LGTM, but there is a typo in your sign off. |

I think you have to check for IsChainNotReachableError here.

@matthiasgeihs Because, we explicitly inform the user by returning a named error when there are problems connecting with the blockchain node.
@ggwpez I have fixed this now.

I see. It seems a bit unclean that we introduce such specific error handling logic in so many places. We could add wrappers for the handful of functions that need this handling and then consistently use the wrappers, right? It's ok here, but it's something worth discussing in general, I think.

Yes the initial approach calls the error wrapping on the lowest level, where we also could have done it on the highest…
Its much more effort like this i think.

- Previously, ERC20 deposit transactions would not work when using ganache-cli node. Because ERC20 deposit involved two txs and both txs got the same nonce. - Now, track the nonce in contract backend for each account and use it to ensure no two transactions get the same nonce.

Fix is attempted using approach 1 suggested in #62.
