What is a characteristic of a noncustodial crypto wallet?

A noncustodial crypto wallet is characterized by the user having complete control over their private keys and funds. One of the defining features of such a wallet is that it can be self-hosted on a user’s device, meaning individuals can download it to their computer or mobile device. This local control allows users to manage their cryptocurrency without relying on a third party, which is a fundamental aspect of noncustodial wallets.

When a user downloads the wallet software, they are not required to entrust their keys or assets to an external service, thereby enhancing security and privacy. This user-centric management is also what differentiates noncustodial wallets from custodial wallets, where a third-party service holds the private keys. Thus, being downloadable to a computer allows users to maintain direct control over their crypto assets, aligning perfectly with the essence of noncustodial wallets.
