The Aura FHE architecture only matters if developers can build paradigm-shifting applications with it. Our protocol unlocks entirely new categories of decentralized applications that were fundamentally impossible on transparent blockchains. Everything in our ecosystem is either live today, in active development with institutional partners, or immediately buildable using our current software development kit.
Sealed-Bid Prediction Markets
AuraPoly serves as our flagship production application and is officially live, clearing real flow on the Aura encrypted compute layer. It operates as a sealed-bid prediction market where a half-million dollar fill stays completely invisible until the moment it settles on-chain. By utilizing FHE, we ensure zero information leakage between participants, solving the structural problem of large fills moving the price before execution.based FHE schemes require a time-consuming refresh process called bootstrapping that creates a structural bottleneck. Every encrypted operation in lattice-based FHE introduces noise into the ciphertext. The ciphertext must be bootstrapped, homomorphically decrypted and re-encrypted, refreshing the noise. The fastest production implementations measure bootstrapping in tens of milliseconds per gate. A 400ms Solana block cannot accommodate this. AURA FHE abandons lattice-based FHE entirely and solves this speed-to-privacy mismatch by replacing ring-based ciphertext arithmetic with precomputed lookup tables, known as LUT-FHE, defined over a Multivariate Quadratic structure.
Confidential AI Inference
The Aura coprocessor also supports FHE-based Artificial Intelligence inference. This allows sophisticated models to run on encrypted prompts without ever decrypting the input, returning secure outputs that only the specific user can read. This technology enables high-stakes, privacy-critical workloads such as medical diagnostic AI on patient records, legal AI on privileged documents, and financial advisory tools on private portfolio positions.
Institutional Real-World Assets and DeFi
Tokenized real-world assets represent a multi-trillion-dollar market that cannot operate on transparent rails due to commercially sensitive counterparty positions and settlement amounts. Aura FHE provides the critical encryption layer that makes regulated RWA tokenization viable on Solana's public infrastructure. Additionally, our primitives enable encrypted order books for decentralized exchanges and dark pools, allowing wholesale institutional capital to execute large trades without leaking their positions to MEV bots watching the mempool.
Three Lines to Total Privacy
AURA SDK v5 is live in production, empowering developers to build the next generation of on-chain finance with privacy by default. Our SDK exposes three highly optimized core primitives: encrypt, compute, and decrypt. With this straightforward interface, a Solana developer can take any existing transparent program, modify just three lines of code, and ship a fully confidential version in under an hour. This seamless integration instantly unlocks a library of higher-level constructs for real-world applications, including encrypted swaps, sealed-bid auctions, and confidential balances.
