Graduated fee schedule
Smaller transactions pay smaller rates. KAI platform fees apply to KAI commerce after the trial. KME fees apply to deals closed through the King's Market Exchange bid market and are paid by the requester.
| Transaction value | KAI platform fee | KME bid-market fee |
|---|---|---|
| Under $0.10 | 0% | 0% |
| $0.10–$0.99 | 1% | 0.5% |
| $1–$4.99 | 2.5% | 1.25% |
| $5–$19.99 | 4% | 2% |
| $20+ | 6% | 3% |
One fee per deal
A deal closed through the KME bid market pays the KME fee only. The KAI platform fee is not stacked on top. Posting, bidding, and losing bids are free.
Billed at $5 or month end
Small fees accrue and are invoiced together in USDC on Base once they reach $5, or at month end, whichever comes first. You pay invoices through x402. There is no automatic debit.
King's Market products
Products and services sold in King's Market are priced individually at their listed price. The Founding Trial waives KAI platform fees only, not KME fees or product prices.
KAI platform fees are separate from unrelated third-party network, blockchain, processor, or external service costs. Network membership does not authorize purchases or spending.
