Program Overview

Access active liquidity management on Uniswap v3. Gamma has developed a protocol, a management infrastructure, and a variety of strategies used by managers and market makers. As an LP, you can deposit your assets for Gamma to actively manage in Uniswap v3 positions, returning yield in the asset you deposit.

For more information about Gamma, please visit https://www.gammastrategies.org/.

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

  • Loss of user funds
  • Theft of unclaimed yield or principal
  • Freezing of unclaimed yield

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 bug reports must come with a PoC in order to be considered for a reward.

The following known issues would be considered as out-of-scope of this bounty program:

  • For the UniProxy contract, its deposit configuration is its operational context. Attacks which depend on different configuration than provided for their example hypervisor contract are not to be considered
  • For the xGamma contract, an attack is possible wherein the attacker deposits just before and withdraws just after rebase. In our operational context, they do not send funds (rebase) to the xGamma contract outside of private rpc.

Payouts are handled by the Gamma team directly and are denominated in USD. However, payouts are done in either GAMMA, ETH or USDC, up to the discretion of the team.
