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.

Positive sentiment around potential US trade deals has fueled a sixth straight day of gains in risk-on assets. Bitcoin, boosted by this sentiment and its own drivers, such as strong ETF inflows and regulatory progress, has outperformed gold and equities, rising 14% over the past month and consolidating at $94K. Bitcoin’s implied volatility has decreased significantly, while realized volatility has stabilized above 30%, a level that’s been its floor for the past 18 months.

Please check out the report’s highlights.

Perp at months’ high; traders not yet all-in

After rallying from $75,000 to over $95,000 in early April, Bitcoin has traded sideways at around $94,000 this week. Open interest remains stable for April, near all-time highs at $8B, while trade volumes have decreased to $10B per day. Lower trade volumes correlate with lower realized volatility, and perp positioning suggests that traders are waiting for another rally before committing to major positions, mindful of recent sell-offs.

Bitcoin volatility declines to 18-month low

Bitcoin’s volatility has declined, nearing a previously held floor of 35–40%, a level from which it has consistently rebounded over the past 18 months. Implied volatility has followed a 10-point drop in realized volatility to just above 30%, the floor of its 18-month range. Options activity shows a preference for puts, as BTC’s spot price is remaining stable. Volatility smile skews favor out-of-the-money calls, particularly for long-term options, while short-term options are nearly neutral.

BTC volatility smiles skew toward OTM calls

Bitcoin's volatility smiles now favor out-of-the-money (OTM) calls across all tenors, recovering from a put-call skew that strongly favored puts earlier in April. Ether is showing a similar recovery at short tenors, but longer-term skew remains slightly bearish. While ETH funding rates are positive, longer-term option smiles are skewing toward puts, thus presenting mixed sentiment. For BTC, derivatives markets are indicating clearer bullish signals, including positive funding rate spikes, positively sloped futures yields and a skew toward OTM calls.

Discover how USDY, a yield-bearing stablecoin from Ondo Finance, offers secure, regulated returns backed by US Treasuries across multiple blockchains.

, which are crypto assets pegged to a major fiat asset, have gained tremendous popularity and are helping investors deal with the typical volatility of the market. For many years, stablecoin cryptocurrencies have been used for payments, principal value storage, B2B transactions and more. However, traditional stablecoins have always lacked the ability to generate yield. These assets are fixed at a certain rate (e.g., $1) and, due to inflation, they don’t protect against your funds’ value erosion. 

 have started to gain traction over the past several years. These "new generation" stablecoins, unlike their traditional counterparts, not only provide rate stability but also generate yields, growing your investment over time. One of the leading assets among yield-bearing stablecoins is US Dollar Yield (USDY), issued by Ondo USDY LLC, part of 

Backed by low-risk traditional finance (TradFi) reserves, USDY generates yields and is a fully composable asset that can be used throughout the DeFi ecosystems of multiple blockchains. The reserves and issuance of the stablecoin are also subject to high regulatory controls. In the world of yield-bearing stablecoins, USDY is among the top choices in terms of popularity, regulation and security.

What is the Ondo US Dollar Yield (USDY) Token?

 (USDY) is a yield-bearing stablecoin offered by Ondo USDY LLC, part of the Ondo Finance DeFi solutions provider. 

USDY’s value tracks that of the US dollar, and it’s backed by Treasury bills and demand deposit reserves. The coin issuer’s parent company, Ondo Finance, specializes in institutional-grade crypto solutions. Ondo aims to make on-chain institutional-grade finance tools and infrastructure accessible to anyone.

USDY was launched in August 2023. As of April 2025, the stablecoin has become available on 

 — a level of multichain coverage that few other stablecoins can match.

While USDY’s price tracks the US dollar’s, its rate is typically somewhat higher than $1 because yields earned by each unit of the stablecoin are added to it, increasing its nominal value.

 (RWAs), primarily Treasury bills, although some portion of the reserves may also be represented by bank demand deposits. Both of these financial asset types are considered cash equivalents.

To ensure the Ondo ecosystem's security, Ondo backs each $100 equivalent of USDY with reserves worth $104, maintaining a 4% overcollateralization rate at all times.

Ondo Finance takes the transparency of USDY seriously. The company has established a bankruptcy-remote mechanism, with a separate corporate entity controlling the issuance and oversight of the stablecoin in various ways, including a board of directors with an independent director, and segregation of assets and reporting from Ondo.

