This morning I needed to check the signing address of my multi-signature wallet. I was using my phone, which didn't have the Safe app installed. I realized I could look up my address directly on Etherscan and then use the "Read Contract" function to get the information I needed. This kind of additional user experience advantage is possible if your wallet or app is open source and has passed security testing. Providing users with alternatives can often be very helpful in unexpected situations, more common than the Safe website simply "crashing." (Of course, this workflow will eventually have to be broken due to privacy concerns. One way to achieve an equivalent, privacy-focused workflow is for users to save a "view key," an extended version of their address containing additional private information. Block explorers could support this by placing the private information in the hash tag portion of the URL, keeping it on the client side. However, the downside of this approach is that it risks encouraging users to paste any type of secret information into URLs or web pages; ultimately, we still need to be able to perform more operations directly through the wallet.)
