Improved security UX in web3 is an important part of providing end-users a stress-free crypto experience. Blowfish’s scam list, which we use for Verify API, is a big step in that direction. Blowfish’s message and transaction simulation APIs offer awesome ways for wallets to provide a good signing UX. I look forward to the day when all wallets use transaction and message simulation!
