Onchain Survival Playbook
This track is built for users who are tired of feeling one click behind the product. It teaches how to read authority, route stages, hidden counterparties, delay states, and recovery signals before routine screens become expensive mistakes.
These are the habits the track should leave behind. If they are not changing how you read prompts, routes, and confirmation screens, the track is not doing its job yet.
What actually happened
These are public cases and repeated real-world patterns turned into teachable stories. Use them to see how small shortcuts become expensive outcomes in real product flows.
A normal-looking stablecoin swap became a $215K lesson in route pressure
A widely reported March 2025 sandwich attack case showed how an apparently ordinary stablecoin swap could still be vulnerable once timing and ordering pressure entered the route. More than $215,000 was reportedly lost even though the surface flow looked routine.
One real-world failure usually teaches faster than ten abstract warnings.
If the pair is boring and the interface looks normal, the route probably does not need a deeper stress test.
The route looked ordinary enough to pass as safe by default, which is exactly why the user could underweight execution pressure and route fragility.
These are the exact product moments where this kind of mistake usually first looks harmless.
One of the most dangerous route states is 'nothing here looks dramatic enough to deserve caution.'
Use ordinary-looking routes as a reason to test assumptions, not as a reason to skip them. Calm flow can still carry fragile execution.
Approval phishing keeps working because routine beats attention
Chainalysis reported in July 2024 that approval-phishing losses had exceeded $2.7 billion since May 2021. The pattern succeeds because the user experiences the signature or approval as routine friction instead of as lasting authority.
One real-world failure usually teaches faster than ten abstract warnings.
If this looks like one more normal wallet step, it is probably harmless to clear quickly.
The prompt does not need to feel dramatic to be expensive. It only needs to feel common enough for the user to skip translation into plain language.
These are the exact product moments where this kind of mistake usually first looks harmless.
The route that feels easiest to normalize is often the one most worth slowing down for.
When the prompt feels routine, inspect harder. Routine is not a safety property; it is often the camouflage.
Before you sign or confirm
This section should help in the moment of risk. Keep one question in mind: what should I check right now before giving authority or sending the route forward?
Before you continue under pressure
Decision flow
Do not use this like a reading section. Use it as the order of operations when the screen is asking for authority or final confirmation.
How to think through it
Read the screen without trusting the mood of the screen
Start with the hard details the route cannot hide: stage, chain, contract, recipient, and authority scope.
Reduce exposure before you chase certainty
If the route is not fully legible yet, smaller size and slower pace are often the highest-value tools available.
Recover from proof, not from adrenaline
When state gets unclear, gather the route facts first. Retry, support, and cleanup should follow diagnosis rather than replace it.
Signals to notice
That small friction often points to the real unresolved risk.
That is usually a sign that diagnosis is still missing.
Smooth presentation can hide new counterparties, permissions, or route stages.
