LNURL in the Real World: Improving Payment Communication for Africa
summary
Explains how LNURL specs are used in production: implements L06 pay request and L16 lightning address endpoints as simple Express routes, calculates a per-currency multiplier in millisats (uses decimals to avoid rounding), and exposes metadata with a currencies array so wallets can request invoices denominated in local fiat. Shows USSD constraints (20s input, 160 chars), live services (mapp.money, a33.mobi, Wallet of Satoshi callbacks), notes description-hash incompatibilities, and pushes the L22 currency draft still awaiting merge.
