HD wallets enable a series of key pairs to be created from one random seed, providing convenience and manageability as well as high-level security. Understanding Hierarchical Deterministic HD Wallets In the cryptocurrency world, wallets contain keys instead of coins. A cryptocurrency wallet has two keys: a public key or address, which acts much like an account number, and a private key that the holder uses to transfer funds to other accounts.

The private key is much like a password. Someone transferring Bitcoin from their account, for example, would use their private key to authorize the transaction. This combination of public and private keys is designed to ensure security from hackers as well as anonymity in transactions. Because the pair of keys enables the transfer of someone's cryptocurrency, it is critical that the private key remains safe. To this end, the keys are generated randomly. Each key must be backed up in the wallet to prevent it and the funds it is linked to from becoming irrevocably lost to the owner.

But to ensure privacy—one of the purposes driving the creation of Bitcoin and other cryptocurrencies—and limit the use of public keys to one transaction each, a new pair of keys would need to be created for each transaction. This can get difficult to manage over time. Deterministic wallets were created to offer a solution, one in which all keys can be traced back to an original random seed, usually a set of random words, and a hash function. With a deterministic wallet, the original seed is enough to recover all private and public keys, therefore requiring only a single backup at the time of creation.

HD wallets have multi-currency support and can be restored with a recovery phrase. The vast majority of wallets are hierarchically deterministic. They had no relation to each other, which meant you had to back up each key pair individually and keep track of all transaction keys as you bought and sold your crypto.

Since the mids, ND wallets have been largely replaced by hierarchical-deterministic HD wallets. BIP 32 gained popularity with crypto enthusiasts quickly, and numerous wallets with this structure hit the market soon afterwards. This structure solved the problem of users needing to generate their own keys for transactions, which has caused security issues, sometimes resulting in loss of funds.

Unlike its non-deterministic predecessor, all HD wallet addresses can be generated from the master key, thus eliminating the need for storing multiple key pairs. In a HD wallet, the master key pair serves as the foundation, which then branches off into private keys for different cryptocurrencies — and from there goes to key pairs for each transaction. BIP 44 , another Bitcoin Improvement Proposal, created a specific tree structure with multiple account capability.

HD crypto wallets offer stronger privacy than ND wallets because key pairs are derived automatically for every transaction. Because Bitcoin and other blockchains are public ledgers, address balances are public knowledge. Your XPUB can show all of your balances, and therefore should never be shared.

I used an Exchange to purchase some cryptocurrency Your newly purchased bitcoin can now be found in your exchange wallet. You, the user, do not have full authority over the cryptocurrency assets held in this wallet; rather, the exchange does. Exchanges are very appealing targets for hackers since they handle significant amounts of money and hold large amounts of assets across many wallet addresses. To lessen their risk in the extremely unlikely event of a hack, the best cryptocurrency exchanges periodically move their assets to cold storage.

Take a look at the five most reliable places to trade cryptocurrency. Because of the persistent threat of hacking, it is highly recommended that once you have acquired bitcoin, you move the funds to a wallet over which you have complete control. Hacks are less common than they once were, but they still occur. Although staking can be done via an exchange, some hardware wallets provide built-in support for the practice. Tezos, for instance, can be staked using a Ledger hardware wallet.

When storing cryptocurrency, offline and disconnected from the internet in a hardware wallet like the Ledger Nano X or Trezor Model T is one of the safest options because the danger of theft is minimal. If I keep my assets on an exchange, what are the advantages?

On the other hand, there are several unique situations in which you might prefer to keep your assets on the exchange rather than in a wallet: Staking A lot of markets let you choose between hard and soft staking. In hard staking, the staked assets are held for the duration of the staking period and interest is accrued on them; in soft staking, the staked assets can be withdrawn at any time, and interest is accrued on them on a daily basis. KuCoin, Coinbase, and Binance are just some of the best cryptocurrency exchanges that provide both of these services.

Cryptocurrency exchange Events In trading competitions hosted by some markets, the top volume traders of a given asset can win prizes ranging from cryptocurrency to real-world goods like cars and electronics. A number of the leading markets have started hosting events that push the envelope. Because Bitcoin and other blockchains are public ledgers, address balances are public knowledge. Your XPUB can show all of your balances, and therefore should never be shared.

Beyond privacy, HD wallets offer enhanced security because every transaction received is on a different address. And most HD wallets make it difficult, if not impossible, to share confidential information such as your master key pair. Another improvement to HD wallets came with Bitcoin Improvement Proposal BIP 39 , which allowed users to store their master key pairs — and hence their whole wallets — as a recovery phrase.

A recovery phrase is typically a , , or word phrase that must be recorded sequentially and stored safely as a back-up in case you lose access to your wallet or it stops working. This phrase will let you regenerate your wallet and all associated crypto balances. For this reason, it must be stored offline as an absolute secret.

If you lose your recovery phrase — and lose your wallet or forget your PIN — your funds could be lost forever. Ready to put your crypto knowledge to work?
