Program Overview

Charm’s Alpha Vaults creates permissionless vaults to manage Uniswap liquidity. It uses Charm’s expertise in Decentralized Market Making Strategies to help anyone increase the liquidity of any Uniswap V3 pool. Using the vault, anyone can launch liquidity mining campaigns just like Uniswap V2, have full control over the vault’s strategy, increase token liquidity using concentrated liquidity, guarantee tokens will always be tradable, and achieve full decentralization. In addition, the vault’s shares are tokenized and ERC-20 compliant, which means LPs can deposit, withdraw, earn yield, and stake just like regular tokens.

The core contracts of Alpha Vaults version 2 are included within the scope of this bug bounty program.

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.

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