Long.xyz on Robinhood Chain (Doppler launches, contracts and API)

How Long.xyz launches tokens on Robinhood Chain through Doppler on Uniswap v4, its launcher and factory addresses, and how to list its tokens with Crius.

Updated 3 min read
Short answer

Long.xyz launches tokens through its launcher contracts and the shared Doppler Airlock straight onto Uniswap v4, so its tokens trade on a v4 pool for life (status: "launched", no bonding curve). List them with GET /v1/robinhood/tokens?launchpad=long, get stats with GET /v1/robinhood/launchpads/long, and one token's launch and pools with /token/{address}/launch.

GET /launchpads GET /tokens GET /token/{address}/launch

Long.xyz is a token launch platform whose tokens go straight onto Uniswap v4 through Doppler, the same shared launch protocol Bankr uses. There is no bonding curve and no graduation: a Long token’s v4 pool is its market from the first block. Of the launchpads Crius attributes, Long is second only to Pons by volume, and its tokens are paired with almost anything: ETH, USDG, tokenized stocks and other tokens, including PONS.

How a Long token launches

  1. Launch. Long’s factory calls the Doppler Airlock, which deploys the token and initializes its Uniswap v4 pool, and the factory emits LaunchCreated with the token (asset), the quote (numeraire), the pool or hook, the launcher and a normalized ticker. Crius attributes the token from that event.
  2. Trading. From the first block, buys and sells are ordinary v4 swaps, which Crius indexes like any other pool. List rows show status: "launched" and progress_pct: null.
  3. No migration. Doppler supports migrating a pool to a new market, and Crius listens for the Airlock’s Migrate event as Long’s graduation, but none has happened for a Long token. In practice a Long token keeps its v4 pool for life.

Because Long and Bankr share the Doppler Airlock, Crius attributes Long tokens from Long’s own LaunchCreated events, not from the Airlock alone. Every Long token in the samples on this page has an address ending in 1e18.

What this tells you

  • The Shiny Object (0xcc15dd17b92dc81a1580a516b2887d449b671e18) was created 35 seconds before the response, quoted in MSFT, with a logo and a link to a post on X.
  • It shows market_cap_usd: 19968.1 but liquidity_usd: 0 and no trades: the pool has a starting price but no quote currency in it yet. Agent Muse (0xa9a57fede9e6c859febd1b1f510d34d1d0d51e18, META) looks the same.
  • catcast (0xb110cb51b07fd237519ad1f90bc53170e0d61e18) has quote: null and market_cap_usd: null: no price yet at all.
  • All three: status: "launched", progress_pct: null, holders: 2.
Token lists reference Runs from your browser on the anonymous plan Data looks wrong? Report it

/token/{address}/launch (Free plan) returns a Long token’s factory, creator, quote token, launch transaction and block, status and its pools. For a token’s markets, prices and liquidity, use /token/{address}/pools.

Use it in your app

  1. Filter launches by liquidity. New Long tokens start with no quote-side liquidity; list=new&launchpad=long&min_liquidity_usd=1000 waits for the first real buyers.

  2. Rank the established tokens. Most Long volume is in a few large tokens: list=trending&launchpad=long or list=top_volume&launchpad=long.

  3. Handle unusual quotes. Pairs against PONS, HIMS or MSFT are normal here. Use price_usd and liquidity_usd, which Crius converts to USD through the quote’s own pools.

  4. Don’t wait for graduation. A Long token never moves; its pool on day one is its pool for good.

Frequently asked questions

How do I list Long.xyz tokens on Robinhood Chain?

Call GET https://api.crius.sh/v1/robinhood/tokens?list=new&launchpad=long for the newest, or list=top_volume&launchpad=long&window=24h for the most traded. Subscribe to launches:long on the WebSocket stream to get each launch as it happens.

Do Long.xyz tokens graduate?

No. They launch directly onto a Uniswap v4 pool and stay there. Doppler can migrate a pool in principle, and Crius watches the Airlock's Migrate event, but no Long token has migrated: graduated is 0 in the stats.

What are the Long.xyz contract addresses?

Long launches come from the LongLaunchFactory proxy 0x1eef016f22a943abc7dd11422edee9d235942104 and the earlier LongLauncher 0x22e99278308b393ea1260859b181ad7e78f5eeed, both through the Doppler Airlock 0xeb7c034704ef8dcd2d32324c1545f62fb4ad0862. GET /v1/robinhood/launchpads/long lists the two launchers under contracts.launch_contracts.

What do Long.xyz tokens trade against?

Anything: in the samples, Artificial Inu trades against PONS, Boner Coin against the HIMS stock token, A Meme Coin against AMC, and new launches against MSFT and META. Long's 24-hour volume was spread across stock tokens ($3.3 million), other tokens ($2.8 million), ETH ($2.4 million) and USDG ($2.3 million).
