Ross Ulbricht’s wallet is losing millions on Pump Fun memecoins

Protos reports that a Solana wallet linked to pardoned Silk Road founder Ross Ulbricht has incurred roughly $12 million in losses while interacting with a fan-created memecoin called ROSS on the Pump.fun launchpad platform. According to blockchain analytics firm Arkham Intelligence, a developer launched the ROSS token as a donation vehicle for Ulbricht and sent him 50% of the total supply, worth tens of millions of dollars at peak prices. Instead of simply holding or selling the allocation over-the-counter, the wallet’s controller attempted to set up on-chain liquidity in order to sell the tokens gradually, but made serious configuration errors that left the position exposed to Maximal Extractable Value (MEV) bots. Arkham’s analysis shows that the address first tried to add single-sided liquidity for a small portion of the ROSS supply on Solana DEX Raydium, but initialized a constant-product market maker (CPMM) pool at an incorrect price rather than using Raydium’s concentrated liquidity (CLMM) interface. This mispricing allowed an MEV bot to buy the tokens at a deep discount and immediately dump them back into the pool, crashing the ROSS price and realizing a seven-figure profit at the wallet’s expense. Less than an hour later, a similar mistake was repeated with a much larger share of the supply, amplifying the losses to around $12 million and wiping out more than 85–90% of the token’s value. The episode underscores how complex liquidity tooling, automated bots, and thinly traded memecoins on Solana can expose even high-profile users to outsized, irreversible losses when they misconfigure pools or misjudge on-chain market mechanics. At the time of reporting, blockchain data indicates that the Ulbricht-linked address still holds a smaller remaining portion of the ROSS supply in a correctly configured Raydium CLMM pool, now worth only a fraction of its earlier valuation—on the order of hundreds of thousands of dollars instead of the prior eight-figure sum. Ulbricht has not publicly commented on the trades, leaving open the question of whether he personally executed the transactions or whether another party with access to the wallet controls the keys. For Pump.fun and the broader Solana memecoin ecosystem, the incident highlights ongoing concerns about speculative token launches, user sophistication around DEX liquidity management, and the role of MEV bots in extracting value from mispriced on-chain activity.
