Crossrate Markets wires Robinhood Chain launches into a live FX quote desk—Launcher fires → TokenLaunched → token / creator / quoteToken (AED/EUR/CNY…) / poolId / taxBps land as open cards; liquidity hits the permanent locker, rate hook splits trade fees. PONS one-pad converge watches dominance-era opens; Bucket launchpad watches payout routing; CompanyPad company markets watches the company-metric registry; HARMONIC agent watches the agent path. This post watches currency-denominated opens + FX quoteToken. Product: crossrate.market (/contracts + /api/market live).

FAQ
Which contract emits Crossrate launches?
The Crossrate Launcher 0xfAD915358508fB5e826e807cAC5294c4233aEde5 on Robinhood Chain (chainId = 0x1237, 4663) emits TokenLaunched for each new coin. Supporting contracts (from crossrate.market/contracts, confirmed by the Launcher's own getters): coin factory 0xb8F540bdC1b0A49A9754dE6656fD0082B6fC3CA3, rate hook 0x28EB3bEF14323EffC99D066c9cB4309198b0A0cc, liquidity locker 0x21Fa7eaF03d80Be670C77aA50dcC348B9774C879. Launches before block ~62.43M came from earlier Launchers, e.g. 0x9Ec62caaEDE8Ee54fa1B8BF4747B0bAA523bD5C2 and 0x5108Ecc10B297d32B83e8b422F432Fe435cBdDBd.
What is the Crossrate TokenLaunched topic0?
topic0 = 0xe0809b2ad8aaf52f5807c111a464b3be723a8bad83656da180797a3ecca26a15, i.e. TokenLaunched(address,address,address,bytes32,uint16,uint256,uint128). It is the same on the current and earlier Launchers. topics[1..3] = token · creator · quoteToken; data = poolId · taxBps · supply · liquidity.
How do I tell whether a launch is quoted in AED, EUR or CNY?
Read quoteToken from topics[3] and map it to the Crossrate currency desk (quote contracts listed on crossrate.market /contracts). The radar card shows the mapped currency next to token, creator, poolId and taxBps.
Do I need an API key to run the radar?
No. demos1 Crossrate runs in the browser on the public WSS wss://robinhood-mainnet-rpc.blockreq.com/v1/rpc/public. For long-running use, swap the trailing public for your {API_KEY}. Register at blockreq.com for 3M free requests monthly.
