fikatron

Use GRPC to communicate with the TRON node to implement balance queries and other related operations.

Basic Usage

Installation

To get the package, execute:

go get github.com/gofika/fikatron

Example

package main

import (
	"encoding/hex"
	"fmt"

	"github.com/btcsuite/btcd/btcec/v2"
	"github.com/gofika/fikatron"
	"google.golang.org/grpc"
	"google.golang.org/grpc/credentials/insecure"
)

func main() {
	const target = "grpc.trongrid.io:50051"
	client, err := fikatron.NewClient(target, grpc.WithTransportCredentials(insecure.NewCredentials()))
	if err != nil {
		panic(err)
	}

	// calculate address
	privateKeyHex := "a3f4af5e7b28eb215f3887baa4f0e5b8d7e7c8d6e5f4c3b2a190807060504030"
	privateKeyBytes, err := hex.DecodeString(privateKeyHex)
	if err != nil {
		panic(err)
	}
	_, publicKey := btcec.PrivKeyFromBytes(privateKeyBytes)
	address := fikatron.AddressFromPublicKey(publicKey.ToECDSA())

	// get account
	account, err := client.Account(address)
	if err != nil {
		panic(err)
	}
	fmt.Printf("address: %s, balance: %d\n", address, account.Balance)

	// get TRC20-USDT balance
	const usdtContractAddress = "TR7NHqjeKQxGTCi8q8ZY4pL8otSzgjLj6t"
	balance, err := client.TRC20Balance(usdtContractAddress, usdtContractAddress)
	if err != nil {
		panic(err)
	}
	fmt.Printf("address: %s, TRC20-USDT balance: %s\n", usdtContractAddress, balance.String())
}
