It’s cheaper to swap on layer-2s than on Ethereum, Uniswap research finds

A latest paper by Austin Adams, a researcher at Uniswap Labs, contends that swapping and liquidity provisions on layer-2 networks are considerably cheaper than on Ethereum’s mainnet.

Based on the paper, chains like Arbitrum created over thrice extra liquidity positions this previous 12 months than Ethereum.

The report additional reveals that, when taking a look at USDC/ETH swimming pools, 97.5% of swappers with trades below $125,000 did higher on layer-2s than on Ethereum mainnet.

That is seemingly as a result of retail swappers, with trades below $125,000, are more likely to profit from the decrease fuel prices and better liquidity focus on layer-2s than the mainnet.

It’s price noting that Ethereum is liable for solely round 25% of the overall transaction rely however over 60% of the amount — demonstrating that, regardless of boasting increased transaction volumes, community exercise continues to be predominantly on layer-2s.

Moreover, layer-2s usually supply shorter block instances, or the time it takes the community to provide a brand new block. On Ethereum at present, the common block time is roughly 12 seconds. On Arbitrum, then again, the common block time is round 0.26 seconds.

The shorter the block time, the much less alternative there can be for the market worth of an asset to maneuver, that means that arbitrage makes an attempt will seemingly not be as worthwhile.

Much less profitable arbitrage makes an attempt are factor for liquidity suppliers, who’re making 20% extra in returns from arbitrage on layer-2s than they’re on mainnet, the paper reveals.

Though there are vital advantages for customers to commerce on layer-2s, the paper does notice drawbacks. One major concern is the centralized sequencer.

The paper notes that many present rollups at present nonetheless function below one centralized sequencer. This sequencer may make the most of the scenario by reordering transactions to maximise MEV income for themselves.

Moreover, optimistic rollups at present would not have decentralized fraud proofs, that are essential to right sequencer errors.

Lastly, there are over 40 layer-2 ecosystems current at present. The proliferation of those networks means additional liquidity fragmentation, as they can’t trustlessly converse to at least one one other in actual time. Which means that they might want to depend on bridging infrastructure, which is each pricey and time-consuming.

The builders of layer-2 networks are working to deal with these considerations. Optimism not too long ago revealed a permissionless fault-proof system, whereas shared sequencer networks like Espresso have explored methods to diversify sequencers for rollups.

“For decentralized markets to satisfy their full potential, combination buying and selling prices should proceed to say no and person expertise should proceed to enhance,” Adams wrote. “We imagine that the studied generalized layer-2s nonetheless have many advantages that customers can make the most of at present, and any future enhancements will solely proceed to profit the buying and selling expertise.”
