Techub News reports that Isabel, co-founder of digital collectibles protocol POAP, has announced that the platform will enter maintenance mode starting March 16. New issuers will no longer have access to the issuance interface; existing issuers can continue using their current tools, and already created POAPs remain unchanged; this change will not affect the collector interface, APIs and existing integrations will continue to operate; the platform will cease active development, and some operations may run slower due to resource reduction.
