Colombia passed 100 Bitcoin-accepting merchants this week, with Medellin and Bogota leading the count. An AI agent bought electrolytes from a live Shopify store over Lightning in 30 seconds. And BTC Map logged 1,000 new merchants in March alone. Bitcoin payments are scaling through the rails merchants already use — from QR networks to e-commerce platforms to informal tipping at a South African mall.
Colombia passes 100 merchants: Colombia now has more than 100 merchants accepting Bitcoin, with Medellin and Bogota leading the expansion. Lightning is powering fast payments in hospitality, and local firms offer instant conversion to Colombian pesos to reduce friction for merchants. Field work by @ColombiaP2P and @satoshiteam_ helped build the BTCMap coverage that makes these merchants discoverable.
Spotlight: An AI Agent Bought Electrolytes Over Lightning
Lightning Enable completed a live agent-to-merchant purchase this week. Claude — an AI agent — discovered Salt of the Earth's Shopify store, browsed the catalog, selected a product, paid an invoice for 38,561 sats (~$27.67), and placed the order in roughly 30 seconds. No checkout page, no account, no card. The order was fulfilled on a live Shopify merchant, not a demo. Lightning Enable (@lightningenable) describes the stack as deployable for any Shopify merchant through L402 payment flows — payment acts as authorization, and Lightning provides push payments with instant settlement.
The same week, Lightning Labs (@lightning) released the L402 SDK with TypeScript and Python bindings, support for Vercel AI SDK and LangChain, per-request and per-domain budget controls, and WASM support for browsers and edge environments. The live merchant purchase and the developer tooling arrived in the same seven-day window — machines are starting to use the same rails humans use.
1) Merchant & Enterprise Adoption
Merchant reach expanded through existing payment networks and on-the-ground verification this week.
- South Africa — 700,000 Scan to Pay merchants and Plett hits 120 shops: BitcoinFriendlySA (@NickDarlington) published a guide describing how to pay with Bitcoin at 700,000 Scan to Pay merchants across South Africa — reach through an existing QR acceptance network, not a separate Bitcoin-only checkout flow. Meanwhile, MoneyBadger (@MoneyBadgerPay) reported that Plett's Bitcoin merchant count reached 120 shops, up from an earlier prediction of 30. Dense local clusters and national QR rails are converging.
- El Salvador — Bitcoin Coast verifies 51 merchants in 3 days: Bitcoin Coast (@BitcoinCoast_sv) said it made 51 map updates in three days by knocking on doors, verifying Bitcoin acceptance, distributing free materials, and updating its interactive map. Reliable merchant verification matters as local Bitcoin economies grow — field checks reduce stale listings and improve discoverability.
2) Payment Infrastructure
Infrastructure progress centered on interoperability with existing checkout rails and cross-border payout operations.
- India — Fedi links Bitcoin to UPI QR payments: Fedi (@fedibtc) said its 256D Mini App lets users scan India's UPI QR codes, pay from a Fedi wallet in bitcoin, and have merchants receive rupees. The UPI network connects more than 500 million consumers and 65 million merchants — Bitcoin spendability through the checkout behavior India already uses.
- Global — BTC Map adds 1,000 merchants and 10 communities in March: BTC Map (@btcmap) reported 1,000 new merchants and 10 new communities added in March, alongside Android localization, a new web map drawer UX, and a major API expansion. The merchant additions are the clearest public expansion metric for Bitcoin spending discovery this week.
- Africa — Mavapay processes millions monthly over Lightning: Mavapay (@mavapay) described using Lightning for instant cross-border transactions and business payouts, processing millions of dollars in payments monthly as it expands from Africa. It highlighted near-instant settlement, low transaction costs, and privacy through off-chain channels. This is one of the clearest production-use volume signals in the current set.
3) Circular Economy & Ground-Level Proofs
The deepest spending evidence this week came from South Africa's tourism infrastructure, informal tipping, and cross-border disbursements in East Africa.
- South Africa — a 10-day Bitcoin-paid trip across six circular economies: Bitcoin Ekasi (@BitcoinEkasi) promoted a trip organized by UnravelSurf where the private bus, guide, surf coach, and beachfront hotels are all paid in Bitcoin. The itinerary spans BitcoinWitsand, BitcoinKaroo, BitcoinLoxion, BitcoinPlett, BTCSedgefield, and Bitcoin Ekasi — a multi-service tourism bundle built around Bitcoin payments, not a single-merchant showcase.
- South Africa — car guards accept Bitcoin tips at Langeberg Mall: Car guards at Langeberg Mall can now receive tips through MoneyBadger and Blink by having payers scan Zapper QR codes — no smartphone needed on the recipient side. This extends Bitcoin payments to informal, low-ticket service work that conventional digital payment tools usually cannot reach.
- Kenya and Burundi — Bitcoin Babies delivers sats stipends across three countries: Bitcoin Babies (@BtcBabies) said its first quarterly batch payment delivered stipends in sats to mothers and team members across Kenya and Burundi, powered by Blink. One transaction, three countries — extending Bitcoin's payment role beyond retail checkout into recurring operational disbursements.
From 100 Colombian merchants to an AI agent buying electrolytes in 30 seconds — same protocol, every interface. See you next week.
