ConsenSys Diligence Releases 0x Protocol v2 Audit Results


Consensys diligence, a carrier that audits EDCCS (referred to as smart contracts) and Ethereum-based programs, recently published effects for its audit of model two of the 0x venture’s smart contract gadget. The document lists 25 issues and presents suggestions for improving the project.

For those surprising with 0x, it is a protocol that allows the decentralized change of tokens throughout the Ethereum Blockchain. The system is predicated on Relayers instead of exchanges to facilitate token trading. These Relayers do no longer keep assets or execute trades like a change could, as a consequence allowing participants to trade immediately with their wallets.

The Consensys auditors focused on validating the safety, resilience, and functionality of 0x’s settlement machine primarily based on its underlying specifications. Considering these factors, the audit involved identifying security-associated troubles within the contracts and their overarching device, evaluating the protocol’s architecture in line with smart settlement satisfactory practices, and reviewing the great and correctness of the supply code. The audit’s scope protected clever agreement documents and check suites, except token-associated contracts.

The audit group located that, in widespread, the protocol is observed by nicely-written, complete specification documents, consisting of diagrams that visualize the gadget; it features properly-commented code to better apprehend the motive of the builders; and it consists of a thoughtfully consistent and organized contract repository.

A number of the updates covered with version two brought side instances, ensuing in some crucial issues with the device, however these have already been addressed. Of the 25 general troubles diagnosed with the protocol, thirteen were closed, leaving 12 left to resolve.

The problems indexed by way of the auditors vary, ranging from old implementations to uncertain code feedback. But, five medium-severity issues relate to insufficient checking out. The audit group mentioned that, average, the protocol “lacks a rigorous checking out approach that guarantees comprehensive take a look at insurance.” in fact, version two most effective consists of testing for 70 to 80 percentage of a number of the system’s contracts.

Besides resolving all the recognized issues, Consensys diligence recommends that 0x improve its testing approach so that “any settlement system … used on the principle network [can] acquire a hundred% check insurance,” even though the group acknowledges that one hundred percentage insurance “isn’t always a silver bullet” for the protocol’s troubles.

Furthermore, the auditors created a model to research capability threats to the smart settlement device. The usage of this model, the crew recognized six threats, which include the opportunity of relayers being hacked and hackers publishing fake orders at the systems’ buying and selling interfaces, in addition to the ability for buyers and relayers to lose all of the ERC20 and ERC721 tokens they have authorised. Consensys diligence provided viable mitigation techniques to cope with those threats.

Like several Blockchain protocol, 0x possesses diverse benefits and disadvantages. Audits like this allow engineering teams to recognize and resolve key problems with their initiatives and to proactively address any threats to their systems. The Ethereum network in the end advantages from those reports, as they cause a stronger and knowledgeable task development manner throughout the board.


In related audit news, a blockchain protocol called bzx (that’s included with 0x) was currently audited through the unbiased ethereum auditor zk labs.
