Wu Blockchain has learned that the Solana development team Anza tweeted that the Solana mainnet has activated the first step of SIMD-0437, reducing the storage rent unit cost from 6960 lamports per byte to 6333 lamports. This plan consists of five phases, with subsequent phases gradually lowering the cost to 696 lamports based on state growth. If issues arise with state growth, SIMD-0438 can restore the original rate.
