Program Overview

Godwoken Game+ Blockchain is a 100% EVM compatible L2 optimistic rollup on the secure L1 Nervos Blockchain. For more information about Godwoken, please visit https://www.godwoken.com/.

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 Smart Contracts bug reports must come with a PoC with an end-effect impacting an asset-in-scope in order to be considered 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 or the maximum cap, 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 50 000.

Payouts are handled by the Godwoken team directly and are denominated in USD. However, payouts are done in USDC.

Assets in scope

All smart contracts of Godwoken can be found at https://github.com/godwokenrises. However, only those in the Assets in Scope table are considered as in-scope of the bug bounty program.

Note: CKB is an UTXO based blockchain. It doesn't have an address for a smart contract. Users can find more deployment information https://github.com/godwokenrises/godwoken-info/blob/main/mainnet_v1/scripts-deploy-result.json.

If an impact can be caused to any other asset managed by Godwoken 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. This only applies to Critical impacts.
