Self-custody

Self-custody means you manage the keys to your crypto yourself. You don’t have to rely on a company to hold those keys for you.

What is self-custody?

With self-custody, you manage your own private keys. These are secret digital codes that let you send crypto. A crypto wallet helps you manage these keys and approve transactions.

Crypto isn’t literally stored in your wallet. The blockchain records who has the right to which crypto. Your wallet uses your keys to sign a transaction, after which the network checks whether it’s valid.

Many wallets provide a recovery phrase: a sequence of words you can use to restore your keys. Anyone who has these words can usually access the crypto, too. So keep them safe and don’t share them with anyone.

An example of self-custody

Someone withdraws 0.01 bitcoin from a trading platform to the address of their own hardware wallet. A hardware wallet is a separate device that stores the keys.

Once the transaction is processed on the Bitcoin network, this person can send the bitcoin using their own keys. They don’t need permission from the trading platform. That’s self-custody.

Why is self-custody important in crypto?

Self-custody makes you less dependent on a custodian. This matters if a trading platform blocks withdrawals, gets hacked, or goes bankrupt. That’s why the term often comes up in news about wallet security and rules for personal wallets.

You may also need your own wallet to use a decentralized exchange directly. It’s a place where people can trade crypto without a centralized provider.

Self-custody also comes with personal responsibility. If you lose all your keys and recovery options, you may permanently lose access. Phishing, malicious software, entering the wrong address, or using the wrong network can also lead to loss. A hardware wallet also can’t stop you from approving a harmful transaction yourself.
