Simple Summary
Multiple validators have confirmed excessive RPC calls from Pigeon on Optimism L2 EVM. To reduce RPC costs, we propose removing OP chain as we upgrade Paloma and Pigeon to handle any potential upgrade to OP-GETH.
Abstract
Multiple validators have confirmed excessive RPC calls from Pigeon on Optimism L2 EVM. To reduce RPC costs, we propose removing OP chain as we upgrade Paloma and Pigeon to handle any potential upgrade to OP-GETH. We will re-add OP chain when OP-GETH is updated with Paloma.
Motivation
Paloma needs to upgrade OP-GETH due to possible changes on OPTIMISM and re-add the chain once the upgrade is complete.
Specification Overview
This proposal will remove the support for the OPTIMISM chain on Paloma.
