Polygon zkEVM Updated Parameter Recommendations (1/17/24)
Gauntlet and ChaosLabs recommend delaying all asset listings until there’s increased liquidity in LSTs and the new bridged USDC in Polygon zkEVM.
We still provide recommendations for WETH, USDC, and WMATIC should the community choose to list these assets. Due to minimal wstETH liquidity, we do not recommend listing wstETH. Consequently, the eMode category for WETH is now set to N/A. The borrow caps and IR curves for WETH and WMATIC are set anticipating the eventual listing and eMode activation of LSTs for these tokens. This approach aims to maintain IR curve consistency across markets. However, without the relevant LSTs listed, these assets will likely have minimal borrowing demand.
For these reasons and the minimal liquidity in the new USDC, we suggest delaying asset listings until there’s increased liquidity in LSTs and new USDC.
