Set up tap-trading
Give this browser a limited buying key, then manage or revoke it.
Tap-trading lets this browser place supported buys without opening the owner wallet for every order. You first approve a limited browser key and a budget held in Trading Balance.
The key can buy within its limits. It cannot withdraw your balance. Its permission expires at the time you choose.
Arm a session
- Connect the wallet that owns the funds.
- Open tap-trading in the header and choose Arm tap-trading.
- Expand Adjust the caps if you want to change the defaults.
- Set Per tap, Per day, Open Windows, Dearest odds, Expires in and Deposit now.
- Read What you are signing. Check the key, amount, price ceiling and expiry.
- Choose Arm tap-trading and complete the wallet prompts. Setup may include token approval, deposit/grant and funding the key's gas.
- Check the manager's armed state and remaining budget before placing a ticket.
The caps work together. A large remaining budget does not override a small per-tap limit, daily limit or maximum number of open Windows.
Who pays gas?
The current deployment may sponsor eligible session transactions. When sponsorship is unavailable, the browser key needs STT. The manager reports the key's gas state and lets you top it up when supported.
Owner setup transactions can still need STT. An armed label is not a promise that every action in the app is gas-free.
Stop or replace a key
| Action | Effect |
|---|---|
| Revoke | Stops this grant from making future buys. Unspent budget becomes available in Trading Balance. Existing positions remain yours. |
| Re-key | Replaces the session's browser key through owner authorization. Use it if the local key is missing or needs replacing. |
| Forget this key | Removes the local copy from this browser. It does not revoke the chain permission. |
Revoke before forgetting a key you no longer intend to use. Clearing browser storage is not a substitute for revocation.
Limits reached or session missing
If an order is blocked, inspect remaining budget, per-day headroom, open Windows, allowed price, expiry and key gas. Fund or change only the constraint you intend to change, then review the updated permission.
A new browser does not automatically have the old browser key. Reconnect the owner wallet and use Re-key. A Duel has a separate match-key recovery flow.
See balances for withdrawals and agent permissions for how these limits fit into the system.
