Bitcoin Layer 2 Interoperability SDK

Development kits for building applications that interact across Bitcoin Layer 2s (e.g., Stacks, Rootstock) and the base chain, handling asset movement and state verification.
Chainscore © 2026
overview
CORE SERVICE

Smart Contract Development

Secure, production-ready smart contracts built by Web3 experts for your protocol or application.

We architect, develop, and audit custom Solidity/Rust smart contracts that form the trustless backbone of your application. Our focus is on security-first development, gas optimization, and seamless integration with your existing tech stack.

Deliver a secure, auditable, and performant on-chain foundation in weeks, not months.

  • Custom Logic: Build DeFi primitives, NFT collections, DAO governance, or bespoke business logic.
  • Security Audits: All code follows OpenZeppelin standards and undergoes internal review; we facilitate third-party audits.
  • Gas Optimization: Write efficient code to reduce user transaction costs by up to 40%.
  • Full Lifecycle Support: From design and development to deployment, verification, and ongoing maintenance.

Frequently Asked Questions

Get clear answers on how our SDK accelerates your Bitcoin L2 development, from integration to production.

For a standard integration with a single L2, deployment to testnet typically takes 2-3 weeks. Production readiness, including security audits and stress testing, adds another 1-2 weeks. Complex multi-chain or custom bridge implementations can extend to 6-8 weeks. We provide a detailed project plan after the initial technical discovery call.
