Transient Lock

An example of a lock that uses transient storage for its reentrancy guard.

The contract is implemented in src/TransientLock.sol. The tests are in test/TransientLock.t.sol.

How to use

• Use git clone git@github.com:nzmpi/TransientLock.git && cd TransientLock.

• Run forge test -vv (you need to install Foundry first).

You can notice that using transient storage for a reentrancy guard uses almost 50% less gas than using cold persistent storage, but uses more gas than using warm storage.

However, using transient storage for an approve pattern tx uses more than 90% less gas than using cold persistent storage.
