Hello @Thekthekthek !

I would really appreciate, already love your code btw, but I would love to understand it better and use it better :) good job bro

Thank you !! :)

I understand that some parts of this code may be a bit puzzling as this library is intended for developers already comfortable with not only all the blockchain basics and web3.py, but also with previous Uniswap routers. So, going through all these concepts would be out of scope here.
But, if you just need a code sample, maybe the integration tests will help ?

Having said that, I plan to write a tutorial on how to do a swap with this lib and uniswap-smart-path (though not sure when as I'm super busy). So, considering your request, I'll try to make it a bit more accessible.

Hello @Thekthekthek !
I've written this tutorial
Hopefully it will give you a better understanding on how to use the UR codec! :)

from uniswap-universal-router-decoder.

I would love to see a sample of transaction for a swap, for example :

"""

from uniswap_universal_router_decoder import FunctionRecipient, RouterCodec

codec = RouterCodec()

Permit signature

data, signable_message = codec.create_permit2_signable_message( "0x...", amount, # max = 2**160 - 1 (I don't get how to do this part for example) expiration, (same thing) nonce, # Permit2 nonce (same thing) spender, # UR deadline, (same thing) 1, # chain id )

Then you need to sign the message:

signed_message = acc.sign_message(signable_message) # where acc is your LocalAccount

Permit + v2 swap encoding

path = [token_in_address, token_out_address] encoded_data = ( codec .encode .chain() .permit2_permit(data, signed_message) ----Same goes for code below---- .v2_swap_exact_in(FunctionRecipient.SENDER, Wei(10**18), Wei(0), path)

    .build(deadline)

)

Then in your transaction dict:

transaction["data"] = encoded_data

you can now sign and send the transaction to the UR

How you can get Nonce of Permit2 auto?
