Internal Transactions API
Get Internal Transactions

Get Internal Transactions

Overview

The Get Internal Transactions endpoint obtains data on interactions with smart contracts by analyzing their internal transactions. At least one of the following parameters must be specified: contract, origin, sender, or sig_hash. The range should be defined by either block_number, timestamp, or block_hash. Internal transactions can be decoded and converted into a human-readable format when a smart contract's ABI is provided.

📘️

Multiple values can be set for the contract and sig_hash parameters, with a maximum of five items each.

Use Cases

Several possible combinations of parameters should be considered, where origin refers to the address of an EOA wallet, contract is a smart contract's address, and sender represents either an EOA wallet's address or a smart contract's address. To retrieve specific details about internal transactions and their function calls, follow the guidelines below.

  1. For calls of a particular function within a smart contract, specify both sig_hash and contract.

  2. For calls of a particular function within multiple smart contracts triggered by another smart contract, specify both sig_hash and sender as a contract's address.

  3. For calls of a particular function initiated by an EOA wallet, specify sig_hash and origin. Include contract to narrow your query to a specific smart contract.

  4. For calls of a particular function within a smart contract triggered by another smart contract, specify sig_hash, contract, and sender.

  5. For calls of a particular function on a smart contract triggered by another contract but initiated by an EOA wallet, specify sig_hash, contract, sender, and origin.

📘️

When using decoding, the output will include a decoded object with the function name, its parameters and values.

Usage

In this example, we receive internal transaction calls on the contract 0xdAC17F958D2ee523a2206206994597C13D831ec7, triggered by the sender address 0xc6cde7c39eb2f0f0095f41570af89efc2c1ea828, initiated by the origin address 0x36928500bc1dcd7af6a2b4008875cc336b927d57, and filtered by the signature hash of the executeTransaction function 0xa9059cbb. The block range is set from block 1 to latest.

import * as Parsiq from '@parsiq/parsiq.js';
 
const client = Parsiq.createClient(process.env.API_KEY, Parsiq.ChainId.ETH_MAINNET);
 
const internalTransactions = client.internalTransactions.getByBlockRange(
    1, 'latest',
    {
      contract: ['0xdAC17F958D2ee523a2206206994597C13D831ec7'],
      sig_hash: ['0xa9059cbb'],
      sender: '0xc6cde7c39eb2f0f0095f41570af89efc2c1ea828',
      origin: '0x36928500bc1dcd7af6a2b4008875cc336b927d57',
      include_events: true
    },
    {
      limit: 1
    }
);
 
for await (const call of internalTransactions) {
    console.log(call);
}
