Program Overview

ApeSwap is a Decentralized Exchange / Automated Market Maker, Yield Farming, and Staking platform running on Binance Smart Chain, with lots of other features that let you earn and win tokens. ApeSwap was built by DeFi Apes, for DeFi Apes. They have a dedicated team of experienced monkeys, who have been in the crypto space for years. BANANA is the native currency of our platform. Stake, pool, and earn $BANANA (along with many other tokens) all on ApeSwap. For more information about ApeSwap, please visit https://apeswap.finance/.

The bug bounty program covers its smart contracts and apps and is focused on the prevention of loss of user funds.

Rewards by Threat Level

Rewards are distributed according to the impact of the vulnerability based on the Immunefi Vulnerability Severity Classification System V2.2. 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 web and app bugs must come with a PoC in order to be accepted. All web and app bug reports without a PoC will be rejected with a request for a PoC.

The reward for critical smart contract vulnerabilities is further capped at 10% of economic damage, taking into account things like funds that are directly at risk.

Payouts are handled by the ApeSwap team directly and are denominated in USD. Payouts are done in BANANA or BUSD, at the discretion of the ApeSwap team.

Assets in scope

Only web/app vulnerabilities that directly affect the web/app assets listed in this table and the subdomain highlighted are accepted within the bug bounty program. All others are out-of-scope.

Other smart contracts in production for ApeSwap not listed in this table may also be considered for the bug bounty program, especially if it affects user funds.

Additionally, the following GitHub repositories are shared for reference as they relate to the assets listed in the table. However, only vulnerabilities that affect the assets in production are considered as in-scope of the bug bounty program.
