Security fix disclosure: PropAMM contract We fixed a critical bug in the PropAMM contract in main branch; our factories on Ethereum mainnet are not affected by this vulnerability. The vulnerability found was due to the PropAMM contract that had a leftover setup function, reinitializeV2, which anyone could call once on a newly created PropAMM. Calling it could let an exploiter point the PropAMM at a price feed they control and then trade against its vaults at any price they chose, emptying them. More information here: From our conversations with third parties interested in it and from the information we have seen on-chain, there should not be anyone affected. But if anyone has deployed their own factory, or their own PropAMM forking our code, from this repo's code before October 27, 2026, please follow the instructions below: revoke your vaults' approvals to the PropAMM or move the funds out of the vaults create a new PropAMM through our mainnet factory (address in docs/production.md) or from the latest main.

Great meeting with @serenita_luca! @SerenitaIO was one of ethrex's early adopters, and we enjoyed hearing more about the team's work on Vero. Excited to keep working together to bring more client diversity to Ethereum with @ethrex_client and @ethlambda_lean.

Miden mainnet is live with its first partners. We've been building the Rust and web SDKs and contributing across the stack, including the protocol and node. Practical privacy now has a live network. Access opens up from here.

At LambdaClass we're pushing Ethereum to become the world's financial hub, and we think PropAMMs are key to getting there. So far, $546M+ has traded across 68k+ swaps, and on the major pairs (BTC, ETH, and stables) PropAMMs are quoting tighter than Binance and major DEX venues on several. So we built open-source tools to make them effortless to integrate and access: an SDK and an onchain Router. Huge thanks to @titanbuilderxyz for pushing PropAMM adoption 🙏
