Even though L2 gas fees aren't as high as on the ETH mainnet, they can still be quite expensive.&#x20;

Just as vectorized.eth achieved gas optimization in ERC721a, BladeSwap's core contract is dedicated to optimizing gas at every stage.

&#x20;Through an internal accounting method, it conducts only net transfers instead of token transfers for each pair in multi-hop swap paths.&#x20;

It also minimizes storage slot usage through byte packing and utilizes assembly code where necessary, creating a highly efficient codebase with the best efforts.
