The second phase of Solana account rent reduction is now live, with a cumulative decrease of 27% from the initial level

Anza announced that the second phase of the Solana account rent reduction proposal SIMD-0437 has been launched on the mainnet beta. In epoch 1033, the per-byte parameter used to calculate the minimum balance for rent-exempt accounts has been reduced from 6333 lamports to 5080 lamports, a cumulative decrease of about 27% from the initial level, lowering the SOL balance required to maintain rent-exempt status.

Anza also shared instructions for reclaiming excess SOL: users with the appropriate permissions can use the WithdrawExcessLamports instruction to withdraw SOL from token accounts, token mint accounts, etc., that exceed the minimum balance for rent exemption, without needing to close the accounts, and it does not affect the token balance. There is no fixed timeline for subsequent phases; the third phase will only be activated after confirming that the on-chain status growth is within a safe range; adjustments can be made in reverse through SIMD-0438 if necessary.
