Polkadot Ecosystem POLKADOT PARITY SUBXT Polkadot is a multi-chain interoperability platform designed to achieve interoperability between different blockchains. It allows various blockchain networks to communicate with each other and share information while remaining efficient and secure. Substrate is a blockchain framework for building custom blockchains. It is one of the core components of the Polkadot ecosystem because Polkadot itself is built using Substrate. Substrate provides a rich set of tools and components that enable developers to easily create blockchains for their specific needs. These blockchains can run independently, or they can choose to join the Polkadot network and become its "parachain". The subxt library enables you to submit transactions to a Substrate node through remote procedure calls. Before you use the subxt library, you can use the standalone subxt command-line interface to download the metadata for the Substrate node you want to use as the target for submitting transactions. The subxt-cli tool enables you to perform two key tasks that are critical to using the subxt library: + You can use the subxt-cli tool to download the metadata from any target Substrate node. + You can use the subxt-cli tool to generate the runtime API code from the metadata from any target Substrate node. ### Audit overview - Public code repo - https://github.com/Secure3Audit/code_Parity-subxt - How many files are in scope? - 69 - Total SLoC for these contracts? - 10973 - How many external imports are there? - 48 - Is this an upgrade to an existing system? - False - Is there a need to understand a separate part of the codebase / get context in order to audit this part of the protocol? - True - Please describe the required context - Knowledge of Polkadot and substrate. - Is this either a fork of or an alternate implementation of another project? - False ### Publicly known issue What has been reported in - https://github.com/paritytech/subxt/issues?q=is%3Aissue+is%3Aclosed+label%3Abug Exclusions â What's NOT in Scope - Static websites, until you can find a way to compromise the data on the website for all of the visitors. - Bugs which have already been submitted by another user or are already known to the Parity team or have already been publicly disclosed. - Bugs in third-party tools and services weâre using (but we would be glad to connect you with the security team of the corresponding project). - Parity Technologiesâ development team, Parity Technology employees and any other person employed or providing services in any way to the company, directly or indirectly, are not eligible for rewards.

In zkSync, computation is performed off-chain and most data is stored off-chain as well. As all transactions are proven on the Ethereum mainchain, users enjoy the same security level as in Ethereum. zkSync Era is made to look and feel like Ethereum, but with lower fees. Just like on Ethereum, smart contracts are written in Solidity/Vyper and can be called using the same clients as the other EVM-compatible chains.

Please see our definition of severity here: https://docs.secure3.io/rewards/severity-standard #### Scope - mantle-v2 - https://github.com/mantlenetworkio/mantle-v2/tree/audits - commit - https://github.com/mantlenetworkio/mantle-v2/commit/7040d029eefc7a2d5a33e03bc15d6815e4a25fd6 - op-geth - https://github.com/mantlenetworkio/op-geth/tree/audits - commit - https://github.com/mantlenetworkio/op-geth/commit/64996df634fbd58d9eea82cd4cf7bf3a782c2e03 #### Out-of-scope issues Any issues reported in the previous audit report - https://secure3.io/audit/Mantle_V2 #### What is the project's general architectural structure and system design? - https://docs-v2.mantle.xyz/intro/system-components/architecture #### What are the roles in the product and the use cases and workflow for each role? - https://docs-v2.mantle.xyz/intro/system-components/architecture The content in this link depicts the transaction processing process to better understand the functioning of each module - https://docs-v2.mantle.xyz/intro/system-components/on-chain-system - https://docs-v2.mantle.xyz/intro/system-components/off-chain-system #### Which function's or module's attack vector do you have the most concern about? Blockchain/DLT - Direct loss of funds - Permanent freezing of funds (fix requires hardfork) - Network not being able to confirm new transactions (Total network shutdown) - Transient consensus failures #### Smart Contract - Loss of user funds by permanent freezing or direct theft, other than unclaimed yield - Permanent freezing of funds - Protocol Insolvency - Temporary freezing of funds #### Which parts of the system that you want the auditors to focus on? - Bridge-related contracts on L1 & L2, especially MNT & ETH lock and mint. Security of assets locked in Bridge. - The sequencer ďźshould not be attacked or crashedďź - Modification on op-gethďźincluding gas fee collection mechanism and meta transaction protocol - Mantle DA, driving blocks from unsafe to safe, and finalized. #### What is the trust setup of the system? Should all centralized roles and components be trusted? No specific trust setup for this system. Mantle v2 will upgrade from mantle v1, which is running. All centralized roles and components can be trusted. List all the vulnerabilities that are not accepted or already known to the team. #### Known issues: - 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 our protections, then we would reward you. - The fact that our contracts are upgradable via a multisig. - The fact that fault proofs are not yet running. - A bug in 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 Optimism is not affected. - The OpenZeppelin Defender scan results at https://github.com/mantlenetworkio/mantle-v2/pull/72 Known issues for the Bedrock system: - There is an edge case in which ETH deposited to the OptimismPortal by a contract can be irrecoverably stranded: - When a deposit transaction fails to execute, the senderâs account balance is still credited with the mint value. However, if the depositâs L1 sender is a contract, the tx.origin on L2 will be aliased, and this aliased address will receive the minted on L2. In general, the contract on L1 will not be able to recover these funds. We have documented this risk and encourage users to take advantage of our CrossDomainMessenger contracts, which provide additional safety measures. - Deposit transactions can be grieffed at a cost to the attacker, by filling up the MAX_RESOURCE_LIMIT. This issue is mitigated by PR 5064, which does not completely resolve the issue but does increase the cost of a sustained grief attack. A more complete fix will require architectural changes. - There are various âfoot gunsâ in the bridge which may arise from misconfiguration of a token. To minimize complexity, our bridge design does not try to prevent all forms of developer and user error. Examples of such foot guns include: - Having both (or neither of) the local and remote tokens be OptimismMintabl - Tokens which dynamically alter the amount of a token held by an account, such as fee-on-transfer and rebasing token. - When running in non-archive mode, op-geth has difficulty executing deep reorgs. We are working on a fix. #### Is there any other information or docs the auditor should know? https://docs-v2.mantle.xyz/ Rollup & Modular Go Mar 5, 12:00 AM Start Date Mar 21, 11:59 PM End Date 16 Days Duration Rewards $170,000 Chains STAKESTONE EIGEN LAYER HELPER Finished One-stop staking protocol for connecting omnichain liquidity | Omnichain Yield-bearing ETH $STONE Below are the project websites and docs - Website: https://stakestone.io/ - Twitter: https://twitter.com/Stake_stone - Deployment chain(s): Mainnet, Manta, Arbitrum - Other tech doc links and/or files: https://docs.stakestone.io/stakestone/ Staking Solidity Feb 23, 12:00 AM Start Date Feb 29, 11:59 PM End Date 6 Days Duration Chains MITOSIS Finished Mitosis is a liquidity protocol that proposes a new, capital efficient paradigm in cross-chain interoperability fit for the modular blockchain ecosystem.
