A pseudonymous trader says their group pocketed more than $6 million by buying two Robinhood Chain memecoins before Robinhood listed them. The claimed edge was not a leaked memo or a friend on the inside. It was public data: a code change at BitGo and the onchain footprints of market maker Wintermute.
The trader posts on X as @3i. Their write-up has pulled in more than 300,000 views.
How the trade supposedly worked
The two tokens at the center of the claim are CASHCAT and PONS. Both trade on Robinhood Chain, and both later landed on Robinhood’s listing roster.
According to @3i, the group spotted a public change in BitGo’s code that pointed toward the upcoming listings. They paired that with an analysis of Wintermute’s onchain flows, which they read as further confirmation that something was coming.
The account was published on Saturday. The Block, which reported on the claims, said it confirmed several of the public records @3i cites. It also found wallet activity that lines up with parts of the trader’s timeline.
There is a significant caveat. The Block could not verify the profit figures. The $6 million number comes from @3i alone, and it should be treated as a self-reported claim until someone shows the receipts in full.
Cash Cat’s short, loud history
CASHCAT emerged as the flagship memecoin on Robinhood Chain shortly after the network’s mainnet launch on July 1, 2026. It climbed fast, reaching peak market caps above $100 million.

The early rally minted some eye-catching wallets. Multiple addresses reportedly turned entries of under $1,000 into gains of more than $1 million during the July 2026 surge.
Robinhood Chain is built as an Arbitrum Orbit chain, designed for tokenized real-world assets, meaning traditional financial instruments represented onchain. Memecoins have captured most of the chain’s initial trading volume and engagement.
Fast-money tactics have shown up on the chain before. Between September 12 and 25, 2026, bot groups extracted $62,000 from $6.5 million in targeted trades.
Public signals, private advantage
The story sits in an awkward gray zone. Nothing @3i describes involves secret information, at least by their own account. The BitGo change was public, and Wintermute’s activity happened on a public blockchain.
Yet very few people had the tools, time, or instinct to connect those dots. Blockchains are transparent, but transparency only helps people who know where to look.
For infrastructure providers and market makers, the episode is a reminder that operational footprints can leak intent. A code commit or a wallet transfer can say more than a press release.
What to watch next
The first open question is verification. The Block matched parts of the timeline but not the profits. If @3i or independent onchain sleuths publish fuller wallet trails, the $6 million claim will either firm up or fall apart.
The second is copycats. A write-up with more than 300,000 views is effectively a playbook. More traders will likely start monitoring infrastructure code repositories and market maker wallets for the next listing hint.
