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,

    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",

    "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

    const privateKey = "...";
    var createAssetAddress = "TM2TmqauSEiRf16CyFgzHV2BVxBejY9iyR";

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,

    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

    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,

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

    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');});
