API3 QRNG

API3 is a Swiss blockchain technology company founded in 2020 that partnered with Australian National University (ANU) Quantum Optics Group to launch API3 QRNG in May 2022, the first true random number generator for smart contracts using quantum vacuum fluctuations. The quantum random numbers use electromagnetic field vacuum fluctuations measured through balanced homodyne detection, providing ultra-high bandwidth truly unpredictable randomness for blockchain and Web3 applications. API3 QRNG is free to use (only gas fees), available on 13 blockchain platforms including Polygon, Avalanche, Fantom, Metis, Moonbeam, and RSK. The system uses encrypted data transmission via Amazon Web Services, destroying random numbers after use for security. Applications include gaming, NFTs, lotteries, crypto wallet generation, and blockchain applications requiring quantum-level unpredictability. API3 QRNG addresses Web3 security demands by providing quantum mechanics-based randomness for decentralized applications, smart contracts, and cryptographic operations. The service serves blockchain developers, DeFi platforms, gaming applications, and cryptocurrency projects requiring provably random numbers from quantum processes.
