Shanghai Solana event halted over alleged unauthorized promotion

Chinese authorities halted the Solana Accelerate event in Shanghai over alleged unauthorized promotional activity, China’s state-backed Financial News reported on Friday.

The outlet cited an unidentified official from a department of the People’s Bank of China (PBOC). The official said domestic entities promoted Solana’s brand through advertisements placed on a building in Shanghai’s Lujiazui financial district.

The same official made a broader allegation, claiming that Solana provides technical services supporting cryptocurrency issuance and trading, conduct he described as illegal financial activities under Chinese regulations. The report did not name the domestic entities or identify the PBOC department.

Why was the Shanghai event halted?

The PBOC and several other agencies had set out their broader crypto stance in a February notice. It reaffirmed crypto-related restrictions and added a ban on unauthorized issuance of yuan-pegged stablecoins.

The action reached beyond digital-asset trading. It targeted how domestic entities advertised Solana and the technical services officials attributed to the project. For a blockchain project, that changes the practical compliance burden: organizers cannot treat local advertising as separate from broader regulatory questions attached to the project’s technical services.

Shanghai was not the first reported disruption of a Solana event in mainland China, following an October 2025 gathering in Shenzhen that ended early because of venue capacity and public-safety concerns. According to an X announcement by Solana’s Chinese-speaking community, the Shenzhen event was cut short for those reasons.

The Financial News report therefore described Shanghai as the second reported disruption of a Solana event in the past two years, extending scrutiny from digital-asset trading into promotion and event operations. That range matters because organizers face venue rules, crowd limits and financial regulation at the same time.

In an Oct. 16 post on X, Solana Foundation president Lily Liu said organizers postponed the Shanghai event “to comply with local requirements” after registration unexpectedly quadrupled and exceeded the cap pre-registered with local authorities.

Her explanation centered on crowd management. The PBOC-linked account focused on alleged unauthorized promotion and technical support for cryptocurrency issuance and trading. The accounts describe different pressure points, but both put the event’s local compliance duties at the center of the decision to postpone it.

What does this change for event organizers?

For organizers, the immediate requirement is procedural: stay within the capacity disclosed to local authorities, meet local event conditions, and ensure brand promotion does not run afoul of restrictions tied to crypto issuance or trading.

The source reported no new date, financial penalty or formal charge against Solana. Nor did it define a deadline for resolving the allegations or approving a replacement event.

The distinction between the two accounts also limits what can be concluded. The Financial News report attributes the building advertising to domestic entities, not directly to Solana. Liu’s post, as quoted, addresses postponement and registration rather than the PBOC-linked allegations. That leaves separate questions about venue capacity, local marketing and the project’s technical role in digital-asset issuance and trading.

Chinese authorities have shown they can intervene before a crypto event proceeds. The next enforcement window comes with the event’s rescheduling, when organizers must address registration limits and local promotional rules before it can move ahead.
