overview
CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built for scale and compliance.
- End-to-End Development: From initial design and
OpenZeppelinintegration to deployment and verification onEVM/Solana/Cosmoschains. - Security as Standard: Every contract undergoes automated analysis and manual review against the latest attack vectors before deployment.
- Gas Optimization: We write for efficiency, delivering contracts with up to 40% lower gas costs for end-users.
- Compliance Ready: Built-in support for pausable functions, upgradeable patterns, and access control to meet regulatory requirements.
We don't just write code; we deliver a secure, auditable, and maintainable asset that powers your business logic on-chain.

Business Outcomes: Beyond Bug Finding
Our Formal Verification SDK delivers more than just security. It's an engineering multiplier that accelerates development, builds investor confidence, and protects your protocol's long-term value.
01
Accelerated Time-to-Market
Automated property verification reduces manual audit cycles by 40-60%. Ship production-ready L2 primitives (bridges, sequencers, DEXs) in weeks, not months, with mathematically proven correctness.

A Technical Comparison for L2 Development Teams
Formal Verification vs. Traditional Security Methods
Understanding the fundamental differences in security assurance for your Layer 2 rollup or appchain.
| Security Aspect | Traditional Audits | Formal Verification (Chainscore SDK) |
|---|---|---|
Guarantee Type | Probabilistic (expert opinion) | Deterministic (mathematical proof) |
Coverage Scope | Sampled code paths & manual review | Exhaustive analysis of all possible states |
Time to Result | 2-4 weeks per audit cycle | Continuous verification in CI/CD pipeline |
Cost Model | Project-based ($50K-$500K+) | Subscription-based SDK license |
Bug Detection | Known vulnerability patterns | Formal specification violations |
False Positives | High (requires manual triage) | Near-zero (logic-based proofs) |
Maintenance Burden | Re-audit required for every update | Proofs automatically re-verified on change |
Integration | External, post-development phase | Integrated development workflow |
Team Skill Required | External auditor expertise | Developer-friendly API & tooling |
Long-Term Assurance | Snapshot in time | Continuous, provable correctness |

PROVEN METHODOLOGY
Our Delivery Process: From Specification to Proof
Our structured, four-phase engagement delivers mathematically verified smart contracts for your L2, reducing security risk and accelerating your time-to-market.
01
Phase 1: Formal Specification
We translate your protocol's business logic and security invariants into a machine-readable formal specification using TLA+ or Coq. This creates the single source of truth for verification, eliminating ambiguity in requirements.

Phase 2: Model Implementation
Our engineers implement a high-fidelity model of your smart contract system based on the formal spec. This abstract model is exhaustively tested for property violations before a single line of Solidity/Vyper is written.

Technical & Commercial FAQs
Formal Verification for L2s: Common Questions
Get clear answers on our formal verification process, timelines, and security guarantees for Layer 2 protocols.
A full formal verification audit for a standard L2 bridge or sequencer contract typically takes 2-4 weeks from kickoff to final report. This includes specification development, modeling, verification, and remediation support. Complex protocols with custom opcodes or novel consensus mechanisms may require 6-8 weeks. We provide a detailed project plan within the first 3 business days.
