+### Nym mixnet cosmos tx broadcaster demo 
+A demo showing how to: 
+* sign a cosmos tx (simple token transfer) offline 
+* broadcast this tx from a service on the other side of the mixnet
+
+For the moment the fact its a token transfer is hardcoded. This code could be built out to allow for queries, custom txs, wasm contract interaction, etc but goes beyond the bounds of this demo. 
+
+Built using: 
+* rust sdk 
+* validator client libs (that will soon be part of the sdk)
+
+#### Useage 
+```
+# compile
+cargo build --release
+
+example 1: sign & send in one go 
+# start service
+../../target/release/service
+
+# copy service's nym address to use as value of <SERVICE_NYM_ADDRESS> 
+
+# sign tx - when prompted enter 'y' 
+../../target/release/client offline-sign-tx ${SENDER_MNEMONIC} <RECIPIENT_NYX_ADDRESS> <SERVICE_NYM_ADDRESS>
+
+example 2: create signed tx 
+# start service

+
+# sign tx - when prompted enter 'n' and copy encoded tx bytes from terminal 
+../../target/release/client offline-sign-tx ${SENDER_MNEMONIC} <RECIPIENT_NYX_ADDRESS> <SERVICE_NYM_ADDRESS>

+### SDK support
 If your app is written in Typescript or Rust, then you can use the [Typescript](https://nymtech.net/docs/sdk/typescript.html) or [Rust](https://nymtech.net/docs/sdk/rust.html) SDKs. These SDKs abstract away much of the messaging logic from your app, and allow you to run a Nym client as part of your application process, instead of having to run them seperately.

 ### Choosing a client
-In order to connect your application to the mixnet, you need to select one of three clients to use. These clients do the majority of the heavy-lifting with regards to cryptographic operations and routing under the hood, and all do basically the same thing: create a connection to a gateway, encrypt and decrypt packets sent to and received from the mixnet, and send cover traffic to hide the flow of actual app traffic from observers.

-* If you're running a purely P2P application, then just integrating clients and having some method of sharing addresses should be enough to route your traffic through the mixnet. 
-* If you're wanting to place the mixnet between your users' application instances and a server-based backend, you can use the [network requester](https://nymtech.net/docs/nodes/network-requester-setup.html) service provider binary to proxy these requests to your application backend, with the mixnet 'between' the user and your service, in order to prevent metadata leakage being broadcast to the internet.

 Let's say your code code pokes a message `hello world` into the Nym client. The Nym client automatically wraps that message up into a layer encrypted Sphinx packet, adds some routing information and encryption, and sends it to its own gateway. The gateway strips the first layer of encryption, ending up with the address of the first mixnode it should forward to, and a Sphinx packet.

 The process for sending messages to other apps is exactly the same, you simply specify a different recipient address. Address discovery happens outside the Nym system: in the case of a Service Provider app, the service provider has presumably advertised its own address. If you're sending to a friend of yours, you'll need to get a hold of their address out of band, maybe through a private messaging app such as Signal.

+use nym_validator_client::nyxd::Coin; 
+```
+
+As well as importing message-handling functionality, request types, and the default RPC endpoint, this file relies on the `AccountId` type to construct blockchain addresses, the `MixnetClient` for interacting with the mixnet, the `Recipient` type to construct mixnet recipient addresses, and the `Coin` type for properly handling the returned balance of the account that will be queried.  
+
+# Querying via the Mixnet
+The following is used to construct a `BalanceRequest`, send this to the supplied `service` address, and then handle the response, matching it to a `ResponseType` (in this case the only expected response, a `BalanceResponse`).
+
+The actual sending of the request is performed by `client.send_bytes`: sending the serialised `BalanceRequest` to the supplied Nym address (the `Recipient` imported from the `nym_sphinx_addressing` crate). It is sending the default number of SURBs along with the message, defined [here](https://github.com/nymtech/nym/blob/develop/sdk/rust/nym-sdk/src/mixnet/client.rs#L34).

