The 1inch Network has proactively optimized its smart contracts in preparation for the Ethereum Berlin hard fork, ensuring users benefit from reduced transaction costs despite broader network changes that could increase gas fees across DeFi platforms. Set to activate at block 12,244,000 on April 15, the Berlin upgrade introduces significant adjustments to gas pricing — changes designed to enhance Ethereum’s long-term security and efficiency.
While many decentralized finance (DeFi) protocols may see a 2–3x increase in gas costs during token swaps, 1inch stands out by delivering improved cost efficiency post-fork. This achievement underscores the platform’s commitment to user-centric innovation and technical excellence in an evolving blockchain landscape.
Understanding the Ethereum Berlin Hard Fork
The Berlin hard fork is a major non-backward-compatible upgrade to the Ethereum network, part of a broader roadmap leading toward Ethereum 2.0. It implements four Ethereum Improvement Proposals (EIPs), with EIP-2929 being the most impactful for gas mechanics.

EIP-2929 adjusts the gas costs associated with certain state-access operations to deter potential Denial-of-Service (DDoS) attacks. Specifically:
- The first read from a smart contract’s storage now costs 2,100 gas, up from 800.
- The first inter-contract call now costs 2,600 gas, up from 700.
- However, repeated operations within the same transaction are heavily discounted to just 100 gas each.
This change rewards efficient, batched transactions — a design principle already central to 1inch’s architecture.
Why Most DeFi Platforms Will See Higher Gas Fees
For most decentralized exchanges (DEXs) and DeFi protocols, these gas repricings mean higher operational costs. Since many platforms execute multiple independent state accesses without optimizing call sequences, they’ll face inflated fees after the fork.
Users conducting simple token swaps might experience noticeably higher expenses — especially on platforms that haven't updated their smart contracts to align with the new gas model.
However, this shift also creates a competitive advantage for protocols built with gas efficiency in mind. And few are better positioned than 1inch, which anticipated these changes months in advance.
How 1inch Outperforms Post-Berlin
Recognizing the implications of EIP-2929 early, the 1inch Labs team began optimizing their smart contracts in December 2020 — well ahead of the April 2025 activation date. Their strategy focused on restructuring transaction flows to maximize use of low-cost repeated operations.
By batching storage reads and contract calls within single transactions, 1inch minimizes expensive "first access" operations. As a result:
- Transaction costs through the 1inch aggregator will be lower after the Berlin fork than before.
- Compared to other Ethereum-based DeFi protocols, 1inch offers some of the lowest gas expenditures for swaps and liquidity provision.
This optimization ensures that even as network-wide gas prices rise, 1inch users continue to enjoy cost-effective trading experiences.

FAQ: Your Questions About the Berlin Fork & 1inch Optimization
Q: What is the Ethereum Berlin hard fork?
A: It’s a network upgrade activating on April 15 that modifies gas costs and improves Ethereum’s resistance to DDoS attacks. It includes EIPs like 2929, 2718, 2930, and 2932.
Q: Will I pay more gas when swapping tokens after Berlin?
A: Most users on standard DEX platforms likely will — up to 2–3 times more. But if you use 1inch, optimized smart contracts mean lower or comparable fees even after the change.
Q: Why does EIP-2929 increase some gas costs?
A: To prevent spam attacks by making repeated state access expensive unless bundled efficiently within one transaction. It strengthens network security.
Q: How did 1inch make transactions cheaper despite higher base gas?
A: By redesigning their contract logic to reuse storage reads and calls within a single transaction, taking full advantage of the reduced 100-gas cost for repeated operations.
Q: Is the Berlin hard fork risky for users?
A: No — it’s a planned upgrade supported by major clients and infrastructure providers. There’s no chain split expected, and platforms like 1inch ensure smooth transitions.

The Bigger Picture: Efficiency as a Competitive Edge
The Berlin hard fork highlights a growing trend in Ethereum development: efficiency is now a core competitive metric. As Layer 1 costs remain volatile, protocols that optimize at the smart contract level gain real advantages in user retention and volume growth.
1inch’s proactive approach demonstrates foresight and technical agility. While others react, 1inch innovates — turning what could have been a cost burden into an opportunity for greater savings.
This mindset extends beyond Berlin. Future upgrades like London and the transition to Proof-of-Stake will bring further challenges and opportunities. Platforms investing in optimization today are building resilience for tomorrow’s Ethereum ecosystem.
Final Thoughts: Why This Matters for DeFi Users
For everyday users, blockchain upgrades can seem abstract. But the real impact lies in wallet balances — specifically, how much ETH you spend per transaction.
With the Berlin hard fork, many DeFi users face higher costs. But those using optimized protocols like 1inch won’t just avoid the hike — they’ll come out ahead.
