Son objectif : <strong>rester stable face au dollar<\/strong>. Le syst\u00e8me repose sur des m\u00e9canismes automatiques. Il cr\u00e9e ou d\u00e9truit des jetons DOT selon les besoins.

Des propositions concr\u00e8tes sont d\u00e9j\u00e0 soumises au vote. Ce stablecoin pourrait <strong>acc\u00e9l\u00e9rer l\u2019adoption du r\u00e9seau<\/strong>.

Aucun acteur principal ne contr\u00f4le les r\u00e9serves.<\/p>\n<p>Mais le souvenir de TerraUSD reste vif. Son effondrement en 2022 a marqu\u00e9 les esprits. Le mod\u00e8le algorithmique inqui\u00e8te de nombreux analystes. Le risque principal : la volatilit\u00e9 du DOT. Un d\u00e9sancrage peut d\u00e9clencher une spirale n\u00e9gative. Cela pourrait stresser tout le march\u00e9 crypto. Polkadot doit cr\u00e9er un m\u00e9canisme tr\u00e8s solide. Objectif : <strong>\u00e9viter un sc\u00e9nario catastrophe<\/strong>.<\/p>\n<p>Sur X, PolkaWorld relaie activement les avanc\u00e9es du projet.
