### Why Robinhood Chain?

Bush is building on Robinhood Chain because of the real-world assets (RWAs) that are already live on it. Robinhood Chain gives us direct access to tokenized stock RWAs at scale, and Bush's architecture is a natural fit for putting that liquidity to work.

Bush Weighted Pools behave like an automated index fund. Once a pool's target weights are set, every trade that passes through the pool nudges its balances back toward those weights. As traders buy and sell against the pool to capture arbitrage, the pool is continuously rebalanced without any manual intervention. This turns a Weighted Pool of RWAs into a self-rebalancing index:

* **Automatic rebalancing**: no need for a fund manager, keeper, or periodic rebalancing transaction. Arbitrage traders do the rebalancing work by trading the pool back to its target weights.
* **Fee capture**: unlike a traditional index fund, liquidity providers earn swap fees from the same trading activity that keeps the pool balanced, rather than paying management fees.
* **Custom exposure**: LPs can express a view on an index of RWAs (e.g. 40/40/20) rather than being limited to equal or fixed weightings.

For anyone who wants exposure to a basket of Robinhood Chain's RWAs, or who wants to hold a share of an index that maintains itself, a Bush Weighted Pool is a strong fit: it combines index-like exposure with automatic rebalancing and ongoing fee income for liquidity providers.
