Hello MetaMask Community, I need help with a persistent issue involving the MetaMask browser extension. **Problem: The “Review alert” button is completely unresponsive.** Since November 7, 2026, I have been unable to complete transactions through the Jumper DeFi platform. Everything was working normally until the red “Review alert” button suddenly started appearing. When I click it, nothing happens. The warning details do not open, and I cannot confirm the transaction. **Technical details:** - Platform: Jumper Exchange - Network: Base - Protocol: Aave V3 - Transaction: USDC to aBasUSDC - Contract interaction: LIFI Diamond - Function: swapTokensSingleV3ERC20ToERC20 - MetaMask extension version: 13.55.0 - Operating system: Windows 10 - Browsers tested: Chrome and Brave **Troubleshooting already attempted:** 1. Locked and unlocked MetaMask. 2. Disconnected and reconnected my wallet. 3. Refreshed the DeFi application. 4. Disabled and re-enabled the MetaMask extension. 5. Checked for extension updates. 6. Disabled other wallet extensions to eliminate conflicts. 7. Tested different browsers. Unfortunately, none of these steps resolved the issue. **Additional information:** I have an old pending transaction on Robinhood Chain dated September 22, 2026. However, this is a different network from Base, and my Base transactions continued working normally afterward. I also contacted MetaMask through the official support chat but have not yet received assistance from a human agent. **My questions:** 1. Is this a known MetaMask bug? 2. Could the warning be related to the LIFI or Aave transaction? 3. How can I safely fix the unresponsive button without disabling security protections? 4. Has anyone else experienced this recently? I can provide screenshots if needed. I would appreciate guidance from the MetaMask community and moderators. Thank you. ---

Hi there! Sorry for the difficulty. I tried to replicate this issue, but I was able to supply Base USDC on the Jumper exchange without any issue. I’m also on version 13.55.0 of MetaMask extension on chrome browser. **Note:** On the MetaMask support platform, you can skip the bot’s automatic response by instructing it to link you to a human agent ---

Hello theweb3dave, Thank you for testing this issue. Could you please confirm whether you tested the exact same transaction route? I am trying to convert USDC on Base into aBasUSDC through Jumper’s Aave V3 Quick Deposit feature. The transaction interacts with the LI FI Diamond contract using the swapTokensSingleV3ERC20ToERC20 function. MetaMask displays a red “Review alert” button, but clicking it does absolutely nothing. Since you are using the same MetaMask version and browser, could this be related to the specific transaction, security alert system, or my wallet configuration? Is there any safe way to diagnose why the alert cannot be opened without disabling security protections? Thank you for your help! ---

Hi, I think you’re seeing this warning before signing the transaction when trying to swap USDC for aBasUSDC on the Base network. This is part of MetaMask security system, which warns you before signing so you can make sure you’re interacting with the correct contract. I’m not familiar with aBasUSDC and haven’t used it before, so I can’t confirm whether it’s safe. You can check its liquidity and look into the contract details before proceeding. MetaMask uses information from trusted sources to provide these security warnings. > **[How to manage security alerts to protect your wallet | MetaMask Help Center](https://support.metamask.io/configure/wallet/security-alerts/)** > > Learn how to turn on security alerts to receive warnings about risky transactions and report false positives. Also, the Jumper protocol only supports the available routes and liquidity pools for this token. It can’t guarantee a token’s safety or control which route you choose. ---

By “convert USDC to abasUSDC on Base” I’m assuming you meant depositing USDC on Aave protocol via the jumper exchange on the Base network to receive abasUSDC receipt token? If that’s the case, then that’s the exact same transaction route I tested. But in my case, I didn’t get the alert warning at all and I was able to deposit without any issue. Getting in touch with the MetaMask support will be the best option now. Have you tried instructing the AI bot to link you up with a human agent? ---

