    Replying to @tyneslol @Ledger and @safe
    Update: there is currently an effort to add 7702 support to both @Ledger and @Trezor. Should see some public code soon. Still need to make sure its released to end users as soon as possible

    At @Optimism we are building the future of Ethereum. Don’t get caught up in the recent alt L1 narratives, it’s still incredibly attractive to launch an OP Stack based L2. Welcome to the Superchain @Ronin_Network!

    Stripe building an L1 instead of an L2 means that they aren’t targeting existing crypto users. They don’t care about the network effect that Ethereum has today. There are a lot of people that just want something that works for their use case and won’t go outside of those rails

    Seriously concerned there will be little day one 7702 adoption. No @Ledger support yet. Does anybody know apps targeting day one support? I'd like to upgrade EOAs into @safe smart contract wallets

    If we get support in the app that runs on the device itself, then we can start getting support in the wallet frontends that are widely used Looks like there is an open issue here: github.com/LedgerHQ/app-e…

    At EthDenver, the @optimismPBC team implemented EIP 1153 - transient storage opcodes! This EIP dates back to 2018, and was recently brought back into interest by @sendmoodz due to its usefulness for smart contract developers

    Extremely simple ways of communicating goals enables coordination to scale. When Solana says "increase bandwidth, reduce latency" it aligns the community while creating space for individuals to figure out the details required to make it happen. One could fearmonger and say that

    Based rollups. Why would you want to delegate the liveness of your app to unaccountable third parties and expose your users to the MEV supply chain? Own the end to end experience without compromising on the property rights of users, censorship resistance and ability to exit

    The easiest way to build a stage 2 rollup is to not have a canonical bridge. Over the coming years, we will learn what the real product requirements are and what the cargo cult ideas are. There is a push to have L1 be the canonical asset hub with low latency asset portability

    Ethereum needs single slot finality and faster block times for L2s to be truly competitive with Malachite chains
