The incident was commented on by Harry Kalodner, co-founder and chief technology officer of Offchain Labs, the company behind Arbitrum.
Today was a tough day. A lot of lessons learned and work to do to make sure Arbitrum can deliver the excellence people rightly expect. Engineering in web3 is hard, but we’re all in this together to build a better future

In June, an error in Arbitrum’s sequencer mechanism led to a brief pause in executing Ethereum transaction packets.
In October, Offchain Labs opened the ability to launch L3 networks on the mainnet.
