As semiconductor node sizes shrink, transient hardware faults pose a growing risk to computing systems, especially in environments where reliability is critical.
\Gls{wasm}, a binary-code format developed for the web, is increasingly used in embedded systems through standalone runtimes such as the \Gls{wamr}.
This thesis investigates \Gls{wamr}'s compatibility with hardening techniques for transient hardware faults through systematic single-bit fault injection on a simulated IA-32 CPU using the \Gls{fail} fault-injection framework.

The interpreter and \Gls{aot} execution modes of \Gls{wamr} are compared under fault conditions and software-based hardening techniques are evaluated at two levels: (I) the language/application level, by hardening source programs before compilation to Wasm, and (II) the runtime level, by hardening \Gls{wamr} itself.
