We are proud to share this small but significant step in the path towards a unified Ethereum. Stay tuned over the coming months as we release examples of higher levels of synchronous composability and the first production based L3 appchain.

Compared to traditional L3s / appchains, Spire unlocks: ✅ synchronous composability ✅ lightweight deployment ✅ customizability Developers can achieve the scalability and customization of their own appchain while accessing the liquidity and users of the underlying L2 — with the simplicity of deploying a smart contract on L2.

The demo shows a based L3 appchain synchronously reading data from its L2. This may seem simple, but the implications are significant. It previews an onchain world of millions of appchains operating in sync and secured by a single unifying network: Ethereum.

Launching an appchain is often prohibitively expensive. With Spire, however, builders can easily deploy their own L3, inheriting the composability of its underlying L2 and toolings of the Ethereum ecosystem. This means no expensive oracles, custom explorers or bespoke infrastructure. Just out-the-box deployment saving millions of dollars.

Today, we share a live public demo of the first based L3 appchain. This is a landmark moment for Spire as we demonstrate the future of Ethereum rollups: synchronous composability.

The aggregated blob is submitted to the L1 blob layer. There's now a smart contract event that rollups can listen for and be notified if an aggregated blob contains their data. When this occurs, rollups can extract their original blob and process it through their pipeline.

Our team has reached a milestone in blob aggregation! Here's an example of an aggregated blob written to the holesky network: https://holesky.etherscan.io/tx/0xc1ae48567ccf46be2bd191bfd414a7a0356d41def966b4b6ddeb4f1a19ce3602

This new model enables: ⚡ Low-latency composability ⚡ Atomic execution across appchains ⚡ Preconfirmations for reduced execution risk ⚡ A sequencer marketplace for optimal transaction processing

(2) Coordinated Sequencing: • Tx ordering is dynamically optimized for cost, latency, and execution guarantees. • Apps define custom priority rules for execution fees & failure handling. • Sequencer marketplaces let devs pick optimal execution models (MEV-aware, low-latency, etc.).

(1) Shared Settlement: • Appchains submit tx bundles to a shared sequencer instead of settling in isolation. • Transactions execute atomically within a batch — either all succeed or all revert. • Optimistic atomicity allows preconfirmations before final L2 settlement.

Spire introduces (1) Shared Settlement + (2) Coordinated Sequencing — a new execution model that enables synchronous composability across rollups. Instead of isolated appchains, Spire enables L3s to execute in a single sequencer batch.

The problem: rollup fragmentation creates liquidity islands. Each appchain operates with its own sequencer and settlement layer, leading to: 🚧 Capital inefficiency ⏳ Delayed execution 🔄 Fragmented price discovery ❌ Cross-domain execution risk

Spire is building the Based Stack to help apps launch their own based rollup L2. As ecosystems evolve, a new frontier is emerging - based L3s. This post explores how Spire’s approach can enable rollups to sync execution beyond L2s. 🧵
