Last updated 5 months ago

Supra’s decentralized dVRF is designed to power dApps with effectively random outcomes that are responsive, scalable, and easily verifiable.

Benefits

Low-Latency Response

For seamless user experiences, actions need to respond quickly. For instance, clicking open a lootbox should show the prize instantly. That’s exactly what our on-chain dVRFs are designed for. The novel architecture of Supra dVRFs can compute and ship random outcomes in just moments, not minutes.

Designed to Scale

Scale is crucial for growth as Web3 moves towards greater adoption. This calls for scale throughout the on-chain development stack, including VRFs. Our network leverages batching to achieve greater network efficiency as well as lower costs.

Truly Decentralized

Centralized dVRFs pose a single point of failure threat. Supra dVRFs use a secret sharing algorithm to distribute power across multiple nodes, so no one node has the power to compromise your apps or users.

Natively Cross-chain

Supra dVRF solves on-chain randomness for Web3 at large, not just a few networks. We’re already on 27 networks like Aptos, Arbitrum, Avalanche, Ethereum, Optimism, and Polygon.

Provable with a public key

Good randomness needs to be unbiased, unpredictable, and most importantly — verifiable. Our dVRF outputs are easily verifiable on-chain with a public key, so you can always prove to anyone that all outcomes are truly random and unbiased.

Affordable & accessible

Randomness is a basic need in a decentralized world, yet it's been out of reach for most dApps. With network efficiency and cross-chain scaling techniques, we’re bringing Supra dVRFs to blockchains far and wide at significantly lower costs.
