That brings us to the end of this chapter. This chapter should help you design complex currency asset exchanges and market makers on the Stellar payments network. You can run this on a private blockchain network or on a public instance of the Stellar network. It's a great tool to inboard traditional market makers to blockchain payment networks.

We started this chapter by looking at Stellar's distributed exchange and the concept of market makers. We set up a private Stellar network instance with Horizon and Stellar Core. We then created user accounts for trading and issuing assets. We created three trading assets—namely, US Dollar (USD), Pound (GBP), and Euro (EUR)—and funded our trading account with these assets. Lastly, we created our currency exchange on top of the private Stellar network and ran the entire currency exchange end to end. 

The main takeaway from this chapter is understanding how we could onboard market makers to blockchain payment networks and build currency trading exchanges using blockchain. Such systems remove the need to trust a third party for executing cross-currency remittances and provide faster, more efficient payments.

In the next chapter, we'll see what is on the horizon for fintech applications for blockchain, and how we see the technology evolving to serve the domain better.
