Sponsored Fees

Let your buyers pay an exact, predictable price without worrying about gas fees! Sponsored Fees allows the seller to pay network and service fees on behalf of the buyer's card or ETH payment.

Quickstart

  1. Connect a payment method and top up your Sponsored Fees credits.
    1. And automatically top-up when your credits falls below $20.
  2. Configure your Shareable Checkout Link or One-Time Checkout Link to sponsor fees.
  3. Buyers pay for the blockchain price of the NFT -- no hidden fees or spread. Network and service fees will be deducted from your credits.

Use cases

  • Give buyers to have a fee-less experience: A 25 USDC purchase will cost exactly $25 USD.
  • Allow buyers to receive a free NFT with just a "Claim" button -- no payment required.

Prerequisites

🚧

Ethereum network fees can be expensive!

Gas fees can range from $3 to $15 depending on network congestion for each NFT minted on Ethereum.

We recommend Polygon for large-scale projects.
