 ## L2 vs L1: Benefits of using Nimbora
 
-The main benefit of using Nimbora is the decreases in gas fees, up to 7x compared with Ethereum mainnet. This significant reduction in gas fees is achieved through the utilization of innovative Layer 2 solutions. These solutions perform most transactions off-chain, only settling the final state on the Ethereum mainnet. This drastically reduces the number of transactions that need to be processed on the congested Ethereum network, thereby reducing overall gas fees. This makes transactions on Nimbora more affordable and accessible for all users, fostering a more inclusive DeFi ecosystem.
