Solana has been working on the financial models and the protocol for years. Many of the RWAs and the protocols extended out of Ethereum over the years. And before the Ethereum got more hold of the market, Solana too expanded in the banking world. 

Now POC, Citi Bank and Solana tested a tokenization for the set of bill of exchange. Which is kind of common in the banking industry. 

The market is very high valued on the bill of exchange market around 10T USD. And they seem to be interested in getting the market cost and also the public ledger approach of the market with the blockchain. We are going to be seeing some really good changes in the banking as we add more blockchain components around the world. Solana would make things easier and simple too.
