CryptoQuant, a company that studies crypto markets, released its annual Exchange Leader report for 2025. This report looks at how much information exchanges share about their reserves and how they trade. One big finding stands out: KuCoin has the highest proof-of-reserves (PoR) transparency score among the major crypto exchanges. KuCoin scored 96.7 out of 100, the top score in the dataset.
PoR stands for proof of reserves. This is a way for a crypto exchange to show it actually holds enough cryptocurrency assets to cover the balances of all customers on the platform. In other words, it is a check to see if a company really has the crypto it says it has in its system. A high PoR score helps traders feel confident that customer funds are safe and available if many users want to withdraw at once.
The report ranked exchanges based on three things: reserves (how much crypto the exchange has on hand), trading activity (how much people are buying and selling), and derivatives activity (special types of trading that use contracts rather than the actual coins). It looked at data from 2025 to see which platforms were most transparent about their reserves and how they operate.
KuCoin’s PoR score comes from its monthly PoR framework. This framework allows users to check balances using a method called a Merkle-tree inclusion tool. A Merkle tree is a special way to verify that a specific balance is part of a larger set of balances without showing every balance. You can think of it like a receipt that proves you own a coin without showing all the other people’s balances. The exchange also publishes wallet addresses and receives third-party attestations from a security firm called Hacken. You can think of attestations as independent experts confirming that the information is correct.
CryptoQuant said KuCoin has published more than 39 monthly reserve reports in a row. The most recent report at the time was published on February 6, 2026. For the assets that KuCoin disclosed publicly, the reserve ratios were above 100%—meaning the exchange showed more assets than customer balances for those assets. This is a sign that, at least for the assets they disclosed, holders could be paid back in full if everyone wanted to withdraw at the same time.
Bybit, another well-known exchange, ranked second in transparency with a PoR score of 93.2. Like KuCoin, Bybit benefits from regular PoR disclosures and Hacken attestations. This shows a steady pattern of sharing reserve information and having independent verification.
Kraken, another long-standing exchange, is listed in the A tier. However, its score was affected by its use of a quarterly reporting cycle, which is less frequent than the monthly reporting practiced by KuCoin and Bybit. In the eyes of CryptoQuant, more frequent reporting tends to improve a PoR score because it gives a more up-to-date picture of reserves.
Not all big exchanges performed as well in this PoR category. Binance received a score of 75.2. The score reflects that Binance discloses many wallet addresses and provides user balance verification tools, but it did not publish a full independent audit covering its entire balance sheet. Coinbase, the United States–based exchange, scored much lower at 44.3. This lower score is largely because Coinbase does not publish comprehensive wallet address mappings and does not provide on-chain verification for customer balances. In short, Coinbase shares less detailed information that would allow independent verification of every customer balance.
The transparency ranking is just one part of CryptoQuant’s Exchange Leader Index. This index measures platforms using six pillars: trading volume, reserves, PoR transparency, trading mix balance (the split between different kinds of trades), volume growth, and reserve growth. When CryptoQuant combines all six pillars, the top spots for the 2025 year went to MEXC, Binance, and Bybit.
Beyond PoR, the report also looks at how exchanges run their trading around the world. One interesting finding is that many large exchanges now see most of their activity in derivatives markets rather than in simple spot trades. Derivatives are contracts that derive their value from an underlying asset. Perpetual futures contracts are a common type of derivative in crypto markets. CryptoQuant found that on several exchanges—MEXC, Bybit, Bitget, Binance, Gate, and Coinbase—between 70% and 90% of their total trading volume came from these derivative contracts rather than from buying and selling the actual coins in the open market.
KuCoin, on the other hand, sits with a more balanced mix. It has a sizable amount of trading in both spot markets (the actual buying and selling of cryptocurrencies) and derivatives. CryptoQuant grouped KuCoin with HTX and Kraken as examples where both spot and derivatives contribute significant volumes instead of one side dominating.
In terms of overall trading size, Binance remains the largest exchange. It processed about $32.4 trillion of annual trading volume in 2025. Of that total, roughly $25 trillion came from derivatives, while about $7 trillion came from spot trading. This shows how big the derivatives market has become in the crypto world. Derivatives trading allows people to speculate on price movements or hedge risk without owning the actual coins.
Different exchanges grew at different speeds during 2025. Gate, for example, recorded the fastest growth in derivatives activity, with perpetual futures volumes rising by more than 400% year over year. Coinbase also posted large percentage gains in some areas after it completed its acquisition of Deribit (a major crypto derivatives platform) and after it introduced Solana-based decentralized exchange trading. MEXC also saw a big rise in its spot trading volumes during the same period. These changes show how competition among exchanges can shift quickly as new services and products are added.
Overall, the CryptoQuant report highlights how important transparency is to traders. When an exchange publishes regular, independently verified reserve information, traders can have more confidence that their funds are safe. It also helps users compare different platforms on a fair basis using the same criteria. However, the report also notes that no single number can tell the whole story. Some exchanges might have strong transparency in the assets they choose to disclose, but others may disclose less information overall. Traders should look at the full set of data, not just one score, to understand an exchange’s risk and reliability.
CryptoQuant publishes its findings as part of the Exchange Leader Index, a broader effort to rank and compare exchanges across multiple factors. The goal is to help traders and investors make smarter decisions about where to trade and hold assets. The 2025 results show a mixed picture: a few exchanges lead in transparency and balance, while others still have room to improve in how openly they share reserve information and how often they report it.
The full report and its methodology are intended to give a clearer view of how major exchanges operate beyond simple price quotes or daily trading numbers. As the crypto market grows and becomes more complex, transparency about reserves and the health of an exchange’s balance sheet becomes more important to the people who use these platforms every day. For now, KuCoin’s high PoR score marks it as a standout in transparency among large exchanges, according to CryptoQuant’s 2025 findings.
For readers who want to explore the numbers and the rankings more deeply, CryptoQuant’s Exchange Leader Index presents a multi-dimensional view. It uses six pillars to score exchanges. These pillars are trading volume, reserves, PoR transparency, trading mix balance, volume growth, and reserve growth. Each pillar adds a piece to the overall picture of how a platform performs over the year. In 2025, the top three were MEXC, Binance, and Bybit, with KuCoin earning the top PoR transparency score within the reserve and transparency category.
In summary, the key takeaway is simple: KuCoin was rated as the most transparent about its reserves among major exchanges in CryptoQuant’s 2025 report. This conclusion came from looking at how often it reports reserves, how it shares information publicly, and how independent testers verify that information. For traders, this is useful. It helps them decide where to trade or store their assets, especially if they want more assurance about the safety of their funds. Yet it’s important to remember that transparency is only one part of an exchange’s safety. Users should also consider other factors such as security practices, user experience, fees, and regulatory status when choosing where to trade.
