In DeFi transactions, regular users often find themselves at a disadvantage due to delays and front-running. AutoFi leverages built-in automation and native oracles to achieve instant execution within the same block, eliminating delays, front-running, and missed opportunities. It not only enhances transaction quality but also breaks down the barrier to fair trading, allowing every user to enjoy an institutional-grade trading experience and truly level the playing field in the DeFi ecosystem.

AutoFi Era: Supra Zero-Block Delay Automation Making DeFi Transactions Fairer

In DeFi transactions, the ideal execution price you envision and the final price you end up with often have discrepancies. This is not merely a matter of luck but rather a structural flaw inherent in the DeFi ecosystem—a market environment that is not very user-friendly. While the vision of decentralized finance is to create a more equitable and transparent trading system, the reality is that regular users often struggle to obtain comparable execution quality and trading opportunities when facing professional traders.

AutoFi brings about a revolutionary change. Building on Supra's built-in automation and native oracles, AutoFi injects powerful automation capabilities into DeFi transactions. It not only optimizes trading fairness but fundamentally changes the way transactions are conducted—when your trade conditions are met, the transaction is executed instantly within the same block.

No delays, no front-running, no missed opportunities.

This innovation not only significantly improves transaction execution quality but also completely shatters the barrier to fair trading, allowing regular users to enjoy an institutional-level trading experience and truly stand on an equal footing with professional players in the DeFi race track.

Current Transaction Discrepancies

If you have ever traded on a decentralized exchange (DEX), you must have experienced the following dilemmas:

· You identified a trading opportunity, but the execution speed was not fast enough, causing you to miss out on a great opportunity.

· Your transaction remained pending for a long time after submission, while the market rapidly changed, working against you.

· Your trade was "sandwiched" by larger players, leading to additional slippage and losses.

· Your stop-loss order triggered too late, resulting in losses far beyond your expectations.

These issues are not just inconveniences but rather fundamental unfairness in the existing DeFi system. Institutions and tech-savvy traders leverage trading bots, private connections, and advanced infrastructure to execute trades at lightning speed, seizing the market's advantage. Meanwhile, regular users can only manually operate, click buttons, and passively wait, with no advantage in a competitive market, merely hoping that the trade will go as planned.

This is exactly the situation AutoFi is trying to change.

AutoFi's Core Breakthrough: Same-Block Execution

AutoFi's core advantage lies in zero-block-delay automation—a revolutionary way of executing transactions that completely eliminates the time gap between transaction condition satisfaction and actual execution.

The traditional blockchain automation execution process is as follows:

· Block N: Trigger transaction condition (e.g., ETH price drops below $3,000).

· External automation network detects this condition and submits the transaction.

· Transaction enters the mempool (memory pool) awaiting confirmation.

· Block N+1 (or later): Transaction finally executes.

However, in AutoFi's Zero-Block-Delay mechanism, the entire process is fundamentally altered:

· Block N: Transaction condition triggers (ETH price drops below $3,000).

· Block N: Transaction is executed immediately within the same block.

This is not just an improvement in execution speed but a breakthrough at the architectural level, compressing the time delay between transaction intent and actual execution to the physical limit. Your transaction conditions and execution no longer span multiple blocks but are completed within the same atomic block time unit.

What Does This Mean for On-Chain Transaction Experience?

1. Trade According to Your Rules, Not Market Conditions

In traditional trading, from identifying an opportunity to final transaction confirmation, the entire process is influenced by market fluctuations. However, with the AutoFi mechanism, you can set precise transaction conditions and automatically execute them the moment the conditions are met—no delays, no slippage.

For example, you can set the following trade rule:

"When BTC exceeds $80,000 and XRP is below $2.00, use my stablecoin to buy 1 ETH."

When both conditions are met simultaneously within a block, the trade executes instantly. You don't need to monitor the market constantly or manually seize trading opportunities; everything is done automatically and efficiently on-chain.

2. Easily Implement Complex Trading Strategies

Professional traders often use highly complex conditional trading strategies, and in traditional DeFi, ordinary users can hardly implement these strategies. AutoFi has thoroughly changed this situation, enabling multi-condition trading strategies to have machine-level precision and automatic execution:

“Automatically rebalance when Asset A exceeds 30% of the portfolio value.”

“Buy Asset X, but only execute when its 4-hour volatility is below 5%.”

