  - [The first AMM that outbids competition in real-time](https://x.com/propellerswap/status/2115072040613142567) by [PropellerHeads](https://propellerheads.xyz)

- [Glamsterdam Hard Fork: When Spent Gas Comes Back](https://www.chainsecurity.com/blog/glamsterdam-gas/?v=3) by [ChainSecurity](https://www.chainsecurity.com/) analyzes how [EIP-8037](https://eips.ethereum.org/EIPS/eip-8037) and [EIP-8038](https://eips.ethereum.org/EIPS/eip-8038) could undermine existing contract protections against insufficient-gas attacks, and proposes mitigations to preserve safe failure handling.

  - [Post](https://x.com/nero_eth/status/2114631334526161274) by [Toni Wahrstätter](https://toniwahrstaetter.com)

- [Keep the latest bid, not the highest](https://blockspace.forum/takes/keep-the-latest-bid.html) by [Blockspace Forum](https://blockspace.forum) examines bid selection under [ePBS](https://eips.ethereum.org/EIPS/eip-7732) and makes the case for proposers to use each builder’s _latest_ bid instead of its highest earlier bid, allowing builders to lower their bids as market conditions change.