USDY is a fully composable asset that can be used in the DeFi ecosystems of its host blockchains for various purposes, such as collateral, 

USDY provides several significant benefits for its holders. First, it allows eligible individual and institutional investors to earn dollar-denominated yield. This is in contrast to traditional stablecoins, which provide no yield opportunities at all. While other yield-bearing stablecoins also generate returns for holders, some of these pay the yields in volatile cryptocurrencies, rather than high-quality assets.

Thanks to its dollar peg, USDY offers both yield and relative stability. Additionally, it’s fully composable, creating opportunities for use across various DeFi protocols. USDY is available on seven blockchains, providing access to more DeFi opportunities than most yield-bearing stablecoins.

The coin may also be used for passive holding, growing in value over time as yields accrue. In this capacity, USDY represents a good low-risk, on-chain investment opportunity.

Finally, USDY’s overcollateralization and backing by high-quality TradFi assets, Treasury bills and demand deposits make it one of the most secure yield-bearing stablecoins on the market.

How does Ondo US Dollar Yield (USDY) work?

Individuals and institutional entities need to undergo an onboarding process to acquire USDY, during which they submit relevant identity, legal and tax documents. Ondo diligently applies 

 (AML) checks in order to adhere to US securities laws, the Investment Company Act of 1940 and other relevant regulations.

US and UK residents cannot apply to buy USDY, although you may be eligible if you’re a US or UK citizen and reside abroad.

If your application is approved, you can be issued USDY 40 to 50 days after your initial deposit date, although you’ll start earning yield from the first day of your investment. The minimum amount for investment or redemption is $500. You can buy USDY from Ondo using the 

 stablecoin. US dollar wire transfers are also supported for amounts over $100,000.

Redemptions are only transferred in US dollars to bank accounts outside the US. You can redeem your USDY investment at any time, and the typical timeline to receive your funds is about 2–3 business days from the date of your request.

USDY accrues yield daily. The stablecoin’s yields are structured not to incur any US federal tax obligations. Ondo doesn’t charge any performance or management fees for USDY yields. However, the company earns income from a portion of yields generated by the underlying assets backing USDY.

As noted earlier, USDY’s yields accrue to each unit of the token. Therefore, the value of one USDY is usually above $1. For instance, the average value of USDY as of the time of this writing (Apr 30, 2025) is $1.11.

For investors who prefer a fixed $1 rate for the stablecoin, Ondo offers the rebasing version, called rUSDY. Yields for rUSDY are paid to your wallet in the form of additional tokens by increasing the supply of the crypto, while the principal remains at (or very close to) $1. This is known as rebasing. USDY and rUSDY are freely convertible between each other.

The rebased version of the coin might be useful to those who need to ensure rate stability (for example, for B2B payments of agreed-upon contractual amounts) while also earning yields from their investments.

 as a swap pair with the USDT stablecoin.

USDY boasts numerous benefits for investors — low-risk yields from high-quality traditional assets, wide multichain coverage, regulatory compliance, transparency, composability and rate stability. The combination of all these benefits is quite rare in the crypto market, and the investor community is definitely taking note: USDY is already the third-highest-ranked yield-bearing stablecoin by market cap as of late April 2025. 

Since the yield-bearing stablecoin niche is expanding, the advantages of the USDY are likely to attract further interest, both among the institutional crowd and with individuals keen to access high-quality, institutional-grade crypto products.

 became the predominant narrative in the crypto market in 2024, a trend that’s likely to continue in 2025. New and emerging projects — such as 

 — have shown glimpses of what’s possible when these two emerging technologies collide. 

As AI technology spreads, the privacy of the model that’s training data sets becomes an important issue. Phala Network offers a solution to this pressing concern.

 is a cloud computing platform that runs AI models and programs inside a secure module called a trusted execution environment (TEE). TEEs are isolated environments that guarantee the code and data loaded inside are protected from external observation or tampering. This method allows Phala to execute sensitive information like AI model training and inference without compromising the privacy of the data or the integrity of the process. 

Through this innovation, Phala has managed to carve out a niche as the go-to AI coprocessor on web3. In 2024, it hit several notable performance metrics, as detailed below:

To understand Phala’s strong growth in the AI sector, let’s delve deeper into its hybrid architecture and discover what sets it apart from its competitors. 

