simd-0437

According to Anza's monitoring, the second step of the Solana proposal SIMD-0437 rent reduction will take effect on the mainnet at approximately 21:15 UTC, corresponding to epoch 1033. At that time, the lamports required per byte will decrease from 6333 to 5080, a cumulative decrease of about 27% from the initial level, and the deposit required for on-chain storage such as creating token accounts will be further reduced.There is currently no fixed timetable for subsequent steps; the third step will be initiated once the growth of on-chain status is confirmed to be safe. If any anomalies occur, SIMD-0438 can serve as a fallback mechanism to revert the rent parameters. Currently, three steps remain in the five-step plan.

The core development team of Solana, Anza, announced that the Solana testnet has enabled the first phase of the SIMD-0437 proposal, and the account rent reduction mechanism has begun testing. This proposal includes a total of 5 functional gates, with only the first functional gate currently activated, and all adjustments have not yet been completed and deployed to the mainnet.Once all 5 phases are completed, the storage cost parameter lamports_per_byte for Solana will be reduced from 6960 to 696, resulting in an overall reduction of 90%. For example, in the case of token accounts, the deposit required to maintain an account in a rent-exempt state is expected to decrease from approximately $0.16 to $0.016, thereby lowering the costs of account creation and application deployment.
