Intra-Infra

Project Overview

Intra-Infra is a universal, open-source, public-good indexing generator that supports multiple chains and multiple indexer backends.

Multi-chain indexing is painful because each blockchain ecosystem has its own unique indexing tools, ABIs, IDLs, and architectures. Intra-Infra solves this by providing a unified CLI that automatically generates indexing scaffolds for multiple chains from their respective contract definitions (ABI, IDL, Move modules, Cairo contracts). It is a public-good developer tool designed to accelerate multi-chain dApp development.

Supported Chains

• EVM → The Graph subgraph
• Solana → Anchor IDL → Solana Indexer scaffold
• Sui → Move module → Sui Indexer scaffold
• Aptos → Move module → Aptos Indexer scaffold (Coming soon)
• Starknet → Cairo contract → Starknet Indexer scaffold (Coming soon)
• Filecoin/FVM → ABI → FVM indexer scaffold (Coming soon)

Key Features

• Multi-chain ABI/IDL parsing.
• Automatic code generation.
• Extensible architecture.
• CLI-first developer experience.

Installation Instructions

macOS (Homebrew)

brew install node
npm install -g intra-infra

Linux (apt + nvm)

curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.5/install.sh | bash
nvm install node
npm install -g intra-infra

Windows (Node installer)

1. Download and install Node.js from nodejs.org.
2. Open Command Prompt or PowerShell and run:

npm install -g intra-infra

Installing The Graph CLI

For EVM subgraph generation, you will need The Graph CLI:

npm install -g @graphprotocol/graph-cli
graph --version

Usage Examples

EVM (The Graph Subgraph)

intra-infra generate subgraph-evm --network mainnet --address 0x123... --abi ./Contract.json --name MyEvmIndexer

Solana

intra-infra generate indexer-solana --idl ./idl.json --name MySolanaIndexer

Sui

intra-infra generate indexer-sui --module ./module.json --name MySuiIndexer

Aptos

intra-infra generate indexer-aptos --module ./module.json --name MyAptosIndexer

Starknet

intra-infra generate indexer-starknet --cairo ./contract.json --name MyStarknetIndexer

Filecoin/FVM

intra-infra generate indexer-fvm --network filecoin --address f01234 --abi ./Contract.json --name MyFvmIndexer
