Secure, production-ready smart contracts built for scale and compliance.
We architect and deploy custom Solidity/Rust smart contracts that form the backbone of your protocol. Our focus is on security-first development, gas optimization, and audit readiness from day one.
Deliver a battle-tested foundation that handles real volume and value.
OpenZeppelin standards and formal verification where required.We manage the full lifecycle: from initial specification and development to deployment on Ethereum, Polygon, Solana, or other L1/L2 networks, and ongoing maintenance. Typical delivery for a core MVP contract suite is 3-4 weeks.
Our specialized tooling for Cairo contract versioning is built to eliminate deployment risk and operational overhead for high-value StarkNet applications. We deliver predictable, auditable, and secure upgrade paths.
A centralized, on-chain record of all contract versions, deployment hashes, and changelogs. Provides a single source of truth for auditors, teams, and users to track the complete evolution of your protocol.
Integrated multi-sig and timelock controllers compatible with StarkNet's native account abstraction. Enforce rigorous approval workflows and mandatory cooling periods for all upgrades.
Pre-deployment analysis reports detailing storage layout changes, function selector collisions, and ABI breaks between versions. Prevents introducing critical vulnerabilities during upgrades.
Proactive contract versioning is a strategic investment, not just a technical task. Our custom StarkNet Cairo upgrade tooling delivers measurable business results, from protecting revenue to accelerating growth.
Execute protocol upgrades and critical security patches without halting your application. Maintain 24/7 availability for users and ensure continuous revenue streams during maintenance windows.
Adapt to new DeFi primitives, regulatory changes, and market demands without redeploying from scratch. Our upgrade frameworks enable modular logic swaps, keeping your protocol competitive.
Move beyond slow, multi-signature upgrade processes. Implement secure, automated upgrade paths with predefined rules, reducing time-to-market for improvements from weeks to hours.
Secure, transparent upgrade mechanisms prevent fund migration chaos and smart contract fragmentation. Users retain their token balances and positions seamlessly across versions.
Avoid the exponential cost of managing forked contracts and fragmented liquidity. A structured versioning strategy consolidates logic, simplifying audits and reducing maintenance overhead by over 60%.
Launch your MVP with upgradeability designed in from day one. Iterate rapidly based on user feedback without costly redeployments, compressing development cycles and capturing market share faster.
Compare the total cost, risk, and time investment of developing your own Cairo contract versioning system versus using Chainscore's managed service.

A systematic, security-first approach to building robust StarkNet Cairo contract versioning tools that ensure upgrade safety and developer velocity.
We define the versioning strategy (e.g., Diamond, Transparent Proxy) and create a detailed technical spec for your Cairo contracts, including upgrade paths and admin controls.
Development of the versioning logic, proxy contracts, and storage layout management in Cairo 1.0/2.0, adhering to OpenZeppelin upgrade patterns for StarkNet.
Rigorous unit and integration testing, plus a formal security review focused on upgrade vulnerabilities, reentrancy, and storage collisions.
We deploy the proxy and implementation contracts to StarkNet testnet/mainnet, verify source code on Voyager/Starkscan, and configure the upgrade admin multisig.
Delivery of comprehensive technical docs, upgrade scripts, and a CLI tool for managing future version deployments, ensuring your team owns the process.
Optional retainer for future contract version deployments, security monitoring, and advisory on StarkNet protocol updates affecting your upgrade system.
Secure, production-ready smart contracts built by experts for DeFi, NFTs, and enterprise applications.
We architect and deploy custom smart contracts that are secure, gas-optimized, and tailored to your specific business logic. Our development process ensures audit-ready code from day one, significantly reducing time-to-market and technical debt.
ERC-20, ERC-721, ERC-1155, ERC-4626, and custom implementations.OpenZeppelin libraries and following industry best practices for access control and upgradeability.We deliver battle-tested contracts that power real-world value, not just proof-of-concepts. Our clients launch with confidence, backed by rigorous testing and formal verification methodologies.
Get clear answers on our process, security, and delivery for StarkNet Cairo smart contract versioning and upgrade services.
Standard Cairo 1.0 upgrades for a single contract with comprehensive testing and security review take 2-3 weeks. Complex protocols with multiple interdependent contracts and custom upgrade logic typically require 4-6 weeks. We provide a detailed project plan with milestones within 48 hours of scoping.
