In a blog post, Polygon, a protocol for building Ethereum-compatible blockchain networks, has explained the reasoning behind the Dec. 5 hard fork that went live across 90% of network validators by Block #22156660. The cause was due to a vulnerability a hacker used to steal 801,601 MATIC worth $2.04 million at the current exchange rate.

All the while, the network had not disclosed publicly what went on during the silent fix upgrade until recently.

On Dec. 3, the post states, the first white-hat hacker submitted a report of a possible exploit of Immunefi, which hosts Polygon's $2 million bounty program, which was confirmed. Another white hat highlighted another vulnerability on Dec. 4, to which a fix was introduced immediately.

In between, the vulnerability is used to steal MATIC tokens, the first in a series of transfers that removes 801,601 MATIC in total. Still, the fix, a hard fork on Dec. 5, was able to protect a significant trove of funds for Polygon as the vulnerability puts more than 9.27 billion MATIC at risk, which is worth $23.6 billion at press time. This also marks a major chunk of Polygon's total supply of 10 billion.

Polygon stated that it paid a total of about $3.46 million as a bounty to two white hats who helped discover the bug. Polygon's bug bounty program awarded Leon Spacewalker $2.2 million; a different white hat who reported the same bug won nearly $1.26 million.

Polygon (MATIC) price

Polygon (MATIC) is seeing a slight rebound after declines from its $2.92 all-time highs. MATIC suffered rejection after marking record highs at $2.92 on Dec. 27. The downswing extended amid the latest market sell-off, with MATIC shedding nearly 17.8% to lows of $2.40 on Dec. 29. At press time, MATIC was exchanging hands at $2.50, up 0.62% on the day.
