Program Overview

Lixir Finance is a concentrated liquidity manager designed to automate liquidity management and optimize returns. Lixir sets out to integrate the next generation of Automated Market Makers (AMMs) that offer the ability to provide liquidity in a tight range, such as Uniswap V3. Concentrated liquidity allows liquidity providers to greatly increase the revenue from

Liquidity Provider fees (LP fees), but there are trade-offs. Lixir is designed to simplify and optimize these trade-offs through a user-friendly interface that hides all the complexity that concentrated liquidity introduces.

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

  • Thefts and freezing of principal of any amount
  • Thefts and freezing of unclaimed yield of any amount
  • Theft of governance funds
  • Governance activity disruption

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 Critical Smart Contract bug reports require a PoC, and a suggestion for a fix for Medium, High and Critical bugs is required to be eligible for a reward.

Critical smart contract vulnerabilities are capped at 15% 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 USD 50 000.

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