Responsible Publication

BankX adheres to category 3: Approval Required. This Policy determines what information whitehats are allowed to make public from their submitted bug reports. For more information about the category selected, please refer to our Responsible Publication page.

BankX adheres to the Primacy of Rules, which means that the whole bug bounty program is run strictly under the terms stated in this page.

Known Issue Assurance

BankX commits to providing Known Issue Assurance to bug submissions through their program. This means that BankX will either disclose known issues publicly or at the very least privately via a self-reported bug submission in order to allow for a more objective and streamlined mediation process to prove that an issue is known. Otherwise, assuming the bug report itself is valid, it would result in the bug report being considered in-scope and due 100% of the reward with respect to the bug bounty program terms.

Rewards by Threat Level

Rewards are distributed according to the impact the vulnerability could otherwise cause based on the Impacts in Scope table further below. In cases of repeatable attacks for smart contract bugs, only the first attack will be counted, regardless of whether the smart contract is upgradable, pausable, or killable.

Previous Audits

BankX has provided these completed audit review reports for reference. Any unfixed vulnerability mentioned in these reports are not eligible for a reward.

Proof of Concept (PoC) Requirements

A PoC is required for the following severity levels:

  • Smart Contact, Critical Severity Level

All PoCs submitted must comply with the Immunefi-wide PoC Guidelines and Rules. Bug report submissions without a PoC when a PoC is required will not be provided with a reward.
