Analyzing All Transactions To and From an Address

Introduction​

Understanding all transactions to and from an address is an interesting use case. Traditionally extracting this information would be very difficult with an RPC. In this tutorial, we'll introduce you to the evm-address-summary tool, which uses HyperSync to efficiently extract all transactions associated with a specific address.

About evm-address-summary​

The evm-address-summary repository contains a collection of scripts designed to get activity related to an address. These scripts leverage HyperSync's efficient data access to make complex address analysis simple and quick.

GitHub Repository: https://github.com/enviodev/evm-address-summary

Available Scripts​

The repository offers several specialized scripts:

  1. All Transfers: This script scans the entire blockchain (from block 0 to the present) and retrieves all relevant transactions for the given address. It iterates through these transactions and sums up their values to calculate aggregates for each token.

  2. NFT Holders: This script scans the entire blockchain and retrieves all token transfer events for an ERC721 address. It records all the owners of these tokens and how many tokens they have traded in the past.

  3. ERC20 Transfers and Approvals: This script scans the blockchain and retrieves all ERC20 transfer and approval events for the given address.

It calculates the following:

  • Token balances: Summing up all incoming and outgoing transfers for each token
  • Token transaction counts: Counting the number of incoming and outgoing transactions for each token
  • Approvals: Tracking approvals for each token, including the spender and approved amount

Quick Start Guide​

Prerequisites​

Basic Setup​

  1. Clone the Repository

    git clone https://github.com/enviodev/evm-address-summary.git
    cd evm-address-summary

  2. Install Dependencies

    pnpm install

  3. Run a Script (example with all-transfers)

    pnpm run all-transfers 0xYourAddressHere

For complete details on all available scripts, their usage, and example outputs, refer to the project README.

Customizing Network Endpoints​

The scripts work with any network supported by HyperSync. To change networks, edit the hyperSyncEndpoint in the appropriate config file:

// For Ethereum Mainnet
export const hyperSyncEndpoint = "https://eth.hypersync.xyz";

For a complete list of supported networks, see our HyperSync Supported Networks documentation.

Practical Use Cases​

One powerful application is measuring value at risk for any address, similar to revoke.cash. You can quickly scan an address to find all approvals and transfers to easily determine any outstanding approvals on any token. This helps identify potential security risks from forgotten token approvals.

Other use cases include:

  • Portfolio tracking and analysis
  • Auditing transaction history
  • Research on token holder behavior
  • Monitoring NFT ownership changes
