 Someone gave me 1000 sats in ecash from a random mint I don't trust and I wanna see if it's backed by real bitcoin. 

First 10 replies get 100 says each! 
 Shoot it let's test them 
 Oh just giving sats? I'd thought you'd share the mint. 

All good thx for the sats thought we were testing if the mint was backed 
 heeeyy 
 What's the mint? 
 How do i get this. Do i need to post some sort of ecash wallet receive address? I can dive in and download a mobile wallet if one exists 
 Guess you have me blocked or cant see my messages based on relays maybe 
 How do even receive it offline? Makes no Sense 
 Speeeaaak! 
 Someone can send fake sats with ecash? How do you see if it’s backed? 
 By zapping it all 
 Spend it over lightning. If it got sent, it was backed. Of course it doesn't prove anything about the remaining sats. 
 So if I don’t spend it, there is no way to know it’s fake? 
 that sounds like a trap 
 I didn’t know this was possible and now my trust in ecash is broken. 😞 
 never tried it 
 Good. Ecash is a custodial system. It is exactly like having a Wallet of Satoshi, but with a massive difference... they don't hold accounts for their users, they only track issued ecash notes and spent ecash notes.

This means that every time you spend, they have no idea who is spending, just that they received some ecash and need to perform a service.

It's a step in the right direction, but mints need to prove themselves like a company like Wallet of Satoshi has done by building a reputation for themselves as reliable. 
 That makes sense. But why do I feel like scamming potential gets to the individual level with ecash instead of companies. Meaning I can be a mint and give you fake ecash and as long as you don’t have internet to verify it. I’m good to even double spend it and pay a couple people before they get the chance to verify, no? Or am I blowing things out of proportion. 
 Can you elaborate or explain the concern more succinctly?

If you are simply referring to someone (not the mint) being able to double spend ecash tokens while there is some internet outage, then yes this is possible. However this does not inflate the supply, because when the internet is restored, the token needs to be refreshed and it is first connected, first serve. The rest will stop trusting this customer.

Of course you can choose only to receive offline ecash from people you trust, and keep in mind that no other custodial solution is able to offer offline payments, but if they did, they would have similar issues. 
 Yes exactly that. But thanks for clarifying. 
 Correct.  
 Send the fake ecash!  
 Wut 
 Here :) 
 🌽🌽🌽🌽🌽 
 It’s fake 
 Am I too late? 🤔 
 *out of breath* .... Did I make it?? 
 *running to the sats * 
 Awww, 14th 
 What was the outcome? Backed by real bitcoin? 
 Not sure 
 I'm your huckleberry. 
 Easy. Just do a multimint swap to a mint that you do trust. 

Doesn’t anyone actually use ecash? 
 Is this 3d chess you are playing ? 
 Says? I want says! 
 ewhat? 
 Can your wallet have both cashu and fedimints mints and inter operate
