Our weekly crypto derivatives analytics report delves into macro events; the current state of crypto and trading signals from spot trading volume; and futures, options and perpetual contracts.

After mostly trading sideways at the end of April 2025, a US-UK trade deal sparked a crypto rally. BTC surged past $100K for the first time since February, but it’s ETH's performance that captured the derivatives market's attention. 

A 23% increase in ETH's spot price led to an inverted term structure and a spike in front-end volatility. The put/call skew for ETH shifted from a bearish bias to a nearly 10% skew toward OTM calls. Other sentiment indicators, such as perp funding rates and futures yield, also supported the rally. In contrast, while BTC's funding rates and skew have increased, its implied volatility remains low at 40%, over 30 points below ETH's 7-day implied volatility.

Please check out the report’s highlights.

ETH’s record performance since 2021 was propelled by positive term structure

ETH has significantly outperformed BTC and the top 10 cryptocurrencies, marking its largest single-day gain since May 2021. The options market has reflected this enthusiasm, with implied volatility for short tenors rising sharply and inverting ETH’s term structure, thus contrasting with BTC's muted, positively sloped structure. The 7-day tenor for ETH is now trading at a 33-point premium over that for BTC. 

While puts dominate BTC's open interest, ETH is seeing the opposite trend. On May 8, 2025, options volumes surged over $120M, more than double the typical monthly volume, with $60M more in calls than puts. ETH now boasts a positive futures curve and funding rates, as well as a strong skew toward OTM calls.

ETH sees exceptionally bullish put/call skew

ETH's substantial outperformance in the current crypto rally has led to bullish sentiment in its derivatives markets. Funding rates have surged, futures yields are strongly positive and the put/call skew has shifted significantly toward OTM calls, now close to 10%. This starkly contrasts with early April, when the skew was 20% toward OTM puts. Although ETH has underperformed (relative to BTC and other "ETH killers"), it has rebounded in this rally, with the ETH/BTC ratio rising after spending most of the year declining.

Open interest for Bitcoin options increased, with implied volatility remaining suppressed

The announcement of the new US administration's first trade deal, nearly 30 days into Trump's 90-day tariff pause, jolted crypto markets, pushing BTC back up above $100K. Surprisingly, implied volatility has remained suppressed, failing to invert BTC's term structure, with front-end volatility trading at around an 18-month low of 35-40%. On May 8, 2025, options volumes surged, with call volume reaching $189M, reversing last week's trend of higher put volumes. Meanwhile, open interest rose steadily to exceed $300M, the highest level this month, but remains significantly larger for puts than for calls despite the price increase.

Compliant trading means following platform rules and avoiding manipulative behavior. Learn more about how you can trade responsibly and compliantly on Bybit.

Crypto trading has come a long way from what used to be the domain of institutional players, and is now open to almost anyone with an internet connection. It’s easier than ever to buy and sell digital assets, try new strategies or build a portfolio from scratch all within minutes.

But with that level of access comes responsibility. As more people join the market, the need for fairness and accountability has become even more important. This isn’t just about price charts or profits — it’s about keeping the playing field level for everyone involved.

At Bybit, we take that responsibility seriously. We're here to offer the tools, safeguards and education you need to help you trade responsibly and to protect the platform from misuse.

This article describes what it actually means to trade compliantly, why it matters — and what can happen if things go off course.

Compliant trading means playing fair, following the platform’s rules, staying within the boundaries of what’s allowed and avoiding anything that could unfairly affect the market.

It’s not about avoiding risk: it’s about knowing what you’re doing, using official tools the right way and making sure your trades aren’t causing harm to yourself or others.

In short, compliant traders don’t just focus on their P&L — they understand that how they conduct themselves while trading matters. Responsible trading protects their accounts, keeps the platform stable and builds long-term credibility in the crypto ecosystem.

Why does responsible and compliant trading matter?

It’s easy to assume that compliance is only something platforms or regulators need to worry about. But in reality, every trader plays a part. When someone attempts to exploit the system — for example, by coordinating mass trades through off-platform channels — the consequences can ripple across the entire market.

In extreme cases, irresponsible trading behavior can:

And if the trades in question are linked to coordinated action, use of fake accounts or external bots? That opens the door to account freezes, compliance reviews and, in some cases, permanent suspension.

Bybit has a responsibility to act when the system is being abused — not just for legal reasons, but in order to protect honest traders.

