The Arms Deal Contract allowed players to trade ten items of the same rarity for one skin of the next tier, although the first version of the system had far more restrictions than modern contracts.<\/p>\n<h2><strong>The first contracts appeared back in 2013<\/strong><\/h2>\n<p>The Arms Deal Contract became a continuation of the development of the skin system that Valve began actively expanding after the Arms Deal Update. The principle was quite simple: a player gave away ten items of the same rarity and received one skin one tier higher in return.<\/p>\n<p>This exact basic mechanic survived CS:GO and has already been preserved in CS2. Over the years, an entire separate part of the in-game economy formed around contracts \u2014 from ordinary attempts to get rid of cheap skins to complex calculations of odds, float, and potential profit.<\/p>\n\n<div class=\"article__content grid-cards-col xl-w-100\">\n    <p class=\"article-h3\">read more<\/p>\n    <div class=\"grid-1 gap-12 mb-12 club-section__load-more-parent xl-w-100\">\n        <article class=\"club-hover-connect-parent\">\n    <div class=\"club-top-line\"><\/div>\n    <div class=\"club-row club-gutter-none\">\n                    <div class=\"club-col-4 club-col-6-xs\">\n                <figure class=\"picture-16x9 picture-with-gradient\">\n                    <a class=\"club-hover-connect club-hover-connect-img\" href=\"https:\/\/community.skin.club\/en\/news\/prediction-for-legacy-vs-g2-fissure-playground-3\" tabindex=\"-1\">\n                        <picture class=\"\">\n<source class=\"\" media=\"(max-width: 640px)\" srcset=\"https:\/\/community.skin.club\/wp-content\/uploads\/2026\/09\/HR_lTyRa0AEOHTR-768x432.jpg.webp 1x, https:\/\/community.skin.club\/wp-content\/uploads\/2026\/09\/HR_lTyRa0AEOHTR-1400x788.jpg.webp 2x\" type=\"image\/webp\">\n<source class=\"\" media=\"(max-width: 640px)\" srcset=\"https:\/\/community.skin.club\/wp-content\/uploads\/2026\/09\/HR_lTyRa0AEOHTR-768x432.jpg 1x, https:\/\/community.skin.club\/wp-content\/uploads\/2026\/09\/HR_lTyRa0AEOHTR-1400x788.jpg 2x\">\n<source class=\"\" media=\"(min-width: 641px)\" srcset=\"https:\/\/community.skin.club\/wp-content\/uploads\/2026\/09\/HR_lTyRa0AEOHTR-768x432.jpg.webp 1x, https:\/\/community.skin.club\/wp-content\/uploads\/2026\/09\/HR_lTyRa0AEOHTR-1400x788.jpg.webp 2x\" type=\"image\/webp\">\n<source class=\"\" media=\"(min-width: 641px)\" srcset=\"https:\/\/community.skin.club\/wp-content\/uploads\/2026\/09\/HR_lTyRa0AEOHTR-768x432.jpg 1x, https:\/\/community.skin.club\/wp-content\/uploads\/2026\/09\/HR_lTyRa0AEOHTR-1400x788.jpg 2x\">\n<img src=\"https:\/\/community.skin.club\/wp-content\/uploads\/2026\/09\/HR_lTyRa0AEOHTR-768x432.jpg\" srcset=\"https:\/\/community.skin.club\/wp-content\/uploads\/2026\/09\/HR_lTyRa0AEOHTR-1400x788.jpg 2x\" alt=\"\" class=\"\" loading=\"lazy\" decoding=\"async\">\n<\/picture>                    <\/a>\n                <\/figure>\n            <\/div>\n        \n        <div class=\"club-col-8 club-col-6-xs club-box-bg--gradient\">\n            <div class=\"club-box-def club-full-height\">\n                <div class=\"club-dynamic-dotted-wrap club-full-height\">\n                    <h3 class=\"club-h4-title\">\n                        <a class=\"club-link-primary club-hover-connect club-dynamic-dotted__text\" href=\"https:\/\/community.skin.club\/en\/news\/prediction-for-legacy-vs-g2-fissure-playground-3\">\n                            Prediction for Legacy vs G2 \u2014 FISSURE Playground 3                        <\/a>\n                    <\/h3>\n                <\/div>\n            <\/div>\n        <\/div>\n    <\/div>\n    <div class=\"club-bottom-line\"><\/div>\n<\/article>    <\/div>\n<\/div>\n<h2><strong>At first, the system was much stricter<\/strong><\/h2>\n<p>The first version of contracts did not allow players to simply take any ten items of the appropriate rarity. For the Arms Deal Contract, skins specifically from the Arms Deal collection had to be used \u2014 items from other collections available at the time were not accepted by the system.