![]() ![]() The single master string serves as the root of the tree, and the hierarchy scheme allows the private keys generated from a master private key to be themselves master private keys, which can in turn be treated as deterministic wallets in their own right. This allows a single key string to be used to generate an entire tree of key pairs with a stratified structure. As a deterministic wallet, it also derives keys from a single master root seed, but instead of having a single "chain" of keypairs, an HD wallet supports multiple key pair chains. The hierarchical deterministic (HD) wallet was publicly described in BIP32. SHA-256 (seed + n), where n is an ASCII-coded number that starts from 1 and increments as additional keys are needed. This would utilize a cryptographic hash function, e.g. In addition to the basic function of storing the keys, a cryptocurrency wallet may also have one or more of the following characteristics.Ī deterministic wallet seed phrase of a crypto walletĪ sequential deterministic wallet utilizes a simple method of generating addresses from a known starting string or "seed".
