What Is A Seed Phrase And How Does It Secure Your Cryptocurrency?

Account abstraction is an emerging narrative wherein cryptogrpahers and developers are innovating to power wallet creation, access, and recovery mechanisms without the need for seed phrases. BIP-39 defined a specific list of 2048 words and a deterministic algorithm for generating seed phrases, ensuring compatibility across different wallets and platforms. Now, remembering a long string of random characters like “a1b2c3d4…” would be difficult and error-prone for most people. Instead, the vault provides you with a set of simple, everyday words — your seed phrase — that, when used together, can recreate that complex code. Recording multiple private keys accurately and storing that record offline is not as easy as it seems. Anyone managing multiple accounts needs a wallet capable of storing multiple strings of characters without mistakes.

How Did Seed Phrases Emerge As A Solution?: The Origin Story

The backup seed phrase comes back into play if the user loses the device. In that event, the user should ideally have stored that seed phrase in a location separate from the cryptocurrency wallet. They would then use it to restore access on another compatible device. One of the most widely-used standards for seed phrases is BIP39 (Bitcoin Improvement Proposal 39). And while it was initially proposed for bitcoin wallets, it became a popular standard across the board. It outlines how crypto wallets generate the phrase and reinterprets each word for wallet recovery.

Mobile wallets can benefit from this approach because it prevents the entire private key from being stored on the device (a central point of failure). For example MPC wallets like ZenGo store the second key share on their servers. So, theoretically, if a hacker was only able to acquire one half of the key, they would be unable to approve any transactions without ZenGo’s permission. But unlike the popular multi-signature (multisig) wallets, MPC wallets don’t require multiple individual private keys to sign a signature.

Your Secret Private Key Recovery Phrase

This means not sending it to yourself in an email or texting it to a friend. Investing in cryptocurrency can be empowering; however, with great power comes great responsibility. A seed phrase needs to be kept a secret at all costs, as anyone who knows your seed phrase can import a copy of your wallet onto their own device and empty it. They can do so because knowing your seed phrase gives them access to your private keys. Through this seed phrase your cryptocurrency ‘wallet’ can generate a series of ‘private keys’ that allow for the trade and sale of your cryptocurrency.

How can I keep my seed phrase safe?

However the two serve different functions, and it’s important to know the difference. Since your seed phrase is the only way to recover your crypto assets if you lose access to them, it’s worth as much as they are, so it should be treated accordingly. The piece of paper or metal with your seed phrase should be stored like any other valuables you own, whether in a safe at home, at the bank or in a secret hiding place. A seedless wallet is a type of crypto wallet that does not rely on a single seed phrase for account creation and recovery.

Treating it with utmost care and following the do’s and don’ts will help ensure the safety and security of your digital assets. When you set up a wallet, the wallet generates a random number called a “master seed.” What is a Seed Phrase This master seed is then encoded into a series of words — the seed phrase. The reason this process is so secure lies in the randomness and the one-way nature of cryptographic hash functions used in this process.

• Seed phrases are perhaps the most impact innovations in web3 that catalyzed mass adoption of blockchain technology.
• Li emphasizes that while MPC is generally a better scheme, it is important to pay attention to the details of the implementation to ensure the best level of security.
• If you’re the only one who knows how to access your seed phrase but you’re indisposed for any reason, nobody else will be able to recover your funds without it.
• This offer is only valid for new users who have not installed the app yet.

A much better solution is storing those private keys offline in a paper or hardware wallet. For example, Ledger devices store your private keys offline and allow you to sign transactions in an environment isolated from your web2 device such as a smartphone or laptop. Offline storage is the only safe solution for storing these keys as it keeps you safe from hackers.
