Icon Linkgenerate

generate(size?, extraEntropy?): string

Create a new mnemonic using a randomly generated number as entropy. As defined in BIP39, the entropy must be a multiple of 32 bits, and its size must be between 128 and 256 bits. Therefore, the possible values for strength are 128, 160, 192, 224, and 256. If not provided, the default entropy length will be set to 256 bits. The return is a list of words that encodes the generated entropy.

Icon LinkParameters

NameTypeDefault valueDescription
sizenumber32Number of bytes used as an entropy
extraEntropyBytesLike ''Optional extra entropy to increase randomness

Icon LinkReturns

string

A randomly generated mnemonic
