Trust boundary terms
Fraud and wallet security vocabulary explains where users delegate trust, where controls intervene, and where approval flows fail. This hub unifies payments authentication language with crypto wallet risk language.
Fraud, identity, and security
Understand the vocabulary of trust and failure points in payment and wallet security flows.
Identity vs possession
Some terms verify the user, others protect the credential, and others govern signing behavior. Without separating identity, possession, and authorization language, fintech security analysis becomes sloppy.
Operational relevance
This hub is designed for teams that manage fraud rates, wallet UX, recovery flows, and approval risk. The point is not to define security in the abstract, but to connect terms to failure modes that affect real products.
