# Summary of Capabilities Helios lets Bitcoin holders put idle BTC to work or unlock liquidity—without ever leaving the Bitcoin security model. * **Earn or borrow:** Deposit BTC or BTC-native assets to accrue yield, or post assets as over-collateralized security to borrow additional BTC, stablecoins, or other assets. * **Flash loans:** Instantly borrow any reserve asset with **zero upfront collateral**—provided the loan (plus a small premium) is repaid within the same transaction. Use cases include arbitrage, self-liquidation, and one-click refinancing. The premium flows straight back to depositors as extra yield, while unreturned loans simply revert the entire TX, keeping pool funds safe. * **Tax-efficient liquidity for miners:** Mining treasuries can pledge freshly minted BTC to obtain stablecoins instead of selling or wrapping, sidestepping taxable disposal events while retaining upside exposure. * **BTC-denominated accounting:** All loans, interest accruals, and risk metrics are expressed in satoshis, keeping incentives fully aligned with long-term Bitcoin accumulation. * **Single-transaction UX:** A single Bitcoin transaction handles deposit, withdrawal, repay—or a flash-loan cycle—no multi-step bridging or wrapping. * **Partial collateral swaps:** Borrowers can dynamically rebalance collateral versus debt without closing positions. * **Adaptive interest & risk controls:** Rates, LTVs, and liquidation thresholds auto-adjust block-by-block to mempool congestion and price volatility. * **Optional compliance modules:** Role-based permissions, BIP-322 attestations, and KYC/KYB hooks integrate seamlessly with custodians, fund administrators, and auditors. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