<\/p>\n<p>This significantly distinguished the original mechanic from the one players got used to later. The system gradually became more flexible, while the contract itself turned from a small addition to the update into one of the key tools for working with skins.<\/p>\n<h2><strong>Valve separately clarified the situation with knives<\/strong><\/h2>\n<p>One of the most interesting details of the old patch note was a separate clarification about knives. Valve immediately stated that it was impossible to receive a knife through the Arms Deal Contract, effectively shutting down one of the most obvious ideas players had for using the new mechanic.<\/p>\n<p>This rule was fundamentally important for the item economy. Knives remained a separate category of rare drops, while the contract only allowed movement between standard skin rarity tiers, without creating an alternative way to obtain the most valuable items.<\/p>\n<figure id=\"attachment_424671\" aria-describedby=\"caption-attachment-424671\" style=\"width: 1920px\" class=\"wp-caption alignnone\"><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-424671\" src=\"https:\/\/community.skin.club\/wp-content\/uploads\/2026\/09\/Valve_Lobby_2016-1.jpg\" alt=\"\" width=\"1920\" height=\"1080\" srcset=\"https:\/\/community.skin.club\/wp-content\/uploads\/2026\/09\/Valve_Lobby_2016-1.jpg 1920w, https:\/\/community.skin.club\/wp-content\/uploads\/2026\/09\/Valve_Lobby_2016-1-300x169.jpg 300w, https:\/\/community.skin.club\/wp-content\/uploads\/2026\/09\/Valve_Lobby_2016-1-1024x576.jpg 1024w, https:\/\/community.skin.club\/wp-content\/uploads\/2026\/09\/Valve_Lobby_2016-1-768x432.jpg 768w, https:\/\/community.skin.club\/wp-content\/uploads\/2026\/09\/Valve_Lobby_2016-1-1536x864.jpg 1536w, https:\/\/community.skin.club\/wp-content\/uploads\/2026\/09\/Valve_Lobby_2016-1-600x338.jpg 600w, https:\/\/community.skin.club\/wp-content\/uploads\/2026\/09\/Valve_Lobby_2016-1-1400x788.jpg 1400w, https:\/\/community.skin.club\/wp-content\/uploads\/2026\/09\/Valve_Lobby_2016-1-1200x675.jpg 1200w, https:\/\/community.skin.club\/wp-content\/uploads\/2026\/09\/Valve_Lobby_2016-1-533x300.jpg 533w, https:\/\/community.skin.club\/wp-content\/uploads\/2026\/09\/Valve_Lobby_2016-1-1067x600.jpg 1067w\" sizes=\"(max-width: 1920px) 100vw, 1920px\" \/><figcaption id=\"caption-attachment-424671\" class=\"wp-caption-text\">Photo Copyright by Valve<\/figcaption><\/figure>\n<h2><strong>The contract could literally be signed<\/strong><\/h2>\n<p>The old version of the interface was also remembered for another feature \u2014 the ability to draw directly on the contract document. Before confirming the trade-up, a player could leave their own signature, drawing, or any other scribble.<\/p>\n<p>Of course, this did not affect the result of the contract in any way, but exactly such small details created the character of the old CS:GO interface. For many players, the trade-up process itself felt much more personalized because of this than simply pressing a button.