TRC-10

TRC-10 is a native token standard supported by the TRON network. Unlike TRC-20 tokens, it does not rely on the TRON Virtual Machine (TVM) but is implemented directly at the blockchain protocol level. Any account can issue a TRC-10 token — limited to one issuance per account — with a creation fee of 1024 TRX.

Issue

By utilizingAssetIssueContract, a particular type of transaction in TRON, each account is able to issue TRC-10 after paying 1,024 TRX.

• HTTP API
  The following section creates an unsigned transaction to issue TRC-10 through the FullNode HTTP API wallet/createassetissue:

  javascript=

  curl -X POST  https://api.shasta.trongrid.io/wallet/createassetissue -d '{
  "owner_address":"417946F66D0FC67924DA0AC9936183AB3B07C81126",
  "name":"0x6173736574497373756531353330383934333132313538",
  "abbr": "0x6162627231353330383934333132313538",
  "total_supply" :100000000,
  "trx_num":1,
  "num":1,
  "precision":1,
  "start_time" : 1581928489000,
  "end_time":1581938187000,
  "description":"007570646174654e616d6531353330363038383733343633",
  "url":"007570646174654e616d6531353330363038383733343633",
  "free_asset_net_limit":10000,
  "public_free_asset_net_limit":10000,
  "frozen_supply":{"frozen_amount":1, "frozen_days":2}
  }'
  

  After the transaction is created, you need to sign and broadcast this transaction in order to implement the issuing. For more details, please refer to Transactions.

Transfer

TransferAssetContract is introduced as a type of transaction in the TRON network to transfer tokens from one account address to another. It can be implemented through either the HTTP API or the TronWeb SDK.

• HTTP API
  The following section starts an unsigned transaction with the Fullnode HTTP API wallet/transferasset:

  javascript=

  curl -X POST   https://127.0.0.1:8090/wallet/transferasset -d '{
    "owner_address":"41d1e7a6bc354106cb410e65ff8b181c600ff14292", 
    "to_address": "41e552f6487585c2b58bc2c9bb4492bc1f17132cd0", 
    "asset_name": "0x6173736574497373756531353330383934333132313538", 
    "amount": 100
  }'
  

  After the transaction is created, you need to sign and broadcast this transaction in order to implement the transfer. For more details, please refer to Transactions.

• TronWeb SDK

  javascript=

  const privateKey = "..."; 
  var toAddress = "TM2TmqauSEiRf16CyFgzHV2BVxBejY9iyR";
  var tokenID= "1000088";
  var amount = 1000;
  var fromAddress = "TVDGpn4hCSzJ5nkHPLetk8KQBtwaTppnkr";
  //create an unsigned transfer
  tradeobj = await tronWeb.transactionBuilder.sendToken(
        toAddress,
        amount,
        tokenID,
        fromAddress,    
  ).then(output => {
    console.log('- Output:', output, '\n');
    return output;
  });
  //sign
  const signedtxn = await tronWeb.trx.sign(
        tradeobj,
        privateKey
  );
  //broadcast
  const receipt = await tronWeb.trx.sendRawTransaction(
        signedtxn
  ).then(output => {
    console.log('- Output:', output, '\n');
    return output;
  });
  

Check Balance

• HTTP API
  The return value of assetV2 in the Fullnode HTTP APIwallet/getaccount shows the TRC-10 token balance in the wallet:

  javascript=

   curl -X POST  https://api.shasta.trongrid.io/wallet/getaccount -d 
       '{"address": "TM2TmqauSEiRf16CyFgzHV2BVxBejY9iyR",
         "visible": true
       }'
  

• TronWeb SDK

  javascript=

  var address = "TM2TmqauSEiRf16CyFgzHV2BVxBejY9iyR"; 
  //check the balance by assetV2 value in return
  var tradeobj = await tronWeb.trx.getAccount(
        address,
  ).then(output => {console.log('- Output:', output, '\n');});
