Solana implements second phase of account rent reduction

Anza has launched the second phase of the SIMD-0437 proposal on the Solana mainnet beta, reducing the per-byte parameter for rent-exempt minimum balances to 5080 lamports. This marks a cumulative 27% decrease from initial levels, lowering the amount of SOL required to maintain rent-exempt status. Users can now withdraw excess SOL from token and mint accounts using the WithdrawExcessLamports instruction without closing accounts. Future phases remain unscheduled, pending confirmation of network stability.
