Compound supply bug mistakenly rewarded users with $70M in tokens

Decentralized finance (DeFi) interest rate protocol Compound Finance has reported a token distribution bug within their newly-implemented Proposal 062 which is over-rewarding suppliers into the tens of millions of dollars.

The upgrade was designed to “split COMP rewards distribution and bug fixes,” and was fully verified without issues. However, within hours the team noted "unusual activity,” stating that “Compound Labs and members of the community are investigating discrepancies in the COMP distribution.”

Despite the developments, the team have stressed that no funds either supplied or borrowed are at risk. Users of the protocol are reporting sizable windfalls, one claiming a deposit of 70 million COMP tokens into their account, equivalent to $20 million.

Super-Coder at SushiSwap Mudit Gupta revealed that a single letter bug was responsible for the error in a series of tweets.

About 240k COMP tokens (~$70m) have been given away already and another 40k (~$13m) will likely be given away soon. If you had supplied tokens before today, go try your luck.It will be interesting to see if Compound requests users to return the extra tokens (like Alchemix did)— Mudit Gupta (@Mudit__Gupta) September 30, 2021

This is a developing story and we will update soon.
