Bitcoin wallets used at Lake Atitlán

Why Bitcoin Beach Wallet became the starting point

When Bitcoin Lago began onboarding merchants in 2022, the team compared several Lightning wallets, including Moon, BlueWallet and Wallet of Satoshi. Patrick Melder said they chose the Bitcoin Beach wallet, built by Galoy, because it had a merchant map. Early on, there were no accepting shops in Panajachel to show, so the team could point to El Zonte in El Salvador as an example. The map made an unfamiliar idea visible: a merchant could see that other small businesses already accepted bitcoin.

The other practical feature was payment by username. Patrick described a visitor paying a pizza shop from a hotel, without needing the shop’s full payment details. The project also used the name BitcoinLake in the wallet. Patrick said Galoy did not sponsor Bitcoin Lago, but its team helped with backend questions and wallet issues. In the early stage, that support mattered alongside the app features.

There was a local-currency gap. At first, the wallet displayed US dollars and bitcoin, not Guatemalan quetzales. Patrick called this a small issue because merchants could do the conversion in their heads. A separate point-of-sale tool helped show prices in local currency: Patrick said a volunteer built a web-based POS that worked in any currency, and the team made QR codes so employees could accept Lightning payments. This addressed the checkout experience, not the wallet’s custody model.

Custody, and the search for a better fit

The Bitcoin Beach wallet was custodial. In plain terms, a custodial wallet means another service holds the keys that control the bitcoin. With self-custody, you hold those keys yourself. Patrick explicitly flagged custody as a drawback in a 2022 interview published in February 2023. In another interview, he said the team had no good self-custody option for everyday merchant use at the time: hardware devices seemed costly for the small balances involved, while children-built SeedSigner kits were useful for education but not a practical community-wide system.

Fedimint was explored as a possible community-based alternative. Patrick said Bitcoin Lago had been selected as a pilot community through an application, but also described the system as beta with limited functions. The evidence supports a pilot connection and interest, not a claim that local merchants broadly used a Fedi federation. Later, Eliazar mentioned using Blink, Fedi and sometimes Wallet of Satoshi. These are accounts of tools in use or being explored at different moments, not a single permanent wallet policy.

Blink at the lake, and what a visitor needs

Bitcoin Beach Wallet later became Blink. At Lago Summit 2023, Blink visited and showed merchants’ Lightning payment cards with instructions to pay to a Lightning address or scan a QR code. A visitor video from the same period follows people paying for food and other stops around Panajachel with Lightning. The video description says visitors can use Blink or their preferred Lightning-enabled bitcoin wallet.

That compatibility is practical: a visitor does not need the same app as a merchant, as long as both wallets can send and receive Lightning payments. In a May 2023 video, a visitor used Wallet of Satoshi to pay a breakfast bill to a merchant’s Bitcoin Beach wallet account, including a tip prompt. Eliazar’s own account also traces his first bitcoin experience to downloading Wallet of Satoshi after Patrick showed him a transaction. These examples document use, not an endorsement of any wallet.

For merchants who want to hold bitcoin, Eliazar said some had moved funds to cold wallets, and Ordermoon’s interview described teaching custody step by step as balances grow. In February 2024, Eliazar thanked Swiss donors and named BitBox among tools intended to support bitcoin education for local children and adults. This is evidence of educational equipment and a gradual learning path, not proof every merchant has moved away from a custodial wallet.

For a visitor, the useful takeaway is simple: ask the merchant which Lightning QR or address to use, then pay from a Lightning wallet you already use. The sources show a real Wallet of Satoshi-to-Bitcoin Beach payment, and later public branding as Blink. They do not establish that every shop accepts every wallet or that each map listing is still active. Ask before ordering, and treat the wallet choice as a payment method, not financial advice.
