Solana account rent proposal SIMD-0437 has entered its second phase on mainnet beta at epoch 1033. The parameter used to calculate the minimum rent-exempt account balance fell from 6,333 lamports per byte to 5,080 lamports, a cumulative decline of about 27% from the initial level. The change reduces the SOL required to keep accounts rent-exempt. Anza said authorized users can use the WithdrawExcessLamports instruction to recover excess SOL above the rent-exempt minimum from token accounts and token mint accounts without closing them or affecting token balances. No fixed schedule has been set for the next phase. Phase three will activate after on-chain state growth is confirmed to remain within a safe range, while SIMD-0438 provides a mechanism to reverse the changes if necessary.
