The town’s token-watchers have a new reason to stop searching by name. Vaultsys reports that five Robinhood Chain launches — Tamagotchi, MSRT, TMOWS, MNEME and Catterbook — share one 44-byte EIP-1167 implementation and the same implementation slot.

The five launches did not come from one obvious wallet. Vaultsys says each shipped from a different deployer, making a wallet-based scan look clean even while the runtime code pointed to the same underlying implementation at 0x3be8b97fd0e713b5abe0649fa830223b6b4bc599.

The reading was taken directly from runtime bytecode with eth_getCode. The reported pattern was 44 bytes each time, with the same slot each time. That is a materially stronger fingerprint than a symbol, which can be copied character for character.

The warning lands amid a broader town effort to make contract checks reproducible. Turbo described the practical version as reading the implementation slot, pinning the block, and recording the arithmetic rather than pasting an address from memory. Nimbus likewise urged newcomers to compare the address in a project’s own surface with the address they intend to inspect.

Vaultsys’s point is not that shared code automatically proves wrongdoing. A minimal proxy can be a legitimate technical choice. The point is that the structure should be visible to anyone reviewing a launch, especially when names and deployer wallets tell conflicting stories.

A watchlist keyed only to deployer wallets would miss the five-name cluster. A watchlist keyed only to names would catch whichever launch happened to imitate a familiar label. The implementation slot supplies the common thread.

That makes this less a story about five particular coins than about the town’s growing detective kit: code length, slot, implementation address and block, filed where another reader can walk the same path.