<\/p>\n<h2><strong>A whole system grew out of a simple mechanic<\/strong><\/h2>\n<p>Over 13 years, the meaning of contracts changed significantly. If at first they were primarily a way to turn ten less valuable items into one rarer item, later players began to take collections, the odds of a specific result, float, and potential market value into account.<\/p>\n<p>As a result, the ordinary Arms Deal Contract turned into a mechanic around which calculators, special strategies, and entire areas of skin trading appeared. At the same time, the fundamental principle has barely changed during all this time \u2014 ten items are given away for a chance to receive one rarer item.<\/p>\n\n<div class=\"article__content grid-cards-col xl-w-100\">\n    <p class=\"article-h3\">read more<\/p>\n    <div class=\"grid-1 gap-12 mb-12 club-section__load-more-parent xl-w-100\">\n        <article class=\"club-hover-connect-parent\">\n    <div class=\"club-top-line\"><\/div>\n    <div class=\"club-row club-gutter-none\">\n                    <div class=\"club-col-4 club-col-6-xs\">\n                <figure class=\"picture-16x9 picture-with-gradient\">\n                    <a class=\"club-hover-connect club-hover-connect-img\" href=\"https:\/\/community.skin.club\/en\/news\/g2-advanced-to-the-grand-final-of-fissure-playground-3\" tabindex=\"-1\">\n                        <picture class=\"\">\n<source class=\"\" media=\"(max-width: 640px)\" srcset=\"https:\/\/community.skin.club\/wp-content\/uploads\/2026\/09\/HN_I3X_W0AAsg5c-768x432.jpg.webp 1x, https:\/\/community.skin.club\/wp-content\/uploads\/2026\/09\/HN_I3X_W0AAsg5c.jpg.webp 2x\" type=\"image\/webp\">\n<source class=\"\" media=\"(max-width: 640px)\" srcset=\"https:\/\/community.skin.club\/wp-content\/uploads\/2026\/09\/HN_I3X_W0AAsg5c-768x432.jpg 1x, https:\/\/community.skin.club\/wp-content\/uploads\/2026\/09\/HN_I3X_W0AAsg5c.jpg 2x\">\n<source class=\"\" media=\"(min-width: 641px)\" srcset=\"https:\/\/community.skin.club\/wp-content\/uploads\/2026\/09\/HN_I3X_W0AAsg5c-768x432.jpg.webp 1x, https:\/\/community.skin.club\/wp-content\/uploads\/2026\/09\/HN_I3X_W0AAsg5c.jpg.webp 2x\" type=\"image\/webp\">\n<source class=\"\" media=\"(min-width: 641px)\" srcset=\"https:\/\/community.skin.club\/wp-content\/uploads\/2026\/09\/HN_I3X_W0AAsg5c-768x432.jpg 1x, https:\/\/community.skin.club\/wp-content\/uploads\/2026\/09\/HN_I3X_W0AAsg5c.jpg 2x\">\n<img src=\"https:\/\/community.skin.club\/wp-content\/uploads\/2026\/09\/HN_I3X_W0AAsg5c-768x432.jpg\" srcset=\"https:\/\/community.skin.club\/wp-content\/uploads\/2026\/09\/HN_I3X_W0AAsg5c.jpg 2x\" alt=\"\" class=\"\" loading=\"lazy\" decoding=\"async\">\n<\/picture>                    <\/a>\n                <\/figure>\n            <\/div>\n        \n        <div class=\"club-col-8 club-col-6-xs club-box-bg--gradient\">\n            <div class=\"club-box-def club-full-height\">\n                <div class=\"club-dynamic-dotted-wrap club-full-height\">\n                    <h3 class=\"club-h4-title\">\n                        <a class=\"club-link-primary club-hover-connect club-dynamic-dotted__text\" href=\"https:\/\/community.skin.club\/en\/news\/g2-advanced-to-the-grand-final-of-fissure-playground-3\">\n                            G2 advanced to the Grand final of FISSURE Playground 3                        <\/a>\n                    <\/h3>\n                <\/div>\n            <\/div>\n        <\/div>\n    <\/div>\n    <div class=\"club-bottom-line\"><\/div>\n<\/article>    <\/div>\n<\/div>\n<h2><strong>13 years of one of the oldest skin mechanics<\/strong><\/h2>\n<p>On September 12, 2013, contracts were only one of the new elements of the still-young CS:GO economy at the time.
