ai16z co-founder Shaw said code he previously posted in the GitHub repository lalalune/pumpfun-source was not open source. In a post on X, he said the code did not belong to him and that he had never had the right to publish it, license it or authorize others to use it.
Shaw said license notices in the repository, including “Copyright (c) 2026 Shaw,” were invalid and granted no rights. He warned users not to rely on those notices or his earlier statements as permission to use, copy, fork, modify, build upon or distribute the code. He also said the pump.fun code is protected by copyright and should not be distributed or reverse-engineered.
Foresight News reported that Bracket Company Inc., Pump.fun’s parent company, had sent Shaw a cease-and-desist letter through law firm Brown Rudnick on October 29. At the time of the report, the original repository had been deleted or made private. The report did not establish which of those had occurred or why.
