I mean, for Bitcoin, that couldn’t really work, unless you get the fees back via lightning, as you can’t simply change the transaction without the sender doing that. But I guess you could boost your transaction by watching an add, like you can boost it with mempool.space. nostr:npub18d4r6wanxkyrdfjdrjqzj2ukua5cas669ew2g5w7lf4a8te7awzqey6lt3
To boost a transaction might set you back a bit, but if you don’t mind watching some ads, have the advertiser pay for the boost.
