The AI trading system NoFx has sparked equity and open source disputes, with the project party, involved parties, and incubator Amber.ac responding in succession.

On December 22, Tinkle, the developer of the open source AI trading system NoFx, released a statement regarding the community controversy triggered by early project participant Zack. Zack joined the project on October 29, 2025, after its open-source release, participating for only about 14 days and contributing a small amount of code. He then demanded 50% equity in exchange for referring Amber for commercialization. After being rejected, he withheld the project's Twitter account and, through a lawyer's letter, demanded 500,000 USDT while disseminating false information through multiple channels. Tinkle stated that all relevant records are verifiable and that the team will no longer respond to personal disputes, focusing on product development instead. In response, Zack issued a statement rebutting the claims, stating that the allegations are severely misleading and harm his personal reputation. The lawyer's letter was sent by a law firm, and evidence has been secured by the lawyer. His claims are legal and compliant, and if the dispute cannot be resolved through legal channels, complete evidence including videos, audio, chat records, and timelines will be made public. The official NoFx X account subsequently released an open letter stating that recent discussions regarding community members, the boundaries of code use, and intellectual property have been handed over to a professional legal team for unified handling, denying rumors of financing and benefits transfer, and emphasizing that NoFx is a community-driven open source project rather than a commercial company. The team reiterated that the project adopts the AGPL-3.0 license and will legally uphold open source standards and contributor rights. In the future, they will return to the engineering itself and focus on creating an AI Trading OS that supports self-hosting and multi-platform access. Additionally, Amber Group's ecological accelerator amber.ac also released a statement clarifying that, as of now, there is no formal incubation, investment, or commercial cooperation relationship with the NoFx project; both parties have only engaged in open industry exchanges and called on all parties to return to technical and rational communication to promote healthy ecological development.
