How Swap Routing Works on Robinhood Chain
Routing on Robinhood Chain (chain ID 4663) is the process by which a swap app selects a sequence of Uniswap v4 pools to move your input token into the output token you asked for. When a direct pool exists and is deep enough, the route is a single hop; when it does not, the router splits the trade across multiple hops, potentially multiple pools per hop, to find a better net output.
Because the pool set and the liquidity in each pool change block by block, the same trade can take a different route at different times. A route is a suggestion computed from a snapshot of on-chain state; it is not a promise, and each app's router can pick a different path.

Single-hop vs multi-hop
A single-hop route swaps directly between the two tokens in one pool. A multi-hop route passes through an intermediate token (frequently a stable or wrapped ETH) because that path leaves the trader with more of the output after fees and impact. Neither is inherently better — the correct answer is whichever wins on net output at that block.
Why the route can shift
Between the moment you preview and the moment your transaction is included, another swap may have added or removed liquidity from a pool on the route. The router either re-quotes on submission or accepts a worse fill within your slippage tolerance; either way, the printed route is a snapshot, not a guarantee.
Limitations
Routing quality depends on the pool set the specific app knows about. Two apps can route the same trade differently because they index different pools or apply different weighting; neither is universally correct.
Frequently asked questions
Why did my swap route through an extra token? The direct pool was too thin or too expensive for your size at that moment, so a multi-hop path via an intermediate token produced more output after fees and price impact. Do all apps use the same router? No. Different apps may deploy or integrate different routers, index different pools, and use different weighting logic, so the route and even the executable output can differ per app. Can I force a specific route? Some apps expose route selection; others do not. If an app lets you pin a route, that route is only better when its pools remain the deepest by the time your transaction is included.
