We architect and deploy custom smart contracts that form the operational backbone of your Web3 product. Our development process is built on security-first principles, utilizing audited libraries like OpenZeppelin and rigorous internal testing to mitigate risks before mainnet deployment.
Miniscript Policy Compilation & Audit
Smart Contract Development
Secure, production-ready smart contracts built for scale and compliance.
- Token Systems: Custom
ERC-20,ERC-721, andERC-1155contracts with advanced features like vesting, minting controls, and governance hooks. - DeFi & DEX Logic: Automated Market Makers (AMMs), liquidity pools, staking mechanisms, and yield aggregators with gas-optimized math.
- Enterprise Modules: Multi-signature wallets, access control systems, and upgradeable proxy patterns for future-proofing.
We deliver fully documented, auditable code with a clear path from testnet to mainnet, ensuring your core logic is both powerful and secure.
Core Capabilities
Our Miniscript policy compilation and audit service delivers production-ready, secure Bitcoin smart contracts. We translate complex business logic into optimized, verifiable code, accelerating your time-to-market.
Policy Design & Architecture
We architect robust spending policies for complex multi-signature wallets, timelocks, and vaults. Our designs ensure your security model is correctly encoded in Miniscript from the start.
Compilation to Miniscript
Conversion of your high-level security requirements into optimized, human-readable Miniscript. We ensure the compiled policy is minimal, efficient, and compatible with major Bitcoin libraries.
Formal Verification & Audit
Rigorous analysis using static analysis tools and formal methods to verify correctness. We identify logical flaws, potential fee inefficiencies, and security vulnerabilities before deployment.
Descriptor & Address Derivation
Generation of standardized output descriptors (e.g., wsh()) for seamless integration with wallets and services like Bitcoin Core, BDK, and Specter. We provide full derivation paths.
Performance & Fee Optimization
Expert tuning of Miniscript policies to minimize on-chain footprint and transaction costs. We optimize for witness size and script satisfaction complexity.
Integration Support & Documentation
Comprehensive technical documentation and integration guides for your engineering team. We provide clear examples for policy satisfaction and signing flows.
Business Outcomes
Our Miniscript policy compilation and audit service delivers verifiable security and operational efficiency for your Bitcoin-based products. We focus on measurable results that reduce risk and accelerate development.
Optimized On-Chain Footprint
We deliver scripts with minimized witness size and transaction weight, directly reducing your users' transaction fees. Our compilation targets the most cost-efficient Taproot script path.
Accelerated Time-to-Market
From policy design to audited, production-ready script in under 10 business days. Our standardized process and deep protocol expertise eliminate weeks of trial and error for your team.
Ongoing Security Assurance
Post-audit, we provide a 90-day warranty covering any critical vulnerability discovered in the delivered artifacts, along with consultation on script spending and condition updates.
Build vs. Partner with Chainscore
Compare the cost, risk, and time investment of developing a secure Bitcoin policy system in-house versus partnering with our specialized team.
| Factor | Build In-House | Partner with Chainscore |
|---|---|---|
Time to First Secure Policy | 4-6 months | 2-4 weeks |
Security Audit Requirement | High (External audit required) | Included (Certified audit report) |
Miniscript Expertise Required | Senior Bitcoin Dev (Rare skill) | Provided by our team |
Ongoing Policy Maintenance | Your engineering team | Optional SLA with 24/7 support |
Total First-Year Cost | $150K - $300K+ | $25K - $75K |
Guaranteed Uptime & Support | None (Self-managed) | 99.9% SLA with 4h response |
Integration Complexity | High (Custom wallet/backend) | Managed API & SDK |
Risk of Protocol Changes | Your team must monitor & adapt | We handle updates & migrations |
Our Delivery Process
A systematic, expert-led workflow designed for security-first Bitcoin development. We deliver auditable, production-ready Miniscript policies with clear deliverables at every stage.
Discovery & Policy Design
We analyze your multi-signature, timelock, or complex spending logic requirements. Our experts translate your security model into an optimal, human-readable Miniscript policy blueprint.
Compilation & Optimization
Using industry-standard tools like bdk and rust-miniscript, we compile your policy into a Bitcoin Script descriptor. We optimize for script size, execution cost, and privacy (e.g., Taproot).
Security Audit & Formal Verification
Every compiled script undergoes rigorous analysis. We verify correctness (no malleability), simulate attack vectors, and formally prove the script enforces your intended policy.
Documentation & Handoff
Receive comprehensive technical documentation, including the policy tree, threat model, recovery procedures, and a clear audit report. We ensure your team can own and operate the solution.
Frequently Asked Questions
Get clear answers on our specialized service for building and securing Bitcoin-based smart contracts.
Our standard engagement for a single policy compilation with a comprehensive security audit takes 2-3 weeks. This includes policy design, iterative compilation to optimal script, and a full security review. Complex multi-party vaults or novel covenant designs may extend to 4-5 weeks. We provide a detailed project plan with milestones after the initial scoping call.
