The MIP-8 upgrade changes how the network charges contracts for reading storage, replacing slot-by-slot warming with groups of 128 consecutive slots.<\/p>\n<p>Monad&#8217;s mainnet block 101672712 measured 8,100 gas to read slot 0, 100 gas to read slot 1 on the same page, and 8,100 gas again at slot 128, the first slot of the next page.<\/p>\n<p>The official MonadTen release record sets activation at Unix timestamp 1788359400. Below that timestamp, MonadNine rules remained in force.<\/p>\n<h2>Storage layout now changes the bill<\/h2>\n<p>The final MIP-8 specification defines a storage page as 128 words of 32 bytes each, or 4,096 bytes. The first SLOAD anywhere on a page costs 8,100 gas. Later reads anywhere inside that warmed page cost 100 gas for the rest of the transaction, subject to rollback when a call frame reverts.<\/p>\n<p>Under Monad\u2019s prior schedule, two previously untouched slots each cost 8,100 gas even when they sat next to each other. Under the new opcode pricing, the same pair costs 8,100 gas and then 100 gas if both fall within one page.<\/p>\n<figure id=\"attachment_560261\" aria-describedby=\"caption-attachment-560261\" style=\"width: 720px\" class=\"wp-caption aligncenter\"><img fetchpriority=\"high\" decoding=\"async\" class=\"wp-image-560261\" src=\"https:\/\/cryptoslate.com\/wp-content\/uploads\/2026\/09\/exec-e93085b1-55de-4f82-90df-4551ae4f09f7.png\" alt=\"Diagram showing Monad MIP-8 charging 8,100 gas for the first storage read in a 4KB page, 100 gas for later reads on that page, and 8,100 gas again at the next page boundary.\" width=\"720\" height=\"1080\" srcset=\"https:\/\/cryptoslate.com\/wp-content\/uploads\/2026\/09\/exec-e93085b1-55de-4f82-90df-4551ae4f09f7.png 1024w, https:\/\/cryptoslate.com\/wp-content\/uploads\/2026\/09\/exec-e93085b1-55de-4f82-90df-4551ae4f09f7-200x300.png 200w, https:\/\/cryptoslate.com\/wp-content\/uploads\/2026\/09\/exec-e93085b1-55de-4f82-90df-4551ae4f09f7-683x1024.png 683w, https:\/\/cryptoslate.com\/wp-content\/uploads\/2026\/09\/exec-e93085b1-55de-4f82-90df-4551ae4f09f7-768x1152.png 768w\" sizes=\"(max-width: 720px) 100vw, 720px\"\/><img decoding=\"async\" class=\"lazyload wp-image-560261\" src=\"https:\/\/cryptoslate.com\/wp-content\/uploads\/2026\/09\/exec-e93085b1-55de-4f82-90df-4551ae4f09f7.png\" alt=\"Diagram showing Monad MIP-8 charging 8,100 gas for the first storage read in a 4KB page, 100 gas for later reads on that page, and 8,100 gas again at the next page boundary.\" width=\"720\" height=\"1080\" srcset=\"https:\/\/cryptoslate.com\/wp-content\/uploads\/2026\/09\/exec-e93085b1-55de-4f82-90df-4551ae4f09f7.png 1024w, https:\/\/cryptoslate.com\/wp-content\/uploads\/2026\/09\/exec-e93085b1-55de-4f82-90df-4551ae4f09f7-200x300.png 200w, https:\/\/cryptoslate.com\/wp-content\/uploads\/2026\/09\/exec-e93085b1-55de-4f82-90df-4551ae4f09f7-683x1024.png 683w, https:\/\/cryptoslate.com\/wp-content\/uploads\/2026\/09\/exec-e93085b1-55de-4f82-90df-4551ae4f09f7-768x1152.png 768w\" data-sizes=\"(max-width: 720px) 100vw, 720px\"\/><figcaption id=\"caption-attachment-560261\" class=\"wp-caption-text\">Diagram shows MIP-8 charging 8,100 gas for each new 4KB page\u2019s first SLOAD, while subsequent warmed slots cost 100 gas.<\/figcaption><\/figure>\n<p>Common Solidity layouts can inherit that discount automatically.
