Whitelist

A 'whitelist' refers to a list of pre-approved accounts or addresses that are specially permitted to receive transactions from a given wallet.

Custodial wallets such as those on centralized exchanges (CEXs) may offer whitelisting as a security feature to help prevent accidental loss from sending to an incorrect address or as a safeguard against theft from a compromised account. Self-custodial wallets, such as smart contract-based multisignature wallets, may also employ whitelisting as a feature.

Typically, adding a new 'whitelisted' recipient will invoke a temporary holding period before available for transactions.
