In the wake of Bitcoin's rise to prominence, blockchain technology—the foundation of Bitcoin—has also gained significant attention. As Bitcoin became a new favorite in financial markets, other cryptocurrencies emerged rapidly. The diversification of cryptocurrencies has attracted an increasing number of participants to the market. With the market's growth, many individuals now own and trade cryptocurrencies.
As digital currencies gain wider acceptance, more investors are entering the space to capitalize on their value. However, investing in digital currencies requires specialized tools, notably encrypted digital currency wallets. Since digital currencies are virtual assets, they rely on professional wallets for storage, sending, and receiving. Encrypted digital currency wallets provide essential financial functions such as creating wallet addresses, transferring digital currencies, and querying transaction histories for each address.
What Is a Software Wallet?
A software wallet generates one or more wallet addresses based on cryptographic principles. Each wallet address corresponds to a key pair: a private key and a public key. The public key is derived from the private key through mathematical operations and is uniquely paired with it. The public key is primarily used for external transactions, while the private key is required to sign transactions, proving ownership and control over the assets in the wallet address.
Wallet Address
A wallet address is a 42-character hexadecimal hash string that serves as a unique identifier for a wallet. It cannot be modified, and all tokens within the same wallet share the same address for transfers and receipts. For example, the address for receiving ETH and EOS in a single wallet remains identical. This differs from trading platforms, where addresses often vary for different tokens. Therefore, verifying the correct address is crucial when transferring tokens to an exchange. Wallet addresses can receive various cryptocurrencies and act as proof of transfer.
Wallet Password
During wallet creation, users set a password comprising at least eight characters. This password serves two purposes: authorizing transfers and logging in when importing a wallet using a keystore. A wallet can have different passwords on different devices, each operating independently. For instance, if you set a password on Phone A and import the same wallet to Phone B with a new password, the password on Phone A remains functional. If you forget your password, you can import the wallet to another device and set a new password without losing access to your assets.
Private Key
After creating a wallet, users can export the private key by entering their password. The private key is a plaintext string of 64 characters and is unique to the wallet. It cannot be changed. The private key is critical because whoever possesses it controls the wallet and its assets.
Recovery Phrase (Seed Words)
During wallet setup, users can back up a recovery phrase—a sequence of 12 words separated by spaces. This phrase is generated after entering the password and is unique to the wallet. The recovery phrase is essential as it represents another form of the private key, offering the same functionality. When importing a wallet, entering the recovery phrase and setting a new password (without the original password) grants full control, allowing the transfer of tokens.
Keystore (Encrypted Private Key)
When importing a wallet using a keystore, users must enter the keystore and the original password set on the device. This differs from using a private key or recovery phrase, where the original password isn't required, and a new password can be set directly.
For users, backing up the private key and recovery phrase is crucial, as both are vital for wallet security. The keystore is also important, but it requires the original password for access. To enhance asset security, many experts recommend using centralized wallets over decentralized ones, as the latter lack regulatory oversight and pose higher risks.

Frequently Asked Questions
What is the difference between a wallet address and a public key?
A wallet address is a shortened, hashed version of a public key used for receiving funds. The public key is derived from the private key and is used to generate addresses. While the public key can verify signatures, the address is the identifier shared for transactions.
Can I change my wallet address?
No, a wallet address is permanently tied to your wallet and cannot be changed. However, you can create new wallets with new addresses if needed.
What happens if I lose my recovery phrase?
Losing your recovery phrase means you may permanently lose access to your wallet and assets if you also forget your password and lose access to your private key. It is essential to store the recovery phrase securely offline.
Are centralized wallets safer than decentralized wallets?
Centralized wallets are often considered safer for beginners because they are managed by organizations that implement security measures and regulatory compliance. Decentralized wallets offer full user control but require users to manage their own security, which can be riskier if not handled properly.
Can I use the same password for multiple wallets?
While technically possible, using unique passwords for each wallet enhances security. If one wallet is compromised, others remain protected.
How often should I back up my wallet?
You only need to back up your wallet once during initial setup. However, if you generate new addresses or keys, ensure they are included in your backup. Regularly verify that your backup is accessible and secure.
