Abstract
Blockchain as a technology is now integrated into a wide range of technologies from online market places to supply chain management. A crypto wallet enables its owner to interact with these technologies via currency tokens (fungible tokens). To be of any practical use, the wallet should have the feature to split fungible tokens into smaller denominations. This can be achieved via a factorization algorithm. If these tokens, by design, are made physically available at the end user side; there is a risk of the wallet value being changed by either improper factorization or by exploiting system vulnerabilities. This paper proposes a factorization system where merkle root value of individual tokens is used as root of trust element to validate wallet value integrity.
