Payment addresses are hostile to humans. Every serious attempt to fix that has arrived at the same answer: a readable handle mapping to the underlying account. Hashtag Wallet names that idea in two pieces of vocabulary everyone already has. The hashtag half signals social and public; the wallet half signals money. Together they describe a category that keeps being attempted because the underlying need is genuine and unsolved. It suits a consumer payments app, a naming or identity service, a creator monetisation product, or a social layer over an existing wallet.
