Memory Expansion Costs

Memory expansion costs refer to the increasing gas fees incurred as a contract uses more memory during execution. In the Ethereum Virtual Machine, the first few words of memory are cheap, but the cost grows quadratically as more memory is allocated.

Developers must be mindful of how much data they load into memory, especially when processing large arrays or complex data structures. Optimizing memory usage involves clearing unnecessary data and reusing existing buffers.

This is particularly relevant for high-performance trading engines and data-heavy applications. By managing memory effectively, developers keep gas costs predictable and low.

It is a key aspect of building scalable and efficient decentralized protocols.
