The D11K CRYPTO package is a crypto package used by all D11K clients.

D11K-CRYPTO encrypts a master phrase to a keystore. This keystore can then be exported to other D11K wallets or stored securely.

Users can export their phrase and import them into other wallets since it is a BIP39 compatible phrase.


  • Install @d11k-ts/crypto from npm
yarn add @d11k-ts/crypto


yarn build


yarn test
