Optimism, a layer-2 solution for Ethereum, said in a post that the total supply of OP tokens was announced to expand at a rate of 2% per year, but the ratio was incorrectly set to 20% when deploying the contract, which will be released later today. Logical update to expected 2%.
Since OP’s inflation doesn’t start until next year, no new tokens are minted or moved, and any future changes to this ratio must go through governance.
