Asked to add nova.markets as a perp DEX. It turns out to be two things, and
only one of them is ours to measure today.

What Nova is

Hyperliquid builder code	0x3f950b0a5221048097057af9fd162c3cdf81e9dd
Its own venue	Arbitrum, 0x1410FA3F87F6A6ea221E5D2aB608C23005eC34f3
HIP-3 dex?	No

The Arbitrum contract's proxy bytecode is byte-identical to the Gains
Network diamond: same 2,227 bytes, same sha256, different EIP-1967
implementation slot. So that side is a gTrade white-label, not a new
architecture, which also means everything this repo already knows about
reading Gains applies to it. Its docs list one market trading, HYPE/USD, out
of 453 pair entries, USDC collateral, 1.1x to 200x.

Not a HIP-3 dex: {"type":"perpDexs"} returns ten names and none is Nova
(abcd, cash, flx, hyna, io, km, mkts, para, vntl, xyz).

Why the builder row rather than the perp cohort

	Nova	Gains diamond
USDC held by the contract	$1,590.90	$705,081.29

One market and no measurable open interest. Adding it to PERP_VENUES would
put a row of near-zeros on /perps, and its Hyperliquid flow is already what
bench 030 measures for 104 other frontends off the same public feed, so both
would count the same trades twice.

What it actually trades

Public fills bucket, checked day by day over 46 days on 2026-10-21. 17 days
return a file, the earliest 2026-09-25:

	lifetime	best day (2026-10-20)
fills	156	6
wallets	-	3
notional	$27,729	$15,086
builder fees	$9.71	$5.28

For scale, fomo on that same day: 13,476 fills, 1,126 wallets, $34.07M,
$14,930.

That is small, and it belongs anyway. Bench 030 publishes 104 rows of
which 44 sit under $10 a day and at least six read exactly $0.00 with
zero samples. The cohort policy is every known builder, measured, whatever
the number says. Nova lands mid-way through the small tail, not at the bottom.

What changed

• harnesses/hyperliquid-frontends/builders.json: a 105th entry, with
  valid_from: 2026-09-25 established by the day-by-day scan rather than by
  the first day I happened to probe.
• benchmarks/hyperliquid-frontends.yml: a provider block on the same seven
  queries as every other row. Provider count 104 → 105, and no editorial field
  on this spec asserts a cohort size, so there is no prose to follow.
• src/data/provider-registry.ts: url and description, so the product page
  has an official link.

Not included

• No logo. I will not invent an asset; 13 of the 104 existing builders
  have none either. Drop a file in public/logos/nova-markets.* and add the
  manifest line when you have one.
• The X handle is @novadotmarkets, the one the docs name. I first wrote a
  plausible-looking handle that does not exist, then checked.

Checks

pnpm validate 253 specs valid. tsc --noEmit clean. eslint 0 errors.
bun test 713 pass, 0 fail.

The row appears once the harness redeploys and picks up the new registry
entry; it reads $0.00 on any day Nova routes no attributed fills, which is 29
of the last 46.
