Can you elaborate?
ODL is a product that uses a DLT (the XRPL) and a digital asset (XRP) to facilitate cross bolder transaction.
Instead of finding a bank or payment provider that hold the foreign currency you want to deliver somewhere and exchange it for you currency, this system converts you local currency to XRP send the XRP to the destination and sells it there for the local currency.
If you send money to the Philippines or Mexico you may have used it without knowing.
This is a real product, real people use it (without knowing that they do).
