@stellar-expert/tx-meta-effects-parser v6.4.0

@stellar-expert/tx-meta-effects-parser

Low-level effects parser for Stellar transaction results and meta XDR

Some Stellar operations yield non-deterministic results, so developers often have to pull the data from Horizon /effects API endpoints. This package provides the ability to retrieve atomic ledger state modifications directly from the transaction execution result and metadata.

Installation

npm i @stellar-expert/tx-meta-effects-parser

Usage

const {parseTxOperationsMeta} = require('@stellar-expert/tx-meta-effects-parser')

const res = parseTxOperationsMeta({
    network: 'Public Global Stellar Network ; September 2015',
    tx: '_base64-encoded_transaction_envelope_XDR_', // trasnaction envelope XDR
    result: '_base64-encoded_transaction_result_XDR_', // trasnaction result XDR
    meta: '_base64-encoded_transaction_result_meta_XDR_', // trasnaction meta XDR
    processSystemEvents: false, // whether to analyze system Soroban diagnostic events
    mapSac: false, // whether to map Classic assets to Soroban contracts automatically
    processFailedOpEffects: false, // whether to analyze effects in failed transactions
    protocol: 21 // different versions of Stelalr protocol may yield uninform effects  
})

console.log(res.effects)
console.log(res.operations[0].effects)

Example:

parseTxOperationsMeta({
    network: 'Public Global Stellar Network ; September 2015',
