Is there any comprehensive documentation on how gas metering works across EVM chains?

this is something I would love to see explained in rollup.codes

There are application-level features dependent upon opcode prices and overall gas logic.

Isn't equivalent gas metering required to be EVM-equivalent?

Are there EVM rollups that changed their gas metering?

Rollups have the L1 data fee that mainnet doesn’t. So you either:
- Bake that into the gas limit (arbitrum), so you still only have gas price and gas limit, but an ETH send uses ~400k gas and fluctuates based on L1 gas price
- Add L1 gas limit and price fields (Optimism), so L2 gas and cost matches the EVM

It looks like Arbitrum no longer charges ~400k gas.

I've just done a simple ETH transfer now, and it cost ~37k gas. In July 2023, it cost 411k gas to do this.

Is this due to EIP-4844?

Ah interesting, yea that must be the reason—everything above the standard 21k is the L1 cost, and L1 costs went down a lot with 4844
