CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built for scale and compliance.
We architect and deploy custom Solidity/Rust smart contracts with a focus on security-first development. Every contract undergoes a multi-stage audit process, including automated analysis and manual review, before deployment to mainnet.
- Full Lifecycle Management: From initial design and
OpenZeppelinintegration to deployment, verification, and upgradeability planning. - Gas Optimization: Expert-level code to minimize transaction costs, a critical factor for user adoption.
- Compliance & Standards: Built-in support for
ERC-20,ERC-721,ERC-1155, and custom tokenomics with regulatory considerations.
Our contracts are built for real-world use, not just proofs-of-concept. We ensure your logic is battle-tested, your assets are protected, and your platform is ready for high-volume transactions from day one.

Frequently Asked Questions
Get clear, technical answers about integrating verifiable randomness into your Web3 applications.
Our SDK provides a client-side library that connects to Chainscore's decentralized oracle network. It requests randomness by submitting a request to a smart contract, which triggers a commit-reveal process by a network of independent node operators using Verifiable Random Functions (VRFs). The result is cryptographically proven to be tamper-proof and unpredictable, with on-chain verification. We use a multi-chain approach with fallback providers to guarantee 99.9% uptime.
