Serialization plays no role in the extraction result. Therefore, we define instances
using the opaque ascription of module types to speed up the extraction
Module DSInstancesOpaque : Dexter2CPMM.Dexter2Serializable := Dexter2CPMM.DSInstances.
Module DEX2Extract := Dexter2CPMM.Dexter2 DSInstancesOpaque Dexter2CPMM.NullAddressAxiom.

We redefine init for the same reasons as for the liquidity token
Definition init (setup : Setup) : result State Error :=
Ok {|
tokenPool := 0;
xtzPool := 0;
lqtTotal := setup.(lqtTotal_);
selfIsUpdatingTokenPool := false;
freezeBaker := false;
manager := setup.(manager_);
tokenAddress := setup.(tokenAddress_);
tokenId := setup.(tokenId_);
lqtAddress := null_address
|}.
Ok {|
tokenPool := 0;
xtzPool := 0;
lqtTotal := setup.(lqtTotal_);
selfIsUpdatingTokenPool := false;
freezeBaker := false;
manager := setup.(manager_);
tokenAddress := setup.(tokenAddress_);
tokenId := setup.(tokenId_);
lqtAddress := null_address
|}.
We prove that the "new" init function, which does not use chain and ctx,
is total and computes the same result as the contract's init
Lemma init_total_no_context_use chain ctx setup :
Dexter2CPMM.DEX2.init_cpmm chain ctx setup = init setup.
Proof. reflexivity. Qed.
Definition receive_ (chain : Chain)
(ctx : ContractCallContext)
(state : State)
(maybe_msg : option Dexter2CPMM.Msg)
: result (list ActionBody * State) Error :=
match DEX2Extract.receive_cpmm chain ctx state maybe_msg with
| Ok x => Ok (x.2, x.1)
| Err e => Err e
end.
