EIP-1153 introduced a transient storage mechanism to Ethereum, allowing storage to be utilized only for the duration of a transaction. This EIP facilitates cleaner smart contract designs and allows for more gas optimisations. Essentially, it introduces a new writable location for data that persists only for the duration of a transaction. Since the blockchain has no need to retain transient data post-transaction, nodes will not need to store this data on disk as well, making it much cheaper as compared to regular storage.
Transientoor achieves gas efficiency through the use of tload and tstore operations, each consuming 100 gas, to update the allowance of owner and spender pairs. This is a significant improvement over the conventional sload and store opcodes, which cost 2,100 gas (for setting a storage slot from 0 to non-zero) and 100 gas (for updating a non-zero value), respectively.
Since we can temporarily grant users the ability to spend our ERC20s, we can abstract away the "approval" step when dealing with ERC20s, especially with DEXes. We have created a Chrome extension that modifies Uniswap's interface to swap tokens without the need for approval, which can be found at https://transientoor.vercel.app/about. Note that these tokens will need to support the transient opcode feature, an example can be found in our contracts repo.
In our ERC721 standard, when you "lend" an NFT, we store the deadline on chain to indicate when you can retrieve the NFT back from the borrower. We also store your information as the original owner of the NFT for retrieval purposes.
Then, after the deadline, you can retrieve the NFT back immediately from whoever the current owner is, without having to worry about who has "borrowed" / "sold" it away.
This is currently available on our main site at https://transientoor.vercel.app/.
