Swan Bitcoin

What it is. A US Bitcoin-only company built around recurring accumulation (dollar-cost averaging) and long-term holding, with automatic withdrawal to self-custody. No altcoins.

What it bridges. Fiat (US bank) ↔ BTC, optimized for scheduled recurring buys rather than ad-hoc trading.

Agent access. Primarily a scheduled-buy model rather than a general programmatic trading API — best fit for an agent that wants a hands-off, rules-based path to build a Bitcoin reserve over time.

How an agent uses it. KYC once; configure recurring buys funded from a US bank; auto-withdraw to a self-custody address on a cadence. This is a reserve-building tool, not an operational off-ramp.

Coverage. United States–focused.

Dependencies & payment. A KYC’d US Swan account. Payment is recurring buys funded from a US bank with automatic withdrawal to self-custody — a reserve-building cadence, not an API trading or operational off-ramp surface.

Gotchas. Custodial at the buy boundary (mitigated by auto-withdrawal to self-custody); oriented to accumulation, so it does not serve fast operational conversion or Lightning off-ramp needs the way Strike does.
