bite-keeper's Issues
Should only bite when there is arbitrage opportunity
The mechanism of incentivising keepers to bite still doesn't exist.
Cannot successfully authenticate with remote Infura RPC endpoint
Description
bite-keeper cannot successfully connect to my Infura instance in order to interact via JSON-RPC.
To the best of my knowledge, all of the settings on my Infura endpoint are the defaults (i.e., no whitelists, etc.).
After inspecting the code in bite_keeper/bite_keeper.py, I modified line 44 to use https as the prefix, rather than the (existing) http prefix.
That is, this line:
bite-keeper/bite_keeper/bite_keeper.py
Line 44 in 43dbac8
becomes this:
elf.web3 = kwargs['web3'] if 'web3' in kwargs else Web3(HTTPProvider(endpoint_uri=f"https://{self.arguments.rpc_host}:{self.arguments.rpc_port}",
request_kwargs={"timeout": self.arguments.rpc_timeout}))Note: Yes, I have replaced both <eth addr> and <Infura public API key> fields with their correct values in all code snippets below.
