Remember when Ethereum gas fees felt like paying rent? In 2025, it’s a whole different story. L2s are dirt cheap now. Ethereum L2 solutions like Base, Optimism, Arbitrum and zkSync haven’t just caught up. They’ve surpassed many L1s in cost efficiency. On chain activity on these L2s usually costs just a few cents, sometimes even fractions of a cent, thanks to Ethereum rollup upgrades. They’re now cheaper than Solana, Fantom, Avalanche and several other big name L1s. A massive shift from just a few years ago, when Ethereum gas fees were memed to death during NFT and DeFi peaks. This is all thanks to rollup tech bundling transactions and posting them to mainnet, reducing fees dramatically. EIP-4844 (blobspace) made data availability more scalable, and a combo of user growth and dev support has turned L2s into full ecosystems of their own. Meanwhile, many alt L1s are stuck dealing with demand spikes, centralization concerns or just low usage. Ethereum, on the other hand, has modularized like a pro. So next time someone says “ETH is expensive,” show them the receipts. The future isn’t just Ethereum. It’s Ethereum L2s.
