WebSocketandgRPC. - Enhanced RPC Nodes: Multi-chain support (
EVM,Solana,Cosmos) with 99.9% uptime SLA and load balancing. - Security & Compliance: Built-in rate limiting, API key management, and audit trails for enterprise security standards.
Deploy a production-ready API layer in under 2 weeks, freeing your engineers to focus on core product logic instead of infrastructure.
Architecture Designed for Payment Scale
Our sovereign rollup architecture is engineered from the ground up to meet the demanding throughput, cost, and reliability requirements of global payment systems. We deliver production-ready infrastructure, not just theoretical designs.
Horizontal Scalability
Add new sequencer nodes without downtime to linearly increase transaction throughput. Supports thousands of TPS, scaling with your user base.
Sub-Second Finality
Proprietary consensus and data availability layer ensures transaction finality in under one second, enabling real-time payment confirmation for end-users.
Cost-Optimized Execution
Custom EVM rollup client with gas optimization at the VM level, reducing transaction costs by up to 90% compared to L1 settlement.
Modular Data Availability
Flexible DA layer integration (Celestia, EigenDA, Ethereum) allowing you to balance cost, security, and throughput based on payment tier.
Managed Infrastructure & SLAs
We operate the sequencer, prover, and bridge network with 24/7 monitoring, guaranteeing uptime and performance so your team can focus on product.
Business Outcomes for FinTech Leaders
Our sovereign rollup payment systems are engineered to deliver measurable financial and operational advantages, moving beyond technical features to tangible business results.
Reduce Settlement Costs by 90%+
Move high-volume payment flows off expensive L1s. Our architecture leverages custom data availability layers and optimized proof systems to slash per-transaction fees to fractions of a cent.
Achieve Sub-Second Finality
Eliminate payment delays with a dedicated execution environment. Process thousands of transactions per second with deterministic, near-instant settlement, unlocking real-time financial products.
Maintain Full Regulatory & Operational Sovereignty
Own your chain's rules, upgrade path, and revenue. Unlike shared L2s, you control transaction ordering, fee models, and compliance logic without external dependencies.
Deploy a Production-Ready System in 8 Weeks
Accelerate time-to-market with our battle-tested rollup stack. We deliver a fully audited, mainnet-ready payment rail with custom smart contracts, RPC endpoints, and block explorer.
Guarantee 99.95% Uptime with Institutional SLAs
Meet financial-grade reliability standards. Our managed infrastructure includes multi-cloud sequencer redundancy, automated failover, and performance monitoring with contractual SLAs.
Sovereign Rollup vs. Generic Layer 2: A Strategic Choice
Key technical and operational differences between Sovereign Rollup and Generic L2 (Optimistic/ZK) architectures for payment systems, based on our deployment experience.
| Architectural Factor | Sovereign Rollup | Generic Layer 2 (Optimistic/ZK) |
|---|---|---|
Data Availability & Sovereignty | Your chain, your rules. Full control over data and sequencing. | Relies on the security and liveness of the parent L1 (e.g., Ethereum). |
Upgrade Flexibility | Seamless, permissionless upgrades. No dependency on L1 governance. | Upgrades often require complex, time-consuming governance on the L1 or via a multi-sig. |
Time to Finality | Sub-second for chain-native confirmation. Sovereign finality is immediate. | ~7 days for Optimistic fraud proofs; minutes for ZK validity proofs, plus L1 confirmation. |
Transaction Cost (Est.) | $0.0001 - $0.001 per tx. Predictable, low fees set by your validators. | $0.10 - $1.00+ per tx. Fluctuates with L1 gas prices and congestion. |
Development & Customization | Full-stack sovereignty. Custom fee models, precompiles, and VM choices (EVM, SVM, Move). | Constrained by L2 protocol design. Limited ability to modify core protocol rules. |
Security Model | Bootstrap your own validator set. Security is your responsibility to design and maintain. | Inherits economic security from the parent L1, a proven and decentralized network. |
Time to Production | 8-12 weeks for a production-ready, audited chain with a robust validator set. | 4-6 weeks to deploy and configure contracts on an existing, live L2 network. |
Ideal Use Case | High-throughput payment rails, branded chains, apps requiring unique economics or governance. | General-purpose dApps, DeFi protocols valuing maximal shared security and composability. |
Ongoing Operational Overhead | High. Requires managing validators, infrastructure, and cross-chain bridges. | Low. Infrastructure is managed by the L2 sequencer/prover network. |
Total Cost of Ownership (Year 1) | $200K - $500K+ (development, audit, validator ops, security). | $50K - $150K (primarily deployment, audit, and relay fees). |
Our Development Process: From Blueprint to Production
A structured, milestone-driven approach to deliver your sovereign rollup payment system with predictable timelines, transparent communication, and enterprise-grade security.
Architecture & Blueprint
We define your payment system's core architecture, including data availability layer (Celestia, EigenDA), settlement layer (Ethereum, Cosmos), and sequencer design. This phase establishes the technical foundation and project roadmap.
Core Development & Integration
Our engineers build the rollup node, custom VM (EVM, SVM, Cairo), and bridge contracts. We integrate your chosen DA layer, sequencer, and prover (Risc0, SP1) to create a functional, isolated testnet.
Security & Audit
Every line of code undergoes internal review followed by a formal security audit from a top-tier firm like Trail of Bits or Spearbit. We implement fixes and produce a verifiable audit report for your stakeholders.
Testnet Deployment & Staging
We deploy the rollup to a public testnet, conduct rigorous load testing, and simulate real-world payment flows. This phase validates performance, fee economics, and cross-chain interoperability.
Mainnet Launch & Sequencer Handoff
We manage the mainnet deployment, configure validators, and launch the production sequencer. We provide comprehensive documentation and operational training for your team to assume control.
Post-Launch Support & Scaling
We offer ongoing infrastructure monitoring, performance optimization, and upgrade planning. Our team supports you through scaling challenges, protocol upgrades, and new feature integration.
Technical and Strategic Questions
Common questions from CTOs and technical founders evaluating our architecture services.
Our standard engagement follows a 4-phase process: Discovery & Design (1 week), Core Development & Integration (2-3 weeks), Security Audit & Testing (1 week), and Production Deployment & Handoff (1 week). Most sovereign rollup payment systems are live in 4-6 weeks. We provide a detailed project plan with weekly milestones upon kickoff.
