For those who know little about self custody...

Private Key Control: Individuals store their private keys securely, often in hardware wallets, paper wallets, or encrypted digital storage.

Independence: Self-custody allows users to transact and manage their assets without needing to rely on third-party services.

Security Considerations: While self-custody provides greater control, it also places the responsibility of secure storage and backup of private keys entirely on the user. This means taking precautions against loss, theft, or unauthorized access to the private keys.
