MetaMask Faces External Server Connection Errors Despite Privacy Settings

A connection error to Bitcoin network and price information servers has been discovered in the virtual asset wallet MetaMask, even though users have disabled external service usage features for privacy protection. The MetaMask development team has begun modifying the code to resolve this issue. According to the code modification released on GitHub by MetaMask on the 12th, it was confirmed that even when users disable the 'Basic Functionality', there are still issues connecting to some external servers. The basic functionality allows MetaMask to connect to external servers to retrieve information such as digital asset prices or wallet balances. However, in the existing MetaMask, it was found that even if users turned off the feature, some programs that were already running continued to communicate with external servers. The problem arose from an additional feature of MetaMask called 'Snaps'. Snaps is a program that helps users access various blockchain services such as Bitcoin or Stellar within MetaMask. Previously, when users turned off the basic functionality, new Snap requests were blocked, but already running Snaps continued to operate. This resulted in maintaining connections with some external servers. The MetaMask development team has modified the code so that when users turn off the basic functionality, running Snaps will also be stopped and connections to related external servers will be terminated. After reproducing the error and conducting internal tests, the development team found that the issue occurred in all four instances before the modification, but after the modification, all four instances operated normally. Earlier, on October 29, MetaMask had also disclosed an issue where requests were sent to multiple external servers while the basic functionality was turned off. However, it has not been confirmed whether this modification resolves all the errors that occurred at that time.
