A Fantom wallet check reviews an FTM address for exposure to the collapsed yield farms and Multichain-bridge contamination in Fantom's history; Plastron's live screening currently covers seven other EVM chains, not Fantom.

Fantom experienced one of the most dramatic boom-bust cycles in DeFi history. At its peak, the chain hosted billions in TVL across protocols like SpookySwap, Solidly, and Tomb Finance. Then came the collapses. Tomb Finance's algorithmic stablecoin death spiral, the Multichain bridge catastrophe, and a series of yield farm rug pulls wiped out hundreds of millions in user funds. The wallets that participated in these protocols — even those that exited before the collapses — carry those interactions in their transaction history permanently. The Multichain bridge incident was particularly devastating for Fantom. As the primary bridge connecting Fantom to Ethereum, Multichain's compromise effectively stranded assets on the chain and created a massive contamination event. Wallets that had bridged through Multichain are connected to the exploit fund flows, and compliance tools trace these connections when you eventually move funds to an exchange. Fantom's transition to Sonic adds another layer of complexity. The migration between chains creates new bridge interactions, and the mapping between old FTM addresses and new Sonic addresses needs to be tracked for continuous risk assessment. If your Fantom wallet had risk exposure, migrating to Sonic does not reset your history — the provenance follows.
