46,210 issuers used Proof of Attendance Protocol to create onchain mementos across the platform's operational life, the company confirmed as it announced a shutdown following more than five years in service. The issuer base included Coinbase and American Express, a pairing that placed the same crypto infrastructure inside a major digital asset exchange and a traditional financial institution. The protocol closes without a stated successor or acquirer.
The issuer count in context
46,210 is the total number of organizations and individuals that created POAP drops over the platform's lifetime. Each issuer generated a mintable token tied to a specific event or moment; users collected those tokens to their wallets as permanent onchain records of attendance. The source does not report a total mint count, so the full scale of user-side activity is unquantified.
Coinbase and American Express are the two named issuers, and they sit at opposite ends of the adoption spectrum. Coinbase runs exchange and custody infrastructure for digital assets. American Express operates in credit and payments, entirely outside crypto's core user base. Both building POAP campaigns suggests the memento model found genuine use cases beyond the web3 audience that incubated it.
The product mechanics
POAP functioned as event-specific token infrastructure. An issuer created a drop associated with a particular moment or action. Users minted the resulting token to prove participation. The source describes the tokens as mementos, framing them as records rather than tradeable instruments.
The shutdown
The platform ran for more than five years before this closure. No reason for the shutdown, no wind-down timeline, and no buyer appear in the source announcement. The 46,210-issuer figure is the last reported measure of the platform's reach before the service ends.
