The state of the SymbolicMachine.

val get_xtz_balance : contract_id -> t -> xtz

get_xtz_balance c state returns the amount of mutez owned by c in state.

val get_tzbtc_balance : contract_id -> contract_id env -> t -> tzbtc

get_tzbtc_balance c env state returns the amount of TzBTC owned by c in state, according to the TzBTC contract.

val get_liquidity_balance : contract_id -> contract_id env -> t -> liquidity

get_liquidity_balance c env state returns the amount of liquidity token owned by c in state, according to the Liquidity contract.

val get_cpmm_total_liquidity : contract_id env -> t -> liquidity

get_cpmm_total_liquidity env state fetches the current amount of liquidity tokens distributed by the CPMM contract from the state state.

val predict_required_tzbtc_deposit : xtz -> contract_id env -> t -> tzbtc

predict_required_tzbtc_deposit xtz_deposit env state predicts the deposit in TzBTC which will be required by the CPMM contract when executing a step AddLiquidity with xtz_deposit from state.

val build : ?invariant:(contract_id env -> t -> bool) -> ?subsidy:xtz -> specs -> t * contract_id env

build specs computes (1) an initial state for the SymbolicMachine, and (2) the environment associated to this state.

The machine enforces the resulting state is consistent with the specs given as inputs, and raises an Assert_failure exception if it does not.

One can use the optional argument subsidy to set the subsidy amount to a given value (by default, we use the same as the main chain). Additionally, the invariant optional argument can be used to verify that a given invariant holds at the end of the initialization.

val step : ?invariant:(contract_id env -> t -> bool) -> contract_id step -> contract_id env -> t -> t

step s env state executes a single step s from state.

The invariant optional argument can be used to verify that a given invariant holds after each baked block.

val run : ?invariant:(contract_id env -> t -> bool) -> contract_id step list -> contract_id env -> t -> t

run steps env state executes a list of steps from state.

The invariant optional argument can be used to verify that a given invariant holds after each baked block.
