Anza said phase two of Solana account rent reduction proposal SIMD-0437 is now live on mainnet beta. Starting in epoch 1033, the per-byte parameter used to calculate the minimum balance required for rent exemption was reduced from 6,333 lamports to 5,080 lamports. According to Anza, that brings the cumulative reduction to about 27% from the initial level and lowers the amount of SOL needed to keep accounts rent exempt. Anza also outlined how excess SOL can be reclaimed: users with the required authority can use the WithdrawExcessLamports instruction to withdraw SOL above the rent-exempt minimum from token accounts, token mint accounts and similar accounts, without closing those accounts or affecting token balances. There is no fixed launch schedule for the remaining phases. Anza said phase three will only be activated after confirming that on-chain state growth remains within a safe range, and that SIMD-0438 could be used to reverse the adjustment if needed.
Anza said phase two of Solana account rent reduction proposal SIMD-0437 has gone live on mainnet beta.
Beginning in epoch 1033, the per-byte parameter used to calculate the minimum balance required for rent exemption was cut from 6,333 lamports to 5,080 lamports. Anza said the change brings the cumulative reduction to about 27% from the initial level, lowering the amount of SOL needed to keep an account rent exempt.
Anza also shared guidance on reclaiming excess SOL. Users with the relevant authority can use the WithdrawExcessLamports instruction to withdraw SOL above the rent-exempt minimum from token accounts, token mint accounts and similar accounts. The process does not require closing the account and does not affect token balances.
As for what comes next, Anza said there is no fixed launch timetable for later phases. Phase three will only be activated after confirmation that on-chain state growth is within a safe range. If necessary, the adjustment can be reversed through SIMD-0438.