Common examples of noncompliant or risky behavior

Some traders join Telegram groups or online communities in which KOLs (key opinion leaders) give out coordinated trading instructions (for example, “Buy token A now, sell it in an hour”). This practice isn’t just risky: it often involves a small number of insiders benefiting while the majority end up with losses.

When many people follow the same instruction all at once, it can artificially inflate the price of a low-liquidity token. The KOLs then exit at the top —while others are left with falling prices and unexpected liquidations.

Such a textbook case of market manipulation violates our Terms of Service and, depending upon jurisdiction, could violate financial laws.

Using bots or unverified trading strategies

Some Telegram groups may seem convincing, but trades coordinated off-platform are often unverified and may serve someone else’s agenda. 

 programmed to front-run trades, mimic pump-and-dump strategies or follow unverified signals can trigger compliance red flags and may lead to account restrictions.

Bybit does not support trading bots from unverified sources. They can also trigger flags in our monitoring systems, which may result in account suspension.

Using another person’s account or sharing login credentials — even if it’s with a family member — goes against both Bybit’s policies and global 

(AML) rules. It also opens the door to fraud, loss of funds and irreversible penalties.

Tips for responsible and compliant trading on Bybit

The good news is that there’s a better way to trade — responsibly, safely and with confidence, starting with the right tools, mindset and habits.

Being compliant doesn’t mean missing out on opportunity. In fact, it’s the opposite. It means you’re using the platform the way it was designed, with safeguards, transparency and trust. Shortcuts might look appealing in the short term, but they rarely end well. The most successful traders on Bybit are the ones who understand risk, stay informed and trade with integrity.

Take the time to learn and use the tools available to you. And remember: protecting your account starts with choosing how you’ll trade.

How to trade compliantly and responsibly on Bybit

Discover how DAI evolved into USDS under the Sky protocol—unlocking passive rewards, scalability, and a new era of DeFi with Sky Token Rewards.

In September 2024, MakerDAO, a pioneering 

 (DeFi) protocol, underwent a significant transformation by rebranding itself as 

 (SKY). This rebranding was part of the project's comprehensive strategy to enhance scalability, user engagement and regulatory compliance. The major changes that came with the rebranding include token upgrades, whereby the platform’s stablecoin, Dai, was upgraded to USDS (Sky Dollar) while the 

Let’s take a deeper look at USDS and its role on the Sky platform.

USDS (United States Dollar Sky) is the upgraded version of the Dai stablecoin, launched under the newly rebranded Sky protocol (formerly MakerDAO).

 Like DAI, USDS is a decentralized, overcollateralized stablecoin designed to maintain a 1:1 peg with the US dollar.

However, USDS significantly improves scalability, user incentives and regulatory positioning, making it a next-generation solution for DeFi.

One of the standout features of USDS as a stablecoin is that it creates 

 opportunities for its investors. With USDS, you can access the Sky Savings Rate (SSR) feature, which allows you to participate in the Sky ecosystem's governance by accumulating Sky Token Rewards (STR) (presented in the form of SKY tokens).

SSR also features a variable automated token accumulation feature, whereby you receive 

 to the SSR program. This passive earning potential offers a major advantage for users seeking yield without complicated 

Sky uses a dynamic model that adds USDS to the SSR pool every few seconds. Over time, the value of sUSDS in the particular pool increases. You can then opt to redeem your sUSDS for USDS, and receive the USDS you initially supplied in addition to the USDS equivalent you’ve accumulated.

These rewards serve as an incentive mechanism, enabling users to passively grow their holdings while supporting the health and stability of the Sky ecosystem.

Upgrading from DAI to USDS is straightforward. Users can visit Sky.money and initiate the upgrade directly through a noncustodial, user-controlled process.

The platform provides a simple interface on which users connect their wallets, exchange their existing DAI for an equal amount of USDS and instantly become eligible for yield accumulation and other Sky ecosystem benefits. There are no fees for the upgrade, and users retain full control of their assets at all times.

USDS isn’t just a stablecoin; it’s an evolution of DeFi money. With passive earning through Sky Token Rewards and a smooth, secure upgrade path, USDS sets a new standard for the way decentralized stablecoins can deliver value and financial empowerment to users worldwide.

