FULL-STACK INFRASTRUCTURE
Custom Blockchain Development
End-to-end blockchain infrastructure tailored to your specific business logic and performance requirements.
- Layer 1 & 2 Development: Build purpose-built chains on
Substrate,Cosmos SDK, or as anEVML2 rollup. - Smart Contract Suite: Core logic in
Solidity,Rust, orGowith formal verification. - Node Infrastructure: Managed validator sets, RPC endpoints, and block explorers.
- Cross-Chain Integration: Secure bridges and messaging layers using
WormholeorAxelar.
From a 4-week PoC to a fully audited mainnet launch, we own the entire technical delivery. You get a sovereign, high-performance chain designed for your exact use case.

Frequently Asked Questions
Get clear answers on our process, security, and support for building custom payment bridges between rollups and L1.
From specification to mainnet deployment, a standard bridge project takes 3-5 weeks. This includes 1 week for architecture design, 2-3 weeks for core development and internal testing, and 1 week for client review and final deployment. Complex features like multi-asset support or custom governance can extend the timeline, which we scope and agree upon upfront.
