2. Event: TokenLaunched

Keep local JSON FACTORY + TOKEN_LAUNCHED_TOPIC0. One Base public WSS: primary StonkLauncher2 TokenLaunched; stack quote / pool / launchTick on the card. Optional secondary chips: TokenMetaSet · DevBuy.

Step A · Subscribe factory TokenLaunched

  "jsonrpc": "2.0", "id": 1, "method": "eth_subscribe",
  "params": ["logs", {
    "address": "0x4714f6EC81639Ca59EEBE634490a4d8671DCe7B4",

}

• topics[0]: TokenLaunched(address indexed token, uint256 indexed tokenId, address indexed creator, address quote, address pool, uint24 fee, int24 launchTick, uint256 totalSupply, address feeLocker)
• topics[1] = token · topics[2] = tokenId · topics[3] = creator
• data: quote · pool · fee · launchTick · totalSupply · feeLocker
• Write launchState[token], tag stonks-exchange

Field	Rule

Step B · Optional TokenMetaSet / DevBuy

• TokenMetaSet topic0 0xe955341eaabea23fe2bbd1074b7cce8c1b283cfb10fa0ae061f932c977ddbcd7 — stack onto the same token card as a meta chip
• DevBuy topic0 0x84d429ed8af1c9cfe8bb07b556e4120e976c9f4c9232a7f50a15d31d83e232a9 — DevBuy secondary chip on the open window

Step C · Open-card fields

Outbound card first: token · tokenId · creator · quote · pool · fee · launchTick · totalSupply · feeLocker · launchTx · blockNumber · ts. RPC / endpoint stays in a collapsed secondary rail.
