Gas Saving Matters : Benchmark

Saving on transaction costs is like gaining free liquidity.

*To standardize the value, calculated with gas price=30gwei, ETH=2000$ with the table below

Dex	Velocore V2	U** swap (V3)	P** swap	i** swap	k** swap
ETH->USDC swap	104069	127543	184329	197983	246445
Swap with 1 hop (ex. ETH->USDC-> USDT )	144093	235295	258926	579632	396242
Add ETH-USDC LP	148185	401924	511149	614200	459928

The chart above shows how much gas is consumed by the following actions on each Dex: simple swap (without routing), routed swap (with only 1 hop), and add liquidity.

*For an intuitive comparison, the graph is plotted as a transaction cost using the current gas price of 15gwei on the Linea testnet multiplied by the ETH price of $2000.

From the above data, you can see that using Velocore can save you or your buyers 0.7$ ~ 8$, or 30~75% on EVERY action! The difference gets larger when there is chain congestion. Considering that the price impact difference between a regular DEX and a concentrated liquidity DEX is less than 0.2% for a typical trade, this makes a huge difference.

Looking at zkSync's statistics, we can see that the average size of a swap across all dexes is only between $100 and $150. Saving even $1 on gas is equivalent to reducing the price impact by 1%, which is equivalent to getting 100k~500k in liquidity for free.

In general, on Ethereum-based chains, reducing gas costs is most beneficial when the swap size is $10k or less.
