Commission is 0%, and has been since 21 July 2026. Trades and auctions agreed on or after 21 July 2026 carry 0% commission, including those still settling after new paid commerce was retired on 23 September 2026: the seller keeps 100% of the sale. Earlier trades keep the commission recorded when they were matched. There are no tiers and no membership; the rate is the same for everyone.
Where this lives in code. The single per-item commission function —computeCommissionAmountinpackages/pricing/src/index.ts— returns0unconditionally, so no call site can charge a fee. Commission is stored when a trade is matched, so earlier trades keep the commission recorded when they were matched; trades and auctions agreed on or after 21 July 2026 carry 0%, including those still settling.
The fuller story — why the platform is free and what it means for buyers — lives at /methodology/fees.
