FULL-STACK INFRASTRUCTURE
Custom Blockchain Development
End-to-end blockchain solutions from protocol design to production deployment.
Deploy a custom, high-performance blockchain in 4-8 weeks with a dedicated engineering team.
Our development process is built for founders:
- Rapid MVP Delivery: Go from concept to testnet in 2-4 weeks.
- Modular Architecture: Use proven modules for consensus (
Tendermint,Substrate), EVM compatibility, and token standards (ERC-20,ERC-721). - Security-First: All code undergoes formal verification and third-party audits before mainnet launch.
We specialize in bespoke chains for specific use cases:
- App-Specific Chains (AppChains): Isolated execution for DeFi protocols and gaming platforms.
- Enterprise Consortium Networks: Permissioned networks with custom governance for B2B applications.
- Layer 2 & Rollups:
