[AUDIT] OP Stack Operators Guide FAQ

[cpengilly]

• What can OP Chains do or configure that wouldn’t break homogeneity?

• Their specific ask is for CSR, but in general they’re asking for more clarity on what would / wouldn’t break compatibility

• this question keeps coming up for multiple teams

• right now anything that's execution (geth changes) and settlement (bridging, deriving, 7-day withdrawal) breaks compatibility

• Where do OP Chains need to update info in OP Stack repo (eg. token list)

• Base told them there are a “dozen places” that Base had to update and they’re trying to find out what all those places are

• this might be an eng question but feels like low hanging fruit to have a list to share with OP Chains

• devX has a project that seeks to automate this! we'll start by compiling a list first, but on our minds

• Super rough list: chainlist, ethers/viem, OP SDK, wallets (Metamask especially), various configs (superchain-registry to start)

• Can we have some kind of bridge shared liquidity pool for OP Chains?

• They are talking to teams like Hop but need to front liquidity. If there were a shared liquidity pool, it would reduce costs for fronting the liquidity

• They are excited about LayerSwap bc they jumped on building out L2 to L2 bridging

• The solution here is likely not exactly what people are thinking of. We'd want to be careful with the design and how we pay for that liquidity!

• Stablecoin availability?

• current thinking around this: either we create L2 to L2 messaging and they integrate with 1 hub chain (e.g OP Mainnet)

• Or they integrate a seamless wrapped version that they own and can easily migrate once they deploy native. They said the Law of Chains is a blocker for this.

• Is CSR something that has to be breaking protocol level changes?

• devs can implement CSR out of protocol! there's a tweet around how (can find if it's helpful); this is a hackathon submission [https://ethglobal.com/showcase/shadow-rollup-k712d] implementing it in a slightly different way

• this thread on CSR that would require an L3 on PGN? https://twitter.com/kelvinfichter/status/1624975097537654786

• can reimburse periodically or “manual” reimbursement, may be cumbersome with scale

@cpengilly let's deprioritize this!
