RedStone has introduced live loan-to-value (LTV) data feeds for Spark's Bitcoin collateral held at Anchorage Digital, enabling continuous onchain monitoring of offchain BTC collateral. This integration allows institutional lenders to keep their Bitcoin in regulated custody while accessing DeFi lending markets, addressing a major trust gap between traditional finance and decentralized finance. The setup, launched in January 2026, currently supports $150 million USDC loans against $222 million BTC collateral, with RedStone's feeds ensuring synchronized, real-time collateral health data to trigger margin calls and liquidations as needed. This development strengthens Spark's role as an institutional-grade interface within the Sky ecosystem, with Anchorage as the custodian and RedStone as the oracle provider, though it also introduces risks if the oracle data fails during market volatility.
