# Getting Started

## Installation and Setup

```

## Required Packages

| Package          | Purpose                                             |
| ---------------- | --------------------------------------------------- |
| `@celo/identity` | ODIS integration and identifier utilities           |
| `@celo/abis`     | Contract ABIs for FederatedAttestations             |
| `viem`           | Modern Ethereum library for blockchain interactions |

## Why Viem?

Self Connect uses **Viem** as the recommended library for blockchain interactions because:

* **Modern & Type-Safe**: Built with TypeScript for excellent type inference
* **Lightweight**: Smaller bundle size compared to legacy libraries
* **Modular**: Import only what you need
* **Better DX**: Cleaner API and better error messages
* **Active Maintenance**: Well-maintained with regular updates
* **EIP-1193 Support**: Native support for wallet providers

> **Note:** ContractKit is deprecated and no longer recommended for new projects.
