A wallet address is a unique string of characters used for sending and receiving cryptocurrency. If you are new to the crypto space, you will often come across a number of terms—blockchain, cryptocurrency, NFTs, and now wallet addresses—and it can be overwhelming. In this blog post, we’ll break down what a wallet address is in the simplest way possible and explain how to generate and use one. Stay tuned!
Key Takeaways:
- Cryptocurrency wallet addresses are unique identifiers linked to crypto wallets for sending and receiving digital assets.
- Each cryptocurrency has a unique address format, making it easy to identify which digital asset a wallet address is connected to.
- A wallet address is generated automatically whenever you create a crypto wallet.
What is a Wallet Address?
A wallet address is an identifier that allows you to safely send and receive cryptocurrencies and non-fungible tokens (NFTs) via the blockchain network.
It is made up of randomly generated alphanumeric sequences that correspond to each cryptocurrency on the blockchain. You can think of wallet addresses as similar to account numbers for bank accounts, but instead, they are linked to crypto wallets and consist of a much longer and more diverse string of characters.
For instance, Bitcoin wallet addresses tend to begin with “1,” “3,” or “bc1.” On the other hand, Ethereum addresses are 40 characters long (excluding prefixes) and usually start with “0x.” In addition, TRON addresses contain 42 characters and begin with “T.”
What is a Wallet Address Used For?
Essentially, you can use your wallet address to send and receive cryptocurrencies and other digital assets, much like you would use an account number. Let’s dive into the specific uses of a wallet address:
Sending Cryptocurrency
You need a crypto wallet address to send cryptocurrencies. This is because a wallet address serves as the identity of a wallet. However, wallet addresses are usually long and filled with random characters, making them difficult to memorize or input manually. So, make sure to copy the address, and if possible, scan a QR code instead.
Receiving Funds
You can only receive funds into your crypto wallet by giving out your wallet address. To receive cryptocurrency, NFTs, or other digital assets, you need to copy your digital wallet address and provide it to the sender. Otherwise, they won’t have any other way of identifying your wallet. Make sure you copy your address correctly. Most exchanges allow you to send your crypto address directly through messaging apps. Sending the wrong address can result in the loss of funds, which is especially dangerous since crypto transactions are irreversible.
Verifying Crypto Transactions
Since all transactions are recorded on the blockchain, you can use a digital wallet address to verify that a transaction actually occurred. To do this, you can search the wallet identifier on a blockchain explorer, which will show the transaction history, including the sender, receiver, and amount of cryptocurrency involved.
Tracing Crypto Transactions
Similar to verifying transactions, once you have a wallet address, you can trace all outgoing and incoming transactions linked to that address. This can be useful for tracking the flow of funds and ensuring transactions are legitimate. Blockchain explorers allow you to view detailed transaction information, which can help verify the status of a payment or detect suspicious activity.
How to Generate a Wallet Address
Wallet addresses are generated from public keys. Crypto wallets have two types of keys: public and private keys. While private keys enable you to access the funds in your digital wallet, public keys allow you to send and receive crypto (and other digital assets) from others.
Your wallet automatically generates wallet addresses, so you don’t need to create one manually. A crypto wallet is a digital tool for storing, sending, and receiving cryptocurrency. Although all cryptocurrencies are stored on the blockchain, crypto wallets grant you access to the cryptocurrencies you own.
Here’s How to Set Up a Wallet Address:
1. Choose a Wallet Type:
There are different types of wallets, including hot and cold wallets, as well as custodial and noncustodial wallets. Each wallet type has its pros and cons, although most people use hot wallets because of their flexibility and ease of transacting. Some wallets also double as crypto exchanges. Coinbase, Kraken, and Mular are among the most reliable crypto wallets.
2. Create an Account:
You can create an account after choosing your preferred wallet. Fill in the required information, including your name, email address, and other identifiers. If you are using Mular, you will need to complete a KYC process to keep your account secure.
3. Copy Your Wallet Address:
Depending on the crypto wallet you choose, your wallet address usually appears when you’re carrying out a transaction. If you are using Mular, you can select the “Fund” option on your dashboard. This will allow you to choose which cryptocurrency you want to receive, from Bitcoin to Ethereum, USDT, and Solana. Select the cryptocurrency you would like to receive and copy the address.
4. Start Receiving Crypto Payments:
After copying your wallet address, you can send it to the person you want to receive cryptocurrency from. The address must be correct, as your funds may be lost otherwise. With Mular, you can send your wallet address directly through a messaging app like WhatsApp or Twitter. Alternatively, you can send a QR code for the sender to scan.
Types of Wallet Addresses + Examples
Each cryptocurrency has its unique address format, although sometimes the differences are subtle. Familiarizing yourself with different wallet addresses will help you quickly identify which cryptocurrency an address is linked to by observing how the characters are arranged. Here are the types of wallet addresses and examples:
SegWit or Bech32 Address:
SegWit or Bech32 addresses are commonly used in the Bitcoin network. Why? They are designed to improve scalability and reduce transaction sizes, usually resulting in lower transaction fees. These addresses begin with “bc1” and are in lowercase, which helps distinguish them from other wallet addresses. Here’s an example:
bc1qar0srrr7kwnmchctk8xvtyg3l3gx6qvkmzt24p
Taproot Wallet Address (P2TR):
Taproot addresses are a newer format designed to be more secure, scalable, and flexible. They are case-sensitive and typically begin with “bc1p.” While Taproot addresses aren’t as widely compatible as SegWit addresses, they offer unique benefits, such as the ability to create more complex smart contracts. Here’s an example:
bc1pzyf8r2q5mqlu5q0dms5f5j3wpc6mdr2gnzv4du
Legacy P2PKH Address:
Legacy P2PKH addresses are the original Bitcoin addresses and are used in Pay-to-PubKey-Hash (P2PKH) transactions. They begin with the number “1” and are case-sensitive. They also exclude characters that are easily confused with others, such as “0,” “O,” “I,” and “l.” This helps minimize errors when sending wallet addresses. Legacy P2PKH addresses are widely accepted for sending and receiving Bitcoin, so you don’t need to worry about compatibility. For example:
1A1zP1eP5QGefi2DMPTfTL5SLmv7DivfNa
SegWit (P2SH) Address:
Pay-to-Script-Hash (P2SH) addresses begin with the number “3” and were introduced to address compatibility issues with the earlier Bitcoin legacy addresses. With P2SH, you can securely send cryptocurrency to various address formats, including SegWit and non-SegWit addresses. Here’s what a typical SegWit (P2SH) address looks like:

Crypto Wallet Address FAQs
No, a wallet address is not the same as a wallet ID. While they both help you manage your assets, they serve different purposes. You use a wallet ID to gain access to your wallet, while you use a wallet address to receive crypto payments into your wallet.
It is generally safe to share your crypto wallet address with others. Wallet addresses are specifically designed for sending and receiving crypto payments. Most wallet addresses are secure, and although others can see your transaction history (as all crypto transactions are recorded on the blockchain), they cannot access your funds.
You can verify a wallet address using online tools like Blockchain Explorer and Blockchair. These tools help analyze the format of the address and determine if it is authentic.
The length of a wallet address varies according to the type or format, but they are usually between 26 and 35 characters long.
If you send crypto to the wrong address, your funds will be lost. Crypto transactions are irreversible, so it’s always best practice to double-check a crypto address or scan a QR code before sending.
In most cases, you can’t change your crypto wallet address. Once you create a crypto wallet, it generates an address that’s tied to your public key, which cannot be altered. Although, you can’t change an existing wallet address, you can generate new addresses with the same wallet.
