Using a single seed to generate a tree of keys.

HD wallets ushered in a crypto wallet revolution by offering multi-currency support, thus easing account recovery, and improving security and privacy.

You can manage your multiple accounts on multi-chain through seed phrases(a set of words).

Detailed Explanation

A hierarchical deterministic wallet (or “HD Wallet”) is a wallet that generates all of its keys and addresses from a single source.

Deterministic means the keys and addresses are always generated in the same way every time.
Hierarchical means the keys and addresses can be organized in to a tree.

But the best thing about these wallets is that you can generate new public keys without knowing the private keys for them.