What Is a Trusted Execution Environment (TEE)?

Phala uses a TEE-blockchain architecture that combines the strengths of TEEs and blockchain technology to create a secure, scalable and efficient system.

TEE refers to a segregated area of hardware that’s protected from the rest of the system using encryption. Data in the TEE can’t be read or tampered with by any code outside that environment; only trusted applications within the environment can access and modify the data. This architecture has been used by governments, enterprises and other cloud service providers to enable secure handling of confidential information on traditional Web 2.0 mediums. With Phala’s integration of TEE to blockchain, web3 DApps have also gained access to the same level of security. 

Within this hybrid architecture, once the TEE handles secure, 

 computations, the blockchain is used to verify their integrity and make sure the computations have been executed as intended. This hybrid approach allows Phala to combine the trust of blockchains with the privacy of TEEs, thereby addressing the limitations of both systems. 

Since this approach is similar to that of 

 (ZKPs), comparisons between the two are inevitable. While TEE proofs and ZKPs share the same goal of ensuring computational integrity and verifiability, they differ in their construction and operation. The computational cost of generating a TEE proof is significantly lower than for a ZKP. In addition, the sizes of ZKPs are also larger than those of TEE proofs, which increases the cost of on-chain verification. Therefore, TEE-based verification methods are often faster and cheaper than ZK-based methods.

Benefits of a Trusted Execution Environment–Blockchain Hybrid

: TEEs ensure that sensitive data such as AI inference remains protected from unauthorized access.

: Blockchain is used to authenticate and verify the correctness of computations performed within TEEs, ensuring that results are trustworthy. 

: Compared to ZKPs, TEEs are faster and cheaper, making them ideal for large-scale computations like those required for artificial intelligence.

: By offloading computations off-chain, the hybrid architecture reduces the load on the blockchain and improves the scalability of the underlying chain.

Phala uses a 3-tier model to provide security, privacy and transparency. The image below depicts the inner workings of the network:

 ensures that all hardwares, such as GPU and CPU and software (TEE) are secure and trustworthy. 

 provides a secure environment for the DApps to run on. 

 is used to ensure the authenticity of TEE transactions stored on the blockchain. 

On Phala 1.0, TEEs were CPU-centric in providing security and privacy. However, most AI models depend upon GPUs for the bulk of their computational requirements. To meet this new and emerging demand, the Phala team decided to upgrade the network to Phala 2.0, which brings in GPU TEE support. This enables higher processing power and efficiency to handle demanding AI workloads. With this upgrade, Phala is also integrating NVIDIA 

 technology, which allows sensitive GPU-based computations to remain isolated and protected, even if the host machine is compromised. 

Another major recent release from Phala Network is 

, a computer solution that empowers developers to offload sensitive workloads into a secure environment. The Dstack SDK streamlines the deployment process, enabling seamless program integration with Phala Network's Confidential Virtual Machine (CVM). It provides developers with an experience comparable to Web 2.0 cloud services such as Amazon Web Services (AWS), but with enhanced security. 

In December 2024, Phala announced a new collaboration with ai16Z to build Eliza’s TEE framework. 

 has emerged as the leading open-source AI agent framework on Solana. Through this partnership, Phala is furthering its role as a privacy-preserving AI framework. By utilizing Phala Network’s TEE, Eliza’s various capabilities will gain cryptographic verifiability and enhanced privacy across different platforms like Telegram, X (formerly Twitter) and Discord. Additionally, Phala’s modularity and custom plug-ins will offer Eliza improved scalability and developer-friendly integrations. 

PHA is the native token of the Phala Network. It serves multiple purposes on the network, such as the following: 

The token was launched through an Initial Parachain Offering. It has a total supply of 1 billion and a 

 (FDV) of $373 million. Initial token distribution was as follows:

The intersection of AI and cryptocurrencies is a new and emerging trend in web3. As with 

 blockchains and DeFi, emerging sectors in the blockchain space often experience intense hype cycles, attracting significant attention and capital. Such growth will eventually demand the development of robust infrastructure to support scalability and innovation. For instance, during the DeFi summer of 2020, projects like 

Similarly, Phala aims to position itself as a foundational infrastructure provider in the AI sector, becoming a key player in the ecosystem through its innovative use of TEE-blockchain hybrid architecture that allows it to provide fast, cheap and secure AI computation.
