# TON Speedrun
## ๐ฉ Challenge 2: Chatbot Contract
๐ซ ะกompile, test and deploy chatbot smart contract to the test network. Getting Acquainted with the TON Actor Model
๐ The final deliverable will be pipeline for smart contract development.
๐ฌ Meet other builders working in TON and get help in the [official dev chat](https://t.me/tondev_eng) or [TON learn tg](https://t.me/ton_learn)

# Checkpoint 1: ๐ป Chatbot Smart Contract ๐
Here is a project on `ton/sandbox`, let's look at the smart contract, go to the folder `contracts` and file `chatbot.fc`
#include "imports/stdlib.fc";
() recv_internal(int msg_value, cell in_msg, slice in_msg_body) impure {
;; if you send over 0.001 TON to this contract, it will reply you "doge"!
;; ignore the sender if they send in less than 0.001 TON - needed for fee
;; to send the reply message
if (msg_value < 10000000) {
return ();
}
;; parse the in_msg cell to get the info we want
slice cs = in_msg.begin_parse(); ;; turn in_msg into a slice
int flags = cs~load_uint(4); ;; load the flags. we don't need this tho
slice sender_address = cs~load_msg_addr(); ;; load the sender address
slice msg_text = "reply"; ;; "doge" will be our reply comment
;; build the message cell that we want this contract to send back
;; see https://ton.org/docs/develop/smart-contracts/messages
cell msg = begin_cell()
.store_uint(0x18, 6)
.store_slice(sender_address) ;; reply back to the original sender
.store_coins(100) ;; send 100 nanoton so it's not a zero-value transaction which wallets may ignore
.store_uint(0, 1 + 4 + 4 + 64 + 32 + 1 + 1)
.store_uint(0, 32) ;; call op == 0 because we are not calling an op
.store_slice(msg_text) ;; store "doge" as a comment
.end_cell();
;; send the message https://ton.org/docs/develop/func/stdlib/#send_raw_message
send_raw_message(msg, 3);
}
This smart contract, upon receiving a message with a TON value greater than 0.001, sends back a message with 'reply' message. To deploy a smart contract to the test network, you need to:
- bring him to hexBoC form
- send a message to the network for deployment
---
# Checkpoint 2: ๐ฟ Compile hexBoC ๐จ
A cell represents a data structure on TON Blockchain. Bag of Cells (BoC) is a format for serializing cells into byte arrays. For the easement of working with a smart contract, we first convert it into a hex representation BoC,and then we use it as it is convenient for us in tests, deployment, etc.
Compile the smart contract with the command:
```sh
yarn compile
```
hexBoc can be viewed in `build` folder.
---
# Checkpoint 3: ๐พ Tests ๐ต
Before deploying a contract, itโs worth running it through tests, itโs just for this that itโs to use `ton/sandbox`. Sample test is in the folder `tests`. Run it with command:
```sh
yarn test
```
Make sure all test is colored green.
---
# Checkpoint 4: ๐ Deploy ๐
It's time to deploy, to do this, run the command:
```sh
yarn deploy
```
Scan the QR code with the Tonkeeper and confirm the transaction in the application.
Below the QR code there is a link to the blockchain explorer with your smart contract, save it.
For Example:
---
# Checkpoint 5: ๐ฎ Send Message to Your Chatbot ๐ฎ
Now let's test our smart contract directly on the testnet. For your ease, I have prepared a script that will allow you to quickly send a transaction:
```sh
yarn send
```
Scan the QR code with the Tonkeeper and confirm the transaction in the application.
Below the QR code there is a link to the blockchain explorer with your smart contract, in the next step we need this link.
---
# Checkpoint 6: ๐ Check your Dialog ๐
Open the explorer link you saved earlier and see if the chatbot responded to you:
Congratulations, you have compiled, tested and deployed a smart contract in the TON testnet!

# โ๏ธ Side Quests
Quick results are great, but to play longer, enjoy the ecosystem, I suggest you the following tutorials:
- Let's analyze the [smart contract](https://github.com/romanovichim/TonFunClessons_Eng/blob/main/lessons/pipeline/chatbot.md) of the chatbot
- Learn how to write [tests](https://github.com/romanovichim/TonFunClessons_Eng/blob/main/lessons/pipeline/chatbottest.md) for smart contracts that send messages
