Compound, once a leading decentralized lending protocol, has seen its Total Value Locked (TVL) plummet from a peak of $12 billion in November 2021 to approximately $1.4 billion. A critical bug in an update in 2021 led to an overpayment of tens of millions of dollars in COMP tokens, severely impacting user confidence. This bug, combined with the onset of the crypto bear market and leadership changes, further eroded Compound's market dominance. Currently, Compound ranks seventh among DeFi lending platforms by TVL, trailing significantly behind Aave, which has a TVL of nearly $27 billion. Its monthly fees have also dropped substantially from a high of nearly $47 million in 2021 to around $3.5 million.
