While most of the system contracts' functions are relatively harmless, accessing some with calldata only may break the invariants of...

[Medium - 1] Ecrecover precompile doesn't behave the same as the one from Ethereum

Lines of code Vulnerability details Impact According to the Ethereum yellow paper and in the specifications of the ecrecover precompile, it is stated that if the ecrecover doesn't return anything denoted by ∅, then the return should be 0 as well. If we take a look at the current ecrecover...

L2EthToken.sol balance[address(this)] COULD UNDERFLOW

Lines of code Vulnerability details Impact The ethereum balance of the L2EthToken.sol contract can underflow thus breaking the accounting of the protocol for L2-L1 fund transfers. Proof of Concept L2EthToken.sol contract has the withdraw function to transfer funds to L1 for withdrawal. In the...

User may lose ETH

Lines of code Vulnerability details Impact User may lose ETH Proof of Concept If a non-existent function is called , the protocol may enter MsgValueSimulator.fallback.Inside the fallback function ,the protocol will transfer ETH from one address to another. If user calls a function that doesn't...
