-GIVbacks are distributed in two different blockchains, Gnosis and Optimism. All donations made in eligible tokens on Mainnet, Gnosis, Polygon or Celo will be rewarded with GIV on Gnosis chain; and the ones made in eligible tokens on Optimism will be rewarded with GIV on Optimism. 
+GIVbacks are distributed in two different blockchains, Gnosis and Optimism. All donations made in eligible tokens on Mainnet, Optimism, Polygon, Celo, or ETC will be rewarded with GIV on Optimism Network; and the ones made in eligible tokens on Gnosis chain will be rewarded with GIV on Gnosis. 
 
 Givers are able to claim their GIV after the round ends and a fraud review has been conducted. Donors will receive an email when the rewards are ready to be claimed on the [GIVbacks page](https://giveth.io/givbacks). A portion of the GIV will be liquid immediately, and the rest will increase the flowrate of their [GIVstream](https://giveth.io/givstream). To learn more about the GIVstream and how it works, check out our [documentation](https://docs.giveth.io/giveconomy/givstream/). For the purposes of this documentation, we will refer to the sum of the liquid amount and the amount allocated to the GIVstream from GIVbacks as `cumulative GIVbacks`.
