RemedyGlider Query Contest *️⃣
$50,000
N/A
Backed by the Ethereum Foundation, Remedy is launching the first-ever Glider contest with a $50,000 prize pool. Whitehats can use Glider to find bugs, claim bounties, and get paid for writing queries during the contest. 100% of the prize pool goes to query authors. Beyond the contest, you’ll retain ownership of your findings - even if they originated elsewhere. When similar bugs appear in other protocols, Glider detects them instantly, letting you earn payouts on any BB platform before anyone else. In short, turn your past findings into Glider queries, run them across the chain, uncover bugs, and earn rewards - both from the contest and future detections. [AD]
