Blink primary sources — 2026-04-30

Project status in this pass

  • No canonical standalone whitepaper or litepaper surfaced.
  • The clearest current source of truth is the official site, developer docs, public GraphQL API reference, and open-source app/backend materials.

Primary-source snapshots

1) Main site

  • URL: https://www.blink.sv/
  • Key excerpt:
    • Markets Blink as “The Everyday Bitcoin Wallet.”
    • Public navigation prominently exposes merchant tools, a dollar account, API docs, BTCPay integration, WooCommerce, support, status, and GitHub.
    • This is a strong clue that the product surface extends beyond a consumer wallet into merchant and developer infrastructure.

2) Merchant tools

  • URL: https://www.blink.sv/en/merchant-tools
  • Key excerpt:
    • Says Blink makes bitcoin payments easy for products, donations, and remittances.
    • Describes a point-of-sale web app / “Lightning cash register,” reusable QR-based receiving, and receiving into either Bitcoin or Dollar accounts.

3) API use cases

  • URL: https://www.blink.sv/en/api-use-cases
  • Key excerpt:
    • Describes the Blink API as a hosted GraphQL API on reliable open-source infrastructure from Galoy.
    • Highlights BTCPay plugin support, WooCommerce support, and backend integration for Stablesats dollar-account workflows.
    • Explicitly says teams can later self-host on the Galoy stack.

4) Developer docs intro

  • URL: https://dev.blink.sv/
  • Key excerpt:
    • Describes Blink as a “powerful, cost-effective, and reliable solution” for integrating Bitcoin and Lightning payments.
    • Says flows can be denominated in bitcoin or USD.
    • Highlights Lightning, onchain, and Stablesats pricing plus interactive tutorials.

5) Authentication docs

  • URL: https://dev.blink.sv/api/auth
  • Key excerpt:
    • Says authenticated requests use an X-API-KEY header.
    • Gives a concrete GraphQL example against https://api.blink.sv/graphql.
    • Warns API keys should stay server-side.

6) Self-host overview

  • URL: https://dev.blink.sv/self-host
  • Key excerpt:
    • Says the Blink core banking platform includes what is necessary to launch a “community bank on Bitcoin and Lightning.”
    • Breaks the stack into Blink Core, Stablesats, Bria, Blink CLI, mobile wallet, dashboard, and admin panel.
    • This is the clearest current evidence that Blink should be cataloged as a banking/payments control plane rather than a simple wallet.

7) Public API reference

  • URL: https://dev.blink.sv/public-api-reference.html
  • Key excerpt:
    • Documents a broad GraphQL surface including account wallet lookup, authorization scopes, currency conversion estimation, and business map markers.
    • Confirms Blink exposes a sizeable operational API rather than just a narrow invoice endpoint.

8) Open-source mobile app README

Working conclusion

Blink is best cataloged as Bitcoin banking and payments control-plane infrastructure that happens to include a consumer wallet, rather than as a standalone retail wallet brand.
