Yup. I looked into Blink, and I guess its USP is that StableSats function (pretty cool, not gonna lie), though considering the advancements in Lightning, we'll be getting lightning stablecoins soon so most likely a lot of other apps, include LifPay, would potentially having a similar competing element of having stables in the wallet.
One thing I noticed tho when I attempted to test out Blink, their registration requires a phone number, so that's a bummer. Hopefully they'd also add Nostr login, or even just email registration at least.
Speaking of ecash, considering LifPay already has nostr login, its not that far off actually, as in nostr there's already integrations of ecash and people are using it to send each other to their addresses directly (basically, its almost a matter of just visually presenting the amount you already might have of ecash tokens that's residing within your nostr address, to showcase and use it in LifPay).
