The proposal payload executes the following actions:

1. SetWasmModuleRootAction for Arbitrum One - Will update the WASM Module Root for ArbOS51 by calling setWasmModuleRoot(0x8a7513bf7bb3e3db04b0d982d0e973bcf57bf8b88aef7c6d03dba3a81a56a499) on the Arbitrum One rollup contract.
2. SetWasmModuleRootAction for Arbitrum Nova - Will update the WASM Module Root for ArbOS40 by calling setWasmModuleRoot(0x8a7513bf7bb3e3db04b0d982d0e973bcf57bf8b88aef7c6d03dba3a81a56a499) on the Arbitrum Nova rollup contract.
3. UpgradeArbOSVersionAtTimestampAction for Arbitrum One - Will call ArbOwner::scheduleArbOSUpgrade(51, 1767891600) on Arbitrum One. This will schedule the upgrade to ArbOS 51 at Unix timestamp 1767891600.

   • Set the new minimum L2 base fee to 0.02 gwei, by calling ArbOwner::setMinimumL2BaseFee(20000000)
   • Set the new gas floor per token to 10, by calling ArbOwner::setParentGasFloorPerToken(10)
   • Add the ResourceConstraintManager contract as a chain owner, by calling ArbOwner::addChainOwner(0x8F59C7A53b883563B34cbBb6fF021B03973e823a)
6. ArbOS50SettingsAction for Arbitrum Nova - Will modify the following settings:
   • Set the new minimum L2 base fee to 0.02 gwei, by calling ArbOwner::setMinimumL2BaseFee(20000000)
   • Set the new gas floor per token to 10, by calling ArbOwner::setParentGasFloorPerToken(10)
   • Add the ResourceConstraintManager contract as a chain owner, by calling ArbOwner::addChainOwner(0x653e31e11769a9c6feE825E4BC822753DE2286B7)
