@iov/keycontrol

Keycontrol manages all private keys and keeps them safe.

Please stick to using the public API even if you are importing from JavaScript, where private is not enforced.

Getting started

Please see the following documents for how to get started using the @iov/keycontrol classes:

• @iov/multichain README
• @iov/cli README

API Documentation

https://iov-one.github.io/iov-core-docs/latest/iov-keycontrol/

As you see above, everything goes through the UserProfile, which is the main entry point into this package.

The main wallet types you can add are

• Ed25519Wallet, which stores arbitrary Ed25519 keypairs.
• Ed25519HdWallet, which generates HD keys à la SLIP-0010 (BIP-0032), with an arbitrary path (not chain-dependent).
• LedgerSimpleAddressWallet which allows you to connect to a Ledger device for signing BNS transaction.

HD derivation paths

Ed25519HdWallet and Secp256k1HdWallet use SLIP-0010 HD key derivation. The class HdPaths can be used to generate derivation paths.

Coin	Derivation path for account index a = 0,1,…	Code
IOV	m/44'/234'/a'	HdPaths.iov(a)
Ethereum	m/44'/60'/0'/0/a	HdPaths.ethereum(a)
Lisk	m/44'/134'/a'	HdPaths.bip44(134, a)
RISE	m/44'/1120'/a'	HdPaths.bip44(1120, a)
Stellar	m/44'/148'/a'	HdPaths.bip44(148, a)
