Transferring Tokens

You will need to transfer tokens for:

• Implementing various gameplay features such as gifting, trading, and rewards.
• Supporting secure and efficient token transactions.
• Providing a seamless user experience by allowing token transfers without leaving the game environment.

What you'll need:

• Some Enjin Coin on Enjin Matrixchain to pay for Transaction Fees and a deposit of 0.01 ENJ is required for the Token Account Deposit, for each new token holder.
  You can obtain cENJ (Canary ENJ) for testing from the Canary faucet.
• An Enjin Platform Account.
• A Collection and a Token to mint.

There are two ways to transfer a token:

1. Using the Enjin Dashboard
2. Using the GraphQL API & SDKs

Option A. Using the Enjin Dashboard

In the Platform menu, navigate to "Tokens".
Locate the token you wish to transfer, click the 3 vertical dots (⋮) to it's right, then click the "Transfer" button.

Need to perform multiple transfers?

Click on the "Batch" button, followed by "Batch Transfer".

Fill in the recipient, amount, and other optional arguments in the corresponding fields.
Once you're satisfied with the options, click on the "Transfer" button at the bottom right corner to create the request.

Clicking "View" on the notification will take you to your Transactions List.

Since this request requires a Transaction

, it'll need to be signed with your Wallet.

• If a Wallet Daemon is running and configured, the transaction request will be signed automatically.
• If a wallet is connected such as the Enjin Wallet or Polkadot.js, the transaction must be signed manually by clicking the "Sign" button and approving the signature request in your wallet.

If you're looking to distribute tokens to your community or players, but don't have their account addresses, don't worry! Our solution is Enjin Beam.
Proceed to the Distributing Tokens via QR tutorial to learn more.

Option B. Using the Enjin API & SDKs

Transferring an asset

SimpleTransferToken mutation simplifies the process of transferring a specific token from one wallet to another. It is a straightforward way to facilitate token transfers without the need for complex intermediary steps.

GraphQL

mutation TransferToken{
  SimpleTransferToken(
    collectionId: 36105 #Specify the collection ID
    recipient: "cxLU94nRz1en6gHnXnYPyTdtcZZ9dqBasexvexjArj4V1Qr8f" #Specify the recipent address
    params: {
      tokenId: {integer: 0} #Specify the token ID
      amount: 1 #Choose the transfer amount
    }
  ){
    id
    method
    state
  }
}

Transferring ENJ token

To send ENJ / CENJ tokens from one wallet to another, use the TransferAllowDeath mutation, or the TransferKeepAlive if you want to make sure the account doesn't get reaped (Read more about account reaping):

GraphQL

mutation TransferENJTokens {
  TransferKeepAlive(
    recipient: "cxLU94nRz1en6gHnXnYPyTdtcZZ9dqBasexvexjArj4V1Qr8f" #Specify the recipent address
    amount: 5000000000000000000 #Specify the amount of tokens to transfer

    state

Notes:

• amount argument
  • In the TransferBalance mutation, the amount argument is denoted in u128. This means that the number you specify is divided by 10^18 to determine the actual amount of ENJ to be transferred.
    In the example above, an amount of 5000000000000000000 will actually send 5 ENJ. Keep this in mind when specifying the amount in your mutations.
• keepAlive argument
  • Set to true if you want to make sure the account doesn't get reaped.
    Learn more about keepAlive argument here

Batch Transferring ENJ token

To send ENJ / CENJ tokens from one wallet to multiple addresses or in multiple transactions, we use the BatchTransferBalance mutation

        account: "cxLU94nRz1en6gHnXnYPyTdtcZZ9dqBasexvexjArj4V1Qr8f", #Specify the recipent address
