# short script to highlight the diffences between the v1/v2 iterations of the quoter for uni v3 pools, as appears to be tripping many up.
# The updated quoter takes a tuple with the arguments in, and switches positions of two of the values, amountIn and fee.
# Here are examples calling each with their respective ABI.
