Getting an audit or even a few audits completed by reputable auditing firms such as Quantstamp, Trail of Bits etc to help provide a higher degree of security for those staking their assets inside the Method NFT vaults.
The idea around Method NFT vaults keeping assets secure is appealing to users so this should be really taken seriously.
If the project itself were to ever get hacked this could really damage the long term image of the project (like how Cover Protocol, an insurance provider was hacked or just recently the xToken project which is a competitor and similar to Method Finance got hacked).
Once a hack occurs, that fear stays with people for a long time so I hope Method can take every precaution possible to ensure security is at a world-class level.
