractOwner= "tz1YiZtFfeu6qmr2G6PnyisJNjxDyaEWXs9J"
val smartContractType= Fa2SmartContractType.SINGLE
val result = TezosNftService.deploySmartContract(chain, smartContractOwner, smartContractType)
println("Smart contract address: ${result.contractAddress}"
println("Smart contract external url: ${result.contractExternalUrl}")

Add minter

The FA2 smart contract implementation allows minting NFTs from different accounts. The owner of the smart contract is allowed to add new minters.

NFT Minting

With this API, you can mint a new NFT. It have multiple options to manages NFT minting. You can generate NFT URI metadata by yourself or let the NFT KIT generate it.
