WIP

This is a WIP project of a Token-based Plasma Cash Implementations. This implementations only support ERC712 tokens. This repo corresponds to the contracts and Ethereum-related file, in the 3-repo project.

API Side Chain - https://github.com/epord/Plasma-Cash-SideChain

Front End Client - https://github.com/epord/CryptoMons-client

Ethereum Contracts - https://github.com/epord/Plasma-Cash-RootChain

The main Contract is located at contracts/Core/RootChain.sol.

How to deploy

Requirements

You must have downloaded Truffle and Ganache-cli.

Steps

1. ganache-cli -p 7545 -i 5777 --gasLimit=0x1fffffffffffff --allowUnlimitedContractSize -e 1000000000. Runs Ganache on port 7545, localhost and network ID 5777. Add the gasLimit, allowUnlimitedContractSize to be able to deploy big contracts. If you dont want to change
2. npm i
3. truffle migrate

Test

You can use Remix and Metamask. You can also test it using our WIP client and API.

Using the client

Setup

1. Clone the Front-End Client
2. Clone the API Side Chain
3. After truffle migrate, copy json the files in build/contracts of CrytoMons, ValidatorManagerContract and RootChain into the Api's src/json folder (override)
4. Setup Metamask network (Add a custom RPC -> http://localhost:7545 network 5777)
5. Import an account to Metamask using ganache's provided privateKey

Run transactions

1. Follow the Readme in each project.
2. Open localhost:8080 to use the client, make sure the API is running

Using Remix

Setup

1. After truffle migrate, save the contract address of CryptoMon, RootChain and ValidatorManagerContract
2. Setup Metamask network (Add a custom RPC -> http://localhost:7545 network 5777) with one of the chain's private keys
3. Import an account to Metamask using ganache's provided privateKey

Run Transactions

1. Install truffle-flattener
2. run truffle-flattener contracts/Core/Rootchain.sol >> RootChainOut.sol
3. run truffle-flattener contracts/Core/CryptoMons.sol >> CryptoMonsOut.sol
4. Copy RootChainOut and CryptoMonsOut into Remix
5. Compile the contracts (use 0.5.2 compiler if you want to debug)
6. On the Deploy and Run Transactions tab, make sure to use Injected Web3 and select the network in Metamask
7. Select CryptoMons and Add At Address copying the contract's address
8. Select ValidatorManagerContract and Add At Address copying the contract's address
9. Select RootChain and Add At Address copying the contract's address
10. In the ValidatorManagerContract make sure to setToken of CryptMons contract to true
11. Buy a CryptMon paying 0.01 eth, and safeTransfer it to RootChain address
12. Your token is now deposited
