Decision guide

What matters most before choosing in this category

Treat the upgrade key as the whole decision, because it is the only part that is an on-chain fact rather than a promise. Across the chains these vendors have launched, the multisig that can change the chain is frequently the vendor's own, and one Conduit multisig alone holds bridge-upgrade rights on eight live chains. Second, ask for a price before you ask for a demo: only Karnot, the smallest vendor here, publishes a mainnet monthly figure, and Conduit publishes a rate card — the rest price by conversation. Third, get the exit in writing. And weigh the operating record honestly: of the chains L2BEAT badges to this category, exactly half are archived, so the question is not whether a vendor can launch a chain but whether the ones it launched are still running.

Key question

Which multisig can upgrade your chain on day one, and whose signers are in it?

Key question

Can you get a price you can budget against without entering a sales cycle?

Key question

Is there a written key-handover procedure, and have you read it before deploying?

Starknet appchains on the Madara sequencer stack, with a published monthly mainnet price

Data checked Aug 2026

Starknet appchains on the Madara sequencer stack, with a published monthly mainnet price. Strongest on a price you can act on before you talk to sales (9/10): The only vendor in the pool that publishes a mainnet operating price on the page where you would buy: "$5000" "/ month" under MAINNET, beside a "Free" devnet/testnet tier, with the contents of each tier listed. No revenue share, no 'contact for pricing', no contradiction between pages (karnot.xyz/pricing returns HTTP… Weakest on chains still running, independently counted (3/10): Karnot carries an L2BEAT RaaS badge definition alongside the majors, but with exactly one badged chain — Paradex — which is live, giving a 1-of-1 survival record on a sample too small to be evidence of anything. status.karnot.xyz does not resolve (NXDOMAIN confirmed by dig, 2026-08-06) and no uptime number is… Published price: karnot.xyz (re-fetched 2026-08-06), pricing section, quoted exactly.

Main tradeoff

Karnot is the only vendor that tells you the price before the call — $5,000/month, above the $3,000/month implied by Conduit's own blog — but it is Starknet-only, has exactly one chain L2BEAT tracks, publishes no uptime measurement or status page, and makes no written commitment to hand you the keys. You are buying price transparency and clean on-chain custody on a sample of one, and taking the operating record on faith.

karnot.xyz (re-fetched 2026-08-06), pricing section, quoted exactly. DEVNET AND TESTNETS: "Free" / "For the tinkerers" — "Sequencer, Explorer, Bridge, Faucet, Dashboard". MAINNET: "$5000" "/ month" / "For growing teams" — "EVERYTHING IN TESTNET, PLUS: Automatic upgrades, High uptime, Detailed monitoring, On call support, Customisations". Normalised on 2026-08-06: $5,000/month x 12 = $60,000/year, all-in for the listed components, with no revenue share attached. The only other vendor-stated mainnet figure anywhere in this pool is Conduit's blog claim of "$36,000 per year" = $36,000 / 12 = $3,000/month, to which Conduit's live pricing page adds "+ 5% sequencer profit" — and that blog figure is contradicted by the same vendor's pricing page, which quotes every chain tier as "Contact for pricing". Karnot's $5,000/month is therefore the only mainnet monthly price in this pool published on the page where you would buy it. Both figures were re-fetched on the same day, 2026-08-06, so the comparison is same-date.

Frequently asked

Questions people ask before choosing raas

Who actually controls a chain launched through one of these vendors?

Read the upgrade multisig rather than the marketing, because it is public. Across the chains L2BEAT tracks for these vendors, the address able to upgrade the chain is often the vendor's own multisig rather than the team's, and a single Conduit multisig with a four-of-ten threshold appears across twenty-six tracked chains and holds bridge-upgrade rights on eight live ones. That is not necessarily wrong — an early team may genuinely want the vendor operating it — but it should be a decision you made rather than one you discover, and it is why custody carries the heaviest weight here.

Why do so few of these vendors publish a price?

Because the category sells to teams in a procurement cycle rather than to buyers reading a page. Karnot publishes a monthly mainnet figure on its homepage and Conduit publishes a rate card; every other vendor in this pool publishes no chain price at all. One caution the research turned up: a headline deposit figure on one vendor's page is a testnet deposit whose tokens the same page tells you to get free from a faucet, so a number being printed is not the same as a number you can budget against.

How likely is it that my chain outlives the vendor relationship?

Less likely than the category implies. Counting the chains L2BEAT badges to these vendors at a pinned repository commit and recounting them independently gives 44 live against 44 archived — exactly half the fleet is dead. Archived does not always mean failed; testnets and deliberate wind-downs are in there too. But it does mean the base rate for a launched chain still running is around one in two, which is the number to plan a migration path against rather than the vendor's launch count.
