**Description:**  
When using the “MAX” option in MetaMask to send tokens or interact with smart contracts (especially for staking or DeFi operations), the wallet often selects 100% of the available token balance.  
This leaves the user with **no remaining tokens to cover gas fees** , effectively locking them out of any future on-chain action unless they receive a fresh deposit.

This request is to implement an **optional “Auto-Reserve Gas” toggle** , which would automatically subtract a small buffer (e.g. 0.005 ETH, 0.1 MATIC) from the MAX amount when activated.

* * *

**Purpose:**

- Prevent users from unintentionally staking/sending all their tokens and getting stuck without gas.
- Improve UX and safety, especially for:
  - New users
  - Complex DeFi and staking flows
  - Layer 2 networks or alt-L1s with fast TX speeds and low gas fees

- Reduce support requests and frustration due to accidental full balance usage

* * *

**Extension/Mobile/Both:**  
**Both** (ideally unified behavior across platforms)

Best regards,  
Denis