“If the Bitcoin market share falls below 45%, automatically convert half of my stablecoins to ETH.”

These are no longer just theoretically possible but actionable strategies that do not require writing code, running trading bots, or setting up complex infrastructure.

3. Prevent Malicious Trading Behavior

In the current DeFi ecosystem, technical traders can front-run your pending transactions and exploit flashbots (MEV) or “sandwich attacks” to profit, causing you additional losses.

AutoFi completely eliminates this risk through in-block execution and randomized transaction sequencing.

When your transaction and triggering conditions execute in the same block, others have no opportunity to front-run your transaction for profit. Your transaction will execute exactly as you have set it up, without external manipulation or exploitation by arbitrageurs.

4. Never Miss a Trading Opportunity Again

How many times have you found a perfect trading opportunity but missed it because you were not in front of your computer? Or during intense market volatility, you were asleep and unable to act?

AutoFi converts your trading intent into a 24/7 full-time execution agent—it does not rest, miss opportunities, or get affected by emotions. Your trading strategy remains active, automatically executing when market conditions meet the set requirements—whether you are at work, in a meeting, or sound asleep.

Real Scenario: How AutoFi Works

Let's explore how AutoFi provides significant advantages to ordinary users in actual trading scenarios, surpassing traditional DeFi or manual trading methods.

Scenario 1: Perfect Entry Timing

Traditional DeFi: You anticipate ETH to bounce back after dropping to $2,000, so you set price alerts and keep a close watch. When ETH finally reaches the target price, you rush to place an order, but by the time the trade confirmation is completed, the price has surged back to $3,100, missing the optimal entry opportunity.

Using AutoFi: You set up an automation strategy in advance: "When the ETH price hits $2,000, automatically buy 1 ETH." Without the need to constantly monitor the market, the ETH transaction is executed automatically within the same block when the price hits $2,000, ensuring execution at the desired price and no longer missing out on opportunities.

Scenario 2: Portfolio Protection

Traditional DeFi: In a sudden market volatility, you receive a notification and try to adjust your position, but by then the price has moved significantly. Your stop-loss order triggers too late, resulting in losses far beyond your expectations.

Using AutoFi: You set up an automated protection mechanism in advance: "If ETH drops by over 5% within 1 hour, automatically convert 25% of the holdings to a stablecoin." When the market fluctuation triggers this condition, the transaction is immediately executed within the same block, hedging the risk before further price drops, avoiding greater losses.

Scenario 3: Cross-Asset Arbitrage Opportunity

Traditional DeFi: When you notice a rapid increase in Bitcoin, certain altcoins typically follow suit, providing an arbitrage opportunity. However, due to swift market changes, manual operations struggle to precisely time the optimal entry point, potentially missing out on profit margins.

Using AutoFi: You set up an automated arbitrage strategy in advance: "When BTC rises by 3% within 30 minutes, automatically buy $1,000 of Token X." This strategy will automatically execute within the same block once the conditions are met, capturing arbitrage opportunities at machine-level speed, without manual intervention, achieving more precise trade executions.

Beyond Trading: A Grand Vision

While the advantages of AutoFi in trade execution are evident, its impact extends far beyond this, as it is reshaping the core mechanics of DeFi:

Self-Protecting Collateral

Traditional lending protocols rely on overcollateralization to cope with market fluctuations, whereas AutoFi empowers collateral assets with self-adjusting capabilities—when the market changes, the system can automatically replenish funds or adjust positions, proactively avoiding liquidation risks before they occur, ensuring fund security.

A Fresh Upgrade in Capital Efficiency

In the traditional lending model, users need to reserve a significant amount of idle funds as a safety buffer, reducing capital efficiency. AutoFi, through intelligent fund scheduling, unlocks liquidity when truly needed, automatically retracting when idle, maximizing fund efficiency without increasing risk.

Composable DeFi Strategy

AutoFi enables cross-protocol automated execution, allowing funds to flow freely between borrowing markets, DEXes, and yield farms based on predefined conditions. This dynamic strategy framework breaks through the existing limitations of DeFi, making previously challenging automated trading strategies a reality.

The Future of Trading: Fully Automated

AutoFi not only enhances transaction execution speed but fundamentally reshapes the trading paradigm of DeFi. It completely eliminates the time gap between "condition triggering" and "transaction execution," creating a brand new on-chain trading experience:

Fairness: All users can enjoy the same execution quality, no longer restricted by technological advantages.

