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.

Sign (SIGN): Web3 protocol for trustless attestation

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.

Use copy trading the way it’s meant to be used

Before following any external signal, it’s worth spending 10 minutes to understand the rationale behind it. In trading, knowledge is your best form of compliance. Before you enter any position, ensure that you fully understand the asset you're trading, the current market conditions and the risks involved.

, never share your login credentials, and always enable two-factor (2FA) authentication. In addition, all trading activity should originate from your own account and remain under your own control.

Bybit’s systems are designed to flag irregular behavior. If your account is found to be engaging in prohibited activity, even unintentionally, you may be:

We take these steps in order to protect the broader user base and to uphold market fairness.

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.

 ecosystem forces developers to choose between security and customization, while fragmenting liquidity across isolated chains. Enter Initia (INIT), a groundbreaking protocol that reimagines blockchain architecture by seamlessly integrating 

This article examines Initia's Interwoven Stack architecture, its innovative economic features and the INIT token's utility and distribution, and considers whether this ambitious ecosystem redesign represents a promising investment opportunity following its recent mainnet launch.

 is a blockchain ecosystem that unifies Layer 1 security with customizable Layer 2 rollups through its Interwoven Stack architecture, enabling developers to build specialized application chains without sacrificing interoperability or liquidity or requiring deep infrastructure expertise.

Initia emerged in 2022 when Stanford Liu and Ezaan "Zon" Mangalji left Terraform Labs to tackle blockchain's fragmentation challenges. They later added ecosystem lead OmniscientAsian from Sino Global Capital to help create a more streamlined blockchain infrastructure.

The project quickly gained investor backing, starting with Binance Labs' pre-seed funding in October 2023. This was followed by a $7.5 million seed round led by Delphi Digital and Hack VC, then a $2.5 million community round and a $14 million Series A that valued Initia at $350 million by late 2024.

Initia aims to eliminate the traditional security/customization trade-off in blockchain by creating a unified ecosystem that allows both to coexist. By establishing a central hub for all rollups, the project combines the advantages of monolithic security with the flexibility of modularity, thereby eliminating the fragmentation that currently plagues blockchain systems.

The platform's integrated stack simplifies blockchain development with pre-built solutions that work together seamlessly. Users benefit from Initia's Universal Accounts system, which provides a consistent experience across all connected chains, eliminating the need for multiple wallets or managing different tokens for gas fees.

By introducing economic alignment mechanisms such as the 

, Initia creates an environment in which developers can focus solely on innovation in their applications. This shift away from infrastructure concerns toward product development aims to enhance capital efficiency and drive broader adoption of blockchain.

Initia fuses Layer 1 (L1) and Layer 2 (L2) technologies into a unified architecture with three distinct components. The foundation is Initia L1, built on Cosmos SDK, which functions as the orchestration layer. This base provides security, governance and interoperability.

Above this foundation, Interwoven Rollups (Minitias) provide developers with customizable Layer 2 environments, allowing them to select their preferred virtual machine (

, Move or Wasm), define unique gas token systems and implement specialized transaction ordering mechanisms. 

Binding everything together is the Interwoven Stack, a comprehensive framework that provides all necessary tools for building and deploying rollups without requiring developers to source and integrate disparate components.

The system leverages optimistic rollups through the OPinit Stack to achieve remarkable transaction speeds (up to 10,000 

) while maintaining security. Transactions processed via L2 rollups are submitted to Initia’s L1 for finalization, with data availability secured through 

Initia provides the following core features that work together to simplify development and unify the blockchain ecosystem.

Initia L1 serves as the foundational layer and central coordination hub for the entire ecosystem. Built on the Cosmos SDK with CometBFT and MoveVM, it provides essential services, including network security, governance mechanisms and liquidity solutions through InitiaDEX.

 (also known as Minitias) are flexible Layer 2 blockchains built on top of Initia L1. These rollups rely on the orchestration layer for security and data settlement, operating without native 

 while enabling advanced rollup functionalities.

Developers can customize their rollups by selecting from multiple virtual machines and defining their own gas token and fee structure. This flexibility enables application-specific optimizations and economic models, at the same time maintaining seamless interoperability within the broader Initia ecosystem.

The Interwoven Stack is Initia's comprehensive, all-in-one solution, designed to empower developers in building and deploying rollups with unmatched ease. Instead of requiring developers to research and piece together numerous components — such as wallets, explorers and 

 — the Stack provides everything needed right out of the box.

At the core of this framework is OPinit Stack, designed exclusively for optimistic rollups within the Cosmos ecosystem. It includes mechanisms for fraudproofs and rollback capabilities and supports multiple virtual machines, which allows developers to focus solely on building their applications, rather than configuring complex infrastructure.

