Retail giant SPAR dropped a bombshell today. They've wired Bitcoin Lightning payments directly into their app across Switzerland. We're talking about a chain that operates 13,900 locations spanning 48 countries.

This isn't some pilot program at three stores. Lightning Network—the layer that makes Bitcoin transactions instant and dirt cheap—is now live for everyday grocery runs. Imagine grabbing your milk and bread, then settling the bill in sats faster than your card reader boots up.

The Switzerland rollout could be the wedge. SPAR's footprint stretches across Europe, Asia, and Africa. If the Swiss trial proves seamless, other markets might follow. Traditional retail embracing crypto rails at this scale? That's the kind of momentum people have been waiting for.

Payment infrastructure is shifting. Slowly, then suddenly.
