Anza confirmed that Step 1 of SIMD-0437, authored by Igor Durovic, activated on Solana’s testnet on August 27, starting a five-gate program that targets a roughly 90% reduction in the cost of creating and maintaining SPL token accounts. The proposal lowers the lamports_per_byte storage-pricing constant from 6,960 to 6,333 in Step 1, then through 5,080, 2,575, 1,322, and finally 696. Fully rolled out, a standard SPL token account’s rent-exempt deposit falls from about $0.159 to roughly $0.016, cutting capital locked for one million accounts from approximately $159,000 to $15,900 and for 100,000 accounts from about $15,900 to $1,590. Each gate activates only after state-growth review; a sixth fallback can restore 6,960, and companion SIMD-0392 preserves flexibility to raise rent later. Solana Foundation analysis cites gross daily state demand near 10 GiB versus net growth of about 0.3 GB, with 75.5% of accounts closing in the same transaction, and finds no systemic risk at projected rates, including that a state-bloat attack would still need roughly $17.2 million in locked capital. The work ships in Agave 4.2 with sub-400ms slot times and larger maximum transaction sizes, following a 300ms slot reduction already on testnet, and remains especially material for payments and stablecoin apps after Solana payment volume rose 755.3% in 2025 with settlement use by brands such as Western Union, PayPal, and Fiserv.
