A Novel Machine Learning-Based Analysis Model for Smart Contract Vulnerability

Algorithm 1

Get all node and node’s value from AST.

	Input: : AST of the smart contract; : an empty list; : the keys of AST;
	Output: : all node of AST in the form of list
	if is list type then
	fordo
	end for
	else
	if is dict type then
	fordo
	end for
	else
	end if
	end if
