Ethereum: Wallets vs. addresses

Ethereum Wallets: Understanding the Difference Between Addresses and Wallets

When it comes to cryptocurrency transactions, understanding the role of wallets and addresses can seem complicated. In this article, we’ll break down the difference between wallets and addresses and explore when you should use one over the other.

What is a wallet?

A wallet is an electronic or physical container that stores your cryptocurrency assets, such as Ethereum (ETH). It’s essentially a digital or paper solution for storing your coins. A wallet provides a secure way to manage your cryptocurrencies, allowing you to send and receive payments, store data, and perform other transactions.

What is an address?

An address, on the other hand, is a unique string of characters that represents a specific Ethereum account. Each Ethereum account has a public address that is used to send and receive funds on the Ethereum network. When you create an Ethereum wallet, it generates a set of addresses, including:

• Main wallet address: The primary address associated with your wallet.

• Sub-addresses: Secondary addresses that can be used for specific purposes, such as receiving or sending funds to a third party (e.g., a payment processor).

• Re-entry addresses: Custom addresses that are designed to handle re-entry attacks.

When should you use a wallet instead of an address?

Here’s when you’ll need each:

• Use your main wallet address to:

• Send funds to other wallets or accounts.

• Receive payments from others.

• Store and manage your assets securely.

• Use sub-addresses (or secondary addresses) to:

• Receive funds directly into your wallet.

• Send funds to third-party services such as payment processors, exchanges, or money transfer providers.

• Customize your transactions with specific fees, gas costs, and other details.

Using a Wallet vs. Multiple Addresses

When using a new Ethereum address for each transaction, it is important to understand the following:

• Multiple addresses may incur higher fees: Using multiple addresses can increase the overall transaction costs due to additional gas, network congestion, and potential re-entry attacks.

• Wallet balances are not easily transferred: Once you have used an address for a transaction, its balance is irretrievable. You will need to create new balances using the same address or using a different wallet.

In Brief

To summarize:

• A wallet stores your Ethereum assets and provides a secure way to manage them.

• Addresses represent specific Ethereum accounts that can be used for transactions (main wallet address), receiving payments, or storing data.

• You will usually need to use multiple addresses when creating new transactions.
