Clear now: Base won.

• @base alone accounts for $113.11M in "finance" gas fees on @growthepie_eth.
• @arbitrum sits at $48.18M.
• @zksync Era at $38.13M.

Then the drop-off starts:

• @Optimism $25.75M
• @LineaBuild $18.93M
• @Scroll_ZKP $17.51M

Put differently:
Base ≈ 42% of all L2 Finance activity, and the top three chains (Base, Arbitrum, zkSync) account for ~75% of cumulative fees.

The long-term chart (mid-2022 to now) also tells an important story: Finance activity didn’t grow linearly.

It exploded in 2024 – and that spike isn’t evenly distributed either.

• DEX activity dominates the entire period, start to finish.
• Automated trading starts climbing fast in late 2024 / early 2025.

Here:
> @Uniswap leads by a wide margin: multiple router versions, across multiple chains.
> @syncswap has strong multi-chain presence.
> DEX aggregators like @1inch, @odosprotocol, and @KyberNetwork consistently appear near the top.

Then you start seeing something new:
strategy executors everywhere.

Automated trading contracts show up again and again among the highest gas consumers.

That’s programmatic behavior.

Derivative activity is present too. @GMX_IO’s OrderHandler and clearing contracts show consistent usage, but still sit below spot DEXs in total gas paid.

And lending?

It’s there, but smaller.
Mostly LayerBank core contracts, capturing a noticeably lower share of Finance gas compared to trading-heavy use cases.

The takeaway is simple but important:

L2 DeFi today is still about execution, not balance sheets.
Swaps first. Automation second.
