Web3 wallet and DEX

What is Web3 and DEX

A Web3 wallet is your personal way to access crypto assets and DEX services. Unlike a regular exchange, there is no classic login and password flow: actions are confirmed by signing inside the wallet.

The main difference between a DEX and a centralized exchange is that funds remain with the user. The platform does not store your assets for you — it only provides an interface for trading and managing them.

When connecting and trading, two signatures are usually required. This is a normal flow: one signature grants trading permission, the second one allows extra fee deduction.

Important

A seed phrase and private keys give full access to the wallet. Never share them with anyone, store them in plain text, or send them in messengers.

Wallets

Some of the most popular Web3 wallets are:

• Atomic Wallet
• MetaMask
• OKX Wallet
• Coinbase Wallet

What to do

1. Install or open a suitable wallet.
2. Save the seed phrase.
3. Check that it is written down and stored safely.
4. Never share the seed phrase, private keys, or device access with anyone.

Basic security

• Never send the seed phrase in chats or email.
• Never enter the seed phrase on unknown websites.
• Never show the private key to other people.
• Use only official apps and extensions.
