Summary

Brings the app side of Elysium to main. It was reviewed in #123, which merged into feat/elysium (its stacked base) after #122 had already landed, so it never reached main. Same commits, no changes: the tree equals a91f77a, and the diff against main is app/ only (37 files).

Adds Elysium (Kinetiq's Arbitrum Orbit L2 for Hyperliquid, chain 99901, gas paid in HYPE) to the site as a fourth chain, behind the existing "Coming soon" gate. Until NEXT_PUBLIC_LAUNCH_FACTORY_ELYSIUM is set, the form shows Elysium as "Coming soon", /elysium returns 404, and no switcher offers it. The contracts are already live on Elysium (block 3986599, #122), so switching on is configuration only.

• Chain: id 99901, HYPE as a plain 18-decimal native asset, public RPC fallback (ELYSIUM_RPC_URL overrides it on the server), Multicall3, explorer under elysium.kinetiq.xyz/explorer.
• Uniswap v4: addresses from deployments/99901.md. Universal Router v2.1.2 with the v2 swap layout, proven on a fork with a USDC pool.
• Quotes:
  • HYPE (native, the default) and USDC at a fixed dollar.
  • WHYPE is a known quote, priced at HYPE's price.
  • A new hype quote key carries HYPE's live price, filled on the server the way GITLAWB's is. hypePrice.ts reads Coinbase HYPE-USD first, falls back to Hyperliquid allMids, serves the last good value for at most 15 minutes, then reports null.
• Launch form: decides "native quote" by address(0) (isNativeQuote) instead of the eth key, so HYPE takes the native path: msg.value, no approvals, gas reserve taken from the same balance. Presets are in HYPE.
• Indexer: LAUNCH_DEPLOY_BLOCK_ELYSIUM; 2 confirmations, like Robinhood Chain (also Orbit); lag alert at 4,000 blocks (100 ms blocks).
• Env plumbing: .env.example, Dockerfile, fly.toml, fly-secrets.sh, and the dev RPC list in the CSP.
• Brand: public/brand/elysium.png is Elysium's mark as supplied by the maintainers (225×225 PNG, unchanged), used by the chain logos and the wallet menu. It is a black disc on white, so it reads on both themes. Swap in Kinetiq's brand-kit SVG when one is published.

Deliberately not in this PR

• Site-wide copy that lists the chains by hand: brand title and tagline, footer, hero, about, me, feed, rules intro, README. It comes with the switch-on, so the site never advertises a chain it can't launch on yet.
• The bridge dialog. Relay supports Elysium; that's a follow-up.

Test plan

• tsc --noEmit clean, npm run lint clean
• npm test: 1391 tests, 1380 pass, 11 skipped, 0 fail. New tests: hypePrice.test.ts; Elysium cases in native-quote.test.ts (HYPE is never priced as ETH; WHYPE shares HYPE's key; the HYPE SQL arm is chain-scoped). The chain-name branch guard now covers elysium and 99901.
• Production build with the Elysium factory set: /elysium is built
• Local smoke run with Elysium configured:
  • /elysium returns 200
  • the form offers HYPE and USDC, with HYPE's live price passed in
  • /api/rpc?chain=elysium answers chain id 0x1863d
• Switch-on: set NEXT_PUBLIC_LAUNCH_FACTORY_ELYSIUM / NEXT_PUBLIC_LAUNCH_LOCKER_ELYSIUM (build args), LAUNCH_DEPLOY_BLOCK_ELYSIUM=3986599 and ELYSIUM_RPC_URL (secrets); add the site copy

Summary by CodeRabbit

• New Features
  • Added Elysium support, including a dedicated landing page, network details, explorer links, and wallet branding.
  • Added token launches on Elysium with HYPE and USDC quote options, HYPE quick-buy amounts, and live HYPE price information.
  • Added HYPE volume to launch totals and included HYPE pricing in cross-chain sorting.
• Bug Fixes
  • Improved native-asset handling so launch costs, balances, and gas reserves work correctly across native quote assets.

