+# Chapter 16: Programming with Libwally
+
+The previous chapter presented three C Libraries, for RPC, JSON, and ZMQ, all of which are intended to interact directly with `bitcoind`, just like you've been doing since the start. But, sometimes you might want to code without direct access to a `bitcoind`. This might be due to an offline client, or just because you want to keep some functionality internal to your C program. You also might want to get into deeper wallet functionality, like cryptography or address derivation. That's where Libwally comes in: it's a wallet library for C, C++, Java, NodeJS, or Python, with wrappers also available for other languages, such as Swift.
+
+This chapter touches upon the functionality possible within Libwally, most of which complements the work you've done through RPC access to `bitcoind`, but some of which replicates it. Obviously, this could be used with all three of the libraries from the previous chapter, and together they can create a strong basis for your C programming of Bitcoin.
+
+## Objectives for This Chapter
+
+After working through this chapter, a developer will be able to:
+
+   * Use Cryptographic Functions with Libwally
+   * Use Wallet Functions with Libwally
+   * Create C Programs that Integrate Multiple Functionality
+   
+Supporting objectives include the ability to:
