Enter a size and watch it break across the pools on ROBINHOOD TESTNET — live, before you even connect.
You approve the router and nothing else. It holds your tokens for the length of one transaction and keeps no balance between calls.
The floor covers the whole route, not each leg. If the split cannot clear it, the transaction reverts and you keep your tokens.
ROBINHOOD TESTNET uses ETH for gas. Get testnet ETH from the faucet if your wallet shows no gas balance.
