Omni Network

Omni is the abstraction layer for the Ethereum ecosystem, allowing developers to access all the users and liquidity across rollups without upgrading their contracts. With Omni, using Ethereum and all its rollup feels like a singular chain — no bridging, switching RPCs, or gas management. Omni achieves this through coordinating a network of solvers who handle all cross platform complexities.

Critical Reward Calculation

Reward amount is 10% of the funds directly affected, capped at the maximum critical reward of:

$500,000

Minimum reward to discourage security researchers from withholding a bug report:

$25,000
The reward is dependent on the ratio between the funds at risk, which includes all affected projects on top of the respective blockchain/DLT, and the market cap according to the average between CoinMarketCap.com and CoinGecko.com, calculated at the time the bug report is submitted.

For critical Blockchain/DLT bugs, the reward amount is 10% of the funds directly affected, capped at the maximum critical reward [$500K]. However, a minimum reward of USD [$50,000] is to be rewarded in order to incentivize security researchers against withholding on a bug report.

For critical Blockchain/DLT bugs with a non-funds-at risk impact, the reward will be paid out as follows:

  • Network not being able to confirm new transactions (total network shutdown) - [$50,000]
  • Unintended permanent chain split requiring hard fork (network partition requiring hard fork) - [$50,000]
  • Permanent freezing of funds (fix requires hardfork) - [10% of the funds at risk or $50,000, whichever is lower]

For high Blockchain/DLT non-funds-at risk impacts, the reward will be paid out as follows:

  • Unintended chain split (network partition) - [$25,000]
  • Temporary freezing of network transactions by delaying one block by 500% or more of the average block time of the preceding 24 hours beyond standard difficulty adjustments - [$25,000]
  • Causing network processing nodes to process transactions from the mempool beyond set parameters - [$15,000]
  • RPC API crash affecting projects with greater than or equal to 25% of the market capitalization on top of the respective layer - [$15,000]

For critical smart contract bugs, the reward amount is 10% of the funds directly affected up to a maximum of USD [$500,000]. The calculation of the amount of funds at risk is based on the time and date the bug report is submitted. However, a minimum reward of USD [$25,000] is to be rewarded in order to incentivize security researchers against withholding a critical bug report.

Repeatable Attack Limitations

If the smart contract where the vulnerability exists can be upgraded or paused, only the initial attack will be considered for a reward. This is because the project can mitigate the risk of further exploitation by upgrading or pausing the component where the vulnerability exists. The reward amount will depend on the severity of the impact and the funds at risk.

For critical repeatable attacks on smart contracts that cannot be upgraded or paused, the project will consider the cumulative impact of the repeatable attacks for a reward. This is because the project cannot prevent the attacker from repeatedly exploiting the vulnerability until all funds are drained and/or other irreversible damage is done. Therefore, this warrants a reward equivalent to 10% of funds at risk, capped at the maximum critical reward.

Reward Calculation for High Level Reports

High vulnerabilities concerning theft/permanent freezing of unclaimed yield/royalties are rewarded within a range of [$5,000] to [$25,000] depending on the funds at risk, capped at the maximum high reward.

In the event of temporary freezing, the reward doubles from the full frozen value for every additional [24h] that the funds are temporarily frozen, up until a max cap of the high reward. This is because as the duration of the freezing lengthens, the potential for greater damage and subsequent reputational harm intensifies. Thus, by increasing the reward proportionally with the frozen duration, the project ensures stronger incentives for bug disclosure of this nature.

For critical web/apps bug reports will be rewarded with [$50,000], only if the impact leads to: A loss of funds involving an attack that does not require any user action Private key or private key generation leakage leading to unauthorized access to user funds

All other impacts that would be classified as Critical would be rewarded a flat amount of [$25,000]. The rest of the severity levels are paid out according to the Impact in Scope table.

Program Overview

Omni is the abstraction layer for the Ethereum ecosystem, allowing developers to access all the users and liquidity across rollups without upgrading their contracts. With Omni, using Ethereum and all its rollup feels like a singular chain — no bridging, switching RPCs, or gas management. Omni achieves this through coordinating a network of solvers who handle all cross platform complexities.

Omni’s V1 release in scope for this competition consists of 2 primary building blocks: xchain messaging and the Omni EVM. These building blocks are supported by 3 components that make up the Omni’s core network architecture:

  • Smart contracts on supported chains
  • Cosmos sdk client (halo) which acts as our consensus client for xchain messaging and for the EVM
  • Vanilla geth as the EVM execution client

Responsible Publication

Category 2: Notice Required

Prohibited Activities

Default prohibited activities
  • Any testing on mainnet or public testnet deployed code; all testing should be done on local-forks of either public testnet or mainnet
  • Any testing with pricing oracles or third-party smart contracts
  • Attempting phishing or other social engineering attacks against our employees and/or customers
  • Any testing with third-party systems and applications (e.g. browser extensions) as well as websites (e.g. SSO providers, advertising networks)
  • Any denial of service attacks that are executed against project assets
  • Automated testing of services that generates significant amounts of traffic
  • Public disclosure of an unpatched vulnerability in an embargoed bounty
  • Any other actions prohibited by the Immunefi Rules

Feasibility Limitations

The project may be receiving reports that are valid (the bug and attack vector are real) and cite assets and impacts that are in scope, but there may be obstacles or barriers to executing the attack in the real world. In other words, there is a question about how feasible the attack really is. Conversely, there may also be mitigation measures that projects can take to prevent the impact of the bug, which are not feasible or would require unconventional action and hence, should not be used as reasons for downgrading a bug's severity.

Therefore, Immunefi has developed a set of feasibility limitation standards which by default states what security researchers, as well as projects, can or cannot cite when reviewing a bug report.
