Plain Wallet: Ethereum & EVM

Plain Wallet is a very minimal, open-source wallet for Ethereum and other EVM networks. On iPhone it's a browser with the wallet built in: type a site's address and the site gets Plain Wallet as its wallet. On a Mac it's a Safari extension plus the same wallet in a window of its own. Ethereum, Base, Arbitrum, Optimism, Polygon, BNB Chain, Avalanche and Gnosis are built in, and you can add any other EVM network. You can send the gas token or any ERC-20 token, see your balances and the sites you've connected, and on iPhone star the sites you use so they stay on top of the wallet's home screen. Every connection, signature, transaction and network change waits for your approval, which shows the site, the network, the account, and for a transaction the recipient, the amount and the maximum fee. Token approvals and transfers are spelled out in a sentence with unlimited amounts flagged, signatures that could hand over your assets are flagged too, and each transaction is simulated first, so you see your balance changes or the reason it would fail before you sign. Keep a cold wallet as a watch-only account: use it with balances, sending and sites as usual, and sign each request in Plain Wallet on another device that holds the key, even one that stays offline. You can create a new seed phrase, import one or a private key, and give your accounts nicknames. Your seed phrases and keys are encrypted with your password and stay on your device, and Plain Wallet never sends them to any server. The wallet locks after 15 minutes without use. On iPhone it also locks after a minute away from the app, and you can unlock it with Face ID or Touch ID if you like. Plain Wallet has no servers, accounts, ads, analytics or tracking, and its developer receives no data from it. It's about 2,850 lines of TypeScript with three runtime dependencies, open source under the MIT license at https://git.borodutch.com/backmeupplz/plainwallet. It hasn't been audited, so please don't keep funds in it that you can't afford to lose.
