SolanaVault vs Helius: when decentralization actually changes the math

Two products, two philosophies

Helius is a hosted Solana RPC and DAS API provider with one of the best developer experiences in the ecosystem. SolanaVault is a peer-to-peer compression and storage network with a drop-in Solana JSON-RPC interface. Both serve getConfirmedBlock. Only one lets you keep the gateway revenue.

If you are shipping a wallet that needs a fast RPC for live transactions, Helius is a great answer. If you are running an indexer, an explorer, an analytics product, or any workload that reads more historical block data than it writes new transactions, the math changes.

Where each one wins

Helius wins on: hosted convenience, the DAS API for compressed NFTs, the polished dashboard, geographic POPs, and a free tier that is generous enough for most weekend projects. Their team ships fast and answers Discord questions.

SolanaVault wins on: 15-25:1 compression on stored blocks, microsecond decompression latency, an explicit revenue share for gateway operators, MIT/Apache-2.0 source for the full stack, and an architecture where no single party can revoke your access.

The compression argument

Most hosted providers do not compress block payloads at the storage layer. They run hot copies of the ledger in RAM-heavy boxes because their margin depends on read speed, not storage cost. That is fine — until you are the customer paying for that read speed on data you only read once a quarter.

SolanaVault treats compression as the primitive. Our v3 production pipeline encodes a typical Solana block in under a millisecond and decodes it in 13 to 85 microseconds. The wire payload is about a fifteenth to a twenty-fifth of the original. That means a gateway can serve a hundred queries from the same RAM page that a non-compressing provider needs for four.

When that ratio compounds across a long-tail historical workload, the unit economics flip. The price per million queries is not the same product anymore.

Decentralization that you can operate

“Decentralized” is a word that gets stapled onto a lot of things. Here is what it actually means in SolanaVault:

• Peer discovery is Kademlia DHT. There is no privileged registry.
• Transport is NNG sockets. There is no proprietary message bus.
• Consensus is Byzantine quorum on every read. There is no trusted oracle.
• Reputation is on-network. Lying nodes get slashed.

Helius runs excellent infrastructure. But it is their infrastructure. If a regulator, a payments provider, or a contractual change reorders their priorities, you do not have an option. With SolanaVault, you can become an operator yourself in an afternoon and keep 85% of the revenue.

What we tell teams to do

• If your workload is mostly sendTransaction and getSignatureStatuses against the live tip, start on Helius. The latency is excellent and the DX is hard to beat.
• If your workload reads more than 25M historical RPC calls per month, run the same load against a Vault Cloud Builder workspace. The price difference is usually 60-80% in our favor before you factor in egress.
• If you operate at scale and want to control the supply chain, run your own SolanaVault gateway. Pin a private namespace if you want isolation.

Closing thought

We genuinely respect what the Helius team has built. We are not here to replace a polished hosted RPC. We are here to make sure that when the bill arrives, you have a credible alternative — and that the alternative happens to be cheaper, faster on cold reads, and open-source under a real OSI license.