Efficiency: Funds are deployed precisely, transactions are automatically executed at the optimal time, avoiding missing out on market opportunities.

Autonomy: Trading strategies require no manual intervention, triggering automatically once conditions are set, without the need to monitor the market at all times.

Security: Eliminating front-running and unfair competition, ensuring transactions are executed according to predefined conditions without external manipulation.

The era of manual trading, missing out on opportunities, and being at an execution disadvantage is coming to an end. AutoFi enables trading strategies to execute at machine-level speed, providing equally efficient trading experiences for both professional traders and DeFi newcomers.

The future of trading is no longer about competing in click speed but achieving precise execution through intelligent automation. AutoFi is leading this transformation, and it is within reach.

$COIN Joins S&P 500, but Coinbase Isn't Celebrating

On May 13, S&P Dow Jones Indices announced that Coinbase would officially replace Discover Financial Services in the S&P 500 on May 19. While other companies like Block and MicroStrategy, closely tied to Bitcoin, were already part of the S&P 500, Coinbase became the first cryptocurrency exchange whose primary business is in the index. This also signifies that cryptocurrency is gradually moving from the fringes to the mainstream in the U.S.



On the day of the announcement, Coinbase's stock price surged by 23%, surpassing the $250 mark. However, just 3 days later, Coinbase was hit by two consecutive events: a hack where employees were bribed to steal customer data and a demand for a $20 million ransom, and an investigation by the U.S. Securities and Exchange Commission (SEC) into the authenticity of its claim of having over 100 million "verified users" in its securities filings and marketing materials. These two events acted as mini-bombs, and at the time of writing, Coinbase's stock had already dropped by over 7.3%.


Coincidentally, Discover Financial Services, being replaced by Coinbase, can also be considered the "Coinbase" of the previous payment era. Discover is a U.S.-based digital banking and payment services company headquartered in Illinois, founded in 1960. Its payment network, Discover Network, is the fourth largest payment network apart from Visa, Mastercard, and American Express.


In April, after the approval of the acquisition of Discover by the sixth-largest U.S. bank, Capital One, this well-established digital banking company of over 60 years smoothly handed over its S&P 500 "seat" to this emerging cryptocurrency "bank." This unexpected coincidence also portrayed the handover between the new and old eras in Coinbase's entry into the S&P 500, resembling a relay race scene. However, this relay baton also brought Coinbase's accumulated "external troubles and internal strife" to a tipping point.


Side Effects of ETFs


Over the past decade, cryptocurrency exchanges have been the most stable "profit machines." They play a role in providing liquidity to the entire industry and rely on trading fees to sustain their operations. However, with the comprehensive rollout of ETF products in the U.S. market, this profit model is facing unprecedented challenges. As the leader in the "American stack," with over 80% of its business coming from the U.S., Coinbase is most affected by this.



Starting from the approval of Bitcoin and Ethereum spot ETFs, traditional financial capital has significantly onboarded users and funds that originally belonged to exchanges in a more cost-effective, compliant, and transparent manner. The transaction fee revenue of cryptocurrency exchanges has started to decline, and this trend may further intensify in the coming months.


According to Coinbase's 2024 Q4 financial report, the platform's total trading revenue was $417 million, a 45% year-on-year decrease. The contribution of BTC and ETH's trading revenue dropped from 65% in the same period last year to less than 50%.


This decline is not a result of a decrease in market enthusiasm. In fact, since the approval of the Bitcoin ETF in January 2024, the inflow of BTC into the U.S. market has continued to reach new highs, with asset management giants like BlackRock and Fidelity rapidly expanding their management scale. Data shows that BlackRock's iShares Bitcoin ETF (IBIT) alone has surpassed $17 billion in assets under management. As of mid-May 2025, the cumulative net inflow of 11 major institutional Bitcoin spot ETFs on the market has exceeded $41.5 billion, with a total net asset value of $1214.69 billion, accounting for approximately 5.91% of the total Bitcoin market capitalization.

