Yeah that was me! I made scratch off tickets at the nostr:nprofile1qqs0m7vn2q3zrccumrqkxaepzmdpkx20dgu6m4vyx5crd9v5w8htdtcpzdmhxue69uhhqatjwpkx2urpvuhx2ue04zvmyp halving party. It was only semi successful. I was using an lnbits beta instance and people had a hard time redeeming. But they were giveaways anyways so 🤷 . Cashu seems a better choice for this sorta thing. I didnt know enough abt it (or it wasnt quite ready yet?) back then.
