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:

1. Withdrawal key: m/12381/3600/account_index/0
   
2. 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.
