Here’s a chart I made of the marginal cost for one million gas on Ethereum since base fees were introduced. Log10-scaled.
The quantized steps are a brilliant hack. Nice work!
The primary effect of this EIP is to allow computation/communication gas to become cheaper in dollar terms and as a result unlocking more applications that are both storage-light and infeasible at current gas prices.

| Duplicate files (same length + same SHA-256) are moved into a DUPLICATE/ | |

Here's my opinionated philopshy on external audits and security providers. This is very specific to our current position - it's not the approach for every project.
We should never rely on external partners for our security. External partners provide additional checks, but if they find a critical, we aren't doing our job as we should be. If we miss something real and anyone downstream catches it, we should prioritize adjusting our processes to ensure that that category of issue is caught internally, every time in the future.
Some parts of the code matter more than others. We have a contract architecture that means that big pieces of our system of contracts can't lose user funds from a bug, and thus have lower security requirements. Other parts have well known interfaces which mean as long as that one or two guarantees hold, the rest can do minimal damage.

| * @notice The Vault contract stores assets. On a deposit, OUSD will be minted | |
| and sent to the depositor. On a withdrawal, OUSD will be burned and | |
| assets will be sent to the withdrawer. The Vault accepts deposits of | |
| interest from yield bearing strategies which will modify the supply | |
| of OUSD. |
This vis code is not generalized - you will need to change it to extra the code you want.
