Boba Network
Submit a BugProgram Overview
Boba Network is a blockchain Layer-2 scaling solution and Hybrid Compute platform offering lightning fast transactions and fees up to 100x less than Layer-1.
Boba Network’s Hybrid Compute technology brings the power of Web2 on-chain for the first time, allowing smart contracts to call any external Web2 API to execute complex algorithms such as machine learning classifiers, pull in real-world or enterprise data in a single atomic transaction, or sync with the latest state of a gaming engine. Leveraging off-chain compute and real-world data, developers and creators can offer an enriched experience unlike anything else on the market today.
Boba Network is delivering a faster, cheaper, and smarter experience for blockchain’s next billion users.
For more information about Boba Network, please visit https://boba.network/.
For testing any exploits involving cross-domain transactions, it is recommended to work with Boba’s dockerized services (https://github.com/bobanetwork/boba/blob/de21c96e0632c2e54927acbb54479c85508bec07/.circleci/config.yml#L14-L19) and modifying integration tests (https://github.com/bobanetwork/boba/blob/25450b4024b0ac6c1789cc55b6dc15675200ed9b/integration-tests/test/bridged-tokens.spec.ts).
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. All High and Critical Blockchain/DLT/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 blockchain/DLT 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 10 000.
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 10 000.
The following vulnerabilities are not eligible for a reward:
- Contracts are upgradable.
- The fact that fraud proofs are not yet running.
- A bug in Lib_MerkleTrie.sol which will prevent withdrawals from succeeding in some cases. There is a workaround for this, by modifying the proof to add an extra element.
- A bug in Lib_ResolvedDelegateProxy.sol which could result in a storage slot key collision overwriting the address of the implementation. This bug is dependent on the layout of the implementation contract, and Boba is not affected.
- The user cannot commit to a L1 gas price, the OVM_GasPriceOracle is owned by a key controlled by Boba and is responsible for setting the L1 gas price.
- There appears to be an obvious bug which would allow an attacker to withdraw a fake ERC20 token from L2 in exchange for a real ERC20 (such as WBTC) token on L1. There is no check in the L2StandardBridge, however the withdrawal is prevented from finalizing by a check in the L1StandardBridge. Naturally if you do find a way to circumvent Boba Network’s protections, then you would be rewarded.
- All vulnerabilities mentioned in https://github.com/bobanetwork/boba/tree/develop/boba_audits
Boba Network requires KYC to be done for all bug bounty hunters submitting a report and wanting a reward for critical and high threat levels. The information needed is proof of your identity. The collection of this information will be done by the Boba Foundation.
Payouts are handled by the Boba Foundation and are denominated in USD. However, payouts are done in USDC.

All smart contracts of Boba Network can be found at https://github.com/bobanetwork. 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 Boba Network 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 and High impacts.
