IndexFactory

contracts/src/index/IndexFactory.sol — the permissionless launchpad. One immutable singleton per chain; anyone can call createIndex.

createIndex

function createIndex(IndexConfig calldata cfg)
    external payable
    returns (address token, address treasury);

Atomically:

1. Checks the registry isn't paused and the protocol treasury is wired.
2. Requires msg.value ≥ FeeRegistry.launchFeeWei (InsufficientLaunchFee).
3. Overwrites cfg.creator with msg.sender — creatorship can't be spoofed.
4. Clones the immutable IndexToken implementation (EIP-1167) and deploys a fresh IndexTreasury(reserveAsset, token).
5. Calls token.initialize(...), which validates everything and mints supply (1% protocol / 99% creator).
6. Forwards the launch fee to the protocol treasury and emits IndexCreated.

IndexConfig

struct IndexConfig {
    string  name;
    string  symbol;
    address creator;          // always overwritten with msg.sender
    uint256 totalSupply_;
    uint16  buyFeeBps;        // ≤ 1000, immutable
    uint16  sellFeeBps;       // ≤ 1000, immutable
    address[] stocks;         // 1..16, allow-listed, no duplicates
    uint8   distributionMode; // reserved (0)
    uint16  rfvShareBps;      // 0..9000, immutable
}

Function	Returns
allTokens(uint256) / allTokensLength()	Every index ever launched
isIndex(address)	Whether an address is an IndexPad token
treasuryOf(address)	The RFV treasury bound to an index
tokensByCreator(address)	Indexes launched by a creator

IndexCreated event

event IndexCreated(
    address indexed token,
    address indexed creator,
    address treasury,
    string  name,
    string  symbol,
    uint256 totalSupply,
    uint16  buyFeeBps,
    uint16  sellFeeBps,
    address[] stocks,
    uint8   distributionMode,
    uint16  rfvShareBps
);

This is the discovery root for the indexer — every clone is picked up from here (Ponder factory pattern), so newly launched indexes appear in the app automatically.
