INFRASTRUCTURE
Blockchain API Development
Custom, high-performance APIs to connect your application to any blockchain network.
- Multi-Chain Support: Unified or dedicated APIs for
EVMchains (Ethereum, Polygon, Arbitrum),Solana, andCosmos SDK. - Developer-First Design: Full-featured REST & WebSocket endpoints with comprehensive documentation and
Postmancollections. - Enterprise Reliability: Built-in rate limiting, automatic failover, and detailed analytics dashboards.
- Custom Logic: Embed complex on-chain logic—like token gating or multi-sig verification—into simple API calls.
Deploy a production-ready, fully documented API layer in under 3 weeks, eliminating months of internal RPC node management and indexer development.

Frequently Asked Questions
Get clear, technical answers on how we build secure, scalable bridges for NFT-backed loans.
A complete, audited MVP for a cross-chain NFT lending bridge typically takes 6-10 weeks. This includes protocol design, smart contract development on both source and destination chains (e.g., Ethereum and Solana), bridge relayer infrastructure, and a basic front-end dashboard. Complex features like multi-chain support or custom liquidation engines can extend the timeline, which we scope and quote for upfront.
