# EVM

EVM chains are blockchains that run the **Ethereum Virtual Machine**, allowing them to support Ethereum-style smart contracts and token standards. QSafe Wallet is designed to work seamlessly with all EVM-compatible chains, including mainnets like **Ethereum**, **Polygon**, **Binance Smart Chain**, and testnets like **Holesky** and **Sepolia**.

***

### **Core Compatibility Features**

#### **1. Ethereum-Style Addresses (0x...)**

* All EVM chains use **hexadecimal addresses starting with `0x`**, derived from the public key using **Keccak-256 hashing**.
* Example: `0x3de85289856f88b4a718e53bf9421B1D5cE7E58f`
* These addresses are compatible across all EVM chains — you can use the same wallet address on **Ethereum**, **Polygon**, **BSC**, etc.

#### **2. ERC-20 / ERC-721 / ERC-1155 Tokens**

Q Safe Wallet supports the most widely used token standards in the Ethereum ecosystem:

| Token Standard | Description                                                                                                      |
| -------------- | ---------------------------------------------------------------------------------------------------------------- |
| **ERC-20**     | Fungible tokens (e.g., DAI, USDT, LINK). Used for stablecoins, governance tokens, etc.                           |
| **ERC-721**    | Non-fungible tokens (NFTs), where each token is unique (e.g., CryptoPunks, Bored Apes).                          |
| **ERC-1155**   | Semi-fungible tokens, supporting both NFTs and fungible assets in one contract (used in games and marketplaces). |

**How It Works:**

* You can **send, receive, and view balances** of these tokens directly from the wallet interface.
* The wallet automatically detects known tokens or allows manual import via contract address.

#### **3. Testnets Are Fully Supported**

Q Safe Wallet supports major **EVM testnets like Sepolia, Holesky**, and **BNB Testnet** making it ideal for developers and testers.
