# Function May Run Out Of Gas Leading To Loss

### Summary:

<https://github.com/code-423n4/2022-09-frax-findings/issues/17>

`frxETHMinter.depositEther` always iterates over all deposits that are possible with the current balance. However, when a lot of ETH was deposited into the contract / it was not called in a long time, this loop can reach the gas limit. When this happens, no more calls to `depositEther` are possible, as it will always run out of gas.

### Proof Of Concept:

Jerome Powell continues to rise interest rates, he just announced the next rate hike to 450%. The crypto market crashes, ETH is at 1 USD. Bob buys 100,000 ETH for 100,000 USD and deposits them into `frxETHMinter`. Because of this deposit, `numDeposit` within `depositEther` is equal to 3125. Therefore, every call to the function runs out of gas and it is not possible to deposit this ETH into the deposit contract.

### Mitigation:

It should be possible to specify an upper limit for the number of deposits such that progress is possible, even when a lot of ETH was deposited into the contract.
