While there are many types of wallets you can use to store your crypto, they can broadly be categorized as custodial wallets and non-custodial wallets.
Custodial wallets hold private keys on your behalf and require trust in a third-party custodian to manage your cryptocurrencies. While this reduces personal responsibility, it also means you don’t have full control over your assets.
Non-custodial wallets, however, give you complete control over your private keys—and therefore your crypto.
What Is a Non-Custodial Wallet?
A non-custodial wallet (or self-custody wallet) is a cryptocurrency wallet that lets you store and transfer digital assets without relying on a centralized intermediary. These wallets interact with:
- DeFi protocols
- dApps
- Blockchain networks
They use a private key (like a password) and a public key (like an account number) to secure and execute transactions.
Key Concepts:
- Private Key: Grants access to your wallet.
- Public Key: Used to receive crypto.
- Seed Phrase: A 12–24-word backup that restores access to your wallet if lost.
