CoinVoice recently learned that Optimism posted on social media that the revenue from the Superchain sorter will be used for Retro Funding. In May, the total contribution from all members of Superchain was about 812 ETH. In addition to the OP Collective allocation, the Retro Funding pool mainly comes from two sources:

100% of OP Mainnet profits; 2.5% sorter income or 15% sorter profit of each superchain member (whichever is higher);

Collective Contribution Quantity:

As May is coming to an end, OP Collective expects a total contribution of approximately 812 ETH, with funds coming from OP Mainnet, Mode, Zora, Base, Metal L2 and Frax Finance; OP Collective's average daily contribution = 27 ETH/day.

On-chain builders who deploy contracts on the Hyperchain are contributing revenue to the OP Collective and contributing to Retro Funding. [Original link]