+# Preparing Your Client
+
+Start by creating the startup logic of your `client` in `bin/client.rs` - creating a Nym client and connecting to the mixnet (or just connecting if your client has been started before and config already exists for it), and defining and running commands.
+
+## Dependencies
+Import the following dependencies:
+```
+use clap::{Args, Parser, Subcommand};
+use chain_query::{client::query_balance, create_client};
+use nym_sdk::mixnet::Recipient;
+use nym_validator_client::nyxd::AccountId;
+use nym_bin_common::logging::setup_logging;
+```
+
+`clap` is used so different commands can be passed to the `client` (even though we're only defining one function in this first part of the tutorial, more will be added in subsequent chapters). `nym_sdk::mixnet::Recipient` is the type used to define the recipient of a mixnet message, `nym_bin_common::logging::setup_logging` is the logging setup for `client`'s Nym client, and `chain_query` imports the `create_client` and `query_balance` functions created on the previous page.
+
+## CLI Command with Clap
+The following simply defines the commands that the client can perform. For the  moment, there is only one: the `query_balance` function created in the previous section.
+
+As with the data structures, this structure is being used for ease of adding future commands in subsequent tutorials.
+
+```rust
+#[derive(Debug, Parser)]
+#[clap(name = "rust sdk demo - chain query service")]
+#[clap(about = "query the sandbox testnet blockchain via the mixnet... part 2 coming soon")]
+struct Cli {

+    account: AccountId,
+    /// the address of the broadcaster service - this submits txs and queries the chain on our behalf
+    sp_address: String,
+}
+```
+
+## `main()`
+This is the root logic of the `client`. Using `[tokio](https://tokio.rs/)` for the async runtime, this function performs the following functions:
+* If not already existing, create a Nym client with config at `/tmp/client`. Otherwise load the already existing client from this config.
+* Matche the command from the CLI - in this instance, the `QueryBalance` function which will be defined in the next section. This creates a `BalanceRequest` and sends this to the `service`, before returning the response back to the main thread and print this to the console.
+* Perform a proper shutdown of the Nym client.
+
+```rust
+#[tokio::main]
+async fn main() -> anyhow::Result<()> {
+    setup_logging();
+    let cli = Cli::parse();
+    let mut client = create_client("/tmp/client2".into()).await;

+# Interacting with a Cosmos SDK Blockchain via the Mixnet with the Rust SDK
+
+This tutorial is for Rust developers wanting to interact with the Rust SDK and take a first step at building a service with which to interact with a Cosmos SDK blockchain. 
+
+The key here is to think of the service as a proxy: it interacts with the blockchain _on the client's behalf_, shielding the client from the Validator it interacts with, whilst also being shielded from the client by the mixnet.
+
+> This service also nicely highlights the limitations of the mixnet - even though with this code your metadata is shielded from the Validator, and even the service does not know your Nym address, application-level information such as a blockchain address is not made private, in virtue of the fact that using the mixnet provides solely network-level privacy. For information on what application-level privacy Nym offers, check out the [coconut credential SDK example](https://nymtech.net/docs/sdk/rust.html#coconut-credential-generation).

