## Safety
|
|
|
|
This is **experimental software** and is provided on an "as is" and "as available" basis.
|
|
|
|
While each [major release has been audited](audits), these contracts are **not designed with user safety** in mind:
|
|
|
|
- There are implicit invariants these contracts expect to hold.
|
|
- **You can easily shoot yourself in the foot if you're not careful.**
|
|
- You should thoroughly read each contract you plan to use top to bottom.
|
|
|
|
We **do not give any warranties** and **will not be liable for any loss** incurred through any use of this codebase.
