Secure, production-ready smart contracts built by Web3-native engineers.
We architect and deploy custom smart contracts that form the secure backbone of your application. Our development process is built on audited patterns and gas-optimized code to ensure reliability and cost-efficiency from day one.
Deploy with confidence using contracts that have passed rigorous internal and third-party audits.
Our development stack includes:
Deliverables you receive:
We focus on security-first development to protect your assets and users, turning your protocol vision into a live, auditable system.
We architect, implement, and maintain secure, verifiable randomness for your Web3 applications, from gaming and NFTs to DeFi and governance. Our solutions are production-ready, audited, and designed for scale.
Tailored randomness logic for your specific use case—NFT minting, game mechanics, or protocol governance. Built with Solidity 0.8+ and OpenZeppelin libraries, following security best practices.
All VRF integrations include comprehensive unit testing, integration testing, and are structured to pass third-party security audits. We provide detailed documentation and a formal verification report.
Deploy your VRF-powered application across any supported network. We manage the configuration and deployment pipeline for Ethereum, Polygon, Arbitrum, Optimism, and other L2s.
Proactive monitoring of your VRF requests, subscription balances, and contract health. We provide 24/7 alerting and SLA-backed support to ensure uptime and reliability.
We deliver clean, documented APIs and SDKs for your frontend team. Includes integration guides, example code, and direct support to accelerate your product's time-to-market.
Move beyond centralized RNG and integrate a secure, transparent, and verifiable source of randomness that is essential for building trust and fairness in your Web3 applications.
Eliminate user skepticism with on-chain cryptographic proofs. Every random output is verifiable by anyone, ensuring your NFT drops, gaming outcomes, and protocol operations are provably fair.
Our VRF is built on battle-tested cryptographic primitives with a secure off-chain computation layer. Protect your application from manipulation and front-running attacks that plague simple on-chain RNG.
Avoid the volatility and high fees of on-chain randomness solutions. Our pre-paid request model provides predictable, low-cost randomness, making your application's economics stable and scalable.
Designed for high-throughput dApps. Achieve sub-second latency for randomness delivery with 99.9% uptime, supporting everything from high-frequency gaming to large-scale NFT launches.
Get from zero to production in days, not months. Our simple API and comprehensive SDKs (Solidity, Rust, JS) abstract away cryptographic complexity, letting you focus on your core product.
Simplify compliance for gaming and financial applications. Our tamper-proof audit trail and verifiable proofs provide the transparency required by auditors and regulatory bodies.
Choosing between building a custom Verifiable Random Function solution or using Chainscore's managed service impacts your time-to-market, security posture, and total cost of ownership. This comparison highlights key operational and financial factors.

A streamlined, four-phase approach to integrate production-ready, secure VRF into your dApp, minimizing risk and accelerating your time-to-market.
We analyze your dApp's architecture to design the optimal VRF integration strategy. We specify request models, callback logic, and gas optimization patterns tailored to your use case (NFT minting, gaming, lotteries).
Our engineers implement the VRF consumer contracts using audited OpenZeppelin patterns. We handle subscription management, request fulfillment, and secure randomness consumption with comprehensive unit and integration tests.
Every integration undergoes rigorous internal review and simulation testing on testnets. We verify randomness fairness, prevent front-running, and ensure contract resilience against common attack vectors before mainnet deployment.
We manage the mainnet deployment, configure Chainlink subscriptions, and set up real-time monitoring dashboards. You get alerts for request failures, subscription balances, and fulfillment latency.
We deliver verifiable randomness for your dApp using battle-tested protocols and secure, audited infrastructure. Our integrations are designed for high-throughput applications requiring provable fairness.
All VRF integrations include security reviews following OpenZeppelin patterns. We ensure your randomness logic is resistant to manipulation and front-running attacks.
Deploy your VRF-powered application across Ethereum, Polygon, Arbitrum, Optimism, and other EVM-compatible networks. We manage cross-chain configuration and verification.
Get real-time dashboards for request success rates, gas consumption, and oracle latency. We set up proactive alerts for failed requests or subscription depletion.
Answers to the most common questions from CTOs and technical leads evaluating secure, on-chain randomness for their applications.
Standard VRF integration and deployment takes 2-4 weeks from kickoff to mainnet launch. This includes smart contract development, Chainlink/API3 oracle setup, frontend integration, and security review. Complex use cases like multi-chain lotteries or advanced gaming mechanics may extend to 6-8 weeks.
