# Swaps

convertByPath converts the token to any other token in the sovryn swap network by following a predefined conversion path and transfers the result tokens to a target account. Please note that either the source or target token address has to be WRBTC. If the source is not RBTC, the wrapper contract should already have been given allowance of the source token. The wrapping or unwrapping of WRBTC is handled the wrapper contract.
