AURA is not five products. It is one protocol expressed across five layers, each of which generates demand for the next. The layers ship in deliberate sequence, and the alignment is what makes the whole greater than the sum.
Layer 1: The SDK — where developers touch the network
The SDK is the entire economic stack's mouth. Without developer adoption, none of the other layers have demand. Every dApp that integrates AURA generates ongoing fee flow to the coprocessor network, which compensates miners, which gives the token utility, which funds further development. The SDK is therefore the single most important artifact in the protocol.
AURA SDK v5 ships in production today. It exposes three core primitives — aura.encrypt(field), aura.compute(op, ciphertext), and aura.decrypt(handle) — and a library of higher-level constructs that map to real dApp categories: encrypted swaps, sealed-bid auctions, confidential balances, private governance, hidden-LP AMMs. A Solana developer can take an existing program, modify three lines, and ship a confidential version to devnet in under an hour.
The SDK is privacy-by-default. Developers must explicitly opt out of encryption for any field, the inverse of how every existing chain operates. Privacy as opt-in produces transparent dApps with privacy tacked on. Privacy as opt-out produces an ecosystem of confidential applications with transparency where strictly necessary. The latter is what builds the next generation of on-chain finance.
Layer 2: The AURA Token — gas for encrypted computation
AURA is the unit of account for every encrypted computation processed by the network. The framing is deliberate and exact: just as ETH pays for transparent computation on Ethereum and SOL pays for fast computation on Solana, AURA pays for private computation on every chain that integrates the protocol — and on every off-chain workload that needs verifiable confidential compute.
Layer 3: The Aura Wallet — the consumer surface
The wallet is what turns AURA from B2B infrastructure into a consumer protocol. Without a wallet, AURA reaches developers and enterprises. With a wallet, AURA reaches end users — the population that ultimately decides which infrastructure becomes culturally inevitable.
The Aura Wallet ships with three encryption primitives baked in by default. Encrypted balances mean that connecting a wallet does not expose net worth. Encrypted swaps route through any AURA-SDK-integrated DEX with sealed order flow, eliminating front-running at the user level. Encrypted social transfers allow a user to send funds to a friend without the entire chain seeing the amount or the relationship.
The wallet is also a direct token sink. Every wallet user holds a small AURA balance to pay for their own encrypted operations. At 100K monthly active users by 2027, this is a measurable, recurring, non-speculative source of AURA demand — the kind of metric that anchors a Series A valuation.
Layer 4: The Coprocessor & Mining Protocol — the compute substrate
The coprocessor network is the physical infrastructure that makes everything else work. Miners worldwide contribute GPU and specialized compute capacity, execute FHE workloads against encrypted requests routed by the SDK, return verifiable ciphertext outputs, and earn AURA in proportion to verified work.
The mining protocol — Proof of Encrypted Work (PoEW) — is designed in two distinct phases:
- Genesis phase (Q4 2026 through Q4 2027) — bootstrap miners with a fixed token emission curve. Emissions during this phase are a startup subsidy that builds redundant capacity ahead of demand. Genesis emissions are capped at 25% of total supply over 18 months and the schedule is published in advance.
- Steady-state phase (Q1 2028 onward) — miners earn from real protocol fees generated by SDK usage.
Layer 5: The Global Ecosystem — beyond Web3
The structure of AURA's coprocessor architecture means that the same protocol that serves a Solana DEX can serve a hospital, a hedge fund, a government agency, or an AI inference pipeline. The cryptography does not care whether the request originated from a smart contract or from a REST API. The economic model — fees in AURA, work performed by miners, yield to stakers — does not change.
