# About Tavchain

> Learn what Tavchain is, how its EVM-compatible Layer 1 works, and where to start with testnet applications and node operation.

Tavchain is a general-purpose, EVM-compatible Layer 1 for smart contracts and applications. It provides a shared foundation for developers to build services that help people, businesses and institutions transact, verify information and collaborate.

## Why Tavchain

Tavchain's purpose is to support useful applications shaped by Africa's needs and available to users worldwide. The platform is open to different industries and application ideas, with Solidity and familiar Ethereum tools as the starting point.

## What you can build

* Payments and commerce applications, including contract-based escrow and payment rules.
* Finance and DeFi applications, including token exchanges and lending contracts.
* Tokens, memberships, games and other digital-asset applications.
* Document-verification and shared-record applications for businesses and institutions.

These are application categories developers can build toward, not a list of services already operated by Tavchain. Each application needs its own implementation and security review. Services involving money, identity or physical assets also need appropriate providers, data and legal arrangements.

Use Tavchain Testnet to develop your application with Solidity, Ethereum-style accounts and EVM development tools.

Read the [whitepaper](https://docs.tavchain.safeney.com/tavchain/whitepaper.md) for the platform design, participation model and development direction.

## How Tavchain works

The node application derives from Cronos 1.8.1 and uses the Cosmos SDK, CometBFT-family consensus and EVM execution. Applications connect through Ethereum JSON-RPC. Native node tooling uses a separate chain identifier and address representation.

## Use the testnet

Tavchain Testnet supports native TAV transfers, Solidity contract deployment and interaction, and ERC-20 development. Use the faucet for valueless Test TAV to pay transaction fees.

* [Connect a wallet](https://docs.tavchain.safeney.com/tavchain/connect.md) and [send a transfer](https://docs.tavchain.safeney.com/tavchain/first-transfer.md).
* [Build and deploy a contract](https://docs.tavchain.safeney.com/tavchain/contracts.md).
* [Run a non-validator full node](https://docs.tavchain.safeney.com/tavchain/operate.md).

The initial validators remain under shared administration. The network uses native TAV staking, delegation and governance; active validator membership depends on bonded stake and the configured set size.
