Hey there, i have a similar problem.

while trying to connect to publish a smart contract to Rinkeby ( while using Web3.py, Infura and Remix ) i get the extra data error

i don't know how to deploy this middle-ware WITHOUT using geth. is it possible to avoid using geth ?

[akru]

Hello @SyedMuhamadYasir, unfortunately no, Rinkeby is geth-only network. But web3py has middleware hook to work with it.

Hello @SyedMuhamadYasir, unfortunately no, Rinkeby is geth-only network. But web3py has middleware hook to work with it.

i see.

can you please refer a step by step guide to me, which could help me hook the middleware to the web3.py ?

I am actually quite confused on how to approach the issue of connecting web3.py to Rinkeby.

i have installed Geth but i am at a loss on how to use the Rinkeby network through geth, while using web3.py as a rough front-end to make calls to the smart contract. ( i'm not sure my machine can handle the load of being a full node )

any help or guidance you can provide is much appreiciated @akru !

@SyedMuhamadYasir, you can see how to use this hook in project sources:
