Strike
A Bitcoin/Lightning payments app and API with fiat on/off-ramp — the regulated-custodian bridge between agent payments and bank rails.
What it is
Strike is a Bitcoin/Lightning payments app and developer API for sending and receiving, converting USD ↔ BTC, and making Lightning-native programmatic payments. Its REST/JSON API (with OAuth for third-party integrations) makes it a practical on/off-ramp at the edge of the substrate: where agent activity needs to touch fiat or bank rails, a regulated custodian like Strike is the bridge.
This is a Border Zone tool, not pure substrate — it interfaces the Bitcoin economy with the incumbent financial system. See The Border Zone for the bridge architecture and the compliance-at-the-gateway pattern.
When to use it
- Fiat on-ramp / off-ramp at the boundary between agent treasuries and bank rails.
- Lightning-native send/receive where you want a managed, compliant counterparty.
- Programmatic payouts/collections via a documented REST API.
Quick start
Build against the API documented at docs.strike.me (developer portal at strike.me/developer/), using OAuth for third-party access. Availability is gated by jurisdiction.
Gotchas
- Regulated custodian — Strike holds customer funds and operates under money-transmission / BitLicense regulation. Custodial counterparty risk and KYC apply; this is a deliberate trade at the bridge, not substrate-level sovereignty.
- Geo-restricted — availability depends on jurisdiction and regulatory coverage.
- Closed-source — the stack is not self-verifiable; you trust the operator.
