TRON SDK

The TRON SDK is a Go client library designed to simplify interaction with the TRON blockchain's API, specifically the TronGrid service. TronGrid is a public API service provided by the TRON Foundation that offers various endpoints for querying TRON blockchain data.

Features

• Retrieve information about blocks, transactions, and contract events.
• Check account balances for native tokens and TRC20 tokens.
• Obtain details about transactions and their results.
• Interact with smart contract functions and retrieve contract owner information.

Installation

To install the tron-api SDK, you can use the go get command:

go get -u github.com/distributed-lab/tron-api

Usage

package main

import (
	"fmt"
	"time"

	"github.com/distributed-lab/tron-sdk/tron_api"
)

func main() {
	apiKey := "your-api-key"
	httpApiURL := "https://api.trongrid.io"
	grpcURL := "grpc.trongrid.io:50051"

	client := tron_api.NewTronClient(httpApiURL, grpcURL, apiKey)

	blockNumber, err := client.GetNowBlock()
	if err != nil {
		fmt.Println("Error:", err)
		return
	}

	fmt.Println("Latest Block Number:", blockNumber)

	// Perform other operations using the provided methods
	// ...
}

TronGrid Usage

This SDK interacts with the TRON blockchain through the TronGrid service, which offers a range of methods to retrieve blockchain data. Some of the key methods utilized by this SDK include:

• GetNowBlock(): Retrieve the latest block number.
• GetTransactionInfoByBlockNum(block int64): Get transaction information by block number.
• GetTransactionResultById(id string): Fetch the result of a transaction by its ID.
• GetTxInfo(id string): Obtain detailed transaction information by ID.
• BalanceOf(address address.Address, tokenAddress string): Check account balances for native tokens and TRC20 tokens.
• GetContractOwner(c address.Address): Retrieve the owner of a smart contract.

For more details on these methods and other available endpoints, refer to the official TronGrid API documentation.
