Scaling Ethereum isn’t just about speed. The real goal is to deliver meaningful value to users. Swellchain is a Layer 2 network designed with this purpose, enabling users to make better use of their assets and increase the impact of restaked assets.

Swellchain features a Proof of Restake (PoR) model that encourages a cycle of growth: as more activity occurs, rewards for restakers and infrastructure providers increase. This attracts additional participation, deepens liquidity, and supports greater decentralization, aligning Swellchain closely with Ethereum’s broader vision.

Swellchain addresses three primary challenges common to current Layer 2s: limited liquidity, centralized control, and lack of native yield. By adopting PoR, Swellchain lets users restake liquid assets to secure the network and earn rewards tied directly to on-chain activity.

Secure Block Building (SBB) enables rollups to access MEV (Maximal Extractable Value) as a stable and transparent revenue stream. Rather than relying on harmful practices, such as frontrunning (where transaction orders is manipulated for profit), SBB uses backrunning approach. Here, arbitrage trades are are are executed after user transactions, ensuring revenue benefits the rollup and its stakeholders.

For Swellchain, SBB enhances the PoR model by transforming MEV from a challenge into a catalyst for growth:

• Consistent and sustainable MEV revenue through backrunning

• Protection against negative MEV behaviors like frontrunning

• Reliable income to support long-term expansion

• Stronger PoR cycle, increasing rewards, security, and user participation

Swellchain is built on the OP Stack and is part of the Superchain, a network of rollups working to scale Ethereum together. SBB is built with Flashbot’s Rollup-Boost, making it natively compatible with the OP Stack. This means any OP Stack-based rollups can integrate SBB from the outset, enabling backrunning revenue as native features.

Key benefits of SBB for the Superchain include:

• Protocol-native integration for OP Stack rollups

• New opportunities for realizing MEV revenue

• Stronger foundations for the growth of Superchains

Swellchain is one of the first rollups in Alpha Engine, a modular platform bringing together MEV revenue (Radius), shared security (Symbiotic), and cross-rollup interoperability (Avail). Participation in Alpha Engine allows Swellchain to concentrate on its core strengths while leveraging broader infrastructure for more efficient and secure scaling.

Secure Block Building helps rollups like Swellchain capture MEV sustainably, setting the stage for a more connected, value-aligned economy. Our upcoming Lighthouse will connect L2s, Ethereum L1, and centralized exchanges through shared MEV markets, bringing us closer to true economic interoperability where value flows seamlessly across the ecosystem.
