Encrypted RNG Oracle Service

Deliver provably fair and unpredictable randomness for your on-chain applications. We build secure, encrypted RNG oracles that guarantee confidentiality and verifiability for gaming, NFTs, and lotteries.
Chainscore © 2026
overview
CORE SERVICE

Smart Contract Development

Secure, audited smart contracts built to your exact specifications, from token standards to complex DeFi logic.

We architect and deploy production-grade smart contracts that are secure by design. Every contract undergoes rigorous internal review and is built with OpenZeppelin standards and Solcurity patterns to mitigate risks from day one.

  • Token Systems: Custom ERC-20, ERC-721, and ERC-1155 contracts with advanced features like vesting, minting controls, and governance hooks.
  • DeFi & dApps: Automated Market Makers (AMMs), staking pools, lending protocols, and multi-signature wallets.
  • Enterprise Logic: Custom business logic for supply chain, identity, and asset tokenization on EVM-compatible chains.

We deliver a fully tested, deployment-ready contract suite in 2-4 weeks, complete with documentation and a security audit report.

Core Capabilities of Our Encrypted RNG Oracle

Our oracle delivers verifiably fair, on-chain randomness with enterprise-grade reliability, designed for high-stakes applications like gaming, DeFi, and NFT minting.

01

Cryptographically Verifiable Randomness

Deliver provably fair, tamper-proof random numbers using a commit-reveal scheme with VRF (Verifiable Random Function). Every generated number is cryptographically signed and can be independently verified on-chain, ensuring complete transparency and fairness for your users.

Frequently Asked Questions

Get clear answers about our verifiable random number generation service, from integration to security.

Our oracle uses a multi-layered, verifiable random function (VRF) architecture. We combine on-chain commitments with off-chain computation using drand's threshold BLS signatures, ensuring the random number is unpredictable, publicly verifiable, and tamper-proof. All responses are encrypted end-to-end, and the private key for decryption is never exposed on-chain. We have undergone third-party audits of our VRF smart contracts and relay infrastructure.
