I want to pull a random integer value from the VRF beacon into my smart contract. I am writing in PyTeal, but can also use TEAL. I am looking for a simple call function in PyTeal or TEAL to the VRF beacon.
For example in Python:
random_int = Global.VRF() that I can use.
But, I do not think Global has a VRF method. So, I am looking for something similar.
Or in TEAL:
global RandomNumber

The short answer is no. There is no simple way to implement the VRF. It is extremely complicated to add VRF because you also need to commit to a specific round and actually generating the random result requires several other functions. It also requires using abi codes, so PyTeal and Teal alone are not good enough. Ultimately, it does not produce an int value.
