Abstract

While attempting to return tokens from EVM to Paloma, a bug was found in the PalomaERC20 token contract for GRAIN on the target EVM chains. This vote will upgrade Paloma GRAIN token address on the target EVM chains for Ethereum, Arbitrum, Optimism, Base, Polygon, BNB, and Gnosis with the verified contracts on each chain.

The balance calculation of token sending across the Skyway Bridge to Paloma was incorrect. All PalomaERC20 contracts were upgraded
