Reserve ratios for major assets like Bitcoin (BTC), Ethereum (ETH), and Solana (SOL) exceed 100%, showcasing OKX's commitment to transparency and solvency.

The report is critical for users seeking assurance about their asset security. With reserve ratios of 105% for BTC, 103% for ETH, and 102% for SOL, OKX maintains a robust over‑collateralization strategy. Most altcoins hold between 100%‑105%, ensuring a safety net for all user assets. This approach by OKX emphasizes its dedication to clear and transparent asset management.

Entities and Experts Behind the Report

OKX, founded in 2017, is recognized for its proactive transparency measures. The exchange collaborates with blockchain security firms like Hacken for authentication. These firms employ cryptographic methods such as zk‑STARKs and Merkle trees to validate asset holdings on‑chain.

In addition, OKX’s PoR data has been amplified by Wu Blockchain, a respected crypto analytics entity. Wu Blockchain published the reserve snapshot details, highlighting the specifics of BTC, ETH, and stablecoin reserves.

Reserve Figures and Asset Details

The report identifies substantial reserves for various cryptocurrencies. Bitcoin user holdings increased to 125,083 BTC, with a corresponding 105% reserve ratio driven by OKX's 131,830 BTC holdings. Ethereum holdings decreased by 35,011 ETH to 1.704 million but still maintain a 103% reserve ratio.

Stablecoins such as USDT saw a drop in user holdings by 2.56% to 9.4 billion, while maintaining a 105% reserve ratio. Meanwhile, USDC experienced a 1.17% decline to $1.14 billion, aligning with a 100% reserve ratio, showcasing comprehensive asset management by OKX.

Regulatory Compliance and Historical Context

Currently, no new regulatory or funding announcements are tied to OKX's latest PoR release. However, in 2025, the exchange paid a $505 million fine for previous AML violations. This separate incident emphasizes the importance of OKX's current transparency initiatives.

The firm consistently publishes independently audited reports, a critical strategy meeting global regulatory demands for transparency. These actions reinforce OKX's commitment to maintaining trust within the cryptosphere following historic transparency shortfalls in the industry.

Impact on the Crypto Ecosystem

OKX's regular publication of PoR reports plays a pivotal role in setting industry benchmarks. Despite the absence of new funding or institutional partnerships in this release, its consistent disclosures have historically stabilized its market standing. The transparency in reserves contrasts with other exchanges that have faced crises following their opaque practices.

By ensuring the verifiability and security of its reserves, OKX benefits its retail and institutional clientele. While significant market events like the FTX collapse cast shadows on the industry’s reliability, OKX's ongoing focus on asset transparency positions it favorably amongst crypto exchanges.
