ORAO Network

ORAO Network is an oracle infrastructure platform founded in 2020. Its stated mission is to provide general-purpose data availability across any blockchain. In practice its most mature and actively used product is a Verifiable Random Function (VRF) oracle deployed on Solana mainnet, which supplies decentralized applications with cryptographically provable, unbiased randomness.

Solana VRF: How It Works

The Solana VRF product uses an EDDSA-based multi-party architecture rather than a single aggregator model. When a Solana program requests randomness, it does so by writing to a dedicated on-chain randomness account. A network of independent fulfillment nodes monitors those accounts, each independently generates a random value, and submits it on-chain. The ORAO VRF program then validates each node's cryptographic signature and combines contributions via an XOR operation. Randomness is only stored on-chain once a Byzantine quorum of nodes has submitted valid responses, so no single node can bias the outcome.

The result is sub-second to low-single-digit-second fulfillment at a fixed cost of 0.001 SOL per request — meaningfully cheaper and faster than aggregator-based competitors. ORAO publishes a direct comparison on its site showing fulfillment times of sub-second to 4–20 seconds against several minutes for Switchboard's aggregator approach, at roughly one-seventh the cost per request.

The fulfillment program lives at Solana mainnet address VRFzZoJdhFWL8rkvu87LpKM3RbcVezpMEc6X5GVDr7y. The latest npm release of the JavaScript SDK (@orao-network/solana-vrf) was published in August 2026, and the GitHub repository shows ongoing maintenance with 70+ commits. Developers can integrate via Rust (Anchor-based SDK) or JavaScript/TypeScript, both of which support Cross-Program Invocation (CPI) so that VRF requests can be embedded inside a caller program's transaction flow. ORAO ships a working Russian Roulette example contract to illustrate CPI integration patterns.

Practical use cases for the VRF include assigning unique trait combinations to NFTs at mint, generating loot tables and game outcomes in on-chain games, randomizing airdrop recipient selection, and powering verifiable lotteries.

Additional Products

Beyond Solana VRF, ORAO is extending its oracle stack in two directions.

zkVRF on Polygon uses zero-knowledge SNARKs (built with the Zokrates framework) to deliver verifiable randomness with privacy guarantees. A Phase 2 multi-party trusted setup ceremony for the zk VRF circuit was completed in January 2026, indicating continued development of this product.

Fuel VRF is a randomness oracle for the Fuel blockchain. The repository was updated as recently as August 2025.

Pricing Oracles is a configurable market-data feed product that the team is building out. The product allows customization of outlier-detection thresholds (e.g., slippage tolerance) and latency settings tuned to a target chain's block time. Support for EVM chains and NEAR protocol is listed as a planned extension. Coverage claimed on the main site describes tens of thousands of crypto markets and trading pairs, though the live pricing feed interface appeared incomplete at time of research.

ORAO Token

The ORAO token is the platform's utility asset. Data providers must stake ORAO on the blockchains where they operate, and users need ORAO to purchase data or to qualify as providers themselves. The token was distributed through DaoMaker's launchpad in 2021–2022, raising approximately one million dollars at a public sale price of 0.015 USDC per token.

Total supply is fixed at 1 billion ORAO tokens. As of mid-2026, approximately 39.4 million tokens (3.94% of total) are in circulating supply. The allocation at launch was: team 20%, foundation 34%, advisors 10%, seed sale 9%, private sale 10%, public sale 16%. The token reached an all-time high of roughly 0.055 USDC in July 2021 and has traded at a fraction of that since.

Security and Audits

The project received a security audit from Hacken. It also holds a CertiK security rating of 2.9. Independent audit details beyond these two engagements were not found in publicly available materials as of this writing.

Solana Ecosystem Fit

ORAO's Solana VRF fills a specific and persistent need in the Solana developer ecosystem: on-chain randomness that is both cheap and fast enough to use inside interactive applications and games. The program's Byzantine quorum model means no single oracle operator can manipulate outcomes, making it suitable for high-stakes use cases like lotteries or competitive game mechanics where predictable randomness would be exploitable.

The VRF is included in the Solana Cookbook as a documented integration pattern, giving it some standing as a community-recognized option. Its sub-second fulfillment target aligns well with Solana's block time characteristics, and its low per-request cost of 0.001 SOL keeps it viable even for high-frequency applications like games that generate many random events.

ORAO's multi-chain expansion (Polygon zkVRF, Fuel VRF, planned EVM and NEAR pricing oracles) positions it as a general oracle infrastructure provider rather than a Solana-only project, but Solana remains the ecosystem where its product is most mature and actively maintained.