USDS and DAI are both decentralized stablecoins originally developed under the MakerDAO ecosystem (now Sky). While they share the same core principle — overcollateralization and the maintenance of a 1:1 peg with the US dollar — USDS represents a major evolution of DAI, introducing additional incentives designed to enhance user experience, scalability and regulatory alignment.

DAI has long been a favorite in the DeFi ecosystem, allowing users to generate stablecoins by locking up crypto collateral such as 

. DAI features a savings program, the DAI Savings Rate (DSR), from which people can earn 

 (sDAI). While the DSR program is still running, upgrading to USDS lets you earn two types of rewards through the SSR program: sUSDS tokens and Sky Token Rewards (STRs).

In addition, USDS is well positioned to meet regulatory requirements, aiming for broader mainstream adoption while maintaining decentralization.

Below is a comparison table between DAI and USDS:

USDS is backed by collateral that’s deposited in Sky vaults by borrowers. In return, the reserves for these vaults are backed by three main assets: 

With a market cap of over $8 billion, USDS is the currently third-largest stablecoin after 

 is more complex than that of typical stablecoins, as it includes liquidation mechanisms and a peg-stability module. However, an audit of USDS’s smart contract in September 2024 didn’t report any significant risks with the stablecoin. Notably, S&P Global Ratings 

 of 4 out of 5, indicating constrained ability to maintain its peg under certain conditions. 

​Additionally, the proposal to include a freeze function for USDS, which bestows upon the Sky protocol the power to halt USDS transfers between wallets, has sparked heated discussions within the community, highlighting the ongoing conundrum of balancing security measures with principles of decentralization.

The evolution of DAI to USDS marks a major leap forward for DeFi. By combining DAI's trusted and overcollateralized model with additional passive earning opportunities through Sky Token Rewards, USDS empowers users to enjoy greater financial benefits with less complexity.

The streamlined upgrade process and stronger regulatory positioning set the stage for broader adoption and a more resilient future. As Sky continues to build, USDS represents more than just a stablecoin — it’s the foundation of an open, accessible and more rewarding financial ecosystem for everyone.

Clipper is a DEX specializing in buying and selling blue-chip tokens. Its unique architecture can provide better pricing for popular crypto, such as ETH.

When it comes to purchasing crypto for investments, the exchange you choose matters. Certain exchanges can offer more favorable prices or lower fees than their competitors. One new decentralized exchange,

, hopes to offer their users big savings and reduced market manipulation. In addition to being a crypto exchange, the network behind Clipper also offers some appealing DAO and token staking services. 

Does the Clipper network actually work, and should you try it? Here's what you need to know.

Clipper is a decentralized cryptocurrency exchange (

) that specializes in buying and selling 

. Its unique architecture can provide more favorable pricing for popular cryptocurrencies, such as 

Clipper and AdmiralDAO are part of a project initially launched by Shipyard Software. The

 consists of several developers and crypto experts. Founder/CEO Mark Lurie has also worked on other blockchain startups, such as Codex, and the team's Chief Scientist/CTO, Abe Othman, previously worked with Vitalik Buterin on the 

Shipyard Software's goal is to create customized exchanges for every type of crypto trader. While there are a lot of other exchanges available, Shipyard’s founders realized there was a demand for exchanges that use special features to assist with specific crypto trades. Clipper is just one of several exchanges that Shipyard Software runs.

The Clipper DEX and its governing DAO have specifically been created to optimize blue-chip 

. Clipper gets its name from a type of 19th-century ship, called a 

, that helped to revolutionize trade by increasing shipping speed. This basic concept of enhancing profitability by prioritizing efficiency has greatly influenced Clipper's design.

Clipper's aim is to facilitate blue-chip trades while optimizing liquidity provider profit. What does this mean for the average user? First of all, Clipper tries to solve the problem of excessive 

 and unstable prices. When trading blue-chip tokens like ETH and 

, many other exchanges perform pricing computations on-chain and then pass on the costs to the traders. Clipper's unique design is meant to save users money by reducing on-chain computations.

Another major goal of Clipper is to increase decentralization. Centralized crypto companies have

 due to their lack of privacy, the amount of trust the user must place in the platform and the security risks that come with centralization. By using a decentralized autonomous organization, Clipper hopes to solve some of these issues. They put power into the hands of users and ensure that no single party can manipulate the exchange.

