Bots Drive $480B Stablecoin Volume on Ethereum

According to crypto platform CEX.io, 4.84 million stablecoin transfers occurred on Ethereum’s layer-1 network in May, pushing volume to a record $480 billion. The activity was largely automated, signaling a shift in how liquidity and utility are shaping the network.

Lead analyst Illia Otychenko linked the spike to reduced transaction fees in early 2025, reversing a trend of users and liquidity migrating to rival chains and layer-2 solutions. As a result, Ethereum’s mainnet saw an 11% rise in stablecoin market cap this year, while L2 networks saw only a 1% decline.

Stablecoins Shift DeFi Focus Toward Real Utility

Once criticized for MEV manipulation and sandwich attacks, bots are now credited for improving efficiency on Ethereum’s DEXs. In April, stablecoin swaps accounted for 37% of all DEX trades on Ethereum — 32% in May.

The trend reflects a growing focus on real-world payments and stable value transfers. USDC, issued by Circle, became the most traded asset on the network — further signaling Ethereum’s shift toward being a stablecoin infrastructure layer.

Otychenko believes this isn’t a passing trend. “Speculative tokens come and go, but stablecoins stick because they solve real problems,” he said, pointing to the growing need for fast, borderless payments in emerging economies.

Challenges Remain for Ethereum’s Long-Term Lead

Despite its momentum, Ethereum faces key challenges — particularly liquidity fragmentation across layers. Otychenko emphasized that overcoming these hurdles is essential: “This isn’t just a technical issue. It’s what will decide whether Ethereum leads or lags in the next phase of adoption.”

As of May 12, according to data from the analytics platform 8marketcap, Ether surpassed Coca-Cola ($303.5 billion) and Alibaba ($303.7 billion) with a market capitalization exceeding $308 billion, ranking as the 39th-largest asset in the world. During this period, ETH price climbed to approximately $2,550.

The price rally was largely driven by the recently activated Pectra upgrade, which brought notable improvements in layer-2 scaling data storage, validator experience, and smart wallet usability.

Pectra Upgrade Finally Live on Mainnet

Initially scheduled for release in March 2025, the Pectra upgrade was postponed due to technical challenges during the testing phase.

The update was first launched on the Holesky testnet on February 24, but failed to finalize blocks. It was then moved to the Sepolia testnet on March 5, where an attacker mining empty blocks further escalated the issues.

To ensure secure deployment, Ethereum developers launched a new test network called “Hoodi”, and finally, on May 7, the upgrade was successfully rolled out to the mainnet.

With this update, externally owned accounts (EOAs) can now behave like smart contracts, enabling users to pay transaction fees not only with ETH but also with other tokens. Additionally, the staking limit for validators increased from 32 ETH to 2,048 ETH, simplifying operations for larger participants. The number of data blobs per block was also increased, significantly improving layer-2 scalability.

On May 7, ETH was trading around $1,786, and just five days later, it reached $2,550, delivering a 42% return to investors.

Security Experts Warn of New Risks

However, the upgrade also introduced some security vulnerabilities. Experts have warned that new transaction types could allow malicious actors to control EOAs without an on-chain signature from the user.

Some auditors noted that these flaws might let attackers drain funds through off-chain signed messages.

Although Ethereum has made a significant leap in terms of price and market cap, the long-term impact and security concerns following the Pectra upgrade remain under close watch by the crypto community.

According to the Ethereum Foundation, the update will be deployed on the Holesky testnet on February 24, 2025, followed by the Sepolia testnet on March 5, 2025. Finally, the upgrade will go live on the Ethereum mainnet on April 8, 2025.

With this upgrade, the Ethereum network is expected to become faster, more secure, and more user-friendly. It will bring major advancements in account management, transaction speed, and security, making it a key step in Ethereum 2.0’s evolution.

What’s New in the Pectra Upgrade?

Significant improvements will be made in Account Abstraction, simplifying private key management for users. Smart contracts will function directly as wallets, allowing for more secure and efficient transactions. This enhancement will enable a smoother and more seamless experience for Ethereum users.

From a scalability perspective, the Ethereum network will be able to process more transactions efficiently. Transaction fees will be reduced, and confirmation times will be accelerated. These optimizations will make Ethereum more suitable for broader adoption and high-volume applications.

Security and user experience will also see notable enhancements. Advanced authentication mechanisms will be implemented, making decentralized applications (dApps) more accessible. With these improvements, Ethereum users will experience a safer and more seamless network environment.

The Pectra upgrade is a significant step toward achieving Ethereum’s long-term goals. By improving efficiency, scalability, and user-friendliness, it will contribute greatly to the Ethereum 2.0 roadmap, marking a major innovation in the crypto space.
