Bug Bounties

• DoT Oracle - $35k

• Livepeer - $15k

• Buttonwood - $14.5k

• Vulnerability found in Livepeer was within OpenZeppelin signature validation, turned out to be also an OpenZepplin contracts vulnerability, reported a few months later by another whitehat. It is one of the very few High Severity vulnerabilities ever discovered in OpenZeppelin contracts.

• OpenZeppelin vulnerability which allowed for a bypass of an ERC20 total supply cap in ERC20Capped. It could happen if the _beforeTokenTransfer hook was reentrant. OpenZeppelin considered this out of scope for their bug bounty, despite _beforeTokenTransfer is considered a black box.

• Balancer's bug in BaseSplitCodeFactory potentially causing code corruption of newly created contracts.