In addition to making things better for traders, Clipper also strives to help liquidity providers, who supply tokens in exchange for fees that are a percentage of the total purchase. Since asset prices fluctuate, liquidity providers can end up losing more money than they make in a transaction. This happens when one contributes to a liquidity pool and the token values deviate from the initial prices. This is known as 

, and it's a major issue in the industry. Clipper's unique algorithm avoids impermanent loss, so it provides more money to liquidity providers and incentivizes more people to provide liquidity for the exchange.

The main mechanism behind Clipper is its method of pricing, called Formula Market Maker (

). This special pricing formula combines real-time prices from oracles and token ratios to create highly accurate pricing quotes. It also employs

a variety of complex mathematics, including an 

FMM provides many advantages for Clipper. Since prices are so accurate, liquidity providers are less likely to encounter impermanent loss when they provide tokens. In addition, Clipper's unique formula allows it to calculate pricing data off-chain, and go on-chain only to verify this information. By moving calculations off-chain, Clipper saves users more money. Its formula further verifies any variation in pricing data between on-chain and off-chain calculations to ensure all data remains as accurate as possible.

Although Clipper’s DEX is fairly small and specialized as compared to more popular crypto exchanges, it still manages to offer several helpful features.

Clipper's DEX offers several different types of swaps. Since the site was originally designed for retail traders, it incentivizes smaller trades and only lists blue-chip tokens known for being reliable investments. With the 

 system, people can exchange various cryptos without having to pay excessive fees. Current tokens supported on Clipper Swap include ETH,

 are single-sided pools that offer especially low trade fees and flexible swapping. People can enter any asset into a Cove and then 

 in the form of the underlying asset and LP tokens. This helpful system facilitates boundless swapping and extremely cost-effective trades. Clipper Coves hasn’t officially launched yet, but users can join the Clipper community to get the latest news.

 their system. After creating a working platform, they conducted a soft launch with $1 million in liquidity to test the system, and an official launch that opened the exchange and liquidity pools to the public. Clipper's road map has changed a little over the years. They originally focused on retail traders making small trades, but have expanded their project to include larger trades as well.

Now that Clipper has a workable platform and supports several trading pairs, their next goal is to fine-tune their DAO. Turning over control from the creators to the community takes time, so Clipper is in the process of welcoming new members, creating community guidelines and finalizing decision-making mechanisms. The platform hasn't announced many plans for what’s to come after getting the DAO up and running, but some users speculate they’ll be working to expand their exchange to support even more cryptos.

 token with a total supply of 1 billion coins. This current supply is a soft cap, and more may be released as needed. Due to the way the tokens are set up, the DAO can also vote to 

 as needed. SAIL tokens are distributed in the following manner:

Just released on Aug 22, 2023, SAIL is still an extremely new token without a lot of pricing data available. When the token was first released, its price was $0.01390500, which is so far its all-time high. It then dropped to its current price of $0.00700693 (as of Aug 24, 2023).

Since SAIL is still so new, it's difficult to tell exactly what will happen to its price. The token is only listed on a few exchanges. Furthermore, the lack of a hard cap for token supply could cause some inflation issues that might drive prices down. However, Clipper has generated positive press with its move to welcome traders (besides retail traders) and its DAO launch. If the project continues to gain hype, SAIL prices could potentially rise. Since SAIL is a governance token with uses beyond price speculation, it retains some inherent value, no matter what happens.

If you want to buy SAIL without having to stake liquidity in Clipper, Bybit is currently one of the only exchanges listing the token. This reliable exchange offers the token as a SAIL/USDT Spot trading pair. Purchasing crypto through Bybit is fast and simple. Simply

So far, SAIL doesn't seem like it's going to generate unusually impressive profits. Unlike many wildly popular crypto trends, SAIL doesn't have any notable investors, groundbreaking promises or newsworthy price swings. However, it's still a solidly reliable project that could be quietly successful. Shipyard Software has done well with past projects, and Clipper does offer users the potential to reduce impermanent loss. 

Those looking for an investment with slow-yet-steady growth might want to consider SAIL. It's neither high-risk nor low-risk, so this investment may be a great way to add some diversity to your portfolio.

With its ability to provide low fees to traders and improved profits to liquidity providers, Clipper is an exchange that benefits all participants. The addition of a DAO governance system and a unique algorithm to calculate token prices helps it stand out from competitors. Even those who don't plan on using the exchange may want to check out the project’s new SAIL token.
