Can preconfirmations & synchronous composability make Ethereum feel like a single chain again?
Introducing another episode of Bring ETH Back: Preconfirmations & composability
📅 Oct 6, Monday
⏰ 3PM UTC
Can you be based and composable? 👀
Why this conversation now?
> Preconf research is maturing
> Validator-aligned designs are landing
> ZK proving keeps shrinking UX latency.
So, the path to instant, atomic cross-rollup UX just got real.
We’ll unpack how preconfirmations change UX:
> Commit now, finalize fast
> Fewer failed atomic transactions, fewer bridge hops
> L2↔L2 and L2↔L1 flows in a single user motion
The guests are bringing the signal. 👇
. @MuratLite, Founder & CEO at @primev
Leading in preconf + sequencing design
He’s spoken about leader-based preconf designs and how builders or proposers can commit promises to users ahead of finality.
We’ll dig into: when leaders vs leaderless preconfs make sense, and how these commitments change UX in practice.
. @lepsoe, Founder at ETHGas
Cross-domain / interop architect, leaning into standards like RIP-7755 (ERC for cross-L2 calls) and proof systems that make cross-domain calls safer and more composable.
He’ll share insights into what it takes to build default-safe cross-rollup calls and how state proofs + messaging primitives evolve.
. @DrewVdW, Shepherd at Fabric / Commit Boost.
dApp / infrastructure thinker, he’s vocal about what builders can ship first when preconfs hit prod.
How to convert research designs into deployable UX improvements (and where tradeoffs land).
Expect a conversation around what workflows can move from async → atomic first.
What we’ll cover (builder-first):
> Synchronous composability beyond co-inclusion
> How preconfs tighten guarantees without ceding sequencer sovereignty
> AA/4337 patterns to compress multi-chain flows into one user action
> What ships now vs what needs another research lap
The goal isn’t another bridge.
It’s restoring money-lego UX across rollups,
Flash loans, arb, unified liquidity, without giving up autonomy.
