Strike is a financial technology company founded by Jack Mallers that uses the Bitcoin Lightning Network as a settlement rail to deliver instant, low-cost global payments and remittances denominated in fiat currencies. It abstracts the technical complexity of Bitcoin and Lightning from end users, converting value at the edges so that senders and recipients may transact in their preferred local currencies without needing to hold cryptocurrency. Strike competes with legacy remittance operators and correspondent banking channels by exploiting Lightning’s near-zero fee structure and sub-second finality to offer dramatically lower-cost international money movement.
Overview
- Strike was founded in 2019 by Jack Mallers and is headquartered in Chicago, Illinois. It provides consumer-facing mobile applications and a developer-facing API under the Open Payments Protocol standard, enabling businesses and individuals to send and receive money internationally.
- The platform’s core innovation is the use of Bitcoin and the Lightning Network as a neutral, permissionless monetary rail, invisible to end users who interact only with their local currency. This allows Strike to route a US-dollar payment to El Salvador in seconds at a fraction of the cost of a traditional Remittance transfer via services such as Western Union or SWIFT Network.
- Strike played a prominent role in El Salvador’s adoption of Bitcoin as legal tender in 2021, providing the technology behind the Chivo wallet and advising the Salvadoran government on Bitcoin adoption policy.
- The company holds money-transmitter licences in multiple US states and operates under AML Compliance regimes, distinguishing it from purely self-custodial Lightning Network wallets. This regulatory posture enables institutional and business integrations but introduces custodial risk for end-user funds.
- Strike’s developer API supports programmatic Instant Settlement into bank accounts, enabling e-commerce and payroll applications to leverage Lightning Network without building their own Node Operation infrastructure.
Key Mechanisms
- Edge Conversion Model — the sender pays in their local Fiat Currency; Strike converts to Bitcoin satoshis internally, routes via the Lightning Network, and the recipient’s Strike account or connected bank account receives the destination currency. Neither party need manage Cryptocurrency.
- Lightning Network Settlement — value flows through pre-funded Payment Channel networks, exploiting Hash Time-Locked Contracts (HTLCs) to enforce atomic multi-hop routing. This is the mechanism that provides Instant Settlement and near-zero fees.
- BOLT Protocol Compliance — Strike’s infrastructure adheres to Basis of Lightning Technology (BOLT Protocol) specifications, ensuring interoperability with third-party Lightning Network nodes, wallets, and services.
- Liquidity Management — Strike maintains inbound and outbound Lightning Network liquidity across payment corridors to ensure routing success rates. This is a capital-intensive operational requirement that functions as a moat against smaller competitors.
- Invoicing and LNURL — Strike supports Lightning invoices (BOLT-11) and LNURL-pay extensions, enabling interoperability with wallets such as Phoenix, Breez, and Muun, as well as point-of-sale integrations.
- Fiat On-Ramp / Off-Ramp — domestic bank-account linkage (ACH in the US) and card funding provide the fiat interface, with regulatory compliance enforced at these entry and exit points.
- API Integration for Merchants — Strike’s merchant API enables e-commerce platforms to accept payments in any currency and settle in their preferred currency, abstracting Cryptocurrency volatility.
Applications and Use Cases
- International Remittance — workers in the United States send money to family members in El Salvador, the Philippines, Nigeria, and elsewhere at dramatically lower fees than traditional Remittance operators. The Lightning Network corridor removes Correspondent Banking intermediary fees and multi-day settlement delays.
- Merchant Payments — physical and online merchants in supported markets accept Strike payments, settling to bank accounts in local currency, without needing to hold Bitcoin or manage Cryptocurrency Exchange exposure.
- Micropayments — Strike’s Lightning integration supports value transfers below one US cent, enabling use cases such as pay-per-article media, streaming-money for API consumption, and machine-to-machine payments that are impractical on traditional payment rails.
- Payroll — employers use Strike’s API to pay international contractors and employees in their local currency, funding payroll in USD and routing via Lightning Network to recipients who receive local currency equivalents in seconds.
- Bitcoin Savings — Strike offers a “buy Bitcoin” feature that allows users to accumulate Bitcoin as a savings instrument, separate from the payments function, addressing the store-of-value narrative distinct from the medium-of-exchange narrative.
- Humanitarian and Financial Inclusion Payments — in regions with limited banking infrastructure, Strike accounts can be opened with a mobile phone and an email address, lowering the barrier to Financial Inclusion for unbanked populations.
- Point-of-Sale Integration — retail merchants integrate Strike via QR-code-based Lightning invoice flows, enabling tap-to-pay and scan-to-pay at low marginal cost.
Competitive and Strategic Context
- Strike occupies a position distinct from self-custodial Lightning Network wallets (e.g. Phoenix, Breez) in that it holds user funds in a regulated custodial account, enabling compliance-grade integrations but sacrificing the self-sovereignty that Bitcoin proponents prioritise.
- Versus Decentralised Finance platforms, Strike is deliberately centralised at the application layer, accepting regulatory friction in exchange for accessibility and fiat interoperability.
- Versus Open Banking rails such as SEPA Instant or FedNow, Strike’s advantage is global reach in corridors where domestic faster-payment rails are absent or unconnected, and in cross-currency flows where Correspondent Banking fees remain high.
- The Financial Inclusion dimension is significant: Strike accounts are accessible to individuals without a traditional bank account, provided they have a mobile device, offering a pathway into the global payments system for underbanked populations.
- Competition includes other Lightning-native payment processors (BitPay, OpenNode), as well as FinTech remittance platforms (Wise, Remitly), though Strike’s direct Lightning routing and edge-conversion architecture differentiates it on cost in specific corridors.
Standards and Regulatory Context
- BOLT Protocol — Strike’s Lightning implementation follows the Basis of Lightning Technology specifications (BOLTs 1–12) maintained by the Lightning Network developer community, ensuring wire-level interoperability.
- Money Transmitter Licences — Strike holds licences in the majority of US states and operates under FinCEN (Financial Crimes Enforcement Network) regulations as a money services business, requiring AML Compliance for all account holders.
- Open Payments Protocol — Strike is a contributor to and adopter of the Open Payments Protocol standard, enabling interoperable payment initiation across different wallet and bank implementations via open web standards (Interledger Protocol lineage).
- El Salvador Bitcoin Law (2021) — Strike’s involvement in El Salvador’s legal-tender Bitcoin framework constitutes a real-world regulatory pilot for Lightning-native national payments infrastructure.
- BIP-21 URI Scheme — Strike supports the Bitcoin Improvement Proposal 21 URI scheme for payment request encoding, enabling interoperability with Bitcoin wallet software.
- LNURL Standards — Strike implements LNURL-pay and LNURL-withdraw, community-driven Lightning interoperability extensions that simplify payment flows across wallet implementations.
