The line is secured by BTC reserves and pledged hashrate. The collateral is posted once and supports the facility across repeated draws and repayments, so liquidity is available on demand without re-underwriting.

​
Reserves and pledged hashrate

Two things back the line: BTC reserves you post, and the hashrate of your fleet, pledged with block rewards routed to a monitored program address. Together they give the facility a controlled, verifiable production stream alongside the posted BTC, rather than an unsecured claim on your output.

​
Undrawn reserves keep earning

Undrawn BTC does not sit idle. Reserves backing the line earn 2% APY while they secure the facility, so posting collateral does not mean parking capital. Your principal stays long BTC and continues to compound while only the drawn balance carries a cost.

​
No margin calls

The facility does not issue margin calls or force liquidations on a BTC price move. Repayment comes from mining production against a fixed collateral base, so a decline in BTC does not trigger a demand for more collateral at the worst possible moment. This is the structural difference from a BTC-overcollateralized loan, which demands more Bitcoin precisely when your balance sheet is most stressed.

​
Custody

Collateral is held with qualified custodians or in audited on-chain contracts. The custody arrangement is confirmed during onboarding and keeps pledged assets controlled and verifiable throughout the life of the line.