The Vested Interest Program (VIP) is Initia's novel incentive alignment mechanism that’s designed to address common issues in multi-rollup ecosystems. It addresses the misalignment of incentives for high-activity 

 (DApps), the economic underutilization of the native token and the inefficient distribution of protocol-level incentives.

VIP programmatically rewards valuable economic activities by allocating INIT tokens to rollups that create innovative applications, and to users who perform beneficial actions. This approach ensures that rollup teams, users and token holders all share aligned interests in the ecosystem's long-term success.

 (DEX) built on the Initia L1, functioning as the central liquidity hub for all Interwoven Rollups. It features Balancer-style weighted pools for diverse asset pairs, and 

 pools for assets with closely correlated prices, ensuring an optimal trading experience.

Enshrined Liquidity is Initia's solution to the traditional dilemma in 

 (PoS) systems, whereby token holders must choose between either staking for security or providing liquidity. It allows governance-whitelisted InitiaDEX liquidity positions (INIT-TOKEN pairs) to function as staking assets alongside the native INIT token.

Users can earn both staking rewards and trading fees from a single position, dramatically improving capital efficiency. To qualify, LP tokens must include INIT as part of the pair (with at least 50% weight for Balancer pools) and receive 

 approval, which also determines reward weight distribution among all whitelisted tokens.

Minitswap eliminates the days-long waiting periods typically required by optimistic bridges when moving assets from rollups to Layer 1s. Users can instantly swap their rollup tokens for L1 assets through liquid trading pairs, creating a frictionless experience for asset transfers throughout the Initia ecosystem.

 offers a unified interface for managing assets across multiple rollups, thereby facilitating cross-chain transfers and accessing DApps. By abstracting multichain complexity into a single interface, users can navigate the entire Initia ecosystem without confronting technical barriers or fragmented experiences.

Initia's bridge technology enables secure token transfers between Initia L1 and rollups using an optimistic bridge model. The OPinit Bridge leverages Cosmos SDK modules, and operates through two key components that work in tandem to ensure system integrity.

The Executor handles token movements, output submissions and data relay, while the Challenger monitors for invalid proposals and provides security oversight. This balanced architecture delivers verifiable cross-chain communication that maintains the integrity of both L1 and L2 chains while enabling reliable asset transfers throughout the Initia ecosystem.

Initia reached a major milestone with its successful mainnet launch on Apr 24, 2025. Before then, the project had completed several critical developments, including the MiniEVM and MiniMove frameworks, the deployment of InitiaDEX and the implementation of the innovative Vested Interest Program.

The immediate post-launch phase is focusing on expanding the ecosystem by onboarding strategic partner projects across 

 and enterprise sectors. This expansion demonstrates Initia's versatility as it builds a network of interconnected Interwoven Rollups that leverage the platform's unified infrastructure.

The INIT airdrop will distribute 50 million tokens, representing 5% of the total supply, to early supporters and community members. This allocation is strategically divided across three main categories: testnet participants (89.46%), social contributors (6.04%) and Interwoven Stack partners (4.50%).

The largest portion (44.7 million INIT) is being designated for the 194,294 users who participated in Initia's public testnet campaigns, particularly those who engaged with interactive 

 activities. Additional allocations target users from partner ecosystems, including LayerZero, IBC and milkTIA holders.

Following the mainnet launch on Apr 24, 2025, eligible participants will have a 30-day claim window to secure their tokens. This airdrop serves as both a community-building initiative and a strategic token distribution to those most likely to contribute to the ecosystem's growth.

INIT is the native token of the Initia ecosystem, with a fixed total supply of 1 billion. Initial circulating supply at launch was 148.75 million INIT, representing 14.88% of the total supply. The token’s distribution is strategically designed to ensure long-term sustainability and broad community engagement.

INIT enables staking to secure the network, powers governance decisions for protocol changes, facilitates cross-rollup operations between different Minitias and provides liquidity through InitiaDEX. This utility-driven model ties INIT's value directly to ecosystem activity and adoption.

Looking to trade Initia tokens? Bybit now offers the INITUSDT Perpetual contract following the recent mainnet launch. To get started, you'll need to create a Bybit account, fund it with cryptocurrency and navigate to the 

While Initia represents a groundbreaking approach to blockchain scalability through its interwoven architecture and unified liquidity model, investors must carefully weigh its significant growth potential against relevant risk factors.

Initia shows promising potential with its comprehensive ecosystem approach and significant financial backing. In addition, growing demand for scalable blockchain infrastructure that doesn't sacrifice security or customization provides a favorable market environment. However, potential investors should 

 and consider their individual risk tolerance.

Initia revolutionizes blockchain architecture by creating a multichain environment in which thousands of appchains can coexist harmoniously through modularity and orchestration. With established financial backing and over 16 appchains already onboarded at mainnet launch, Initia could transform the way blockchain applications are built, deployed and interconnected.
