A few months back we asked the Farcaster community for feedback on the Superchain interop docs. People had great feedback to share and were curious about how the Superchain interop cluster was governed, cross-chain tx safety, and overall architecture. We took the feedback and with the help of OP Stack / http://ethereum.org contributor Ori, we refactored the Superchain interop docs. Please take a look and let us know what questions you have and how we can improve it :) Note the tutorials are still being overhauled but will be ready to go ahead of ETHDenver

Did you know you can deploy SuperchainERC20 tokens today? https://console.optimism.io/build If you've used the SuperchainERC20 starter kit I'd love to chat to learn how we can improve it!

We asked for feedback on OP docs a few weeks back and one of the most common themes that came up was confusion around transaction finality and a successful fault proof challenge causing a chain reorg We've recently published this explainer on tx finality to debunk some of these common misconceptions: https://docs.optimism.io/stack/transactions/transaction-finality Take a peak and let us know what you think - I'm optimistic even if you're an OP Stack subject matter expert you might learn a thing or two from this explainer :)

Started using /definitive last weekend and wishing I started using it earlier Only things keeping it from being a 10/10 recommend: - Overhauled auth (changing between evm vs solana is painful) - Chain abstracted balance for USDC on Solana / Base (have to use a 3rd party app to rebalance inventory) - Mobile support Limit orders, TWAP, and seeing cost basis though 😮‍💨

wtf is ERC-7802? Every token should have a cross chain strategy. ERC-7802 introduces a minimal interface for tokens to communicate cross-chain that can be used across all Ethereum scaling solutions. It’s a simple lego block to help unify Ethereum. Let’s get rid of bespoke interfaces per ecosystem that slow down the Ethereum developer experience. Use one interface to move assets across these solutions. Join the discussion on ERC-7802 here: https://ethereum-magicians.org/t/erc-7802-crosschain-token-interface/21508

Request for comment on interoperable ETH on the Superchain! We have a design choice around interoperable ETH and wanted to get your feedback on some of the choices. The design doc is here: https://github.com/ethereum-optimism/design-docs/pull/146/files

Coinbase reported 8M monthly transacting users (MTU) in their Q2 2024 earnings. Base has ~23M MTU (h/t GrowThePie). Yes a verified user != a transacting address, and yes a verified user doesn't monetize the same way as a transacting address. But the key insight here is, by going onchain, Base is helping Coinbase reach an audience it wasn't able to reach before, either due to regulatory or operational reasons. This playbook can be applied to any corporation looking to expand the reach of their product.

Any asset, any event can be used with Superchain interop. Yes that means maximally capital efficent, 1 block latency asset transfers. But that’s just the beginning. What will you build? Use Supersim TODAY to prototype whats possible and get ready for the interop upgrade

Cash App is only available in the US and UK. It targets households earning <$150K. In Q2 Cash App did 4B in revenue. Monetization rate was up 9 bps YOY due to Cash App borrow. Users are effectively paying 65% APR for these loans. Compare that to the borrow rate of your favorite lend/borrow protocol. "...on average, a Borrow loan is less than $100 and one month in duration, which is much smaller and shorter-term than what a typical bank can offer...has resonated well with our customer base, with more than $2 billion in originations in the second quarter, up nearly 3x year over year." These are undercollaterized loans but can't help but think crypto rails would enable Cash App to reach a global audience AND drive these borrow rates down for consumers.

I saw some discussion re Wallet homepage reverting to just assets. I personally love not having my assets on my homescreen and getting hit the a myriad of red / green signals. Would love for my Coinbase Wallet homepage to be something like my Base name profile or /talent profile. eg whats my activity and what are my friends doing onchain lately? cc @jessepollak

A few months ago members of the Optimism Collective had a running competition. 25 USDC buy-in, winning team decides where tokens are donated to. Agora absolutely smoked the competition (so much so that we didn’t even tally up the final numbers 😂) We just executed the transfer of USDC to the Protocol Guild! https://optimistic.etherscan.io/tx/0x179356c768ec831a8af2bf7417923442513b1673496a2a05a718be517d5d4629 h/t @yitong for helping facilitate this first (of many!) competitions
