In altri mercati, come Nifty Gateway e Makersplace, i creatori devono fare domanda in anticipo.<\/p>\n\n\n\n<p>Ovviamente, se sei davvero uno sviluppatore e \/ o vuoi farlo direttamente, puoi controllare gli standard per creare NFT in ogni blockchain e selezionarne uno per iniziare da zero. Su Ethereum, abbiamo <a href=\"https:\/\/eips.ethereum.org\/EIPS\/eip-721\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">ERC-721<\/a> e ERC-1155, su EOS abbiamo gli standard SimpleAssets e dGoods, mentre in Tron c&#039;\u00e8 TRC-721. Su Counterparty \u00e8 ancora pi\u00f9 semplice, con un&#039;interfaccia amichevole da creare <a href=\"https:\/\/counterparty.io\/get-started\/#create-token\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">risorse personalizzate<\/a>.<\/p>\n\n\n\n<p><a href=\"https:\/\/www.alfa.cash\/it\" target=\"_blank\" rel=\"noreferrer noopener\">Comprare e vendere<\/a> \u00e8 pi\u00f9 semplice. <strong>Devi solo collegare il tuo portafoglio al marketplace che preferisci,<\/strong> scegli il pezzo che desideri e partecipa all&#039;asta o alla vendita diretta. Per rivenderlo, puoi farlo anche nello stesso mercato ricevendo offerte o stabilendo un prezzo.
