Go to Accounts > Asset Lending.
Select a currency you want to lend. In this example, we pick USD. Open the Loan Offers tab.
This is where you can make a loan offer. The table on the right shows a list of "free" loan offers available at the time, sorted from best (lowest interest) to worst (highest interest). You can use it as reference for your own Daily Interest Rate.
Fill out the fields on the left (Daily Interest Rate and Amount You Wish To Lend). In this example, we will put 0.035 for daily interest rate, and lend out $90.
Your loan offer has been created and now available for the taking. It is also displayed in the table on the right.
