How Ethereum Pectra Upgrade Affects Mitosis Development

The Ethereum upgrade called Pectra Upgrade, scheduled for the second half of 2025, promises to be one of the most significant steps in the development of the Ethereum network since The Merge and the subsequent implementation of EIP-4844 (proto-danksharding). This upgrade is aimed at optimizing scalability, improving UX and increasing security, and its impact will be felt across the entire stack of the Ethereum ecosystem - especially for infrastructure projects like Mitosis.

What is Mitosis?

Mitosis is an interchain interoperability protocol focused on simple, fast and cheap asset transfers between L2 solutions. Unlike classic bridges, Mitosis relies on a modular architecture and deep integration with the rollup-oriented world. It uses a minimalist design, its own contract cores and off-chain infrastructure to achieve high performance and reliability when transferring liquidity between networks like Arbitrum, Optimism, Base and others.

Mitosis Before vs. After Pectra Upgrade

What will the Pectra Upgrade bring?

The Pectra update includes several key components at once:

EIP-3074 (AUTH and AUTHCALL) — new opcodes that allow abstracting signatures and expanding the capabilities of regular EOAs (externally owned accounts). This is important for UX and key management.

1.       EIP-7251 ("Max Epoch Churn Limit") — improvements in validator and Beacon Chain scaling.

2.       EIP-6110 — simplifies the processing of validator data in blocks.

3.       Transition to full danksharding in the coming phases (Pectra is preparing for it).

All these changes directly or indirectly affect modular and multi-chain systems, especially if they actively use L2 and rollup infrastructure — like Mitosis.

How Pectra Upgrade Will Impact Mitosis Development

1. Improved UX for Bridge Users

With EIP-3074, Mitosis will be able to offer a more flexible model for interaction between wallets and smart contracts. It will be possible to create meta-transactions and operations on behalf of the user without the need to directly interact with contracts - this means that Mitosis bridge interfaces can become a one-click experience, without even a separate approve or deposit call.

This will increase adoption among non-crypto-native users, especially on mobile devices, and will make Mitosis one of the most seamless solutions in the ecosystem.

2. Deeper integration with danksharding and blob data

While full implementation of danksharding is expected after Pectra, preparatory changes (started with EIP-4844 and developed further) will allow Mitosis to process and store temporary blob data more efficiently. This reduces the load on the main chain and opens the way to off-chain proofs or blob-based messaging, which is critical for the reliability of cross-chain communication.

3. Expanding the capabilities of the zk infrastructure

Many rollup solutions that Mitosis runs on already use zk proofs (e.g. zkSync, Scroll). Improvements in Pectra and the associated steps towards scaling make zk networks cheaper and faster, which reduces the cost of operations inside Mitosis. This will allow Mitosis to expand its reach to L2 networks without losing efficiency, and even go beyond Ethereum networks while maintaining support for the rollup architecture.

4. New governance and authorization models

With the advent of AUTHCALL and other tools in EIP-3074, Mitosis will be able to implement smart multisig schemes, role abstraction, and custom security models at the user and operator level. This is important in light of the growing volume of TVL in the protocol and the need for more robust cross-chain liquidity management.

5. Lower Gas and Cross-Chain Costs

Many of Pectra’s upgrades are aimed at optimizing gas consumption and increasing throughput. For Mitosis, where every transaction involves cross-chain communication and confirmation, this is critical. Cheaper transactions mean that bridges become economically viable even for small amounts, opening up the market for micropayments and GameFi solutions.

Key Pectra Features and Their Impact on Mitosis

Conclusion

The Ethereum upgrade called Pectra is not just an internal upgrade of the network, but a strong signal to the entire ecosystem of modular and cross-chain protocols. For Mitosis, as a next-generation infrastructure layer, this is a chance to strengthen its position and become a leader in L2 communication solutions. The synergy between UX improvements, danksharding scalability, and authorization capabilities makes Pectra an acceleration point for the entire Mitosis architecture.

The future of multi-chain communication is not built on isolated bridges, but on deeply integrated, modular, and scalable solutions. And Mitosis will feel right at home in this new world.
