TRC-10

TRC-10 is a token standard in TRON Ecosystem, which is based on chain rather than TVM. By paying 1024 TRX, every account in TRON network is allowed to issue TRC-10 token.

Issue

By utilizingAssetIssueContract, a particular type of transaction in TRON, each account is able to issue TRC-10 after paying 1024 TRX.

• HTTP API
  Trough FullNode wallet/createassetissue to create an unsigned transaction issuing TRC-10,

  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}
  }'
  

  Once the transaction is done, we need to sign and broadcast this transaction in order to implement the issuing. Details can be found in Transactions.

• TronWeb SDK

  javascript=

  const privateKey = "...";
  var createAssetAddress = "TM2TmqauSEiRf16CyFgzHV2BVxBejY9iyR";
  const trc_options = {
        name : "test", 
        abbreviation : "tt",

  //create an unsigned transaction for TRC-10 issuing
  tradeobj = await tronWeb.transactionBuilder.createAsset(
        trc_options,
        createAssetAddress
  ).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;
  });
  

Transfer

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

• HTTP API
  With fullnode HTTP API wallet/transferasset to start an unsigned transaction,

  javascript=

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

  When the transaction is created, we need to sign and broadcast this transaction in order to implement the transfer. Details can be found in 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 fullnode HTTP APIwallet/getaccount shows the TRC-10 balance in 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');});
