Arbitrum One mainnet will migrate to Nitro on August 31st

Offchain Labs, developer of Ethereum scaling solution Arbitrum, announced that Arbitrum One is migrating to Nitro on August 31st. About a week before the mainnet migration, on August 24th, Offchain Labs is planning to carry out a shadow fork migration as a final dress rehearsal before the mainnet migration. Shadow forking allows us to run a parallel chain that copies the state of another chain and still receives incoming transactions from the main chain, in this case Arbitrum One.
