A core wallet is a cryptocurrency wallet built into a network's reference full node software, the best-known example being the wallet in Bitcoin Core. Because it runs a full node, it downloads and checks every block and transaction itself instead of relying on someone else's server, giving the strongest independent verification and better privacy than light wallets. The trade-offs are the disk space, bandwidth and time needed to download and keep the whole blockchain in sync, which is why many users prefer lighter apps or a hardware wallet. Several other coins ship similar "Qt" or core wallets with their node software. Separately, Ava Labs uses the brand name Core for a wallet focused on Avalanche, which is not a full-node wallet in this sense. Also see Non-Custodial Wallet.
