MetaMask Warning Fix Guide
MetaMask's "This is a deceptive request" warning is one of the most common blocklist issues faced by legitimate dApps. When users see this red banner, most immediately close the tab, devastating your conversion rates.
MetaMask uses multiple security providers including Blockaid and community-maintained phishing lists. While these protect millions of users from scams, they also generate false positives that can destroy legitimate projects overnight.
MetaMask's primary security provider uses AI that sometimes misclassifies new or unusual smart contract interactions
Open-source blocklists like eth-phishing-detect can be updated by anyone, leading to false reports
Having a domain name similar to known scam sites triggers pre-emptive blocking
New projects with sudden popularity spikes often get flagged as potential rug pulls
Complex smart contracts with unusual patterns can trigger security warnings
MetaMask uses multiple providers - you need to know which one flagged you to file the right appeal
Compile proof of legitimacy including business registration, audit reports, and user testimonials
File separate appeals with each provider that has flagged your domain - this can include Blockaid and community lists
Track your appeals and be ready to provide additional information if requested
MetaMask primarily uses Blockaid for transaction security and references multiple community phishing lists including eth-phishing-detect. Each provider has its own appeal process.
MetaMask checks domains against blocklists as soon as the page loads, not just during wallet connection. This means users see warnings immediately upon visiting your site.
No, MetaMask's security features are built into the wallet itself, not the RPC endpoint. The only solution is to get removed from their blocklists.
Not necessarily. Most wallet warnings are false positives caused by overly aggressive automated detection systems. However, it's always good practice to run a security audit to ensure your site hasn't been compromised.
Studies show that security warnings reduce conversion rates by 85-95%. For a typical DeFi project, this can mean thousands of dollars in lost revenue per day. The sooner you resolve the warning, the less impact on your business.
This is not recommended. Users have been trained to trust wallet security warnings, and asking them to bypass these protections will damage your credibility and could be seen as a red flag itself.
