A self-custody wallet, also called a non-custodial or Web3 wallet, is a cryptocurrency wallet that holds your private keys, giving you full control over stored digital assets like Bitcoin or Ethereum. Self-custody wallets enable peer-to-peer (P2P) crypto transactions and can connect directly with smart contracts, giving access to DeFi applications.
Self-custody wallets, unlike those from centralized exchanges, keep private keys solely with the user and often don’t require registration or KYC verification.
