cargo run -p solver -- --orderbook-url
INFURA_KEYentry should be replaced with the key associated with our Infura account.
cow-dex-ag-solver-urlis just a placeholder flag that indicates where the http solver (i.e., a custom solver) receives requests (which, in our case, will be a localhost server whose IP address is the standard 127.0.0.1), and the
CowDexAgis just a dummy name for the solver we will use. These should not be edited!
