Set of artifacts to investigate behavior of parity-bridge

  • ./bridge.orig - artifacts taken and modified from original version of parity-bridge
  • ./erc20 - artifacts used to test ability of the bridge to work with ERC20 token

ERC20 token testing

The steps below assume that paths corrected in corresponding files.

The steps below were tested on with Parity 1.9.2 and web3.py 4.0.0b9

  1. run parity (start_PoA_home.sh and start_PoA_foreign.sh):
    • PoA_home* are for the left side of the bridge,
    • PoA_foreign* are for the right side of the bridge
    • bridge account for PoA_home: 0x842eb2142c5aa1260954f07aae39ddee1640c3a7
    • bridge account for PoA_foreign: 0xf3ee321df87781864f46f6464e764c2827fca73b
    • actor to deposit and withdraw on both sides: 0x37a30534da3d53aa1867adde26e114a3161b2b12
    • logs are gathered through screen facility, so look at screen.[0,1] files for logs
    • balances could be get by erc20/get_balance_home_ipc.py and erc20/get_balance_foreign_ipc.py
  2. run bridge by erc20/bridge/start_bridge.sh. Log verbosity could be configured in erc20/bridge/bridge_runner.sh. Logs are collected through screen facility, so look at the file screen.[0,1] for bridge logs.
  3. deploy ERC20 token by erc20/bridge/token/token_foreign.py. It works with bridge configuration and database files to get information about IPC channels, originator of transactions and the bridge contract.
  4. register ERC20 token in the bridge contract by erc20/bridge/contract/foreign_tokenreg.py
  5. deposit to HomeBridge contract by erc20/bridge/contract/home_deposit.py. Value of ether to deposit is chosen randomly.
  6. get balance of ERC20 token on the right side by erc20/bridge/token/token_balance.py
  7. withdraw tokens from tht token contract by erc20/bridge/token/token_withdraw.py. Value to withdraw is chosen randomly.
