How fast?

Afaik it is still the case that if the transaction is not opt in RBF, you get the cash immediately (yes, you read that right!). It was certainly true a few weeks ago, i.e. last I checked.
Most wallets I know (apart from Electrum) opt in though and don't give their user the choice to opt out.
Otherwise I *believe* it waits for only 1 conf, could be wrong on the number.
Ugh the Chivo ATM's are still onchain only? Inexcusable.
And very odd given that it is a win-win for everyone if they move to LN with an onchain fallback.
They have the infra for it already 😵💫
I don't believe Chivo developed their own ATM; they look identical to other ATMs I've seen elsewhere. So likely it's just a matter of of getting someone to actually write the software for LN payments.
I've only seen two ATM brands that supported Lightning. One of which was coins only, and designed for small values.
Which ATM company product is this #[7] ?
At the begging they were Athena, branded with Chivo. Currently I do not know who's the provider. We have made a working LN ATM... Casing still needs to be designed, but everything works fine with our LN ATM.
For those of you who don't know, I do work for the Gov, but also co-founded a Bitcoin only business [High Voltage]. We have created an encryption protocol [Hexsum], a lightweight Lightning Wallet, to bank the unbanked [Blip! Wallet], an encrypted messaging app that uses the LN to send messages [Blip! me App], a working LN ATM, and we also provide software development and cyber-sec services. Investors - partners needed... 😉😉
When I was there in the summer I tested both RBF and non-RBF txs, and found that instant confirmation was inconsistent for both. Often a non-RBF tx required a confirmation, often a RBF tx would give me cash immediately. There were no guarantees either way and the RBF flag didn't seem to make a clear difference.
It's possible that the behavior is tied to your phone number; the ATMs are AML/KYC as getting an El Salvadoran sim card without ID isn't legally possible.
I was able to buy a SIM at pharmacy (haven't come across a mobile carrier yet where I've been) & didn't give my ID when buying
But I haven't been able to activate cause I don't have a tool to open my SIM slot (paper clip failed) - maybe you need to KYC when you activate?
A lot of countries do the ID check when you activate. Or they just skipped a legally necessary step to save time.
I have a Spanish SIM card that should have been activated in my name. I noticed the storekeeper filling it out with someone else's passport details. 😂
I bought a retail SIM card only to learn online activation requires the SV national ID number. Wasted $3.
Instead a kiosk in a supermarket had a guy selling phone plans. I asked for an activated SIM card. He asked for ID. "Oops I forgot it at the hotel." He just went ahead and activated it in his own phone before handing it over. YMMV.
Hmm I might have to do some more testing but my reports were not only from my own experience, but also that of others. But, not scientific because: since I don't actually want to wait, I was recently only using Electrum with RBF switched off (since they have that toggle in their interface), never on.
Also I am using them only occasionally since as mentioned I don't actually trust them (which to my mind is like a 100x bigger issue than LN support! An ATM which randomly decides to not issue cash is not OK!).
Re: SIMs and so on, good point. Behaviour might change if you are using a foreign number.
It's quite possible that they've changed the behavior since I visited too. And also possible the behavior varies from one ATM to another.