When you’re in that “Quick deposit” window, above you’ve got Pay with, and below that its Amount, once you enter it, you get a new Receive, and there you can see the Route its going to take (for instance when i enter a small amount like 5$ i see “SushiSwap Aggregator”, but when i enter at least 10$ i’m offered “Nordstern Finance”..and if i dont like this route, i can click that wheel on top right (settings), and there at the bottom it says “Exchanges” i just disable it, so you can do the same with the one that has that warning, to see if another route doesnt give the same warning…also im curious which exact route you’re offered when you get that “Review alert”… This is “Composer via [LI.FI](http://LI.FI)” route (i didnt go through with it, but it i clicked confirm it would approve and swap it) ![image](https://europe1.discourse-cdn.com/metamask/original/3X/1/b/1bb11e0adb92f47e069694b4a364811c0581d726.png) ---

Hello theweb3dave and MetaMask Community, Thank you for your help. I would like to share some additional information that might help identify the cause of my issue. Over the past several days, I have been using the **Earn feature on Jumper Exchange** , specifically depositing and withdrawing USDC through Aave V3 on the Base network to farm XP points. According to my Jumper dashboard, I have accumulated approximately **$86,815 in deposit volume during November 2026**. My goal was to reach the next $100,000 activity milestone to earn additional XP. I was approximately $13,000 away from reaching that milestone. Yesterday, I continued farming and performed approximately another $10,000 in transactions. I have been repeating these deposits and withdrawals frequently, usually with amounts between **$900 and $960 per transaction**. I estimate that I performed approximately 20 to 30 similar transactions over the past several days. Everything was working perfectly until the evening of November 7, 2026, when MetaMask suddenly started displaying the red **“Review alert”** button. Since then, whenever I attempt the same Aave V3 deposit through Jumper, the button becomes completely unresponsive. Clicking it does absolutely nothing, and I cannot even open the security warning to see what triggered it. **My main questions are:** 1. Could the high frequency of repetitive deposits and withdrawals have triggered MetaMask’s security monitoring system? 2. Is it possible that my wallet or this specific transaction route was temporarily flagged due to the volume or frequency of activity? 3. Does MetaMask have any temporary restrictions, cooldown periods, or automated security mechanisms related to repeated DeFi transactions? 4. Could this simply be a technical bug affecting the security alert interface? 5. If this is a temporary restriction, would waiting help, or is there another safe way to resolve it? I have already tried updating MetaMask, restarting the extension, disconnecting and reconnecting my wallet, disabling other wallet extensions, and testing different browsers, without success. I also contacted MetaMask Support, and their system confirmed that a support ticket was created. However, I have not yet received a technical response. I am not trying to bypass any security warning. I simply want to understand what caused this sudden problem and how to resolve it safely. I would really appreciate your technical guidance. Thank you very much for your assistance! ---

I think the issue might be with the token or the smart contract you’re trying to swap. I’ve seen this warning before when I tried testing a scam token. When I got to the signing stage, the confirmation button disappeared, and I couldn’t sign the transaction. I strongly recommend not ignoring this warning. It’s better to contact MetaMask Support and share more details with them so they can check which contract you’re interacting with, what permissions the transaction is requesting, and which liquidity pool your funds will be sent to. > **[MetaMask Help Center](https://support.metamask.io/)** > > MetaMask only offers customer service through this Help Center and our community forums. ---

Hello Oxsoltani, Thank you for your warning and your advice. I understand the importance of not ignoring MetaMask security alerts. I am depositing USDC into Aave V3 on the Base network through Jumper Earn, receiving aBasUSDC. I have successfully completed similar deposits and withdrawals many times before. I also tested two different exchange providers, Nordstern Finance and SushiSwap Aggregator, with different transaction amounts, including just 5 USDC. However, the same red “Review alert” button appears in every test and is completely unresponsive. Could you please help me identify whether the warning is related to the LI FI Diamond contract, the Aave deposit token, the requested permissions, or a malfunction in MetaMask’s security alert interface? I would like MetaMask to review the exact contract and transaction details before I sign anything. I have already opened a support ticket but have not yet received a technical response. Thank you for your assistance! ---

yes . I think MetaMask security system checks the contract, liquidity, token holders, and possibly a few other things before a transaction is signed. I’m not entirely sure exactly what it checks or how it all works, though. But These warnings are based on the token contract and the info MetaMask has available at the time. For example, a contract might have been working fine an hour ago, but the developer could make changes to it afterwards. Since these checks can be updated at any time, the warnings might also change and could look different for different users. It’s best to wait for a response from MetaMask Support and avoid interacting with this contract for now. Thank you 🙂
