Cosmos SDK / PersistenceCore Keyring Helper

Usage

NewCosmosKeyring(opts ...ConfigOpt) (sdk.AccAddress, keyring.Keyring, error)

Options are:

• WithKeyringDir option sets keyring path in the filesystem, useful when keyring backend is file.
• WithKeyringAppName option sets keyring application name (used by Cosmos to separate keyrings)
• WithKeyringBackend sets the keyring backend. Expected values: test, file, os.
• WithKeyFrom sets the key name to use for signing. Must exist in the provided keyring.
• WithKeyPassphrase sets the passphrase for keyring files. The package will fallback to os.Stdin if this option was not provided, but passphrase is required.
• WithPrivKeyHex allows to specify a private key as plaintext hex. Insecure option, use for testing only. The package will create a virtual keyring holding that key, to meet all the interfaces.
• WithMnemonic allows to specify a mnemonic pharse as plaintext hex. Insecure option, use for testing only. The package will create a virtual keyring to derive the keys and meet all the interfaces.
• WithUseLedger sets the option to use hardware wallet, if available on the system.

Testing

go test
