Neodymium comment on the significance of open supply code to get listeners concerned and assist repair these sorts of bugs. He said:
We imagine probably the most safe code is open supply, and as auditors we imagine that among the best methods to put in writing higher code is to know vulnerabilities.
After discovering this feat, Neodymium shared its existence with groups who would possible use this system as a device for his or her operations. Amongst these had been some protocols that aren’t open supply on the Solana channel and can’t be verified immediately by their customers.
