Since Discord's 2023 shift to unique global @usernames, 4-letter handles have settled in as the platform's most commonly traded "accessible" tier — rare enough to matter, common enough to actually find listed.
If servers or Nitro status are bundled with the account, yes — that's priced separately from the handle itself, and worth clarifying with the seller.
Open the vault, pick a listed username, and DM the contact handle shown on the site to arrange payment — there's no cart/checkout, it's a direct conversation with the seller.
Crypto-only. See the Terms of Service for the full payment and delivery policy, including the sale-finality and 72-hour issue window.
