For more information about LatteSwap, please visit This bug bounty program is focused on their smart contracts and is focused on preventing the following impacts:

  • Thefts and freezing of principal of any amount
  • Thefts and freezing of unclaimed yield of any amount
  • Reentrancy
  • Denial of Service by puting contracts in unforeseeable state

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.

A PoC is required for all bug reports.

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

Smart Contracts and Blockchain

USD $50,000
USD $15,000
USD $5,000
