Program Overview

Trader Joe is a leading DEX on Avalanche, Arbitrum and BNB Chain. Its latest version, V2 aka the Liquidity Book, is a novel concentrated liquidity AMM that discretises price into constant sum price bins. In addition, its novel architecture includes a variable fee component based on volatility that is measured from its internal volatility oracle. The uniqueness of this AMM has seen it propel to one of the leading AMMs globally.

For Whitehats: It is highly recommended that you review the details of this program in full. Although many Bug Bounty programs have standard terms and conditions, each also has their own unique details that are critical to your success.

Prior to submitting a report please review the Immunefi Bug Report Template and Best Practices.

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 system with separate scales for Smart Contracts and Websites/Apps.

Payouts and Payout Requirements:

Payouts are handled by the Trader Joe team directly and are denominated in USD. However, payouts are done in USDC. Trader Joe commits to honoring payouts according to the terms set out in this program at the time of report submission, and to treat this program as the agreement and source of truth concerning bug reports and responsible disclosures.

For the purposes of determining report validity, this is a Primacy of Impact program.

Learn more about report validity best practices here: Best Practice - Primacy of Impact vs Primacy of Rules.

KYC Requirements:

Trader Joe does not have a Know Your Customer (KYC) requirement for bug bounty payouts.

Audit Discoveries and Known Issues:

Bug reports covering previously-discovered bugs are not eligible for any reward through the bug bounty program. If a bug report covers a known issue, it may be rejected together with proof of the issue being known before escalation of the bug report via Immunefi.

Assets in scope

Impacts only apply to assets in active use by the project like contracts on mainnet or web/app assets used in production. Any impact that applies to assets not in active use, like test or mock files, are out-of-scope of the bug bounty program unless explicitly mentioned as in-scope.

Smart Contracts

Whitehats are highly encouraged to review any potential subdomains and what specific port(s) are in scope. Even though the domain may be the same, different ports may point to different assets.

Dev Environment and Documentation

Trader Joe has included dev documentation and/or instructions to help in reviewing code and exploring for bugs:

Impacts to other assets

Hackers are encouraged to submit issues outside of the outlined Impacts and Assets in Scope.

If whitehats can demonstrate a critical impact on code in production for an asset not in scope, Trader Joe encourages you to submit your bug report using the “primacy of impact exception” asset.

Impacts in Scope

Prohibited Activities

The following activities are prohibited by this bug bounty program.

Please note that Immunefi has no tolerance for spam/low-quality/incomplete bug reports, “beg bounty” behavior, and misrepresentation of assets and severity. Immunefi exists to protect the global crypto community, not facilitate grift.

  • Attempting phishing or other social engineering attacks against our employees and/or customers
