GUARANTEED RESULTS
Business Outcomes for Your Rollup
Our sovereign, MEV-resistant sequencing service delivers measurable improvements to your rollup's security, economics, and developer experience. These are the concrete outcomes you can expect.
01
Eliminate MEV Extraction
We implement a fair ordering protocol that prevents front-running, sandwich attacks, and arbitrage bots from siphoning value from your users. This protects user funds and builds trust in your ecosystem.

PROVEN METHODOLOGY
Our Development & Integration Process
A structured, four-phase approach to deliver a production-ready, MEV-resistant sovereign rollup. We manage the technical complexity so you can focus on your application logic.
01
Architecture & Design
We design your rollup's core architecture, selecting the optimal data availability layer (Celestia, EigenDA, Avail) and defining the sequencer's MEV-resistance strategy (threshold encryption, fair ordering).
1-2 weeks

FULL-STACK INFRASTRUCTURE
Custom Blockchain Development
End-to-end blockchain solutions from protocol design to production deployment.
We architect and build the foundational blockchain layer for your application. Our team delivers custom sidechains, L2 rollups, and private networks tailored to your specific throughput, privacy, and consensus requirements. We ensure your infrastructure is secure, scalable, and production-ready from day one.
- Core Protocol Development: Design and implement consensus mechanisms (
PoS,PoA), tokenomics, and governance models. - Smart Contract Layer: Deploy and manage core protocol logic with
SolidityorRust, following OpenZeppelin security standards. - Node & Validator Infrastructure: Set up and maintain high-availability node clusters with 99.9% uptime SLAs and automated monitoring.
We handle the complex infrastructure so your team can focus on building the application layer and user experience.
Deliverables include: a fully documented codebase, a live testnet, a comprehensive security audit report, and a detailed deployment runbook for your engineering team.
Sovereign Rollup Sequencing
Frequently Asked Questions
Get clear answers on MEV-resistant sequencing, deployment, and our development process.
A production-ready sovereign rollup with our MEV-resistant sequencer can be deployed in 2-4 weeks for a standard implementation. This includes core infrastructure setup, sequencer integration, and initial testing. Complex customizations, such as advanced validator sets or novel consensus mechanisms, may extend the timeline to 6-8 weeks. We provide a detailed project plan within the first week of engagement.
