Use the browser to create or reuse your signing identity, log in with your passkey, and approve secure account setup yourself. Reading this guide does not authenticate you.

​
Start here

  1. Open the authentication and secure setup tutorial and check the venue’s current capabilities.
  2. Reuse your existing identity. If you need a new one, follow only a registration flow listed as available.
  3. Complete the tutorial’s browser passkey ceremony yourself. Keep session credentials private.
  4. Before trading, verify your account’s Canton Party binding is active. Login alone does not establish it.
If a capability is unavailable, an approval is refused, or a result is unclear, stop. Follow the tutorial’s recovery guidance rather than repeating registration or signing.

​
Identity is not account readiness

The human approves every required DFNS User Action with their passkey. A session bearer does not replace that approval. Orders, funding and withdrawals are not part of this guide and require their own authorization and checks. No step here guarantees a successful live flow. Keep credentials and private identifiers in memory, never in command-line arguments, logs, files or chat.
