The Ethereum network continues its relentless journey toward scalability, security, and user-centric design. The upcoming Prague-Electra upgrade—expected on the Sepolia testnet around March 5, 2025, and mainnet by April 8—marks one of the most significant transformations since The Merge. This hard fork integrates 11 critical EIPs that collectively reshape how users interact with Ethereum, how developers build on it, and how Layer 2 solutions scale within its ecosystem.
While not as headline-grabbing as previous milestones like London or Merge, the Prague upgrade is a pivotal step in Ethereum’s long-term vision: enabling mass adoption through account abstraction, enhanced data availability, and optimized staking mechanics.
What's New in the Prague-Electra Upgrade?
At its core, this upgrade reflects Ethereum’s evolving priorities—moving from pure protocol stability to user experience, developer flexibility, and ecosystem-wide efficiency. Let’s break down the key components shaping this transformation.
EIP-7702: Introducing Account Abstraction at the Protocol Level
EIP-7702 is arguably the most transformative change in this release. It introduces account abstraction (AA) natively into Ethereum’s execution layer, allowing externally owned accounts (EOAs) to temporarily behave like smart contract accounts (SCAs) when needed.

This means:
- Users no longer need to pre-deploy a smart wallet to access advanced features.
- Transactions like batch operations, gasless swaps, or session keys become seamless.
- DApps can initiate transactions on behalf of users without requiring full wallet migration.
For platforms like exchanges, DAOs, or DeFi protocols, this reduces operational costs significantly—potentially cutting transaction overhead by over 50%. However, it also increases complexity in permission management. If wallets fail to implement proper safeguards, attackers could exploit misconfigured sessions or signature logic.
While EIP-3074 laid early groundwork for sender delegation, EIP-7702 brings full AA functionality closer to mainstream usability—without forcing every user to adopt complex wallet infrastructure upfront.
Enhancing Security and Interoperability
EIP-2537: BLS12-381 Precompiles for Advanced Cryptography
Security and privacy are getting a major boost via EIP-2537, which adds precompiled contracts for BLS12-381 elliptic curve operations. This enables efficient verification of BLS signatures—a cornerstone of Ethereum 2.0’s consensus layer.
Key benefits include:
- Lower gas costs for multi-signature and threshold signature schemes.
- Native support for zero-knowledge proofs (zk-SNARKs) and homomorphic encryption.
- Improved interoperability with privacy-focused chains like Zcash.
Developers building privacy-preserving applications or cross-chain bridges will find this particularly valuable. The performance gains make cryptographic primitives more accessible, paving the way for next-gen identity and authentication layers.
EIP-2935: Storing Historical Block Hashes On-Chain
To support future stateless clients and Verkle tree adoption, EIP-2935 stores the last 8,192 block hashes directly in a system contract. This allows light clients to verify historical data without storing the entire chain.
Use cases include:
- Rollups verifying L1 state roots efficiently.
- Oracle networks validating off-chain data against past blocks.
- Fraud-proof systems in optimistic rollups requiring quick access to old headers.
Though invisible to end users, this change strengthens Ethereum’s foundation for scalable verification—a prerequisite for achieving "The Surge" vision of one million TPS.
Optimizing Ethereum Staking Infrastructure
With over 830,000 validators active as of late 2023, Ethereum’s staking ecosystem demands better efficiency and flexibility. Several EIPs target these needs head-on.
EIP-6110: On-Chain Deposit Processing
Currently, validator deposits rely on a cross-layer voting mechanism (eth1data), creating latency and potential failure points. EIP-6110 moves deposit processing entirely on-chain, embedding them directly into execution layer blocks.
Benefits:
- Faster deposit finality.
- Reduced reliance on external consensus mechanisms.
- Enhanced security for staking pools like Lido or Rocket Pool.
EIP-7002: Execution Layer Triggerable Withdrawals
Now, validators using withdrawal credentials starting with 0x01 can trigger exits and partial withdrawals directly from the execution layer—no need to wait for consensus layer triggers.
This gives stakers more control over their funds and enables automated compounding strategies within DeFi protocols.
EIP-7251: Increasing Max Effective Balance to 2,048 ETH
Large stakers currently face inefficiencies because each validator is capped at 32 ETH. To manage larger stakes, they must run multiple validators—an operational burden.
EIP-7251 raises the cap to 2,048 ETH per validator, reducing overhead for institutional stakers. However, critics warn this may accelerate centralization risks if a few large entities dominate validation.
Still, the minimum remains at 32 ETH—ensuring small stakers aren’t priced out while allowing economies of scale for larger operators.
EIP-7549: Moving Committee Index Outside Attestations
A technical but impactful change: moving the committee index out of attestation signatures reduces verification complexity. Since identical votes now produce identical signing roots, clients can batch-validate signatures more efficiently—especially in zk circuits.
This improves client performance and supports future upgrades like single-slot finality.
Empowering the Layer 2 Ecosystem
Ethereum’s scalability hinges on L2 growth. The Prague upgrade reinforces this strategy with three key proposals.
EIP-7623: Increasing Calldata Costs
To discourage inefficient use of blockchain space, calldata gas fees rise from 4/16 gas per byte to 10/40 gas (for zero/non-zero bytes). This incentivizes rollups to shift state publishing from calldata to blobs—cheaper, ephemeral storage introduced in Cancun.

EIP-7691: Doubling Blob Capacity
Blob capacity per block increases from a target of 3 (max 6) to 6 (max 9). This doubles available data bandwidth for rollups like Arbitrum, Optimism, and Polygon zkEVM.
More blobs = lower L2 transaction fees = higher throughput.
EIP-7840: Dynamic Blob Configuration
Adds a new configuration parameter allowing dynamic adjustment of blob limits and pricing sensitivity (baseFeeUpdateFraction). This future-proofs Ethereum against fluctuating L2 demand.
Together, these changes signal Ethereum’s commitment to being a data availability engine—not just a settlement layer.
Is This Innovation—or Just Catching Up?
Despite the breadth of improvements, some argue Ethereum is reacting rather than leading. Features like account abstraction and BLS cryptography have already seen real-world testing on alternative L1s like Aptos or Solana.
Yet Ethereum’s strength lies in ecosystem coordination. Wallets like MetaMask, Trust Wallet, Safe, and Uniswap are already preparing for EIP-7702 compatibility. The sheer scale of developer alignment gives these upgrades unmatched traction.
Moreover, unlike fragmented ecosystems, Ethereum can push network-wide standards—ensuring interoperability across thousands of projects.
