CX CDX Auction

Built without 500 staff and 500K titles

Seller pricing that undercuts the mess

CDX is automated first: cron closes lots, scores value, ships labels, digests sellers. That means we can price under eBay and Whatnot and still stay healthy — without a floor full of account managers. Coin proceeds always pay the selling dealer (company rails). Platform fees are separate ledger / prepaid credit.

Example sold price

Illustrative marketplace models — not legal quotes. Your card processor fees on your rails still apply when buyers pay you. CDX does not hold coin settlement funds.

How public sellers will be billed (plumbing live)

  1. Accrue on sold — final-value fee lands in cdx_auction_fee_ledger when the lot closes sold.
  2. Prepaid credit wallet — top up fee balance; sold lots debit credit first.
  3. Unpaid accrual — if credit is short, balance sits as unpaid (monthly invoice / block new lists when over threshold — at open).
  4. SpotPro members stay $0 — approved member plan never competes with your SpotPro subscription value.
  5. Allowlist still closed — public signup for freestanding sellers is gated until trust + billing UX are battle-tested.
