CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built by Web3 veterans.
We deliver battle-tested contracts that power real-world value, not just demo code.
- Protocols & Standards:
ERC-20,ERC-721,ERC-1155,ERC-4626, and custom logic. - Security First: Built with OpenZeppelin libraries and tested against known attack vectors.
- Gas Optimization: Every line of
Solidityis optimized to reduce transaction costs by up to 40%. - Full Lifecycle: From architecture and development to deployment, verification, and monitoring.

ENTERPRISE-GRADE SECURITY
Core Capabilities of Our Move Custody Architecture
Our architecture is purpose-built for the unique security model of the Move language, delivering institutional-grade custody with the flexibility required for modern Web3 applications.
02
Modular Policy Engine
Implement granular, programmable transaction policies (multi-sig, time-locks, spending limits) directly within the Move VM. Policies are enforced on-chain, eliminating off-chain coordination risks.

Architectural Security Analysis
Move-Based vs. Traditional EVM Custody: A Security Comparison
A technical breakdown of how Move's resource-oriented programming fundamentally changes the security posture of digital asset custody compared to traditional EVM-based approaches.
| Security Dimension | Traditional EVM Custody | Move-Based Custody (Chainscore) |
|---|---|---|
Asset Encapsulation | Relies on external checks; assets are mutable data. | Native resource type; assets are non-copyable, non-droppable objects. |
Access Control Logic | Custom, error-prone modifiers and require() statements. | Built-in module-level privacy and formal ownership semantics. |
Reentrancy Risk | High; requires manual guards (Checks-Effects-Interactions). | Eliminated by the Move VM's linear type system. |
Upgrade Strategy Risk | High; proxy patterns introduce admin key centralization. | Low; immutable by default with verifiable package publishing. |
Formal Verification | Possible but complex and expensive post-audit. | Native support; Move Prover enables pre-deployment proof of invariants. |
Time to Secure Implementation | 6-12 months (design, audit, iterate). | 2-4 months (leverage inherent security primitives). |
Typical Audit Findings | 15-30+ critical/high issues per audit cycle. | 5-10+ critical/high issues, focused on business logic. |
Long-Term Maintenance Burden | High; security patches for common patterns (e.g., ERC-20). | Low; core asset safety guaranteed by the language runtime. |
