+To create and send private transactions use one of:

+* [`eea_sendTransaction` with EthSigner](https://docs.ethsigner.pegasys.tech/en/latest/Using-EthSigner/Using-EthSigner/) 
+
+!!! note
+    Private transactions either deploy contracts or call contract functions. 
+    Ether transfer transactions cannot be private.

+# web3.js-eea Client Library
+
+The [web3.js-eea library](https://github.com/PegaSysEng/eeajs) adds an additional property to your web3 
+instance by extending [web3](https://github.com/ethereum/web3.js/). Use the library to create and send 
+RLP-encoded transactions using JSON-RPC.
+
+!!! note
+    web3.js-eea supports JSON-RPC over HTTP only. 
+
+## Prerequisites
+
+- [Node.js (version > 10)](https://nodejs.org/en/download/)  
+
+## Add web3.js-eea to Project 
+
+```bash
+npm install web3-eea
+```
+
+## Initialize EEA Client 
+
+Initilize your EEA client where: 
+
+* `<JSON-RPC HTTP endpoint>` is the JSON-RPC HTTP endpoint of your Pantheon node. Specified by the 
+[`--rpc-http-host`](../../Reference/Pantheon-CLI-Syntax.md#rpc-http-host) and [`--rpc-http-port`](../../Reference/Pantheon-CLI-Syntax.md#rpc-http-port) 
+command line options.
+* `<chain_id>` is the [chain ID](../../Configuring-Pantheon/NetworkID-And-ChainID.md) of your network. 
+
+!!! example
+    ```js tab="Syntax"
+    const EEAClient = require("web3-eea");
+    const web3 = new EEAClient(new Web3("<JSON-RPC HTTP endpoint>", <chain_id>);
+    ```
+    
+    ```js tab="Example"
+    const EEAClient = require("web3-eea");
+    const web3 = new EEAClient(new Web3("http://localhost:8545", 2018);
+    ```
+
+## Deploying a Contract with sendRawTransaction 
+
+To deploy a private contract, you need the contract binary. You can use [Solidity](https://solidity.readthedocs.io/en/develop/using-the-compiler.html)
+to get the contract binary. 
+
+!!! example "Deploying a Contract with sendRawTransaction"  
+    ```js
+    const contractOptions = {
+      data: `0x123`, // contract binary
+      privateFrom: "orionNode1PublicKey",
+      privateFor: ["orionNode3PublicKey"],
+      privateKey: "pantheonNode1PrivateKey"
+    };
+    return web3.eea.sendRawTransaction(contractOptions);
+    ```
+
+The transaction hash is returned. To get the private transaction receipt, use `web3.eea.getTransactionReceipt(txHash)`.
