Ethereum’s much-anticipated Pectra upgrade has successfully gone live on the Sepolia testnet, marking a key milestone in the path to its mainnet launch. While the deployment was mostly smooth, unexpected technical issues briefly disrupted Sepolia, adding to concerns already raised by Holesky testnet failures last month. With Ethereum’s developers working to stabilize both testnets, the big question now is: Is Pectra ready for the mainnet?

Pectra Goes Live on Sepolia – With a Few Hiccups
The Sepolia deployment of Pectra happened on March 5 at 7:29 AM UTC, and initially, everything looked perfect. Ethereum developer Terence confirmed that the testnet upgrade finalized with a 100% proposal rate, meaning that every validator successfully proposed their assigned blocks.
However, just hours after the launch, problems emerged. Ethereum Foundation developer Tim Beiko revealed that a custom deposit contract issue was causing some Execution Layer (EL) clients to struggle with transaction processing. This led to blocks being proposed without transactions, disrupting normal testnet activity.
Crypto infrastructure expert Emiliano Bonassi also reported that Sepolia was propagating empty blocks, a clear sign of technical instability.
Ethereum Developers Act Quickly
The Ethereum development team didn’t waste time. Within six hours, they identified the issue and rolled out a fix. Validators were instructed to upgrade their nodes, and soon after, Sepolia returned to normal operations.
Beiko confirmed that while the deposit contract issue was unexpected, it was not a fundamental flaw in Pectra itself but rather a testnet-specific problem. Still, the incident highlights the difficulty of rolling out major upgrades – and the potential for surprise issues even after rigorous testing.
Holesky Testnet Issues Could Still Delay Mainnet Launch
While Sepolia’s problems were resolved quickly, Ethereum’s developers still have their hands full with Holesky, another key testnet where Pectra was deployed.
Unlike Sepolia, the Holesky launch on February 24 was far more problematic. Developers ran into validator balance drains, correlation penalties, and chain splits, forcing them to go back to the drawing board.
At this stage, some sources suggest that fixing Holesky’s problems could take at least 18 more days. Since Ethereum’s developers require both Sepolia and Holesky to be stable before setting a mainnet activation date, this means Pectra’s launch could be delayed beyond its original target.
What’s Inside Pectra?
Despite these hurdles, Pectra remains one of Ethereum’s most significant upgrades in years. It introduces 11 Ethereum Improvement Proposals (EIPs) designed to enhance staking, Layer-2 scalability, and wallet functionality.
Some of the most important changes include:
- EIP-7702: Improves account abstraction, making Ethereum wallets function more like smart contracts. This could lead to gasless transactions, automatic payments, and better wallet recovery options.
- EIP-7251: Increases the maximum stake limit for validators from 32 ETH to 2,048 ETH, allowing large staking operations to be more efficient while reducing infrastructure costs.
- EIP-7691: Expands blob storage capacity, which will further improve Layer-2 rollups by making transactions cheaper and faster.
These improvements don’t just benefit Ethereum users – they also strengthen the network’s appeal to institutional investors.
Could Pectra Help Bring Staked Ethereum ETFs?
One of the biggest implications of Pectra is its potential role in staked Ethereum ETFs. Institutional investors have been increasingly interested in staking products, especially after Donald Trump’s 2024 election win, which many believe will bring friendlier crypto regulations. Analysts suggest that Pectra could lay the technical foundation for a regulated staking ETF, making Ethereum more attractive to large investors.
What’s Next?
Ethereum’s developers will meet on March 6 during the All Core Developers (ACD) call to discuss the next steps and decide if the current launch schedule can still be met. With Sepolia back on track but Holesky still facing issues, Pectra is moving closer – but there’s still more work to do.
That said, whenever it does launch, Pectra is set to be a major milestone in Ethereum’s evolution – one that could shape the network for years to come.