+# Preparing Your Lib
+
+Now move on to preparing shared data structures and functions in `src/lib.rs`.
+
+These include the request and response types the client and the service will be passing through the mixnet, as well as shared functions such as client creation, and message parsing.
+
+## Dependencies
+The dependencies for the shared `lib` file are the following:
+```rust
+use anyhow::bail;
+use cosmrs::AccountId;
+use nym_sdk::mixnet::{
+    AnonymousSenderTag, MixnetClient, MixnetClientBuilder, ReconstructedMessage, StoragePaths,
+};
+use nym_validator_client::nyxd::Coin;
+use serde::{Deserialize, Serialize};
+use std::path::PathBuf;
+
+pub mod client;
+pub mod service;
+```
+
+Since this is the file where client creation and message parsing are handled, the various `nym_sdk` imports, as well as `serde`'s (de)serialisation functionality, are required. `PathBuf` is for reading filepaths, `cosmrs` types are required for defining Nyx blockchain accounts, and the `Coin` type from the `nyxd_validator_client` is for our Coin balance request and response. `anyhow` is for easy error handing.
+
+## Constants
+Below this are the chain-related `const` variables. These have been hardcoded for this demo.
+
+```rust
+pub const DEFAULT_VALIDATOR_RPC: &str = "https://sandbox-validator1.nymtech.net";
+pub const DEFAULT_DENOM: &str = "unym";
+pub const DEFAULT_PREFIX: &str = "n";
+```
+
+These define the RPC endpoint your service will use to interact with the blockchain - in this case the Sandbox testnet - as well as the expected coin denomination, and Bech32-prefix of addresses.
+
+## Shared Data Structures
+Define the following structs for our different request and responses that will be serialised and sent through the mixnet between your client and service binaries:
+
+```rust
+#[derive(Debug, Deserialize, Serialize, PartialEq)]
+pub struct BalanceRequest {
+    pub validator: String,
+    pub account: AccountId,
+}
+
+#[derive(Debug, Deserialize, Serialize, PartialEq)]
+pub struct BalanceResponse {
+    pub balance: Coin,
+}
+
+#[derive(Debug, Deserialize, Serialize, PartialEq)]
+pub enum RequestTypes {
+    Balance(BalanceRequest),
+}
+
+impl RequestTypes {
+    pub fn serialize(&self) -> Vec<u8> {
+        serde_json::to_vec(self).expect("serde failure")
+    }
+
+    pub fn try_deserialize<M: AsRef<[u8]>>(raw: M) -> anyhow::Result<Self> {
+        serde_json::from_slice(raw.as_ref()).map_err(Into::into)
+    }
+}
+
+#[derive(Debug, Deserialize, Serialize, PartialEq)]
+pub enum ResponseTypes {
+    Balance(BalanceResponse),
+}
+
+impl ResponseTypes {
+    pub fn serialize(&self) -> Vec<u8> {
+        serde_json::to_vec(self).expect("serde failure")
+    }
+
+    pub fn try_deserialize<M: AsRef<[u8]>>(raw: M) -> anyhow::Result<Self> {
+        serde_json::from_slice(raw.as_ref()).map_err(Into::into)
+    }
+}
+```
+
+The above data types are pretty straightforward. Even though there are only one instance of a request type (sent from `client` -> mixnet -> `service`) and one of a response type (`service` -> mixnet -> `client`) so far, a pair of enums has been defined to contain additional response and request types that will be added in part 2 of this tutorial, when adding credential functionality.
+
+`BalanceRequest` will be used when requesting the service to query the token balance of the supplied address on the client's behalf. You can see the information that will be returned from the chain to the service, and from the service to the client, in `BalanceResponse`.
+
+Custom serialistion and deserialisation have been implemented for each enum for ease of future modification and testing.
