# Minting

The buyer creates a representation in JSON format of the entire trade. We are still defining the JSON structure but it will be something like this:

```javascript
let tradeInfo = {
  counterPart: '0xSomeCountearpart',
  description: 'Show me the money',
  payments: [
    {
      amount: 100,
      collateral: 10,
      type: 'stream',
      startDate: '2022-12-12',
      endDate: '2023-12-12'
    }
  ]
}
```

### Approval

When minting an asset, the seller pays a fee to the DAO. This fee is dependent on the tokens the asset is linked to. If an asset deals in two tokens, then a fee is paid for each token.

Prior to minting the asset, the seller must approve a transfer for each token.

```javascript
await seller.invoke(
    txFlowContract, 
    'approve', 
    { spender: txAssetContract.address, amount: toUint256WithFelts("5") }, 
    { maxFee: FEE}
)
```

### Initiate

As previously stated, initiating the asset means we are minting an NFT. This minting happens by calling a custom function as per the code below:

```javascript
const txHash = await seller.invoke(
    txAssetContract, 
    "init", 
    { 
      counterpart: buyer.starknetContract.address, 
      agreementTerms: strToFeltArr(JSON.stringify(tradeInfo)),
      tokens: [txFlowContract.address],
      members: [member1.starknetContract.address, member2.starknetContract.address],
      weights: [2, 1]
    },
    { maxFee: FEE}
  )

let txReceipt = await starknet.getTransactionReceipt(txHash)
let tokenId = fromUint256WithFelts({ low: BigInt(txReceipt['events'][0]['data'][0]), high: BigInt(txReceipt['events'][0]['data'][1]) })
```

Minting the asset results in a **tokenId** which is used to identify the asset in the platform.

### Members

Assets can have beneficial members different to the owner of the asset. These members are able to withdraw tokens that are in the balance of the Asset / NFT. The percentage of the tokens that the members are able to withdraw are defined by the weights. In the case above, member 1 is able to withdraw 2 / 3 the total tokens while member 2 can withdraw 1 / 3.
