Les validateurs ou mineurs priorisent les transactions qui paient plus, donc le gas est en pratique une ench\u00e8re pour l&rsquo;espace de bloc. Sur Ethereum, il est pay\u00e9 en ETH et monte quand le r\u00e9seau est charg\u00e9, car la demande pour un espace de bloc limit\u00e9 pousse le prix vers le haut. Le gas est le co\u00fbt d&rsquo;utiliser la cha\u00eene, distinct de ce que vous envoyez.<\/p>\n<h2>Exemple chiffr\u00e9<\/h2>\n<p>Vous \u00e9changez un token contre un autre sur une bourse d\u00e9centralis\u00e9e pendant une p\u00e9riode calme et payez quelques dollars de gas. Le m\u00eame \u00e9change durant une p\u00e9riode charg\u00e9e, quand beaucoup se disputent l&rsquo;espace de bloc, pourrait co\u00fbter dix fois plus. La transaction est identique ; seule la congestion a chang\u00e9. Voil\u00e0 pourquoi minuter l&rsquo;activit\u00e9 on-chain pour les heures calmes peut \u00e9conomiser de l&rsquo;argent r\u00e9el sur Ethereum.<\/p>\n<h2>Le gas et le trading sur Volity<\/h2>\n<p>Les frais de gas s&rsquo;appliquent \u00e0 l&rsquo;activit\u00e9 on-chain comme d\u00e9placer des tokens ou utiliser la <a href=\"https:\/\/volity.io\/fr\/glossaire\/what-is-defi\/\">DeFi<\/a>, pas au trading de crypto en spot ou CFD sur une plateforme. Sur Volity, vous tradez l&rsquo;exposition crypto sans payer de gas r\u00e9seau \u00e0 chaque action, et les d\u00e9p\u00f4ts en <a href=\"https:\/\/volity.io\/fr\/glossaire\/what-is-usdc\/\">USDC<\/a> ou <a href=\"https:\/\/volity.io\/fr\/glossaire\/what-is-usdt\/\">USDT<\/a> arrivent sans frais de d\u00e9p\u00f4t. Le gas est un co\u00fbt de l&rsquo;autoconservation et de l&rsquo;usage on-chain, pas du trading sur plateforme.<\/p>\n<h2>Pourquoi c&rsquo;est important<\/h2>\n<p>Les frais de gas peuvent \u00e9clipser la valeur d&rsquo;une petite transaction on-chain durant la congestion, donc les ignorer fait perdre de l&rsquo;argent en d\u00e9pla\u00e7ant de petits montants. Minutez les actions on-chain pour les p\u00e9riodes calmes, ou utilisez des cha\u00eenes \u00e0 frais plus bas. \u00c0 lire aussi : <a href=\"https:\/\/volity.io\/fr\/glossaire\/what-is-l1-vs-l2\/\">L1 vs L2<\/a> et <a href=\"https:\/\/volity.io\/fr\/glossaire\/what-is-a-smart-contract\/\">contrat intelligent<\/a>.<\/p>\n<p>Pour aller plus loin, voir notre page <a href=\"https:\/\/volity.io\/fr\/crypto\/\">crypto<\/a>.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Comment fonctionnent les frais de gas Les frais de gas sont le paiement que vous faites pour qu&rsquo;une transaction soit trait\u00e9e sur [&hellip;]<\/p>\n","protected":false},"author":2,"featured_media":37111,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"inline_featured_image":false,"custom_schema":"","footnotes":""},"categories":[258],"tags":[],"class_list":["post-37080","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-glossaire"],"yoast_head":"<!-- This site is optimized with the Yoast SEO Premium plugin v27.7 (Yoast SEO v27.8) - https:\/\/yoast.com\/product\/yoast-seo-premium-wordpress\/ -->\n<title>Qu&#039;est-ce qu&#039;un gas fee<\/title>\n<meta name=\"description\" content=\"Un gas fee est le co\u00fbt pay\u00e9 aux validateurs blockchain pour traiter une transaction.
