Function Execute

core/vm/runtime/runtime.go:89–116

Execute executes the code using the input as call data during the execution. It returns the EVM's return value, the new state and an error if it failed. Executes sets up a in memory, temporarily, environment for the execution of the given code. It makes sure that it's restored to it's original stat
