According to the Optimism governance forum, the Optimism Foundation has proposed returning a portion of sequencer fees to ecosystem partners that drive key business activity on OP Mainnet. The rebate funds will come from ETH transaction fee revenues generated by the relevant transactions, not OP tokens.
The proposal sets rebates not to exceed the fees generated by each partner and requires achieving activity milestones, fixed partnership terms, and performance benchmarks. The Foundation plans to disclose the total rebate amount as a percentage range of sequencer and priority fee revenues in annual budget reports. The proposal awaits governance approval.
