overview
FULL-STACK INFRASTRUCTURE

Custom Blockchain Development

End-to-end blockchain infrastructure tailored for your application's unique performance and security requirements.

We architect and deploy custom Layer 1/Layer 2 solutions and bespoke smart contract systems that form the foundation of your product. Our development is not template-based; we build from first principles to meet your exact needs for throughput, finality, and cost.

  • Core Protocol Development: Custom consensus mechanisms (PoS, PoA), virtual machines, and node clients.
  • Smart Contract Suites: Gas-optimized, audited contracts for ERC-20, ERC-721, ERC-1155, and custom logic.
  • Integration Ready: Native bridges, oracles (Chainlink, Pyth), and wallet connectivity out-of-the-box.
  • Security-First: Development follows OpenZeppelin standards, with formal verification and audit preparation integrated.

Deliver a production-ready, mainnet-deployed blockchain core in 8-12 weeks, backed by a 99.9% uptime SLA for validator/sequencer nodes.

Technical & Commercial Details

Custom Oracle Development FAQs

Get clear, specific answers to the most common questions CTOs and technical founders ask when evaluating a custom oracle development partner.

A standard, production-ready custom oracle for EVM chains typically takes 2-4 weeks from kickoff to mainnet deployment. This includes design, development, testing, and security review. Complex integrations (e.g., cross-chain oracles, novel data aggregation) can extend to 6-8 weeks. We provide a detailed project plan with milestones during the scoping phase.
