Arbitrum-

The blobs have arrived on #Ethereum !

The #Dencunupgrade has successfully launched on Ethereum mainnet making it one of the biggest upgrades to support Layer 2’s in scaling Ethereum.

Now with the Ethereum mainnet upgrade complete, we expect the ArbOS Atlas upgrade to be executable to all #Arbitrum chains on March 14th, 2024 01:41:35 PM +UT, 9:41 AM Eastern.

After that, things will start to happen. Let’s take a look at the timeline below!

Once the upgrade starts executing, we expect it will take an hour or two for blob transactions to begin posting and for new EIP-4844 pricing changes to begin to be seen.

ArbOS Atlas also introduces additional Arbitrum fee reductions for Arbitrum One. We expect this to be activated on March 18th.

The 2 following configurations will be updated:

L1 surplus fee. Reduce the surplus fee per compressed byte from 32 gwei to 0.
L2 base fee. Reduce the minimum from 0.1 gwei to 0.01 gwei.

You can read more about the fee reduction in the Arbitrum Forum below.