Walkthrough

The change adds Elysium as a supported chain and launchpad option. It adds HYPE/USD price retrieval, HYPE quote handling, deployment settings, and Elysium-specific pages and interface details.

Changes: Elysium chain and HYPE launch support

Layer / File(s)	Summary
Register Elysium and runtime support app/src/lib/chainKeys.ts, app/src/lib/chainPublic.ts, app/src/lib/config.ts, app/src/lib/earn/*, app/src/lib/launchpad/indexer.ts, app/src/proxy.ts, app/.env.example, app/Dockerfile, app/fly.toml, app/scripts/fly-secrets.sh, related tests	The chain registry, public chain definition, RPC settings, and runtime configuration add Elysium. Related chain-list tests and deployment settings are updated.
Configure Elysium launch quotes and native handling app/src/lib/launchpad/config.ts, app/src/lib/launchpad/first-buy.ts, app/src/components/launchpad/LaunchForm.tsx, app/src/lib/launchpad/{gitlawb,twig,stocksServer,math}.ts, related tests	Elysium is configured with HYPE, WHYPE, and USDC quotes. The launch form and first-buy logic use native-quote address checks. Chain-specific launch settings and tests are added or updated.
Fetch and apply HYPE prices app/src/lib/launchpad/hypePrice.ts, app/src/lib/launchpad/hypePrice.test.ts, app/src/app/launch/page.tsx, app/src/lib/launchpad/{pairPrice,queries}.ts	A server-side helper retrieves HYPE/USD from Coinbase, falls back to Hyperliquid, and caches results. Launch-page loading, pair pricing, USD sorting, and HYPE volume totals use HYPE pricing or quote data.
Add Elysium pages and interface details app/src/app/elysium/page.tsx, app/src/app/rules/page.tsx, app/src/app/t/[chain]/[token]/page.tsx, app/src/lib/chainLanding.ts, app/src/components/WalletMenu.tsx, app/src/components/launchpad/{ChainBadge,ChainLogo}.tsx	Elysium landing-page metadata, contract-source links, wallet and launchpad marks, and chain-specific display copy are added.

Merge Risk: Low · up to ef538

If HYPE price services time out, the launch form can load about ten seconds late even when Elysium is unavailable. When HYPE is selected, the form incorrectly says buyers pay with ETH. Both are bounded issues to fix or accept before merging.

Minor · Functional Correctness · Quick win

Add HYPE copy to the "Priced in" helper text.

The helper text falls back to "Buyers pay with ETH." for any key other than usdg and usdc. When the user selects HYPE on Elysium, the form shows this wrong text. Add a branch for quote.key === "hype".

Proposed fix

-quote.key === "usdg" || quote.key === "usdc" ? `Buyers pay with ${quote.symbol}; market cap and fees are in dollars.` : "Buyers pay with ETH."
+quote.key === "usdg" || quote.key === "usdc" ? `Buyers pay with ${quote.symbol}; market cap and fees are in dollars.` : `Buyers pay with ${quote.symbol}.`

This line is outside the changed lines, but the PR makes it reachable for Elysium.

Update the page description to name Elysium.

The meta description still lists "Base, Robinhood Chain or Arc". Elysium is now a launch chain once configured. Use chainList() or add Elysium to the text.

Unverified finding
Verification ran but could not confirm this finding. It is shown for review, not as a verified issue.

Decide native quotes by address, not key, to match the rest of the PR.

suggestFirstBuy still uses i.quote.key === "eth" || i.quote.key === "hype". The PR moves the form to address-based isNativeQuote because WETH and WHYPE share these keys. SuggestInput.quote has no address, so a WETH or WHYPE quote would take the shared-balance path. The comment states the form never offers them, so the risk is latent. Add an optional native flag to SuggestInput, or pass address, and have LaunchForm supply isNativeQuote(quote).

Skip HYPE pricing when Elysium is unavailable.

If both HYPE sources time out on a cache miss, the launch form can remain loading for about ten seconds, even when Elysium is not configured. Keep the fetch when Elysium is configured or when no chains are configured for development.
