Improve burner-wallet development by using test or local networks

[TimDaub]

Scope

• Currently the burner-wallet is using clevis, ganache-cli and startLocalRelay.sh to orchestrate a local network for developers.
• This poses some problems, namely:
  • the xDai network is not simulated. Instead ganache-cli is used and ETH is sent around. Not xdai
  • Uniswap contracts are not deployed to the local network so Exchange.js won't work fully (ETH/DAI)
  • DAI/xDai won't work as there's no bridge contract available and as all the three tokens (ETH, DAI, xDai) are running on ganache-cli
• For development with LeapDAO's network, similar problems arise. For the past month, we simply used their public testnet and Rinkeby for testing hence. It worked well with some exceptions.
• Uniswap requires liquidity and arbitrage to allow proper token swaps. Uniswap has however an instance of their factory deployed on Rinkeby: https://docs.uniswap.io/frontend-integration/connect-to-uniswap#factory-address
• In an ideal world, we'd work on making everything work local. For now however, that seems to be way too much work. I'm hence proposing the following deliverables.
• I haven't done much research, but it doesn't seem like POANetwork has a xDAI testnet. I'd be happy to be proven wrong.

Deliverables

• Create a "test mode" burner-wallet for local development where the maximum amount of functionality is testable by using test and local networks
• Make sure that these test or local networks are easily ochestrateable by a developer. It shouldn't be more difficult than doing e.g. npm run start
• Debugging the various components should still be possible effortless. Make sure that you're allowing the debugging of smart contracts as well as UI and network code

Here's a few paths I could see this happen. It's the workers job to deliver on the most promising path. If there's a path that I'm missing, feel free to pursue that one too! Here they are:

(1) Stay with the current configuration (ganache-cli for xDai and ETH/DAI) but improve it by:

• adding Uniswap contracts
• making it easier to orchestrate. e.g. Simply doing npm run start
• Consider please that going this way, we'll still have a problem testing on LeapDAO's chain

(2) Talk to someone from POANetwork and ask them about an xDai test network. Use Rinkeby as the Rootchain + Rinkeby Uniswap contracts

(3) [Please feel free to explore other paths, but update us in the comments]
