RedStone has started providing live loan-to-value (LTV) data feeds for Bitcoin collateral used in the Spark protocol on Anchorage Digital, a federally regulated crypto custodian. The move bridges decentralized finance with traditional finance infrastructure, combining DeFi lending with a custody platform that banks and institutions already trust.
How the integration works
Spark is a DeFi lending platform built on the MakerDAO system. Borrowers deposit Bitcoin as collateral to take out loans in stablecoins. To manage risk, the protocol needs real-time LTV ratios — the value of the loan compared to the collateral. RedStone now supplies those live feeds directly to Anchorage, the custodian that holds the Bitcoin. That means Anchorage can monitor collateral health without relying on delayed or off-chain data.
The integration is technical but the effect is straightforward: institutional clients using Anchorage to custody their Bitcoin can now borrow against it on Spark with up-to-the-minute LTV visibility. Anchorage is a qualified custodian regulated by the Office of the Comptroller of the Currency, so the data feed meets compliance requirements for large investors.
One of the biggest barriers to institutional DeFi adoption has been the gap between crypto’s wild east and traditional finance’s rulebook. Regulated custodians like Anchorage offer insurance, audits, and regulatory oversight — but they’ve struggled to connect to DeFi protocols that rely on real-time, on-chain data. RedStone’s live LTV feeds close that gap.
With live data, Anchorage can trigger alerts if a borrower’s LTV gets too high, giving the institution time to add collateral or repay before liquidation. That kind of safety net is standard in traditional lending but rare in DeFi. For Spark, it means access to a new pool of large borrowers who wouldn’t touch a protocol without a regulated custodian in the loop.
What it could mean for DeFi adoption
The integration is still fresh, but it points to a pattern. More DeFi protocols are likely to partner with regulated custodians as institutional money flows in. RedStone’s role as an oracle provider — pulling data from multiple sources and pushing it to where it’s needed — becomes critical when the data has to satisfy both a smart contract and a bank examiner.
Whether this specific deal leads to a flood of new institutional borrowers depends on how quickly other custodians and protocols follow suit. Anchorage itself may expand the service to other collateral types or lending platforms. For now, the live LTV feeds are live for Spark users on Anchorage. No further expansions have been announced.
