The cryptocurrency world has a dark humor: 'Code has been audited' is roughly equivalent to 'hasn't been hacked yet.'
But to be honest, seeing USDD 2.0 release 5 independent audit reports all at once left me a bit stunned. These days, there aren't many projects willing to spend so much on security.
Don't listen to PR hype about 'AA-rated'; what I value are these two details:
1. Who is checking? (ChainSecurity is a tough player)
This time USDD hired CertiK and ChainSecurity.
CertiK is well-known, scoring 87.5, which is decent. But ChainSecurity is truly hardcore, being the audit firm used by the Ethereum Foundation, notorious for being picky.
Daring to throw the contract code to these two firms for 5 rounds of checks shows that the project team is either truly technically confident or really scared of failure—this is good for users.
2. Binance's endorsement
Getting on Binance is one thing, getting into Binance Wallet Yield+ is another.
This time, USDD's ability to launch in Binance Wallet's wealth management section (while also issuing a 300,000 USDD reward) means it passed Binance's internal risk control team's 'hell-level' due diligence. Everyone knows how picky Binance is about listing coins; passing this hurdle is far more effective than trying to read the code yourself.
Summary:
In the DeFi world, there is no absolute security; code is written by humans and can have bugs.
But compared to those who dare to run naked with an unknown audit report, USDD 2.0's defensive attitude, which is fully stacked, at least makes me feel a bit more secure putting money in, even while sleeping.
