Wormhole

• Tier 1: Ability to Extract the TVL of all chains: Up to 20,000,000 W
• Tier 2: Ability to Extract the TVL of a single chain: Up to 10,000,000 W
• Tier 3: Ability to permanently deny access to the TVL of one or many chains: Up to 5,000,000 W

All rewards are decided on a case-by-case basis, taking into account the exploitability of the bug, the impact it causes, and the likelihood of the vulnerability presenting itself if it is nondeterministic or some of the conditions are not present at the time. The rewards presented in the payout structure above are the maximum rewards and there are no minimum rewards.

Rewards for critical vulnerabilities are further capped at 10% of extractable value during a 24h period (see Governor mechanism: https://github.com/wormhole-foundation/wormhole/blob/main/whitepapers/0007_governor.md). Rewards for vulnerabilities resulting in the indefinite locking of funds are further capped at 1% of destroyable value. Rewards for critical vulnerabilities relating to NFTs are further capped at 80,000 W.

Value is calculated based on the current market value and available liquidity for widely-used tokens in the Portal Token Bridge, e.g. ETH and SOL.

In cases where the report achieves more than one of the above objectives, rewards will be tiered to the higher of the two objectives and will not be aggregated (eg. if you have the ability to extract and brick a complete TVL for a chain, you will be awarded a bounty as if you were able to only extract the complete TVL for that chain).

Rewards for bugs in dependencies and third party code are at the discretion of the Wormhole team and will be based on the impact demonstrated on Wormhole. If the dependency has its own bug bounty program, your reward for submitting this vulnerability to Wormhole will be lowered by the expected payout of that other program. If the vulnerability is in a connected blockchain itself rather than the Wormhole code, the locked and wrapped assets on that chain are not included in the impact calculation.

Wormhole Foundation will maintain full discretion on the payouts for vulnerabilities. We do encourage bug reporters to submit issues outside of the above-mentioned payout structure, though we want to be clear that we’ll exercise discretion on a case-by-case basis -- whether an issue warrants a payout and what that ultimate payout would be.