+
+## Shared Functions
+Now to define functions shared by the `client` and `service` binaries.
+
+### Client Creation
+The following function is called on startup by each binary, with the `config_path` being a filepath for storing client config:
+
+```rust
+// create our client with specified path for key storage
+pub async fn create_client(config_path: PathBuf) -> MixnetClient {
+    let config_dir = config_path;
+    let storage_paths = StoragePaths::new_from_dir(&config_dir).unwrap();
+    let client = MixnetClientBuilder::new_with_default_storage(storage_paths)
+        .await
+        .unwrap()
+        .build()
+        .await
+        .unwrap();
+
+    client.connect_to_mixnet().await.unwrap()
+}
+```
+
+If no config files exist at the location designated by `config_path` (in this case `/tmp/service`) then the following files are generated: 
+
+```sh
+service
+├── ack_key.pem
+├── db.sqlite
+├── db.sqlite-shm
+├── db.sqlite-wal
+├── gateway_details.json
+├── gateway_shared.pem
+├── persistent_reply_store.sqlite
+├── private_encryption.pem
+├── private_identity.pem
+├── public_encryption.pem
+└── public_identity.pem
+
+1 directory, 11 files
+```
+
+> If keys and config already exist at this location, re-running this function **will not** overwrite them.
+
+### Listening for & Parsing Incoming messages
+Next to define two functions: one for listening _for_ messages from the mixnet (used by `service`), and one for handling a _response_ to a request (used by `client`).
+
+Both functions attempt to deserialise the vec of `ReconstructedMessages` that are reconstructed by the client from delivered Sphinx packets after decryption.
+
+`handle_request` performs one additional function - parsing the `sender_tag` from the incoming reconstructed message. This is the randomised alphanumeric string used to identify a bucket of _SURBs_ (Single Use Reply Blocks) that are sent along with any outgoing message by default. More information about them can be found [here](https://nymtech.net/docs/architecture/traffic-flow.html#private-replies-using-surbs) but all that is necessary to know for now is that these are pre-addressed packets that clients send out with their messages. Any reply to their message that is to be sent back to them back be written to the payload of these packets, but without the replying party being able to see the destination that the reply is being sent to. This allows for services to **anonymously reply to clients without being able to doxx them by knowing their Nym address**. 
+
+```rust
+pub fn handle_response(message: ReconstructedMessage) -> anyhow::Result<ResponseTypes> {
+    ResponseTypes::try_deserialize(message.message)
+}
+
+pub fn handle_request(
+    message: ReconstructedMessage,
+) -> anyhow::Result<(RequestTypes, Option<AnonymousSenderTag>)> {
+    let request = RequestTypes::try_deserialize(message.message)?;
+    Ok((request, message.sender_tag))
+}
+```
+
+Before moving on to the `client` and `service` code, one more function is needed. This allows for both binaries to parse empty incoming messages that they might receive. This is necessary as incoming SURBs, as well as requests for more SURBs, contain empty data fields.
+
+```rust
+pub async fn wait_for_non_empty_message(
+    client: &mut MixnetClient,
+) -> anyhow::Result<ReconstructedMessage> {
+    while let Some(mut new_message) = client.wait_for_messages().await {
+        if !new_message.is_empty() {
+            return Ok(new_message.pop().unwrap());
+        }
+    }
+
+    bail!("did not receive any non-empty message")
+}
+```

