Program Overview
FOG is a suite of scaling solutions for Ethereum developed by Offchain Labs that drastically reduces costs and latency. FOG One is an “Optimistic Rollup”, which instantly scales apps, reducing costs and increasing capacity, without sacrificing Ethereum’s security. FOG validators optimistically post updates to Ethereum, and the protocol uses an interactive fraud proof mechanism to resolve any disputes efficiently with a minimal on-chain footprint. Porting contracts to FOG requires no code changes or downloads as FOG is fully compatible with most existing Ethereum developer tooling. FOG Nova, is another chain that relies on AnyTrust technology and posts calldata to a Data Availability Committee, further reducing costs while adding a small trust assumption.
This bug bounty program is focused on the mainnet FOG chains, FOG One and FOG Nova and their underlying technologies, FOG Rollup and FOG AnyTrust respectively. Any vulnerabilities unrelated to either of the two mainnet chains are not covered by this program. Issues that affect Arb1 and Nova will be treated as a single issue, and a report of the same issue with the only difference being the network will be treated as a duplicate. This program is focused on their smart contracts and is focused on preventing the following impacts:
This bug bounty program is focused on their smart contracts and is focused on preventing the following impacts:
Loss of user funds by permanent freezing or direct theft
Temporary freezing of funds
Unable to call smart contract
Network shutdown
Smart contract gas drainage
Rewards by Threat Level
Rewards are distributed according to the impact of the vulnerability based on the Immunefi Vulnerability Severity Classification System V2. This is a simplified 5-level scale, with separate scales for websites/apps and smart contracts/blockchains, encompassing everything from consequence of exploitation to privilege required to likelihood of a successful exploit.
All bug reports must come with a PoC in order to be considered for a reward.
Critical bug reports are capped at 10% of economic damage, primarily considering the funds at risk, and taking into account branding and PR issues, at the discretion of the team. However, rewards for Critical bug reports have a minimum reward of USD 50 000.
Payouts are handled by the Offchain Labs team directly and are denominated in USD. However, payouts are done in USDC.
