Join The Bounty Hunt
There are 3 targets to scope:
- Blockchain/DLT
- Smart Contract
- Web & Mobile
Make sure your reports contain info about these incidents:
- Invalid state transition accepted as valid / consensus safety failure
- Bitcoin-anchoring verification failure
- Batch Proof break / bypass
- Light Client Proof split / inconsistent verification
- Reorg-handling bug (Bitcoin-side or Citrea-side) causing prolonged halt, inconsistent views, or unsafe rollback behavior
- Direct theft of user funds (including BTC/cBTC) via deposit/withdraw/verification bugs
- Direct loss of user funds (at-rest or in-motion)
- Permanent freezing of funds (including bridged funds/assets/messages) due to logic bugs (fixable by upgrade or not)
- Temporary freezing of funds
- Protocol insolvency
- Total network shutdown / critical components unable to operate (system smart contracts, sequencer, full nodes)
- Role-based access control / pausing logic vulnerabilities
- Unbounded gas/resource consumption causing severe degradation or halting of critical components (even without theft)
- Theft of gas
- Block stuffing for profit / griefing
- Large-scale griefing disrupting deposits/withdrawals (with no theft other than by the Aggregator)
- Bugs in layer 0/1/2 network code resulting in unintended smart contract behavior without direct funds at risk
- Clementine CLI bugs causing wallet loss, incorrect deposit address generation, or withdrawal losses
- Clementine presigning bugs causing operator reimbursement failures
- Clementine Tx Sender failures
- Retrieve sensitive data/files from a running server
- Taking down the application/website
- Taking state-modifying authenticated actions on behalf of other users without their interaction
- Wallet-drain class UI compromise / malicious interactions with an already-connected wallet
- Injecting or modifying static content on the target application (persistent)
- Misrepresentation of transaction data in official explorer/bridge views leading to loss-inducing actions
- Subdomain takeover without already-connected wallet interaction
- Open redirect
- Minor correctness issues with no meaningful economic/security impact (non-impactful correctness issues)
