EIP-1153 introduces a new “transient storage” option within the Ethereum blockchain. This storage is temporary, meaning data within it is automatically deleted after a transaction finishes. It’s much cheaper to use than regular storage and is ideal for passing information between different parts of a smart contract within a single transaction.
This leads to lower gas fees and opens up new ways to optimize smart contracts. However, it’s important to remember that transient storage is not for permanent data, as it’s wiped clean between transactions.
