Function FBTC earns a C- for its innovative but still-permissioned TSS custody model, meaningful admin centralization risks flagged by security tools, and extreme supply concentration. The $789M TVL with near-zero daily volume creates an acute illiquidity paradox. Suitable for large institutions only; retail users should avoid direct FBTC exposure until admin key risks are mitigated by timelocks and broader Security Council membership.
Risk Breakdown
Top Risks
Centralized admin keys allow contract owner to pause mints/burns, modify fees, and mint tokens arbitrarily — GoPlus flagged these as material risks
Custodial BTC held by Cobo/Antalpha/Mantle TSS nodes: if the 3-of-3 Security Council is compromised or colluded, the entire $789M in BTC backing could be at risk
Extreme whale concentration: only ~11,000 FBTC tokens in circulation with near-zero daily trading volume, creating acute illiquidity and price manipulation risk
