What keeps me following $SIGN is not the faster app, but the "trust layer" behind it. In many developing markets, the issue is not just payment, but how to prove identity, access rights, or the validity of data among systems that do not trust each other.
Sign enters right there. Instead of just recording data, they turn claims into structured attestations that can be verified and reused across different systems. Supporting both public, private, and hybrid helps balance transparency and security — quite practical when viewed at an organizational scale.
The point I find noteworthy is that adoption, if any, may come from “boring” infrastructure rather than hype. When systems related to money, identity, or capital need a layer of verifiable proof, this aspect becomes more important than UI.
But the question remains: will developers use it, will organizations integrate it, and after incentives decline, who will still use it?
For me, the signal to watch is real usage — repeated integration, actual workflows, and whether attestation becomes a default part or not. If so, then the story becomes worth taking seriously.
