ChainBridge

ChainBridge

This is a go implementation of a generic bridge between blockchains. The bridge will be able to connect any networks using native fuel or any token.

todo

• implement support for non EVM based blockchains

requirements

go 1.9.1

go-ethereum go get github.com/ethereum/go-ethereum

solc/solcjs npm i -g solc

to get the bridge

go get github.com/ChainSafe/ChainBridge

compile abi

cd solidity
mkdir build
solcjs --abi contracts/Bridge.sol -o build

to run

generic instructions for bridge, needs to be updated!

cd $GOPATH/src/github.com/ChainSafe/ChainBridge
go build && go install

ChainBridge [networks]

the arguments after ChainBridge are the names of the networks you want to listen on as specified in config.json

eg. ChainBridge ropsten kovan

• 1: mainnet

• 3: ropsten

• 4: rinkeby

• 42: kovan

• 31: rootstock testnet

  additional flags: ChainBridge -a [networks]

ChainBridge --config ./config.json [networks]

-a read logs from every contract on the network (not really useful, mostly for testing)

-v verbose output

--config specify path to config file

--keystore specify path to keystore file

interacting with the contract

for all the following, you should have another terminal open running the bridge listener with ChainBridge [networks]

ChainBridge fund network this will open up a prompt for you to make a deposit on the specified chain

ChainBridge deposit network this will open up a prompt for you to make a deposit on the specified chain id

ChainBridge pay network pay the bridge contract for a later withdraw on the specified chain

ChainBridge withdraw network this will withdraw ether that was paid to the bridge contract previously

--keystore specify path to keystore directory

--password specify password to account; this assumes that there's the same account for every chain

eg. ChainBridge fund kovan
