# Mint an NFT (1155)

ERC-1155 is a token standard that allows for both fungible and non-fungible tokens to be created within the same contract. This means it can be used to represent unique NFTs (like ERC-721) as well as semi-fungible tokens or multiple copies of the same NFT.

### **Network**

Select the blockchain network on which the NFT will be minted. In the example, Ethereum Mainnet is selected.

### **Contract address**

Enter the contract address of the NFT collection or project. - конкретний контракт&#x20;

### **Has server signature support (optional)**

Enable this toggle if your NFT minting process requires server-side signature support. This is an advanced security feature that protects your NFT mint from unauthorized minting by external users.

To utilize this feature, you will need a special contract template. Request this template from the сlaimr support team.

#### **Why server-side signature is important?**

All data and events on the blockchain are publicly accessible. This means that anyone with technical knowledge can potentially exploit the NFT minting process. They could bypass your campaign's tasks and mint NFTs directly to their own wallets.

claimr's server-side signature adds a layer of protection. It utilizes a secure server-side wallet to sign a special message that is verified within the NFT contract. This ensures that only authorized mints initiated through your claimr campaign can be successful.

### **Token ID**

Specify the ID of the token within the ERC-1155 contract that you want users to mint.

### **Amount**

Specify the number of tokens with the specified ID that users need to mint to complete the task.

### **Mint fee (optional)**

If there's a fee associated with minting the NFT, specify the amount here.
