Security and Architecture
eth2keymanager is the entry point to manage all operations, in it sits a unique wallet and accounts.
eth2keymanager <- Wallet <- [Accounts]
An account is the entity that ultimately signs transactions.
Wallets and accounts are derived according to EIP-2334:
- Withdrawal key: m/12381/3600/account_index/0
- Validation key: m/12381/3600/account_index/0/0
The seed is needed just to execute specific operations like creating new accounts or signing with the withdrawal key.
