Polymarket has launched a $5 million bug bounty on Cantina, betting that outside hackers can help it harden the code.
Prediction market platform Polymarket is offering up to $5 million to security researchers who can find serious bugs in its system, running the program through Cantina, a platform that connects crypto projects with outside security experts.
In an X post on Monday, April 13, Cantina wrote that the bounty covers almost everything behind the app, including:
- the smart contracts that handle settlement;
- the collateral system that holds user funds;
- the oracle connections that feed in real-world data;
- and the web app people actually use.
Polymarket Unveils Bug Bounty as Fees Surge
Top rewards go up to $5 million for critical issues in the core contracts, and up to $250,000 for major web vulnerabilities, the post reads.
The bug bounty launch comes as Polymarket is going through a period of fast growth. It recently rolled out fees across most market categories, a change that helped lift daily revenue above $1 million.

According to data from DefiLlama, Polymarket generated over $11 million in fees earlier in March.
At the same time, Polymarket is moving closer to mainstream finance. Earlier in April, the prediction market platform added support for Pyth Network, giving retail traders a way to bet on gold, silver, oil, and more than a dozen U.S. stocks.