Institutional investors and some retail investors are shifting towards ETF products, partly due to compliance and tax considerations. On one hand, ETFs have much lower trading costs compared to cryptocurrency exchanges. While Coinbase's spot trading fee rate varies annually in a tiered manner but averages around 1.49%, for example, the management fee for IBIT ETF is only 0.25%, and the majority of ETF institution fees fluctuate around 0.15% to 0.25%.



In other words, the more rational users are, the more likely they are to move from exchanges to ETF products, especially for investors aiming for long-term holdings.


According to multiple sources, several institutions, including VanEck and Grayscale, have submitted applications to the SEC for a Solana (SOL) ETF, with some institutions also planning to submit an XRP ETF proposal. Once approved, this may trigger a new round of fund migration. According to a report submitted by Coinbase to the SEC, as of April, the platform's trading revenue from XRP and Solana accounted for 18% and 10%, nearly one-third of the platform's fee revenue.



However, the Bitcoin and Ethereum ETFs passed in 2024 also reduced the fees for these two tokens on Coinbase from 30% and 15% to 26% and 10%, respectively. If the SOL and XRP ETFs are approved, it will further undermine the core fee revenue of exchanges like Coinbase.


The expansion of ETF products is gradually weakening the financial intermediary status of cryptocurrency exchanges. From their original roles as matchmakers and clearers to now gradually becoming mere "on-ramps and off-ramps" for funds, exchanges are seeing their marginal value squeezed by ETFs.


Robinhood Takes a Stand, Traditional Brokerages Join the Fray


On May 12, 2025, SEC Chairman Paul S. Atkins gave a keynote speech at the Tokenization and Cryptocurrency Working Group roundtable. The theme of his speech revolved around "It is a new day at the SEC," where he indicated that the SEC would not approach enforcement and regulation the same way as before but would instead pave the way for cryptocurrency assets in the U.S. market.



With signs of cryptocurrency compliance such as the SEC's "NEW DAY" declaration, an increasing number of traditional brokerages are attempting to enter the cryptocurrency industry. One of the most representative cases is the well-known U.S. brokerage Robinhood, which began expanding its crypto business in 2018. By the time of its IPO in 2021, Robinhood's crypto business revenue accounted for over 50% of the company, with a significant boost from the Dogecoin "moonshot" promoted by Musk.


In Q1 2025 earnings report, Robinhood showcased strong growth, especially in revenue from cryptocurrency and options trading. Fueled by Trump's Memecoin, cryptocurrency-related revenue reached $250 million, nearly doubling year-over-year. Consequently, Robinhood Gold subscription users reached 3.5 million, a 90% increase from the previous year, with the rapid growth of Robinhood Gold providing the company with a stable source of income.



Meanwhile, RobinHood is actively pursuing acquisitions in the cryptocurrency space. In 2024, it announced a $2 billion acquisition of the long-standing European cryptocurrency exchange Bitstamp. Additionally, Canada's largest cryptocurrency CEX, WonderFi, which recently went public on the Toronto Stock Exchange, also announced its integration with RobinHood Crypto. After obtaining virtual asset licenses in the UK, Canada, Singapore, and other markets, RobinHood has taken a proactive approach in the compliant cryptocurrency trading market.



Furthermore, an increasing number of brokerage firms are exploring the same path. Futu Securities, Tiger Brokers, and others are also dipping their toes into cryptocurrency trading, with some having applied for or obtained the VA license from the Hong Kong SFC. Although their user bases are currently small, traditional brokerages have a natural advantage in user trust, regulatory licenses, and low fee structures. This could pose a threat to native cryptocurrency platforms in the future.



User Data Breach: Is Coinbase Still Secure?


In April 2025, security researchers discovered that some Coinbase user data was leaked on the dark web. While the platform initially responded by attributing it to a "technical misinformation," it still raised concerns among users regarding its security and privacy protection. Just two days before Dow Jones Indexes announced Coinbase's addition to the S&P 500 Index, on May 11, 2025, Coinbase received an email from an unknown threat actor claiming to have obtained customer account information and internal documents, demanding a $20 million ransom to keep the data private. Subsequent investigations confirmed the data breach.


Cybercriminals obtained the data by bribing overseas customer service agents and support staff, mainly in "non-U.S. regions such as India." These agents abused their access to Coinbase's internal customer support system and stole customer data. As early as February this year, blockchain detective ZachXBT revealed on X platform that between December 2024 and January 2025, Coinbase users lost over $65 million to social engineering scams, with the actual amount potentially higher.


