Entropy
Secure, Verifiable Random Number Generator for EVM-based smart contracts
Pyth Entropy is an on-chain random number generator (RNG) designed for developers who need fair, unbiased, and cryptographically secure randomness. Whether you're building a blockchain game, NFT mint, lottery, or simulation, Entropy delivers randomness that is:
- Trustless & verifiable - built on commit-reveal protocol.
- Low-latency - randomness available within a few blocks.
- Easy to use - get started in < 5 minutes, no registration required.
- Cost-efficient - designed for scalable production use fees.
- Native gas fees - pay with chain native token.