+# Tutorial Overview
+
+This tutorial involves writing two pieces of code in Rust:
+
+- A client side binary used to construct a blockchain query and send this query to a service, which will query the Cosmos SDK blockchain and then pass the response back to the client (bear in mind this principle works for all blockchains - we're just utilising the `cosmrs` library to interact with the Sandbox testnet blockchain in this tutorial). This query will be to query the balance of an account, in preparation for spending these tokens on a [bandwidth credential](https://nymtech.net/docs/bandwidth-credentials.html) in a subsequent tutorial.
+- A service which will listen out for requests from the mixnet, act on those requests, and anonymously reply to the client sending the requests.
+
+You will learn how to do the following with the Rust SDK:
+- Create clients with manual storage settings.
+- Parse incoming traffic from the mixnet and reply anonymously using [SURBs](https://nymtech.net/docs/architecture/traffic-flow.html#private-replies-using-surbs).
+
+> Services usually run on remote servers to assure reliable uptime and to unlink sender and receiver metadata. For demonstration purposes however, you will run both components on your local machine, looping messages through the mixnet to yourself.

+Notice that this tutorial attempts to use very few external libraries. This tutorial is not showing you how to build production-grade code, but **to understand how to connect and send messages to, as well as receive messages from, the mixnet.**
+
+```admonish note title="Sidenote: What is a Service / Service Provider?"
+'Service' or 'Service Provider' are catchall names used to refer to any type of app that can communicate with the mixnet via a Nym client - in this case, one embedded in its app process via the Rust SDK.
+
+The first SP to have been released is the [Network Requester](https://nymtech.net/docs/nodes/network-requester-setup.html) - a binary that receives a network request from the mixnet, performs that request (e.g. authenticating with a message server and receiving new messages for a user) and then passes the response back to the user who requested it anonymously, shielding their metadata from the message server.
+
+The SP you will build in this tutorial is far more simple than this, showing you how to approach building something that can:
+* connect to the mixnet,
+* listen for messages, and
+* perform some action with them - in this case, query a Cosmos SDK blockchain.
+
+However, once you see how easy it is to integrate with the mixnet for traffic transport, you will be able to build apps with real-world uses easily.

+serde_json = "1.0.91"
+anyhow = "1.0.72"

+
+These are non Nym-specific dependencies for the project. `clap` is for setting up the CLI commands, `cosmrs` for cosmos-specific types and functionality, `tokio` for the async/await environment, and `serde` for (de)serialisation. `anyhow` is for catch-all error handling. 
+
+* Next add Nym-specific dependencies. Since these libraries are not yet on [crates io](https://crates.io) then you need to import them from the Nym monorepo:
+```

+
+The `sphinx` dependencies are for packet- and address-related functionality, the `validator-client` for Nyx blockchain specific configs, `common` for client logging, and the `sdk` for SDK functionality: creating and managing client storage and connections, and sending and receiving messages to and from the mixnet.
+
+* Finally add the following underneath your `[dependencies]`:

+* `client` and `service` both start their Nym clients and log the address. `service` is listening for incoming messages from the mixnet. 
+* `client` sends a request to `service` using the supplied `n1...` address as the Nyx account to query the balance of, and the supplied Nym address to communicate with this instance of `service`. 
+* `service` queries the Sandbox testnet blockchain using the `broadcaster` http client. It then serialises the response and returns it using SURBs to the `client`.  
+
+All in all, quite simple. By using the service as a proxy, the client never interacts with the blockchain, thus is not revealing metadata to the operator of the Validator nor any entities monitoring its incoming and outgoing traffic. Furthermore, the client doesn't even need to share its Nym address with the service, as the service is able to reply via SURBs.  
+
+## Creating Sandbox Account 
+If you wish to create an account on Sandbox to use instead of the supplied account above, the easiest way is by building the `nym-cli` tool and using that to create one: 
+
+```sh 
+# start from the root of the nym monorepo
+cd tools/nym-cli
+# build 
+cargo build --release 
+# create account using Sandbox testnet environment 
+../../target/release/nym-cli --config-env-file ../../envs/sandbox.env account create
+```
+
+However, since this account is fresh, it won't have any tokens. Querying the balance will still work obviously, it will just return `0`. 
+
+## Get Tokens
+We're working on getting the faucet up and running again in preparation for part 2 of this tutorial: using the tokens you have privately checked the balance of to generate a [bandwidth credential](https://nymtech.net/docs/bandwidth-credentials.html). 
+
+If you wish to get testnet tokens already then feel free to ask in the [Dev channel](https://matrix.to/#/#dev:nymtech.chat) on Matrix.

