Set limits for wallet swaps and stay in control of your funds.

Review your permissions
Open Spending permissions in Wallet to see your options. A session is a short-term permission to sign certain swaps. It can save you from opening the wallet window for each swap.
Reading this panel does not grant access to your funds. Set your limits and select Check permission availability. If it is allowed, read the terms, tick the consent box, and select Authorize in wallet.
You can also confirm each swap in your wallet without using a session.
Choose a narrow permission
A session covers one direction: ETH to USDC.e, or USDC.e to ETH. V2 and V3 are two swap routes. A session uses V2. It cannot buy cubes, trade other tokens, or perform unrelated wallet actions. V3 swaps still need your approval in the wallet.
Limits count tokens, not their dollar value. Gas is the ETH used to pay network fees. Setting up or revoking a session has its own network fee. Check all limits before you approve.
- Set a total token limit for the session.
- Set the most tokens one swap can use.
- Set an ETH budget for network fees.
- Choose when access ends: 15 minutes, 1 hour, or 4 hours.
Each swap is still your action
Select Use approved V2 session before you get a quote. This uses the V2 route, whose rate may differ from V3. Get a new quote after choosing this option.
You still select Confirm swap for each trade. The session signs only within your limits. It does not run trades in the background. If USDC.e needs approval, that is a separate step from the swap.
Open Spending permissions to check how much of each limit is left.
Pause or end access
Pause on this device stops the device from using a session. It does not cancel the permission on the network. To end that access, select Revoke in wallet and confirm. Use Refresh status to check that it worked.
The signing key is this tab’s temporary key for approved swaps. Reloading the page or signing out clears that key. It does not cancel the permission on the network. You can still check or revoke a saved permission without that key.
If a request is still being checked, wait before you try to replace it. Never share a private key or recovery phrase to restore a session.
