This release signifies a WASM fraud proof consensus version, and is not a good version to run a node on

WAVM Module Root: 0xf4389b835497a910d7ba3ebfb77aa93da985634f3c052de1290360635be40c4a

This contains the following consensus changes from consensus v10:

1. EVM Shanghai support (including the PUSH0 opcode)

Recent versions of go-ethereum already includes support for the changes to the EVM made in the Shanghai L1 upgrade, but we need to enable them for Arbitrum chains. Instead of using a time based activation, it’s better to activate support based on the ArbOS version, which makes sure that even if the upgrade is delayed, Shanghai support will take effect uniformly and without causing divergences with out of date node software.

2. Retryable fixes

Retryable fees previously always used the network fee account, instead of also using the infrastructure fee account. The infrastructure fee account should be paid fees from the basefee, and the network fee account should be paid any surplus fees when the gas price is elevated. That was correctly implemented for normal transactions, but retryables only dealt with the network fee account. Retryable redemption also reported an incorrect gas usage in the block header. This matters to Arbitrum Nova, where the infrastructure fee account pays out some fees to the Data Availability Committee members, but the network fee account does not.

3. Fix the chain owner list returned by precompile

This change doesn’t affect the actual chain owner set, but the list being returned by the ArbOwnerPublic precompile was incorrect for Arbitrum Nova due to an internal ArbOS issue. To be clear, this does not affect who was able to make chain owner actions. As intended, only the DAO is able to make chain owner actions on Arbitrum One and Arbitrum Nova. This change only affects the list of chain owners presented by the ArbOwnerPublic precompile.

4. Fix some precompile methods taking up all gas when reverting

Some precompile methods such as ArbSys’s arbBlockHash method took up all gas when reverting. That meant that if a transaction called arbBlockHash with an out-of-range block number, it’d use up all the gas when reverting.

PR:

5. Create missing precompile methods to view some L1 pricing parameters

The L1RewardReceipient and L1RewardRate were previously not exposed via precompiles. This change adds methods to get them to ArbGasInfo so that the current chain configuration can be easily checked.

PR:

6. Fix the possibility of a staticcall from the owner to ArbOwner emitting a log

This shouldn’t matter in practice, but it was theoretically for a staticcall from the chain owner to the ArbOwner precompile to emit a log. In the EVM, staticcalls should never be able to emit logs. This PR fixes the Arbitrum precompile logic to disallow emitting logs in staticcall contexts.

PR:

7. Fix default L1 pricing params

This shouldn’t matter for Arbitrum One and Arbitrum Nova, because these parameters were already corrected in AIP-7. However, it’s included in ArbOS version 11 so that any Arbitrum Orbit chains automatically get the correct parameters.
