 Every node has a built-in keystore. Clients create users on the keystore, which act as identities to be used when interacting with blockchains. A keystore exists at the node level, so if you create a user on a node it exists _only_ on that node. However, users may be imported and exported using this API.

 In [Create a Local Test Network](create-a-local-test-network.md), we showed you how to launch a 5 node local test network. Once you have a local network the next step is to fund an address so that you can begin creating transactions and interacting with smart-contracts.
 
-We'll show you how to leverage a pre-funded private key to access funds on the X-Chain, C-Chain and P-Chain. **NOTE** this same private key, `PrivateKey-ewoqjP7PxY4yr3iLTpLisriqt94hdyDFNgchSxGGztUrTXtNN`, can be used to sign txs locally using [AvalancheJS](../apis/avalanchejs/README.md). You don't need to import the key into the local keystore in order to access those funds. They are in the genesis vertex and block for each respective chain.

 The port in this tutorial uses 9650. Depending on how you start your local network, it could be different. If you are using Avalanche Network Runner, please check [here](./create-a-local-test-network.md#retrieve-all-nodes) to see how to retrieve the port numbers.
