# Fee Model

Berachain:\
\
Ooga Booga only charges a fee if both Bex and Kodiak’s quotes are beaten. See image below:

Put simply, a quote is pulled from Bex, a quote is pulled from Kodiak, and then a quote is pulled from Ooga Booga. If Ooga Booga is able to beat both Bex’s and Kodiak’s price by at least 0.15%, a 0.069% fee is charged on the output token. This guarantees a betterment of at least 0.081% to the swapper if a fee is charged. \
\
This model is better than charging a blanket flat fee on the aggregator, which defeats the entire thesis of “finding the best price”.\
\
HyperEVM:\
\
Ooga Booga currently does not charge a fee, and only takes in positive slippage.
