Cachee is AI-powered distributed cache infrastructure for Solana validators, RPC providers, indexers, MEV builders, and analytics platforms. Evidence-backed outcome caching eliminates duplicated account-state lookups, cuts transaction-history queries, and removes redundant PnL recomputation. Downstream systems independently verify the cached result without re-running the verification and without trusting the cache operator. H33-74 attaches a 74-byte post-quantum evidence reference to each cached outcome; H33's cryptographic replay reconstructs the trust path. Cachee stores and serves across the industry's migration off Ed25519.
Real Helius RPC, real Jupiter treasury wallet, real Solana mainnet transactions. The first PnL computation is cold — Cachee fetches and computes from scratch. Every subsequent computation, by any consumer, returns from cache with a post-quantum attestation.
One verified result anchors the source of truth for every downstream consumer — analytics platforms, dashboards, tax calculators, portfolio trackers, trading bots — eliminating the JSON-RPC fan-out, the transaction parsing, and the PnL math for everyone after the first. They verify the 74-byte attestation; nobody re-executes the computation. Read the full benchmark →
The H33-74 evidence element — not Cachee — lets independent parties trust each cached outcome without trusting the cache operator. That single property converts Solana verification from a per-system cost into a shared, portable asset — the foundation of distributed verification infrastructure.
— The category shift
Solana's throughput is a gift and a curse. The chain produces thousands of transactions per second, and every consumer of that state — validators, RPC providers, indexers, analytics platforms, PnL calculators, tax engines, dashboards, MEV searchers, DEX aggregators, trading bots — pays the cost of parsing, validating, and re-querying it, over and over.
A single Helius RPC call to compute treasury PnL across thousands of transactions costs ~2 seconds and pulls compute, bandwidth, and historical state. The next consumer asking the same question pays the same cost. That's the structural waste. The verification work isn't expensive because Solana is slow — it's expensive because nobody can share the result.
Cachee's Helius integration proves the point. One verified PnL computation is distributed as a portable attested receipt. Every downstream consumer reads the cached answer at 0.05ms and independently verifies the 74-byte attestation. The cost collapses from per-consumer to per-attestation — a roughly 39,000× compression of duplicated compute.
Operational line items Solana infrastructure teams pay for every day. Each one collapses from per-consumer → per-attestation with portable verification receipts.

Cachee delivers a cached attested account snapshot the next consumer trusts via attestation, not via the RPC.A single cached verification result anchors the source of truth for every downstream consumer. The post-quantum attestation is what makes each cached outcome independently verifiable without trusting Cachee — the H33-74 evidence reference, not the cache, anchors trust — eliminating the per-consumer re-execution tax.
Cachee does not generate attestations. Cachee does not verify them. The architecture works because three independent layers compose: Cachee stores. H33-74 attests. Replay reconstructs.
This three-layer composition is what “verifiable computation caching” actually means: not Cachee acting as a trust anchor, but Cachee as the high-speed delivery layer for outcomes that H33-74 makes independently verifiable.
Solana, like most modern chains, is built on Ed25519 signatures — an elliptic-curve scheme the cryptography community expects to break with sufficiently large quantum computers. The entire validator stack, every account signature, every transaction proof, every program call inherits a single hardness assumption.
Cachee's attestations are post-quantum from inception. The 74-byte verification receipt is signed by three independent post-quantum primitives: ML-DSA (lattice), FALCON (NTRU lattice), and SLH-DSA (stateless hash). Breaking the attestation requires breaking three independent mathematical bets simultaneously.
The practical consequence: cached Solana verification receipts remain portable through the industry's migration to PQ cryptography. Validator infrastructure, RPC providers, custody platforms, and settlement layers built against Cachee today don't need to redo their trust assumptions when quantum computers arrive — or when NIST tightens the standards, or when an EC-side vulnerability is disclosed.
For long-lived Solana infrastructure — institutional custody, regulatory reporting, multi-year analytics archives, restaking-secured liquid-staking systems — post-quantum portability isn't a feature. It's the only honest design choice.
Concrete surfaces where portable verification pays for itself immediately.
getAccountInfo calls millions of timesThe pattern repeats anywhere Solana state is read more often than it changes: account state caching, transaction history querying, RPC acceleration, validator performance, MEV opportunity scanning, indexer replay, PnL computation, fork choice resolution. Cachee compresses the verification cost from per-consumer to per-attestation — and the attestation is post-quantum, so the cost collapse survives the PQ migration.
Solana doesn't live alone. Polygon zkEVM bridges read Solana state. Bitcoin-anchored sidechains consume Solana settlement proofs. Cross-chain DEX aggregators trust Solana liquidity for cross-rollup routing. Every one of those systems pays the full Solana verification cost today — and pays it per-consumer, per-chain, per-relay.
H33-74's evidence primitive — served by Cachee — is chain-agnostic. The 74-byte receipt produced by the Solana cache layer is the same primitive reused by the Bitcoin and Polygon zkEVM cache layers. A Solana slot, verified once on Cachee, is distributed as a portable computation receipt that a Bitcoin bridge, a Polygon zkEVM program, and any rollup with a Solana dependency independently verify — without re-running Solana validation, eliminating duplicated cross-chain compute.
This is what "cross-chain result reuse" actually means. Not a bridge token. Not a wrapped asset. The verification itself is the asset.
If you operate one of these and pay for verification compute repeatedly — Cachee turns that bill into a single attestation.
Solana economics are dominated by throughput on the producer side and repeated read cost on the consumer side. The chain produces thousands of transactions per second; every downstream system pays the cost of independently re-verifying that state. When that cost moves from per-consumer to per-attestation, three things happen.
Marginal cost of a new consumer collapses. Adding a new dashboard, analytics platform, trading bot, or wallet integration no longer means adding a new full pass of RPC fan-out and verification. The new consumer reads the existing attestation. RPC providers stop scaling node fleets linearly with customer count.
Cross-system trust collapses to zero cost. Two systems that don't trust each other — a wallet and an exchange, an analytics platform and a custodian, an indexer and a tax engine — agree on Solana state without either operating validator infrastructure. Both verify the attestation; neither re-executes the verification.
The trust model shifts to post-quantum. Long-lived Solana infrastructure built against Cachee inherits a 74-byte attestation that survives the EC → PQ migration. Custody, settlement, and regulatory reporting design verification receipts that are never redone when the cryptographic ground shifts.
This is what we mean by Solana scaling infrastructure. Not bigger blocks. Not faster RPC nodes. Verification that doesn't need to be repeated.
Pair the Solana cache layer with Bitcoin and Polygon zkEVM — one post-quantum attestation primitive, three live integrations, cross-chain by design.
