Frontend plasma transfers

[nicholasmueller]

Issue/Task: 990

Overview

Send transaction on plasma from internal wallet to any external address
Deposit to plasma from a cold wallet

Usage

run elixir-omg and set OMISEGO_CONTRACT_ADDRESS in eth_omisego_adapter in elixir and plasmaContractAddress in frontend /src/omg-plasma/config.js

For internal => external on plasma

• make sure you have plasma balance in hot wallet
• make sure an internal primary wallet has a blockchain deposit address with a balance
• wallets page -> primary wallet -> external transfer button -> select token and option to transfer on plasma
• you can see it working by sending to a registered cold wallet and the plasma balance should increase (blockchain wallets -> cold wallet detail)

For cold wallet => deposit to plasma

• make sure cold wallet has balance
• transfer -> select "to OmiseGO Network" -> confirm in metamask -> wait
• omg-js doesnt support callbacks during the lifecycle of the transaction so i shortcut the usual transfer flow (with pending and confirmed states)

Note that this is purely code review. Didn't try running.

Shouldn't we get this from some config somehow?

[jarindr]

this should be replaced with the blockchain config that is setup on backend @T-Dnzt

@T-Dnzt can i merge this and make new pr implementing O's blockchain settings?
