Ledn Publishes Industry-First Monthly Loan Book and Proof of Reserves Data

Ledn, one of the world’s largest bitcoin lenders, announced its Open Book Report, a reserves transparency benchmark designed to expose the kind of risk that caused the 2022 FTX-driven crypto crash. 

According to a press release shared with Bitcoin Magazine, “Traditional lenders (including Citi, JPMorgan, Wells Fargo, BNY Mellon, Schwab, and Bank of America) are reportedly entering the space amid a regulatory vacuum in terms of rehypothecation practices and proof of reserves.” With the passing of the GENIUS Act, which greenlit treasury-backed stablecoins, Wall Street now has a road to service the crypto market and even upgrade its own rails and infrastructure. 

But there are still those who call for clearer regulatory structure for crypto counter parties, Ledn points out that “Global rules on crypto capital requirements & proof of reserves remain in flux, with the US and UK refusing to implement Basel’s proposed framework,” adding that “IOSCO is pushing regulators to hold crypto custody and lending to the standards of traditional finance, yet almost no institution has disclosed how bitcoin collateral is managed, whether it’s rehypothecated, or what happens in a liquidation scenario.” 

John Glover, Chief Investment Officer at Ledn and former Managing Director at Barclays, explained that “If lenders do not have to disclose how they use client collateral, the clients become the leverage. We saw what happened when BlockFi, Celsius, and Voyager operated in the dark. The difference now is that the balance sheets are bigger.” He warned that “This is how we get a 2022-style lending crisis at institutional scale.”

Ledn’s Open Book Report, launched today, showcases “the industry’s longest-running Proof of Reserves,” according to the press release. The report exposes Ledn’s BTC loan book, collateral levels, and aggregate loan-to-value ratios. According to the report, the Network Firm LLP, a U.S.-based certified public accounting firm, independently audited & confirmed that 100% of collateral is held in custody.

The report also reveals “$868 million in outstanding BTC-backed loans, with 18,488 BTC in collateral posted, held 100% BTC in custody; all BTC collateral is held in on-chain addresses and/or custodial accounts.” Ledn’s average loan-to-value ratio stands at 55%, an aggregate LTV well below industry liquidation thresholds. Since 2018, the company has funded “$10.2 billion in lifetime loans across 47,000 originations.”

This framework looks to move the industry past one-off snapshots—starting with monthly disclosures and laying the groundwork for more continuous, real-time transparency over time. Unlike self-reported wallet addresses, Ledn’s approach combines monthly reporting on loan book metrics—including outstanding loans, collateral posted, and average LTV—with reporting from The Network Firm LLP. Ledn also maintains Proof of Reserves attestations on a semiannual basis (every two quarters), confirming that assets exceed client liabilities, with “Merkle tree methodology” enabling clients to confirm their balances were included.

While some companies have announced “proof of reserves” by publishing wallet addresses, Glover argues this falls short. “True transparency requires independent reporting, regular updates, and methodologies anyone can check,” said Glover. “Clients shouldn’t have to take anyone’s word for it.”

Ledn recently received a strategic investment from Tether and has an impeccable track record of protecting client assets across its loan originations, surviving the 2022 crypto lender crisis, and at least one other bear market before that. 

The press release warns that “as traditional financial institutions accelerate their entry into bitcoin-backed lending, Ledn’s Open Book Report establishes the baseline against which these new entrants should be held, before regulators mandate it.”
