Gearbox is a generalized leverage protocol: it allows you to take leverage in one place and then use it across various DeFi protocols and platforms in a composable way. The protocol has two sides to it: passive liquidity providers who earn higher APY by providing liquidity; and active traders, farmers, or even other protocols who can borrow those assets to trade or farm with x4+ leverage.

The core vision is to become a backend composable leverage protocol that all kinds of users have but don’t even need to interact directly with any interface.

About the Bug Bounty Program

This bug bounty program is focused on their smart contracts and is focused on preventing:

  • Thefts and freezing of principal of any amount
  • Thefts and freezing of unclaimed yield of any amount
  • Unexpected sandwiching or manipulation of user trades
  • Incorrect use of oracles or their malfunction
  • Any Cream-style mathematic attack on the protocol work
  • Theft of governance funds

Rewards by Threat Level

Rewards are distributed according to the impact of the vulnerability based on the Immunefi Vulnerability Severity Classification System. This is a simplified 5-level scale, with separate scales for websites/apps and smart contracts/blockchains, encompassing everything from consequence of exploitation to privilege required to likelihood of a successful exploit.

All Smart Contract bug reports require a PoC to be eligible for a reward. A suggestion for a fix is preferred but not compulsory for Low and Medium Smart Contract bug reports. Explanations and statements are not accepted as PoC and code is required.

Critical smart contract vulnerabilities are capped at 10% of economic damage, primarily taking into consideration funds at risk, but also PR and branding aspects, at the discretion of the team. However, there is a minimum reward of $50,000.

All vulnerabilities marked in the are not eligible for a reward.

Payouts are handled by the Gearbox team directly and are denominated in USD. However, payouts are done in USDC.
