On-chain Transaction Parser

A powerful library for parsing on-chain transactions into clear, human-readable actions, streamlining blockchain data analysis and interpretation.

Usage

package main

import (
	"encoding/json"
	"fmt"
	"github.com/0xjeffro/tx-parser/solana"
	"github.com/0xjeffro/tx-parser/solana/types"
	"io/ioutil"
	"net/http"
	"strings"
)

type RpcRsp struct {
	JsonRpc string      `json:"jsonrpc"`
	Result  types.RawTx `json:"result"`
	Id      int         `json:"id"`
}

func main() { 
	// Fetch a raw transaction from the Solana RPC 
	url := "https://api.mainnet-beta.solana.com/"
	method := "POST"
	tx := "5tuQKcRyFFNQw8XmD2Rg7ZuvXHxJynf9Z3oWFGewU9i5MREpQFhko1d5e6i3z15DqngcRGsXNBtpDvqc5EToAaRd"

	payload := strings.NewReader(fmt.Sprintf(`{
		"jsonrpc": "2.0",
		"id": 1,
		"method": "getTransaction",
		"params": [
		  "%s",
		  {
			"encoding": "json",
			"maxSupportedTransactionVersion": 0
		  }
		]
	}`, tx))

	client := &http.Client{}
	req, err := http.NewRequest(method, url, payload)

	if err != nil {
		fmt.Println(err)
		return
	}
	req.Header.Add("Content-Type", "application/json")

	res, err := client.Do(req)
	if err != nil {
		fmt.Println(err)
		return
	}
	defer res.Body.Close()

	body, err := ioutil.ReadAll(res.Body)
	if err != nil {
		fmt.Println(err)
		return
	}
	// Parse the raw transaction
	var result RpcRsp
	err = json.Unmarshal(body, &result)
	if err != nil {
		fmt.Println(err)
		return
	}

	var txs []types.RawTx
	txs = append(txs, result.Result)
	b, err := json.Marshal(txs)
	if err != nil {
		return
	}
	parsed, err := solana.Parser(b)
	if err != nil {
		return
	}
	parsedJson, err := json.Marshal(parsed)
	if err != nil {
		return
	}
	fmt.Println(string(parsedJson))
}