+Now to define the logic of creating the `broadcaster` for interacting with the blockchain, and querying it in `src/service.rs`. 
+
+## Dependencies
+The following dependencies are for creating a client to interact with the blockchain, and deal with the returned `Coin` type in `BalanceResponse`. 
+
+```rust
+use crate::{BalanceResponse, DEFAULT_DENOM, DEFAULT_VALIDATOR_RPC};
+use cosmrs::rpc::HttpClient;
+use cosmrs::AccountId;
+use nym_validator_client::nyxd::{Coin, CosmWasmClient};
+```
+
+## Creating a `broadcaster` 
+The `broadcaster` is an `HttpClient` taken from `cosmrs`, created with the `DEFAULT_VALIDATOR_RPC` as its default endpoint. The service will use this to query the Sandbox testnet chain. 
+
+```rust
+pub async fn create_broadcaster() -> anyhow::Result<HttpClient> {
+    let broadcaster: HttpClient = HttpClient::new(DEFAULT_VALIDATOR_RPC)?;
+    Ok(broadcaster)
+}
+```
+
+## Querying the Chain 
+Now to write the logic for querying the chain, using the `broadcaster` created in the previous step to query for the balance of the `account` that the client sent via the mixnet in the `BalanceRequest`. This function returns a `BalanceResponse` containing a `Coin` type, denoting the `balance` and `denom` returned by `get_balance()`. 
+
+```rust
+pub async fn get_balance(
+    broadcaster: HttpClient,
+    account: AccountId,
+) -> anyhow::Result<BalanceResponse> {

+The `AnonymousSenderTag` type is used for SURBs.
+

+Also using tokio for the async runtime, `main` does the following:
+* Create a Nym client with config at `/tmp/service`, or load the existing client from this config directory.
+* Create a `broadcaster` - this is used by the service to interact with the blockchain, using the consts defined in `src/lib.rs` as chain config.
+* Listen out for incoming messages, and in much the same way as the `client`, handle and match the incoming request.
+* Using the `sender_tag`, anonymously reply to the `client` with the response from the blockchain **without having to know the client's Nym address**.

+# Telegram NymConnect Integration
+
+*This is a shortened version of a [Nym Community post](https://blog.nymtech.net/how-to-use-telegram-in-iraq-with-nymconnect-106a3b8dd050) written by Saliveja.*
+
+The purpose of the following manual is not to promote Telegram but so people can use it with the Nym mixnet if they wish to, should a situation ask for that. This privacy-enhances Telegram at the network level and allows users to access the application from locations like where the application was banned.  
+
+See also: [Element (Matrix) over the Nym mixnet](./matrix.md): private, decentralised and secure messaging.
+
+## Setup & Run
+
+Here’s how to configure Telegram with NymConnect:
+
+1. Download and install NymConnect ().**
+	For more releases, check out [Github](https://github.com/nymtech/nym/tags). NymConnect is available for Linux, Windows, and MacOS.
+	On Linux make sure NymConnect is executable. Opening a terminal in the same directory and run:
+	```sh
+	chmod +x ./<YOUR-NYM-CONNECT-VERSION>.AppImage
+	```    
+2. **Start NymConnect**
+	Telegram is added to NymConnect by default.
+3. **Click connect - the host and port will now be displayed.**
+4. **Click on host or port to copy** the value to the clipboard.
+5. **Open the Telegram proxy settings.**
+	Linux: Telegram -> Settings -> Advanced -> Connection type -> Use custom proxy
+	MacOS: Telegram -> Settings -> Advanced -> Data & Storage ->  Connection Type -> Use custom Proxy
+	Windows: Telegram -> Settings -> Data and Storage -> Use proxy
+6. **Add a proxy** with the Add proxy button.
+7. **Select SOCKS5** and make sure the port details are the same as those generated by NymConnect. Alternatively, follow this link: https://t.me/socks?server=127.0.0.1&port=1080
+8. **Save the proxy settings** in Telegram.
+9. **Telegram is now running through the Nym Mixnet and is privacy-enhanced!**
+	This allows you to connect from regions which blocked Telegram.
+10. Note if you remain idle on Telegram for a while you might lose connectivity and your messages might not get through via SOCKS5 proxy. If that happens reconnect your NymConnect and reset the proxy again.
+
+
+Follow this [video](https://youtu.be/quj8H2qeOwY?t=97) to see the steps on Telegram setup.
+<!---It's set to particular time as the NC setup part is outdated --->
+
+**Now your Telegram runs over NymConnect.**
+
+NymConnect is currently available for several applications and service providers. Support for more apps is on the way. For any bug reports or feedback please reach out to us on Telegram or our [Discord](http://discord.gg/nym) server.
