Haven't seen it framed this way, but builder codes are hyperliquid:native version of user-generated content.
In gaming, platforms won by letting creators own the audience and share the upside. Builder codes do that for trading: if your app routes the order, you earn a cut.
The result is dozens of apps built on one liquidity layer, each monetizing a different slice of attention. Telegram bots, mobile front ends, wallets, copy trading. None of them needed a partnership or a license to plug in. That's UGC for permissionless finance.
