Turns a quote from /deposit/quote into the unsigned transaction the user’s wallet signs and submits. If the source token needs an ERC-20 allowance, an approval transaction is returned too - sign it first.
Rheon never signs. Your client submits the transactions with the user’s wallet, on the source chain.

​
