CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built for scale and compliance.
- End-to-End Development: From initial design and
Solidity 0.8+coding to deployment and verification onEVMchains. - Security & Audits: Rigorous internal testing, formal verification, and coordination with top-tier audit firms.
- Gas Optimization: Code-level analysis to reduce transaction costs by 15-40% for your users.
- Compliance Ready: Integration patterns for
ERC-20,ERC-721, and other standards with upgradeability via proxies.
We deliver audited, production-grade contracts in as little as 2-4 weeks, enabling faster time-to-market without compromising on security.

ARCHITECTURE
Core Components of Our Versioning System
Our Cairo staking contract versioning framework is built on four foundational pillars, designed to give your team the confidence to deploy upgrades without compromising security or user funds.
01
Immutable Proxy Architecture
We implement a transparent proxy pattern where user funds are held in a permanent, immutable vault contract. Upgrade logic resides in separate, versioned implementation contracts, ensuring the core asset storage can never be altered or compromised.

Fund Vault
02
Deterministic Upgrade Paths
Every contract version upgrade follows a strict, on-chain governance process. We codify upgrade proposals, timelocks, and multi-signature approvals directly into the system, providing full audit trails and eliminating unilateral changes.

03
State Migration Automation
Our system includes automated scripts and Cairo libraries for seamless state migration between versions. This eliminates manual data handling errors and reduces upgrade downtime from days to hours, with zero data loss.

Comprehensive Version Rollback
Built-in emergency shutdown and rollback mechanisms allow you to revert to a previous, verified contract version within a single block if a critical bug is detected, protecting user assets and maintaining protocol integrity.

SECURITY & COMPLIANCE
Why Managed Versioning is Critical for Staking
Unmanaged smart contract upgrades are a leading cause of protocol exploits and user fund loss. Our managed Cairo staking versioning service delivers secure, predictable, and compliant contract evolution.
01
Zero-Downtime Upgrades
We implement proven upgrade patterns (like Proxies & Diamond Standard) to deploy new contract logic without interrupting user staking or rewards. Eliminate migration chaos and maintain 100% service continuity.

Security-First Deployment Pipeline
Every version undergoes mandatory audits, formal verification, and testnet staging before mainnet deployment. We integrate with security partners and maintain a verifiable audit trail for every change.

StarkNet Staking Versioning FAQs
Get clear, expert answers to the most common questions about upgrading and managing your staking protocol on StarkNet.
A standard versioning project with a single major upgrade takes 3-5 weeks from audit analysis to mainnet deployment. This includes 1-2 weeks for code review and upgrade path design, 1-2 weeks for development and internal testing, and 1 week for final client testing and deployment. Complex migrations with multiple contracts or significant logic changes may extend to 6-8 weeks.
