See what the chain
doesn’t explain.
Research, tools and field notes that turn execution traces, state changes and infrastructure noise into something engineers can actually use.

SIGNAL LABFrom a failed transaction
From a failed transaction
to a useful explanation.
MEDGA follows evidence across execution, storage, calldata and infrastructure instead of treating each layer as a separate problem.
Our research method →Execution graph / sample trace12 calls · 4 storage writes · 2 external boundaries
Trace the call path
Follow value and control flow before reading symptoms.
Map state changes
See exactly what changed and where the cost accumulated.
Keep infra in frame
RPC behavior and operational context stay part of the explanation.
