Re:AssureSecurity & custody

Your keys. Your signature. Every time.

is non-custodial by architecture — never a promise. Server-side private keys don't exist by design.

Re:KeyHow custody works

Four keys. Four rules.

One holds your funds, one signs orders, and neither of ours can touch either.

01
Your wallet key

Created in your browser, or brought as your own wallet. It never leaves your device and is the only key that can move funds.

02
The trading key

Protocol-restricted and approved by you. It can place and cancel orders; it cannot withdraw.

03
Withdrawals

Signed by your master wallet, in an explicit confirmation. In v1 funds withdraw only to your own address.

04
Your LLM key

BYOK, sent straight from your browser to the provider. Our servers never see it.

Re:ProveThe honest list

Withdrawals require your master wallet's signature
Impossible
Place an order you didn't sign
Every order is signed client-side, in your browser
Impossible
See your LLM key
BYOK goes browser to provider, never through us
Impossible
Hide a fee in the spread
The flat 2.5 bps builder fee is disclosed in the ticket before you sign
Won't
Re:RiskHonest risk

What's still on you.

Market risk

Perpetual futures carry substantial risk, including liquidation. Non-custodial doesn't make trading safe.

Device security

Your keys live on your device. Protect it the way you'd protect the funds themselves.

Protocol risk

Orders settle on Hyperliquid, a protocol we don't operate. Read the full risk disclosure.

Custody stays with you. Start there.
