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, smart contracts, and blockchains/DLTs, focusing on the impact of the vulnerability reported.
All web/app bug reports must come with a PoC with an end-effect impacting an asset-in-scope in order to be considered for a reward. Critical and High Smart Contract bug reports require a PoC to be eligible for a reward. Explanations and statements are not accepted as PoC and code is required.
Critical smart contract vulnerabilities are capped at 10% 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 20 000. High smart contract vulnerabilities are capped at 10% of economic damage as well, with a minimum reward of USD 10 000.
Hyperlane requires KYC to be done for all bug bounty hunters submitting a report and wanting a reward. The information needed are Name and Identity Proof (Passport, / Driving License / National ID). The collection of this information will be done by the project team.
Payouts are handled by the Hyperlane team directly and are denominated in USD. However, payouts are done in USDC.

All smart contracts of Hyperlane can be found at https://github.com/hyperlane-xyz. However, only those in the Assets in Scope table are considered as in-scope of the bug bounty program.
Though only the proxy contracts are listed as in-scope, current implementation and any further updates to the implementation contracts are considered in scope. When reporting a bug, please make sure to select the relevant proxy smart contract as the target.
If an impact can be caused to any other asset managed by Hyperlane that isn’t on this table but for which the impact is in the Impacts in Scope section below, you are encouraged to submit it for the consideration by the project. The vulnerability will then be evaluated by Hyperlane core contributors in good faith to determine where it would lie on the vulnerability scale.
