Arbitrum(ARB) Arbitrum One is migrating to Nitro on August 31st

Arbitrum One is migrating to Nitro on August 31st! One week ago Offchain Labs carried out the migration of the Arbitrum Rinkeby testnet to Nitro. They're excited to share that they're targeting the migration to take place on August 31st — exactly a year after the first opened Arbitrum One up in public beta! Nitro is a significant technical upgrade, bringing changes across the stack that dramatically improve the experience of building on Arbitrum.
