A GitHub repository containing pump.fun code should not be treated as an open-source release, according to Shaw, an ai16z co-founder.
As reported by Foresight News on November 12, 2026, at 15:51 (UTC+8), Shaw said the code he had previously posted to lalalune/pumpfun-source did not belong to him and that he had never had the authority to publish it, license it, or authorize anyone else to use it. He said the repository’s license text, including “Copyright (c) 2026 Shaw,” was invalid and granted no rights.
What this means for developers: Shaw warned readers not to rely on that license or his earlier statements as permission to use, copy, fork, modify, build on, or distribute the code. He also said pump.fun’s code is copyright-protected and should not be distributed or reverse-engineered.
Foresight News noted that Bracket Company Inc., pump.fun’s parent-company entity, had sent Shaw a cease-and-desist letter through Brown Rudnick on October 29. At the time of the report, the original repository had been deleted or made private.
