Chapter 4. Keys, Addresses, Wallets

I am using this package to generate the bitcoin key pairs. Remember that this tutorial is only to understand how we can implement a grpc server and client in the context of bitcoin. For production-level software, you may want to use another tool, such as the Blockcypher API or anything else. Anyway, when it comes to cryptocurrencies, you must be aware of the risk of managing assets on behalf of users.

First, we have the CreateWallet function that returns four strings , the bitcoin address, the public key, the private key, and the mnemonic phrase. Notice that we are not storing this data anywhere, so the user MUST write down and keep this information into a safe place since we cannot recover this data later. We are going to use a couple of packages here, make sure you install them in your project using:. Now we need to add our function to retrieve our wallet. The decode wallet function takes one argument, the mnemonic. Using the mnemonic we can decode our private and public keys.

Finally we are going to add a function to get our address balance:. Putting all together:. Once we have our wallet script is time to create our main script to implement our grpc server. This script has three functions, the same we have written in our wallet. We also are calling our wallet methods for these functions.

If you run this script with go run main.

In the next chapter we will see step by step how to implement a client for our grpc server. You can download the whole code here , this already includes a small CLI. To use it just run it as follows:. In the following chapter we are going step by step on how to implement this CLI. Happy hacking!
