Building Toward a More Verifiable Rollup

On July 24th, the Superseed network was upgraded to the latest Optimism contracts as part of our ongoing work to support fault proofs and lay the groundwork to become a Stage 1 rollup.

There was no downtime and no disruption to users. But it marked a meaningful step forward.

What’s Changing

  • We upgraded to Optimism contracts/v3.0.0, the current tagged release of the protocol’s smart contracts. This version is officially supported for OP Stack deployments. You can view the deployed contracts for Superseed here.

  • We activated the Fault Proof Module in permissioned mode, which allows fraud proofs to be submitted by an allowlisted address.

  • The Superseed network now supports an operator fee, offering more flexibility for future upgrades and long-term sustainability.

  • If a withdrawal was in progress at the time of the upgrade, it will be re-proven under the new contracts. This will be handled internally. There’s nothing you need to do.

Why This Matters

Ethereum’s long-term vision depends on rollups. Vitalik and others have made it clear that what matters most isn’t decentralization for its own sake, but building systems that are verifiable, secure, and credibly neutral over time.

This upgrade moves us in that direction — toward permissioned fault proofs and eventually, permissionless ones too. We're not there yet, but the foundations matter.

L2BEAT classifies rollups by how verifiable and secure they are, broken down into three stages:

  • Stage 0 – A live proof system (even if permissioned) and a canonical Ethereum bridge

  • Stage 1 – A proof system with a Security Council or committee that can submit or challenge proofs

  • Stage 2 – Permissionless proofs and no upgrade keys — the system is verifiable, immutable, and credibly neutral

This upgrade brings Superseed into Stage 0 by activating a live fault proof system and maintaining state commitments through a canonical Ethereum bridge.

It also moves us closer to Stage 1, where a designated Security Council will be able to submit fraud proofs. That structure improves the trust model and helps align us with Ethereum’s roadmap.

What’s Next

To reach Stage 1, we’ll need to:

  • Finalize a trusted Security Council to operate permissioned fraud proofs

  • Ensure that at least 75% of members would need to collude to block or forge a withdrawal, in line with L2BEAT’s updated requirements

  • Expand infrastructure for monitoring and proving state transitions

  • Continue building toward a fully open, permissionless fraud proof system

We're working through these questions now with Optimism, Conduit, and other infrastructure partners. The path to Stage 1 is becoming clearer, and we’re designing it with Ethereum’s values in mind.

The Bigger Picture

Superseed is designed to repay your debt through network activity. That only becomes meaningful if the chain itself moves toward verifiability and structures that reduce reliance on any one party over time.

This upgrade lays the foundation for a more credible system. One step at a time.

Thanks for being here.

Welcome to a future where your chain repays you, and proves it.
