Non Custodial
Non-custodial (or non-custodial wallet/protocol) means the user alone holds and controls the private keys; no third party, exchange, or company can access, freeze, or move the assets without the user’s cryptographic signature.
✦ Key Insight
It embodies the core crypto principle of self-sovereignty. Traders using non-custodial solutions eliminate counterparty risk from exchange insolvencies or freezes, retaining full ownership and the ability to interact directly with DeFi.
✕ Common Misconceptions
Confusing “non-custodial” marketing with actual key control; losing the seed phrase with no backup; assuming the wallet provider can recover funds; using non-custodial wallets on compromised devices.
Detailed Explanation
How It Works: Private keys (or seed phrases/passkeys) are generated and stored on the user’s device or hardware. Transactions are signed locally and broadcast to the blockchain. The software never has the ability to move funds independently.
