About RAH Swap
The English name is RAH Swap. The Persian name is صرافی راه. Both point at the same interface on rahswap.com.
What it is for
The product compares on-chain and aggregator quotes and settles the route whose calldata matches the pair, the amount, and the signer. A platform fee is taken from the input and is capped in the contract at 10%.
It is not a custodian, an exchange account, or a place that holds an order book of its own. The pools belong to the venues named on each route.
