Proof of Attendance Protocol (POAP) is shutting down after 5+ years of operation as a widely-used onchain attestation platform.
Tech & Launches ·
Proof of Attendance Protocol (POAP), an onchain attestation platform that accumulated over 46,210 issuers including Coinbase and American Express, is shutting down after more than five years of operation. The platform enabled these organizations to create and distribute onchain mementos that users could mint, establishing a widely-used standard for recording event attendance and participation as verifiable digital records.
The shutdown marks the end of a significant infrastructure layer in the onchain ecosystem. POAP had become embedded across major brands and enterprises seeking to tokenize proof of attendance, though the reasons driving the decision to cease operations have not been detailed in available reporting.
What remains unclear is the operational status of existing POAP records and whether issued mementos will remain accessible on-chain, as well as whether any successor service or migration path for current issuers has been announced.
