INFRASTRUCTURE
Blockchain API Development
Production-ready APIs to integrate blockchain data and transactions into any application.
- Multi-Chain Data Feeds: Unified endpoints for balances, token prices, NFT metadata, and transaction history.
- Transaction Relayers: Gas-optimized broadcast services with nonce management and fee estimation.
- Webhook & Event Systems: Instant notifications for on-chain events like transfers, swaps, or contract interactions.
- Custom Indexing: Tailored data aggregation for complex DeFi positions or gaming leaderboards.
Deploy a fully managed, enterprise-grade API layer in under 2 weeks, eliminating the need for in-house RPC node maintenance and data indexing pipelines.

PREDICTABLE, PROVEN PATH
Our Delivery Process: From Template to Live Chain
We provide a structured, four-phase framework to transform a template into a production-ready sovereign chain, ensuring technical excellence and predictable timelines.
01
Phase 1: Template Selection & Scoping
We guide you through our library of battle-tested templates (e.g., L2 rollup, appchain, DeFi hub) to select the optimal foundation. We then define custom parameters, tokenomics, and governance models to align with your specific use case.

Phase 2: Custom Development & Integration
Our engineers implement your custom logic, integrate required modules (bridges, oracles, RPC), and configure the chain's consensus, data availability, and execution environment. We follow security-first development practices using OpenZeppelin libraries and established patterns.

Phase 3: Security Audit & Testnet Deployment
Your chain undergoes rigorous internal testing and a formal security audit by our partners or your chosen firm. We deploy to a dedicated testnet, enabling stress testing, validator onboarding, and final adjustments before mainnet launch.

Frequently Asked Questions for Sovereign Chain Teams
Get clear answers on how our battle-tested contract templates accelerate your sovereign chain's time-to-market while ensuring security and best practices.
With our pre-audited templates and deployment automation, teams can launch a fully functional sovereign chain with core DeFi primitives (DEX, staking, governance) in 2-4 weeks. This timeline includes custom parameter configuration, initial testing, and mainnet deployment support. For chains requiring extensive custom logic, the timeline extends based on complexity.
