What Is a Wallet?
A crypto wallet is a digital tool that allows users to send, receive, and manage cryptocurrencies and tokens on a blockchain. Rather than storing the assets themselves, a wallet stores the private keys that prove ownership and authorize transactions. When a user initiates a transfer, the wallet uses the private key to sign the transaction, which is then recorded on the blockchain.
Crypto wallets can be either custodial or non-custodial. In a non-custodial wallet, the user controls their private keys and is fully responsible for security and recovery. In a custodial wallet, a third-party provider manages the private keys on the user’s behalf, offering convenience, account recovery, and simplified access.
Because private keys determine control of funds, wallet type directly impacts responsibility and risk. Choosing between custodial and non-custodial setups depends on a user’s priorities around control, security, and usability.
KAST operates a custodial wallet model, securely managing private keys within its infrastructure so users can transact and spend digital assets without handling keys directly.
