# RenTON
## Kherson Underground team's submission for Telegram Hack-a-TON #1
Bicycle/e-scooter rental prototype that processes transactions in TON TestNet blockchain.
The working prototype can be found [here](https://web-renton.herokuapp.com/) (https://web-renton.herokuapp.com/).
### Functional [Payment Channel service](https://github.com/devils2ndself/kherson-underground/blob/main/chariton-api/services/tonService.js)
- Workflow:
- Define a Service class instance.
- Call `initWallets()` to initialize the user and the system wallets for payment channels and remember them - _only done once per runtime_.
- Now we can work with payment channels and off-chain transactions as many time as we want - _however, only 1 contract at a given moment per service instance_.
- Call `startChannel()` method to deploy the channel, top up channel wallet balances (deposits), and initialize the channel.
This can be done as many times as we want in runtime; however it will not start a new channel if an active channel already exists.
- `pay(amount)` will perform an off-chain transfer from the User's wallet balance to the System's balance inside the payment channel.
Can be called as many times as possible until the channel is closed.
- Calling `closeChannel()` will close the payment channel and push it to the blockchain, distributing the funds between the two wallets.
Will reject if there is no active payment channel in service instance.
- The two TestNet wallets' addresses that we were using are `EQDGi47qkbNPyUCctuhzkbNfVfTCvWf-2CvNUbEpfB6ru9Up` (user) and `EQAKU7BeY8nGhFvYWjbVuFUEXAGweQEroUzENxSQjyBtVEgH` (system).
- The active payment channel will have a new id and address each time one is started.
### A couple of other notes:
- The rent price for transportation is stored in USDT, being converted to TON via CoinMarketCap API.
- Putting payment channels to hosting had it's own challenges of maximum transactions limits, so we made a decision of not uploading it to the production, but it works great in local environment.
- ChariTON was our previous idea and we couldn't rename the main folders at that stage.
