Morph, an Ethereum Layer 2 solution has introduced its Holesky testnet. This Holesky testnet was built to be advanced in its infrastructure, and it fits appropriately with the mainnet that is yet to be built. This Holesky testnet fits seamlessly with the mainnet with regards to its performance.
The holesky testnet possesses all of the advanced features, that will be part of the mainnet. As a result, in the future, it won't be any challenge moving from the holesky testnet to the mainnet. The EIP-4844's Optimistic zkEVM integration, is one of the advanced features that will be in the holesky testnet.
This particular feature will remarkably make transactions more affordable. Another advanced feature added is a restructured cross-chain system, that makes it possible for customers to be able to - in one transaction, make their withdrawals.
The interactions made by customers will be recorded in the holesky testnet. Customers will still be able to have access to their contracts on the Sepolia testnet. However, it's been suggested that developers should move to the holesky testnet.
