The Foundation marketplace allows for artists to split the revenue from primary sales and royalties across multiple addresses. This feature will be used to route a percentage of the proceeds directly to the Ethereum Foundation.

The running average of the last 10 completed primary sales will be used to determine the exact percentage that each new NFT will be minted with. For example, if the running average of the last 10 sales is 1.0 ETH, then tier #10 would be used for minting the next NFT, and 45% of proceeds for that NFT would be routed directly to the Ethereum Foundation.

The first listings starts at bracket #6 with a 25% contribution to the Ethereum Foundation. After the first auction has been completed, the running average system kicks in.
