I am generally immune to the term "Web3 version of XX." Web3 version of Uber, Web3 version of YouTube, Web3 version of WeChat—I've heard it too many times, and very few have survived. So when I saw someone refer to the @SignOfficial Sign App as a "Worldcoin-style super application," my first reaction was: here we go again.

But I still tried downloading it.

Let's talk about the data. The Orange Dynasty App has been online for 14 days, with 400,000 subscriptions, 100,000 verified users, 1.5 million monthly active users, and 3 million downloads. This growth rate is very rare among Web3 products. In comparison, most DApps have monthly active users in the thousands to tens of thousands, and very few can reach a million.

When I registered, I completed an identity verification. After verification, Sign generated an on-chain attestation credential for me. This credential does not exist on Sign's servers; it exists on-chain. Later, for any operation in the ecosystem that requires identity verification, I do not need to resubmit materials; I can directly reference this credential.

This step helped me understand why the label "super app" is only half correct.

Half correct: The Sign App indeed wants to be an entry-level product, integrating identity verification, credential management, and asset viewing in one interface. Users do not need to understand what attestation is or what Schema is; they just click to complete verification, and the backend automatically handles the on-chain operations. Hiding complex technology behind simple interactions is the right approach.

Half incorrect: The core of a super app is usually payments or social interactions. The core of the Sign App is not these; it is identity credentials. It is not about "you use it to spend money" or "you use it to chat"; it is about "you use it to prove who you are." A more accurate positioning should be "Web3's digital ID"—a credential that solves all institutions' verification needs.

This positioning may not be felt in developed countries. I already have an ID card, a passport, and a bank account; having one more Sign App is just an added benefit for me. But what about in Sierra Leone? World Bank data shows: 542 million Africans lack formal identification, only 25.4% of adults in Sierra Leone have mobile payment accounts, and only 3% link mobile payments to banks.

In this environment, the Sign App is not "just another app"; it is the first time many people have a verifiable digital identity. One verification, permanently usable, cross-institutional reference, without relying on any single platform.

Sign has signed a MoU with the Ministry of Communications and Innovation of Sierra Leone, with over 6 million citizens to enter digital registration. It has been deployed in the UAE and Thailand, with plans to expand to over 20 countries.

$SIGN token consumption is tied to the issuance and verification of attestations. Each user registration on the Sign App is an issuance, and each identity verification reference is an on-chain call. 1.5 million monthly active users means at least millions of on-chain operations each month. If it expands to 20 countries and monthly active users reach tens of millions, the consumption scale will be completely different.

I am focused on two things: the registration conversion rate after the Sign App officially launches in Sierra Leone and the 30-day retention of existing users. The first indicates whether those "without ID" are truly willing to use it, and the second shows whether they will continue to use it after trying.
