What is The Dogestar (SIRIUS)? New Meme Coin on Robinhood Chain

The trending token leaderboard on Robinhood Chain changes rapidly every hour, and towards the end of August 2026, a new name sneaked into the list: SIRIUS, which carries the alias The Dogestar. 

Not even a full day since its liquidity pool was opened, this token has already recorded thousands of percent price surges as well as sharp corrections within just hours — a movement pattern that has left many traders curious about what The Dogestar actually is, and why the name SIRIUS crypto suddenly became a hot topic on the X timeline.

This article reviews the token's origins, the narrative claims behind it that drag in the name of Robinhood's CEO, the latest on-chain data, and the context of the memecoin trend that is spreading on Robinhood Chain.

Key Takeaways

• The Dogestar (SIRIUS) is a new meme coin on Robinhood Chain, paired with USDG on Uniswap V4, with a liquidity pool that is only a few hours old at the time of monitoring.
• Its main narrative links the token to a past statement by Robinhood CEO Vlad Tenev about the star Sirius in 2021 — however, these claims come from the project's anonymous team, not an official confirmation from Robinhood.
• The token's price is highly volatile, having surged thousands of percent in 24 hours but also corrected sharply within hours, reflecting the high risk typical of newly launched meme coins.

What is The Dogestar (SIRIUS) on Robinhood Chain?

SIRIUS is a newly launched meme coin on Robinhood Chain, an Ethereum-based Layer 2 blockchain built by Robinhood using Arbitrum Orbit technology. The token is traded in the SIRIUS/USDG pair on Uniswap V4, with a liquidity pool that was created about 13 hours before the data for this article was taken from DexScreener. 

Total liquidity is around $102 thousand, while the market cap and fully diluted valuation (FDV) are in the range of $1.5 to $1.7 million — figures that are relatively tiny and prone to drastic changes with just a few large transactions.

As a newborn token, SIRIUS does not yet have a whitepaper or official roadmap like typical crypto projects. The team behind it is also anonymous, which is common among the new generation of meme coins that rely on virality rather than technical fundamentals.

Where Does the Name "The Dogestar" Come From? The Claims About Vlad Tenev

The most interesting yet cautious part of this token is the narrative behind it. The project's official X account, @DogestarOnRH, claims that in 2021, Robinhood CEO Vlad Tenev once referred to the star Sirius with the nickname "Dogestar". 

Armed with that claim, the team behind the token registered a star through the Staracle service and dedicated it with the name "The Dogestar" on August 30, 2026 — right before the token's launch — as what they call "proof" of the connection to Vlad Tenev's statement.

It is important to emphasize: Staracle is a commercial symbolic gift service that allows anyone to name a star from an astronomical catalog for about $5. 

Such naming is not scientifically recognized by any official astronomical body, and the certificate is by no means a form of endorsement or involvement from Robinhood or Vlad Tenev directly. 

As of this writing, there has been no official confirmation from Robinhood regarding the claim. This pattern of building narratives from old references to public figures is quite common in the meme coin world — its purpose is to attract attention and liquidity, not to indicate actual affiliation.

On-Chain Data: Extreme SIRIUS Volatility in a Matter of Hours

SIRIUS price movement clearly illustrates how wild a newborn meme coin can be. Within a 24-hour range, its price surged over 4,300%, but in the last hour before the data was taken, it had corrected more than 20%. 

24-hour trading volume was recorded at around $5.3 million with more than 3,600 traders involved, indicating very active buying and selling activity for a token of such a young age.

From a contract security perspective, Go+ Security scan results for this token are not yet available ("Not available"), while Quick Intel marks "No issues" — although accompanied by a standard warning that such automated scan results are not always 100% accurate. 

The combination of thin liquidity, an anonymous team, and a very young token age puts SIRIUS in the high-risk asset category, far different from well-established and thoroughly audited crypto assets.

Robinhood Chain and the Memecoin Season: The Broader Context

SIRIUS is not a standalone phenomenon. Robinhood Chain was actually launched on July 1, 2026, with the official mission of becoming an on-chain rail for tokenized stocks and real-world assets. 

However, according to a CoinDesk report, since its early weeks, the network has been dominated by memecoin trading — not tokenized assets as originally promoted. One example is CASHCAT, a meme-themed cat token that once contributed tens of millions of dollars in daily volume on the network.

This phenomenon has led many to call it a "memecoin season" on Robinhood Chain, similar to the pattern that occurred when Coinbase launched the Base network in 2023 — where speculation and meme coins flooded the new network first, before more substantial applications followed later. 

SIRIUS, with its unique "Dogestar" narrative, essentially follows the same pattern: leveraging the momentum of a new ecosystem to attract traders hunting for short-term opportunities.

Conclusion

The Dogestar (SIRIUS) is a prime example of how creative narratives can drive extreme volatility in the still-young meme coin ecosystem like Robinhood Chain. The claim of its connection to Vlad Tenev attracts attention, but so far it remains a one-sided narrative from the project's anonymous team, not a fact confirmed by Robinhood. 

Coupled with thin liquidity, a token age measured in hours, and price movements that can change drastically in a short time, SIRIUS clearly falls into the category of a highly speculative, very high-risk asset that should be approached with independent research and full caution.
