• Tags: bitcoin-ecosystem
• Summary: CoinCorner is a Bitcoin operator stack that happens to include retail exchange. The useful parts are the business API, recurring Lightning payouts, Send Globally routing, and Bolt Card infrastructure, not the brokerage veneer.
• What it does:
  • Provides a retail Bitcoin account for buying, selling, storing, sending, and receiving BTC
  • Exposes an authenticated Bitcoin and Lightning API so businesses can add Bitcoin/Lightning support without running their own wallet stack
  • Lets users send and receive over Lightning using invoices, Lightning addresses, and LNURL flows
  • Supports recurring Lightning payments on daily, weekly, monthly, or yearly schedules
  • Offers the Bolt Card, an NFC card that pays Lightning invoices from a CoinCorner balance and can also be loaded as a sats gift card
  • Runs Send Globally, which routes transfers from GBP/EUR or BTC balances across Lightning and settles to recipients in local fiat bank accounts or mobile-money wallets through partner rails
• Key claims:
  • The CoinCorner API homepage says businesses can support Bitcoin and Lightning “without needing any wallet infrastructure,” which is strong evidence that CoinCorner is selling reusable payments infrastructure rather than only an end-user app
  • The API docs document HMAC-SHA256 request signing with API key, signature, and nonce requirements, plus rate limits, which reinforces that the API is meant for production integration
  • The Lightning support docs say users can send via Lightning invoices, Lightning addresses, or LNURL, and receive through LNURL or generated Lightning invoices, with Lightning withdrawals described as free from CoinCorner’s side
  • The recurring-payments article says customers can schedule Lightning payments daily, weekly, monthly, or yearly to a Lightning Address or LNURL pay endpoint, which makes CoinCorner look like a programmable payout rail rather than only a send button
  • The Send Globally docs say GBP/EUR or BTC balances are converted into BTC, moved across the Bitcoin Lightning Network, and then converted into local currency for payout to the recipient’s bank account or mobile-money wallet in supported countries
  • The Bolt Card docs say the card uses NFC, Lightning, and LNURL, can pull directly from a CoinCorner BTC balance at point of sale, and can also be preloaded as a gift card that another Lightning wallet can sweep
  • The main site navigation and search snippets prominently surface Business Accounts, Send Globally, and The Bolt Card alongside normal buy/sell/store flows, which fits a broader payments-and-remittance platform framing
• Whitepaper: No canonical standalone CoinCorner whitepaper or litepaper surfaced in this pass. The clearest current sources of truth were CoinCorner’s API docs plus first-party support articles for Lightning, recurring payments, Send Globally, and the Bolt Card; see ../whitepapers/coincorner-primary-sources-2026-05-02.md.

Internal linkages

• Best upward reads: strike and btcpay-server.

Control surface

• Practical authority sits in API-key issuance, custody and account policy, recurring-payout scheduling, remittance-partner routing, and the wallet/card interfaces CoinCorner chooses to expose.

• Read it as a Bitcoin payments operator with exchange features attached, not as a category-defining exchange or wallet note.
