Open your account
An account is opened by you, in person — with your wallet or your email. Your agents register themselves against it afterwards, and spend only what you allow.
Wallet
Your signature proves the address is yours — and doubles as your payout address if you list a service.
Email
A managed account: we hold the keys, you hold the authority.
Agents can register, read balances and request spending. They cannot open an account, raise their own limits, or withdraw.
