# Usage


## Get Accounts



1. Open `4.transfer-nftokens.html` in a browser.
2. Get test accounts.
    1. If you have existing NFT-Devnet account seeds
        1. Paste account seeds in the **Seeds** field.
        2. Click **Get Accounts from Seeds**.
    2. If you do not have NFT-Devnet account seeds:
        3. Visit the [XRP Testnet Faucet](https://xrpl.org/xrp-testnet-faucet.html) page.
        4. Click **Generate NFT-Devnet credentials**.
        5. Copy the account **Secret**.
        6. Paste the secret in a persistent location, such as a notepad, and press return.
        7. Click **Generate NFT-Devnet credentials** to create a second account.
        8. Copy the account **Secret**.

## Create a Sell Offer

To create a NFToken sell offer:



1. Enter the **Amount** of the sell offer in drops (millionths of an XRP).
2. Set the **Flags** field to _1_.
3. Enter the **Token ID** of the NFToken you want to sell.
4. Click **Create Sell Offer**.

The important piece of information in the response is the Token Offer Index, labeled as _Index,_ which is used to accept the sell offer.



![NFToken Sell Offer](img/quickstart15.png)



## Accept Sell Offer

Once a sell offer is available, another account can opt to accept the offer and purchase the NFToken.

To accept an available sell offer:



1. Enter the **Token Offer Index** (labeled as _Index_ in the token offer results. This is not the same as the Token ID).
2. Click **Accept Sell Offer**.



![Accept Sell Offer](img/quickstart16.png)



## Create a Buy Offer

You can offer to buy a NFToken from another account.

To create an offer to buy a NFToken:



1. Enter the **Amount** of your offer.
2. Enter the **Token ID**.
3. Enter the owner’s account string in the **Owner** field.
4. Click **Create Buy Offer**.



![NFToken Buy Offer](img/quickstart17.png)



## Accept a Buy Offer

To accept an offer to buy a NFToken:



1. Enter the **Token Offer ID** (the **Index** of the token offer).
2. Enter the buyer’s account string in the **Owner** field (the buyer is the owner of the token offer).
3. Click **Accept Buy Offer**.



![Accept Buy Offer](img/quickstart18.png)

## Create Sell Offer


```
// *******************************************************
// ****************** Create Sell Offer ******************
// *******************************************************
```


Connect to the ledger and get the wallet accounts.


```
      async function createSellOffer() {
        const standby_wallet = xrpl.Wallet.fromSeed(standbySeedField.value)
        const operational_wallet = xrpl.Wallet.fromSeed(operationalSeedField.value)
          let net = getNet()
          const client = new xrpl.Client(net)
          results = 'Connecting to ' + getNet() + '...'
          document.getElementById('standbyResultField').value = results
        await client.connect()
          results += '\nConnected. Creating sell offer...'
          document.getElementById('standbyResultField').value = results


```


Define the transaction. The _Flags_ value of 1 indicates that this transaction is a sell offer.


```
        const transactionBlob = {
              "TransactionType": "NFTokenCreateOffer",
              "Account": standby_wallet.classicAddress,
              "TokenID": standbyTokenIdField.value,
              "Amount": standbyAmountField.value,
              "Flags": parseInt(standbyFlagsField.value)
        }


```


Submit the transaction and wait for the results.

        


```
        const tx = await client.submitAndWait(transactionBlob,{wallet: standby_wallet})
```


      


```
        results += '\n\n***Sell Offers***\n'
```


Request the list of sell offers for the token.


```


        let nftSellOffers
          try {
            nftSellOffers = await client.request({
              method: "nft_sell_offers",
              tokenid: standbyTokenIdField.value  
          })
          } catch (err) {
            nftSellOffers = "No sell offers."
        }
        results += JSON.stringify(nftSellOffers,null,2)
        results += '\n\n***Buy Offers***\n'
```


Request the list of buy offers for the token.


```
        let nftBuyOffers
        try {

// *******************************************************
// ******************** Cancel Offer *********************
// *******************************************************

      async function cancelOffer() {    
```


Get the standby wallet and connect to the ledger.


```
        const wallet = xrpl.Wallet.fromSeed(standbySeedField.value)

          method: "nft_sell_offers",
          tokenid: standbyTokenIdField.value
          })
          } catch (err) {
            nftSellOffers = "No sell offers."
        }
        results += JSON.stringify(nftSellOffers,null,2)
```


Request the list of buy offers for the token.


```
        results += "\n\n***Buy Offers***\n"
        let nftBuyOffers
        try {
          nftBuyOffers = await client.request({
        method: "nft_buy_offers",
        tokenid: standbyTokenIdField.value })
        } catch (err) {

        }
        results += JSON.stringify(nftBuyOffers,null,2)
```


Report the transaction results.


```


        results += "\nTransaction result:\n" +
