Test in Prod is not passing the quorum for rPGF😢
As a core dev building OP Stack days & nights, it's a bit discouraging. Come on.
teapawt.net/elblockchainguy/status…
Test in Prod (@testinprod_io) literally built & now maintain OP-Erigon, are an OP Stack core developer, but are only on 8 ballots right now.
IMO they are one of the clearest cases for RetroPGF.

Breaking @erc4337 infra for fun
tl;dr
- erc4337 hash function is not generating consistent userOpHash
- manipulating userOp calldata can make inconsistent userOpHash
- I developed a wallet that generates same userOpHash for any userOpHash 🤯 and quite secure(but don't use it)

Disclosing the vulnerability that could have drained funds.
tl;dr
• latest commit of EIP4337Manager can be destructed but does not risk user’s fund
• 0.4.0 @safe based 4337 wallets are in risk of losing fund
• affected wallets are safely migrated
If there's any team/protocol using gnosis based EIP4337Manager, DM.

We, Superblock, raised $7.5M last week. We will accelerate the development of a new mainnet named "Over," which provides a lightweight full node to enable anyone to run their own node. "Over" will be the most secure and stable mainnet through powerful decentralization.

If you believe in crypto long-term, consider joining a project today, put your head down, and do some actual work. Trading and shitposting are not positive sum endeavors. As a side effects, you‘ll stop measuring your self worth in net worth, making the swings much more tolerable.

No issue w/ L1s that prioritize immediate scaling over decentralization, many users want this
But this is a real bad take
Incredibly insulting to everyone working on ETH 2.0 and L2s
Especially from someone who has gained extraordinary wealth off the backs of Ethereum builders

Wild story that highlights a number of thorny issues in DeFi, while simultaneously putting the power of composability on full display.
Chatted with Curve's Charlie (is he on twitter? is he running the @CurveFinance handle?), Emergency DAO member @banteg and Mochi's @AZtztk
After @CurveFinance’s Emergency DAO deemed @MochiDeFi’s multimillion dollar Tuesday night gambit a ‘clear governance attack,’ the DeFi community is debating decentralization and fair play in the Curve Wars.

We have a proposal about removing the smart contract whitelist (e.g. a list of contracts who can lock CRV) discussed here gov.curve.fi/t/discussion-re….
Adding a twitter poll as well: should the smart contract whitelist be removed?
