Credit cards and traditional bank accounts have been used for years as the only way to transact. However, this centralised approach comes with multiple privacy and control issues as banks can access, share, and manage user personal and financial information.

Then, cryptocurrencies emerged as the modern way to send and receive money. With decentralised storage spaces, transfers have become safer and more transparent, providing users with more control.

However, understanding their notions and how they work can be challenging due to the advanced technology embedded in them. Let’s overview what a wallet address is and how it plays a role in safeguarding your digital money.

Key Takeaways

• Wallet addresses are unique storage identifiers used to send and receive crypto transactions.

• Each wallet has its own address and private keys, which ensure authorised access and prevent hacking.

• Addresses are between 12 and 24 characters generated based on 64-character long private keys and using hashing protocols.

What is a Wallet Address?

A crypto wallet’s address is a unique string of characters (numbers and letters) that act as a digital location for transferring digital assets.

Similar to a traditional bank account’s IBAN number, the crypto wallet address is a special identifier used to locate transactions, track activities, and boost blockchain transparency.

Each cryptocurrency has its own wallet type, with formats varying across different blockchain networks. They typically consist of long alphanumeric strings derived from cryptographic public keys that are randomly allocated. This makes it harder for hackers to breach through and ensures that no two users have the same address.

Some apps utilise QR codes for convenience, which can be scanned to send funds and copy transaction destinations quickly.

Unlike traditional bank accounts, DeFi wallets do not store or reveal user personal information, ensuring utmost privacy. However, once linked to an identity, transactions can be traced on the blockchain.

Types of Crypto Wallets

There are different types of crypto wallets, and each comes with different security traits, accessibility, and convenience. Many users are concerned about connecting their crypto storage with brokerage and exchange platforms, which makes offline storage preferable for privacy-aware users.

Hot Wallets

These are online connected storage spaces that facilitate quick transactions for transferring virtual funds and investing in cryptocurrencies.

Users can manage their funds through online platforms, making hot wallets more convenient but prone to cyber threats. Some examples include:

• Web wallets: Accessible through browsers (Coinbase).

• Mobile wallets: Downloadable apps on mobiles (Trust Wallet).

• Desktop wallets: Installed locally on computers (Exodus).

Cold Wallets

These are not connected to the internet, and funds are stored offline, offering better security against hacking. However, they are less convenient for sending and managing digital assets, requiring physical access for transactions. Examples include:

• Hardware wallets: Physical devices, similar to USB flash drives, that securely store private keys offline. (Ledger).

• Paper wallets: Physical printouts of addresses and private key details. (bitaddress.org)

How Does Wallet Address in Crypto Work?

The crypto wallet address is a unique identifier that helps distinguish transactions on the blockchain for better tracking and transparency. Here’s how the address is generated:

1. A private key is generated as a random string of characters and the most sensitive detail because it grants complete control. They typically include 64 characters, 256-bit hexadecimal format:

2. A public key is created based on the private key using special cryptography to secure the relationship between both keys. They typically include 130 characters, 512-bit hexadecimal format.

3. The wallet address is generated after public keys undergo special hashing algorithms to produce a shorter, user-friendly address. They typically follow SHA-256 or RIPEMD-160 hashing and include 40-42 characters.

The resulting address is what users share to receive funds and track transactions on blockchain explorers, while the private key remains confidential and is used to sign transactions when sending crypto.

Cryptographic hashing is immutable, meaning that reverse-processing a private key from a public key or BTC wallet address is impossible. This mechanism makes crypto keys hard to guess and highly safe.

How are Payments Processed?

When a transaction is initiated, the sender enters the recipient’s address and authorises the transfer by signing their private key within the wallet. The transaction is then broadcast to the blockchain network, where miners confirm and record it in a block.

The sender’s public key is used to verify the digital signature created by the private key, proving that the transaction was indeed authorised by the rightful owner without revealing the private key itself.

Once approved, validators add the transaction to the blockchain, making it immutable. Finally, the recipient accesses the funds in their wallet, which are now locked to their own private key.

How to Get a BTC Wallet Address

Creating a crypto wallet is straightforward but might be technically challenging for new users. Here’s how you can start:

1. Choose a Wallet Type: Decide between software (hot storage) like Coinbase or hardware (cold storage) like Ledger. The choice depends on your required security level and usage.

2. Download & Set Up: Install the wallet on your smartphone or desk or configure the hardware device.

3. Create a New Wallet: The wallet will generate a public address and private key, which you must carefully store safely.

4. Recovery Data: The wallet will generate the seed phrase — 12 to 24 simple words used to recover and access your storage.

5. Get Your Address: You will have a unique address for each cryptocurrency to share to receive crypto transfers.
