Calling TRON RPC Methods

Use the exchange.IO() function to call TRON RPC methods. For methods requiring signatures, the underlying layer has automatically encapsulated the signing operations. The following lists commonly used methods. For other methods, please refer to the official TRON project documentation.

• GetAccount

  
              javascript
              
              
  exchange.IO("api", "tron", "GetAccount", "TKCG...")   // "TKCG..." is the TRON wallet address, this function returns the account information for the "TKCG..." address.
  

• GetAccountResource

  
              javascript

  function main() {
      let ret = exchange.IO("api", "tron", "TriggerConstantContract", "", "TSUUVjysXV8YqHytSNjfkNXnnB49QDvZpx", "token0()", "")  // Call the token0() method of the smart contract, TriggerConstantContract is used to call read-only methods
      let data = exchange.IO("decode", "address", Encode("raw", "raw", "hex", ret["constant_result"][0]))                        // Decode data
      return data                                                                                                                 // data: 0x891cdb91d149f23b1a45d9c5ca78a88d0cb44c18

      let data = Encode("raw", "raw", "hex", ret.constant_result[0])
      return exchange.IO("api", "tron", "ParseTRC20StringProperty", data)                                                        // Tether USD
