Guides on this site
Test smart contracts through state invariants
Define the properties funds and privileges must preserve, then exercise callbacks, transaction sequences and exceptional conditions locally.
Prevent business-logic flaws with server-side invariants
Recompute prices on the server, run workflows as state machines, build reset links from configuration, limit valuable flows, and turn each business rule into an invariant that the database and the tests both check.
Abuse case library: tests and controls by feature
Recurring abuse cases for sign-up and login, password reset, MFA enrolment, invites, file upload, payments and coupons, webhooks, search, export, admin and AI chat or agents: the attacker goal, preconditions, a concrete test and the control, each linked to CWE and CAPEC.
