Decentralized Sequencer Relay Networks

overview

FULL-STACK BUILD

Custom Blockchain Development

End-to-end blockchain solutions from protocol design to production deployment.

We architect and build custom blockchains, sidechains, and Layer 2 solutions tailored to your specific throughput, cost, and governance needs. Our development covers everything from consensus mechanism design to node infrastructure and network monitoring.

Protocol Design: Custom EVM-compatible chains, Substrate-based networks, and Cosmos SDK app-chains.
Core Development: Implementation of consensus (PoS, PoA), transaction pools, and RPC layers.
Infrastructure & Tooling: Validator setup, block explorers, indexers, and deployment automation.
Go-to-Market: Mainnet launch support, tokenomics consulting, and validator onboarding programs.

Deploy a production-ready, fully documented blockchain network in 8-12 weeks, backed by our team of protocol engineers.

ENTERPRISE-GRADE INFRASTRUCTURE

Core Capabilities of Our Relay Networks

Our decentralized sequencer relay networks are engineered for production-grade reliability, security, and performance. We deliver the foundational infrastructure that allows your L2/L3 to scale without compromising on decentralization or user experience.

High-Availability & Fault Tolerance

Multi-provider, geographically distributed relay nodes ensure 99.9% uptime SLA. Automatic failover and load balancing prevent single points of failure, guaranteeing transaction submission continuity even during regional outages or sequencer maintenance.

99.9%

Uptime SLA

< 50 ms

Failover Time

Gas Optimization & Cost Efficiency

Intelligent transaction bundling and gas price forecasting reduce L1 settlement costs by up to 40%. Our relays implement dynamic fee algorithms and MEV protection to ensure users get the best possible execution price for their transactions.

Up to 40%

Gas Savings

Fee Optimization

Enhanced Security & Censorship Resistance

Decentralized relay architecture eliminates centralized sequencer risks. Transactions are validated and propagated through a permissionless network of nodes, backed by cryptographic proofs and regular security audits from firms like Trail of Bits.
