Crypto payments for merchants are still too complicated.

ScanSettle fixes that.

→ Merchant shows QR code
→ Customer scans & pays in any token
→ Instant settlement on @solana via @KiraPayOfficial

Simple as it should've always been ⚡

Requesting your kind attention to this matter. If GST is being collected, why does the bill display "GST Number: undefined"? Who is responsible and accountable for such discrepancies?
Please take action!!!

Hotel Astor Shri Balaji Dosa Restaurant, Fraser Road, Patna-1 charged CGST ₹22.22 + SGST ₹22.22, but the bill shows "GST Number: undefined". Requesting @askGST_GoI @cbic_india @Commercial_Tax to clarify whether this billing format complies with GST rules. #GST #Patna

Another milestone in my DSA journey. 🚀

I've started noticing a real change in the way I approach problems—my critical thinking has improved so much compared to where I started.

Just wrapped up the Koko Eating Bananas problem. On to the next challenge! 💪

#DSA #LeetCode

[Rahul Kumar @syscallr]

🚀 Milestone unlocked!

Solved my first 50 LeetCode problems. 💻

Every problem taught me something new—binary search, sliding window, stacks, linked lists, hashing, and debugging my own mistakes.

Still a long way to go, but consistency beats motivation.

🎯 Next target: 100 LP.
