Understanding crypto wallet addresses is essential for anyone entering the world of digital currencies. These unique identifiers act as your personal gateway to sending and receiving cryptocurrencies across various blockchain networks. While they may look like random strings of characters, each address follows specific formatting rules depending on the network it belongs to.
In this guide, we’ll break down the most common types of crypto wallet addresses, how they differ across major blockchains, and what to look for when identifying them. Whether you're new to crypto or expanding your knowledge, this overview will help you navigate transactions with confidence.
Understanding Crypto Wallet Addresses
A crypto wallet address is a digital identifier used to send and receive cryptocurrency. It’s generated through cryptographic algorithms and is unique to each user. Think of it like an email address—but instead of receiving messages, you receive digital assets.
Wallet addresses are derived from public keys, which themselves come from private keys. While your private key must remain secret, your wallet address can be safely shared to receive funds. All transactions linked to a wallet address are permanently recorded on the blockchain, making them transparent and traceable.

Common Types of Bitcoin Wallet Addresses
Bitcoin supports several address formats, each developed at different stages of the network’s evolution. Here are the four most widely used types:
Segwit (Bech32) Addresses
Bech32 addresses are the modern standard for Bitcoin transactions. They begin with bc1 and are optimized for efficiency. By reducing the data size per transaction, they lower fees and improve network scalability.
Example: bc1d42UNb54eBiGm0qEM0h6r2h8n532to9jtp186ns
These addresses are fully compatible with Segregated Witness (SegWit), a protocol upgrade that separates signature data from transaction data. Most wallets now default to generating Bech32 addresses due to their cost-effectiveness.
Legacy (P2PKH) Addresses
The original Bitcoin address format, P2PKH (Pay-to-Public-Key-Hash), starts with a 1. While still functional, these addresses are less efficient because they result in larger transaction sizes and higher fees.
Example: 17g24tOg1URxOylEyt9v3Nps5T8CKe2Gyd
Though largely outdated, you might still encounter P2PKH addresses when interacting with older services or users who haven’t upgraded their wallets.
Compatibility (P2SH) Addresses
P2SH (Pay-to-Script-Hash) addresses start with a 3 and were introduced to support advanced features like multi-signature wallets. These require multiple parties to approve a transaction, adding an extra layer of security—ideal for shared accounts or corporate use.
Example: 3T74h2ClRP93NOwAviersyiWkqpHcLYBs
While not as common for everyday users, P2SH addresses remain important for complex financial setups.
Taproot (BC1P) Addresses
The newest addition to Bitcoin’s address family, Taproot addresses start with bc1p. They enhance privacy by making all transaction outputs look similar, regardless of whether they involve simple transfers or complex smart contracts.
Example: bc1prwgcpptoxrpfl5go81wpd5qlsig5yt4g7urb45e
Taproot also unlocks more sophisticated scripting capabilities on Bitcoin, paving the way for future innovations. However, not all wallets currently support this format.
Ethereum and ERC-20 Token Addresses
Ethereum addresses follow a consistent format: they always start with 0x and consist of 40 hexadecimal characters (excluding the prefix). This structure applies not only to ETH but also to all ERC-20 tokens, such as stablecoins like USDT or USDC.
Example: 0x7f533b5fbf6ef86c3b7df76cc27fc67744a9a760
To make these long strings more user-friendly, services like Unstoppable Domains allow users to create human-readable aliases (e.g., yourname.crypto). This improves usability without compromising security.
Ethereum’s uniform addressing system simplifies interactions across decentralized applications (dApps), exchanges, and DeFi platforms.

Other Major Cryptocurrency Address Formats
Beyond Bitcoin and Ethereum, other prominent cryptocurrencies have their own distinct address conventions.
Litecoin (LTC)
Litecoin addresses vary based on type:
- Legacy: Start with
LorM - P2SH: Begin with
3 - Bech32: Start with
ltc1
Example: ltc1qzvcgmntglcuv4smv3lzj6k8szcvsrmvk0phrr9wfq8w493r096ssm2fgsw
Like Bitcoin, Litecoin has adopted SegWit for improved efficiency.
Bitcoin Cash (BCH)
Bitcoin Cash originated as a fork of Bitcoin, so early BCH addresses resembled BTC’s (starting with 1 or 3). However, newer formats use prefixes like q or p.
Example: qrvax3jgtwqssnkpctlqdl0rq7rjn0l0hgny8pt0hp
When sending BCH, ensure your wallet correctly identifies the network to avoid lost funds.
Dogecoin (DOGE)
Dogecoin addresses start with a capital D, followed by a letter or number. They are based on Litecoin’s codebase and support similar functionalities.
Example: D7wbmbjBWG5HPkT6d4gh6SdQPp6z25vcF2
Despite its meme origins, Dogecoin remains widely used for microtransactions and tipping online.
Frequently Asked Questions (FAQ)
Q: Can I use the same wallet address for different cryptocurrencies?
A: No. Each blockchain uses unique address formats. Sending crypto to an incompatible address may result in permanent loss of funds.
Q: Are wallet addresses reusable?
A: Technically yes, but for privacy reasons, it's recommended to use a new address for each transaction if your wallet supports it.
Q: What happens if I send crypto to the wrong address?
A: Blockchain transactions are irreversible. Always double-check the recipient address before confirming any transfer.
Q: How do I know which address format my wallet uses?
A: Most modern wallets automatically generate the optimal address type (e.g., Bech32 for Bitcoin). Check your wallet settings or documentation for details.
Q: Is it safe to share my wallet address publicly?
A: Yes. Your wallet address is designed to be shared for receiving payments. Just never share your private key or recovery phrase.

Final Thoughts
Crypto wallet addresses are more than just random character strings—they’re carefully structured identifiers that ensure secure and accurate transfers across decentralized networks. From Bitcoin’s evolving formats to Ethereum’s standardized approach, understanding these differences helps prevent costly mistakes.
As blockchain technology advances, expect further improvements in usability, privacy, and interoperability. Staying informed about address types and best practices is key to navigating the crypto ecosystem safely.
Whether you're receiving your first satoshi or managing a diversified portfolio, knowing how to identify and use the right wallet address empowers you to take full control of your digital assets.
