@graphprotocol/address-book

Contract addresses for The Graph Protocol. This package provides JSON files containing contract addresses for different networks.

Features

• Contract addresses for Horizon and Subgraph Service
• Network-specific deployment addresses
• Zero dependencies

Installation

npm install @graphprotocol/address-book
# or
pnpm install @graphprotocol/address-book

Usage

Import addresses directly

// CommonJS
const horizonAddresses = require('@graphprotocol/address-book/horizon/addresses.json')
const subgraphServiceAddresses = require('@graphprotocol/address-book/subgraph-service/addresses.json')

// ES Modules
import horizonAddresses from '@graphprotocol/address-book/horizon/addresses.json'
import subgraphServiceAddresses from '@graphprotocol/address-book/subgraph-service/addresses.json'

Address format

The addresses are organized by chain ID and contract name:

{
  "1337": {
    "Controller": {
      "address": "0x...",
      "proxy": "transparent",
      "proxyAdmin": "0x...",
      "implementation": "0x..."
    }
  }
}

Development

This package uses symlinks to stay in sync with the source address files. On first install, symlinks are automatically created.

npm Publishing

This package uses a special workflow to ensure address files are included in the published package:

How It Works

Development: The package uses symlinks to stay in sync with source address files:

• src/horizon/addresses.json → symlink to ../../../horizon/addresses.json
• src/subgraph-service/addresses.json → symlink to ../../../subgraph-service/addresses.json

Publishing: npm doesn't include symlinks in packages, so we automatically handle this:

npm publish

Automatic execution:

1. prepublishOnly - Copies actual files to replace symlinks
2. npm pack & publish - Includes real address files in published package
3. postpublish - Restores symlinks for development

Troubleshooting

If publishing fails, the postpublish script may not run, leaving copied files instead of symlinks. To restore symlinks manually:

pnpm restore-symlinks

All symlink management is handled automatically during successful publishes.
