Helios Proofs
Zero-knowledge proofs, as one API call.
Helios turns any computation into a verifiable zero-knowledge proof through a single REST endpoint. No circuit engineering, no proving cluster, no cryptography PhD. Send a program and inputs, get back a succinct proof and an onchain verifier.
Helios Proofs
Zero-knowledge proofs, as one API call.
The why, in the customer's words
Helios is the proving API that ships zero-knowledge in an afternoon, not a PhD: send a program, get back a proof and a verifier, with no circuit code.
- 1Teams that want verifiable computation today are told to hire cryptographers and stand up a proving cluster first.
- 2Helios is a hosted proving API: you POST a program and inputs and get back a succinct proof plus an onchain verifier.
- 3Unlike rolling your own with a proving framework, you ship in an afternoon and never operate proving infrastructure.
Bottom-up: ~52,000 active onchain dev teams (Electric Capital 2025) x ~$60K/yr blended spend on verifiability and security tooling.
Teams on EVM L2s shipping features that need verifiable compute today (~12% of active teams) x $34K/yr.
Conservative year-1: 120 paying teams at ~$12K/yr average across usage tiers.
| Them | Helios Proofs | |
|---|---|---|
| Time to first proof | Weeks to months | Hours |
| Who operates proving | You, on-call | Helios |
| Cryptography expertise needed | High | None |
Killer question: “Who on your team is on-call for the proving cluster at 3am the week you launch?”
When you lose: Teams that already have a cryptography team and want full control of the circuit stack.
| Them | Helios Proofs | |
|---|---|---|
| Audit risk | Flagged trust assumption | Verifiable |
| Cost | $0 now, risk later | Usage-based |
Killer question: “What happens to this feature in your next audit?”
When you lose: Pre-revenue prototypes where no one is asking for proofs yet.
A major zkVM framework ships a one-click hosted mode and collapses the gap.
MediumCompete on conversion-data defaults and the integration-success record, not raw proving; stay framework-agnostic so we host theirs too.
Proving costs stay high enough that usage pricing scares teams off.
MediumTiered batching and a free first proof; price on verified outcomes, not raw cycles.

}Ship zero-knowledge in an afternoon
Send a program, get back a proof and a verifier. No circuits, no cluster, no PhD.
Get your first proofProof, from real testers
Testers are paid a flat bounty to run a real integration and report honestly. They are never paid to praise. Reviews are unedited.
127 testers. Backend and protocol engineers recruited from ETHGlobal cohorts, rollup Discords, and the Helios waitlist.
“We had a proof verifying on a testnet in three days. The honest part: docs for batch mode were thin and I filed two issues, both fixed within a week.”
“Saved me from learning circuit design. Cold-start latency on the first proof of the day is real, and they are upfront about it.”
“The Solidity verifier dropped in clean. I expected to fight it for a day; it took an hour.”
“Cleared the audit finding we needed it for. Wanted more control over proving parameters; that is on their roadmap, not shipped.”
The conversion-data flywheel
Because Aloran ran the validation, it sees which articulation and which brand actually converted. This is the part competitors structurally cannot reproduce.
| Variant tested | Type | Impressions | Conversion | |
|---|---|---|---|---|
"Ship ZK in an afternoon" Time-to-ship framing, leads with speed. | articulation | 4,200 | 8.8% | winner |
"Zero-knowledge without a PhD" Expertise-removal framing. | articulation | 4,050 | 5.4% | |
"Verifiable compute, hosted" Category-accurate, feature-first framing. | articulation | 3,980 | 3.3% | |
Luminous / dark technical Deep navy with a single luminous accent. | brand | 6,100 | 7.7% | winner |
Clean docs-style light White, developer-docs aesthetic. | brand | 6,030 | 4.9% |
- →Speed-to-ship beats expertise-removal by 63% for this ICP. Engineers buy the deadline, not the absence of a PhD.
- →The category-accurate framing ('verifiable compute') converts worst. Being correct is not the same as being legible.
- →A dark, luminous brand outperformed the docs-style light theme; this audience reads 'serious infra' as low-key and high-contrast.

Saw your thread about scoping a bridge state check and hitting the circuit wall. Helios is a hosted proving API: POST a program and inputs, get back a succinct proof and a Solidity verifier. No circuit code. We pay a flat $400 bounty to run one real integration and write up what broke, honestly. Four of the last six testers had a proof on a testnet inside a week. Worth 30 minutes?
