# TEP-20

## Overview

The TEP20 token standard is a core component of the TAN-chain blockchain, similar to the ERC20 standard in Ethereum. It defines a set of rules and functionalities that a token contract must follow to ensure compatibility and interoperability across the TAN-chain ecosystem.

## Key Features of TEP20

* **Transferable**: Tokens can be transferred from one account to another.
* **Transfer Approval**: A token owner can approve another account to transfer tokens on their behalf.
* **Balance Query**: The balance of any account can be queried.
* **Allowance Query**: The amount of tokens that an owner allowed to a spender can be queried.

## Use Cases

* **Digital Currency**: TEP20 tokens can represent any fungible assets such as currencies, points, or in-game items.
* **Fundraising**: Used in Initial Coin Offerings (ICOs) or token sales.
* **Staking and Rewards**: Can be used in various decentralized finance (DeFi) applications for staking and reward distribution.

## Deploying TEP20 Token Contracts

There are several methods to deploy a TEP20 token contract on the TAN-chain network.
