Abstract	Crowdfunding is the most favored approach by which money is raised for a startup, socialcauses, or creative initiative through the contribution of a large number of small amounts. However, thosetraditional crowdfunding platforms face certain issues relating to fraud, high fees, transparency, and investors' control. All those problems can be solved much better by using blockchain technology since itenables the secure, transparent and automatic handling of funds without middlemen. This paper tries tolook at the various ways by which blockchain technology betters crowdfunding facilitation through smartcontract arrangements. Recent studies are construed to show how features such as immutable recordkeeping and automatic execution add trust and security. Challenges presently include system scalability, thelegal framework, and smart contract risk. It carries out fraud detection using a better Feature TokenizerTransformer model, getting 95% right, with 92% precision, 88% recall, and an F1-score of 86.5%.
