China's Central Bank Opens Probe Into Solana's Shanghai Ad Blitz, Halts Promotional Events - BigGo Finance

China's central bank has opened an investigation into a promotional campaign for Solana in Shanghai and has halted the related events, according to BigGo Finance. The reported scrutiny centers on advertising activity tied to a public blockchain network in a jurisdiction where crypto-related promotion and trading face strict limits.

The development matters for several reasons. It signals that Chinese authorities are monitoring how overseas blockchain projects market themselves to mainland audiences, even when the activity is framed as community or brand promotion rather than exchange trading. For market participants, the probe is a reminder that regulatory risk in China can surface through advertising and events, not only through exchanges or token issuance. It also illustrates the broader gap between global crypto marketing and local compliance rules.

What to watch: whether the review remains limited to promotional activity or widens to other events and sponsorships, and whether similar campaigns by other projects draw attention. Any formal findings, guidance, or enforcement detail from authorities would clarify how strictly promotion is being policed. Until then, the episode is best read as a caution about regulatory exposure in major markets rather than a verdict on the underlying network.
