Secure, production-ready smart contracts built by Web3 experts to power your decentralized applications.
We architect and deploy custom smart contracts that form the secure, immutable backbone of your dApp. Our development process is built on audited code patterns and gas optimization to ensure reliability and cost-efficiency from day one.
We deliver contracts you can trust, with a focus on security, scalability, and seamless integration.
Our development stack & process:
Solidity 0.8+, Hardhat, Foundry for EVM chains; Rust for Solana/Ink!.OpenZeppelin standards.Why choose Chainscore:
We deliver production-ready, secure, and scalable ZK-powered gaming asset systems. Our focus is on technical depth, verifiable security, and measurable outcomes that accelerate your product roadmap.
Development of custom ERC-721/1155 contracts with integrated zero-knowledge proofs for provable ownership, privacy-preserving transfers, and off-chain state verification. Built with industry-standard libraries like Circom and Noir.
Smart contract architecture designed for high-frequency gaming transactions. We implement gas-efficient patterns, batch operations, and layer-2 native designs to minimize user costs and maximize scalability.
From design to deployment, security is paramount. Our process includes threat modeling, automated testing with Foundry/Hardhat, and formal verification for critical logic. Final delivery includes a comprehensive audit report.
Secure bridge architecture for gaming assets across Ethereum, Polygon, Arbitrum, and other EVM chains. We implement canonical bridges or third-party solutions (LayerZero, Axelar) based on your security and latency requirements.
Smart contract modules that enforce creator royalties on secondary sales and maintain an immutable provenance trail for each asset. Configurable fee structures compliant with marketplace standards.
We don't just deliver contracts. You receive a full integration package: TypeScript SDK, admin dashboards, deployment scripts, and documentation to empower your engineering team post-handoff.
We translate zero-knowledge cryptography into concrete business advantages for your studio. Our development process is built on verifiable results, not just technical promises.
ZK-based asset contracts with formal verification and 3rd-party audits (e.g., CertiK, OpenZeppelin) to eliminate exploits and build player trust. We deliver contracts with a documented security posture.
Contracts engineered for sub-50k gas for core interactions (mint, transfer), reducing player transaction costs by up to 70% compared to standard implementations, directly improving user retention.
Future-proof ERC-1155 and custom ZK extensions that ensure compatibility with major marketplaces (OpenSea, Blur) and wallets, accelerating time-to-integration for your partners.
Deployment on high-throughput ZK rollups (zkSync, Starknet) or app-chains with dedicated RPC endpoints, guaranteeing sub-second finality and 99.9% uptime for in-game economies.
A developer SDK for your team to easily build on-chain game mechanics (staking, crafting, tournaments) without deep ZK expertise, reducing internal development time by months.
Design patterns for jurisdictional compliance, including transfer pausability, verified operator lists, and on-chain provenance tracking to meet evolving global standards.

A structured, security-first approach to deliver production-ready ZK-powered gaming assets. We focus on rapid, auditable delivery that integrates seamlessly with your game engine and marketplace.
We define your asset's on-chain logic, ZK proof requirements, and gas-efficient data structures. This includes selecting the optimal token standard (ERC-1155 for fungible items, ERC-6551 for composable NFTs) and finalizing the privacy model.
Our engineers write, test, and optimize Solidity/Vyper contracts using OpenZeppelin libraries. We implement the ZK circuit logic (using Circom or Halo2) for private state verification and build the off-chain prover/verifier system.
Every contract undergoes automated analysis (Slither, MythX), manual review by our senior auditors, and integration testing with your game client. We prepare a comprehensive security report before mainnet deployment.
We provide SDKs and APIs (Unity/Unreal Engine) for minting, transferring, and verifying ZK assets in-game. This includes wallet connection, transaction signing, and real-time state synchronization with the blockchain.
We manage the secure deployment to your chosen L1/L2 (Ethereum, Polygon, Arbitrum), configure indexers (The Graph), and set up monitoring (Tenderly, OpenZeppelin Defender) for production oversight and incident response.
Post-launch, we offer maintenance packages for protocol upgrades, new feature integration, and performance optimization. We ensure your asset contracts evolve with the ecosystem and remain secure.

Answers to common questions from CTOs and product leads evaluating ZK-based asset development partners.
We deliver a production-ready, audited ZK asset contract system in 4-8 weeks from kickoff. A standard project includes 2 weeks for architecture and circuit design, 3-4 weeks for core development and internal testing, and 1-2 weeks for third-party audit integration and deployment. Complex integrations (e.g., custom game engines, multi-chain) may extend this timeline, which we scope and agree upon upfront.