Among the victims was a well-known figure, 67-year-old Ed Suman, an established artist in the art world for nearly two decades, having been involved in the creation of artworks such as Jeff Koons' "Balloon Dog" sculpture. Earlier this year, he fell victim to an impersonation scam involving fake Coinbase customer support, resulting in a loss of over $2 million in cryptocurrency. ZachXBT critiqued Coinbase for its inadequate handling of such scams, noting that other major exchanges have not faced similar issues and recommending Coinbase to enhance its security measures.


Amidst a series of ongoing social engineering incidents, although there has not been any impact on user assets at the technical level so far, it has raised concerns among many retail and institutional investors. Especially institutions holding massive assets on Coinbase. Just considering the U.S. BTC ETF institutions, as of mid-May 2025, they collectively hold nearly 840,000 BTC, and 75% of these are custodied by Coinbase. If we price BTC at $100,000, this amount reaches a staggering $63 billion, which is equivalent to the nominal GDP of two Iceland in the year 2024.

In addition, Coinbase Custody also serves over 300 institutional clients, including hedge funds, family offices, pension funds, and endowments. As of the Q1 2025 financial report, Coinbase's total assets under management (including institutional and retail clients) reached $404 billion. The specific amount of institutional custodied assets was not explicitly disclosed in the latest report, but it should still be over 50% based on the Q4 2024 report.

Once this security barrier is breached, not only could the rate of user attrition far exceed expectations, but more importantly, institutional trust in it would undermine the foundation of its business. Therefore, after a hacking event, Coinbase's stock price plummeted significantly.


CEXs are All in Self-Rescue Mode


Facing a decline in spot trading fee revenue, Coinbase is also accelerating its transformation, attempting to find growth opportunities in derivatives and emerging assets. Coinbase acquired a stake in the options platform Deribit at the end of 2024 and announced the official launch of perpetual contract products in 2025. This acquisition fills in Coinbase's gap in options trading and its relatively small global market share.



Deribit has a strong presence in non-U.S. markets, especially in Asia and Europe. The acquisition has enabled Coinbase to gain a dominant position in bitcoin and ethereum options trading on Deribit, accounting for approximately 80% of the global options trading volume, with daily trading volume remaining above $2 billion.


Meanwhile, 80-90% of Deribit's customer base consists of institutional investors, with their professionalism and liquidity in the Bitcoin and Ethereum options market highly favored by institutions. Coinbase's compliance advantage, coupled with its already robust institutional ecosystem, makes it even more suitable. By using institutions as an entry point, it can face the squeeze from giants like Binance and OKX in the derivatives market.



Facing a similar dilemma is Kraken, which is attempting to replicate Binance Futures' model in non-U.S. markets. Since the derivatives market relies more on professional users, fee rates are relatively higher and stickiness is stronger, making it a significant source of revenue for exchanges. In the first half of 2025, Kraken completed the acquisition of TradeStation Crypto and a futures exchange, aiming to build a complete derivatives trading ecosystem to hedge the risk of declining spot transaction fee income.


With the surge of Memecoin in 2024, Binance, OKX, and various CEX platforms began massively listing small-market-cap, highly volatile tokens to activate active trading users. Due to the wealth effect and trading activity of Memecoins, Coinbase was also forced to join the battle, successively listing popular tokens from the Solana ecosystem such as BOOK OF MEME and Dogwifhat. Although these coins are controversial, they are frequently traded, with fee rates several times higher than mainstream coins, serving as a "blood-boosting" method for spot trading.


However, due to its status as a publicly traded company, this practice is a riskier endeavor for Coinbase. Even in the current crypto-friendly environment, the SEC is still investigating whether tokens like SOL, ADA, and SAND constitute securities.


In addition to the forced transformation strategies carried out by the aforementioned CEXs, they are also starting to lay out RWAs and the most talked-about stablecoin payment fields, such as the PYUSD launched through a collaboration between Coinbase and Paypal, Coinbase's support for the Euro stablecoin EURC by Circle that complies with EU MiCA regulatory requirements, or the USD1 launched through a collaboration between Binance and WIFL. In the increasingly crowded trading field, many CEXs have shifted their focus from just the trading market to the application field.


The golden age of transaction fees has quietly ended, and the second half of the crypto exchange platform game has silently begun.
