Sign's OtterSec integration answers a proof-of-audit question DeFi has quietly ignored.
A few weeks ago I was going through @Sign's documented case studies - not the marketing summaries, the actual integration details. The OtterSec proof-of-audit case stopped me longer than expected.
Here is what caught my attention. OtterSec used Sign Protocol to anchor security audit results on-chain as verifiable attestations. Not a PDF report stored somewhere. A cryptographically signed, permanently queryable record confirming that a specific audit occurred, under which scope, at which point in time. Any institution - including compliance teams at platforms like Binance evaluating projects for listing - can verify that audit record independently without contacting OtterSec or the audited project.
I had not thought about audit verification as an infrastructure problem before reading that case. I think about it differently now.
The current system asks verifiers to trust a PDF. @Sign's system gives verifiers a queryable on-chain attestation. That shift matters enormously for any institution making risk decisions about Web3 projects at scale.
