ConsenSys Diligence and Socket partner for secure Socket Liquidity Layer smart contracts

While smart contract systems of today have the capability to be deployed with permissions, upgradeable proxies, and ways to add extra logic to them, the unique selling point of this technology has always been its ability to remain immutable and predictable after the initial deployment. Systems with these properties can be used reliably by integrators with strong expectations that they will continue working as expected. From a smart contract security perspective, this allows users and builders to rest easy knowing that the code they are transacting with now will not change and surprise them.

The forgotten IPFS vulnerabilities

In 2021 we privately disclosed multiple vulnerabilities in the InterPlanetary File System but never really talked about it. Let’s change that 😊!

ConsenSys Diligence Partners with StarkWare To Expand Auditing Services

Earlier this year, ConsenSys Diligence announced its partnership with StarkWare to expand its security audit capabilities for smart contracts written in Cairo and deployed on StarkWare. “We were very impressed by the team’s in-depth analysis and understanding of Cairo, overcoming the fact that this is a new language. Consensys Diligence has already contributed to the safety of StarkEx by detecting a bug that was promptly fixed.” said Uri Kolodny, Co-founder and CEO at StarkWare about the partnership.

Destroying the Indestructible

This morning, I saw a link to Dharma’s IndestructibleRegistry. The idea behind this registry is that it keeps track of contracts that cannot be destroyed. It does this by verifying the contract’s bytecode on chain. In this post, I’ll show you how I managed to trick that verification and destroy an “indestructible” contract.

Smart Contract Languages

Welcome Back! Security for the EIP Process

The security risk profile for blockchain protocols and application is quite demanding. With high incentives to play foul and potentially severe consequences for all participants. No wonder we were surprised to find out that security was not yet explicitly part of Ethereum’s core change management process. Good thing, this finally changed.

Solidity, the Young Adult

Solidity is getting bigger! We are doing a series to present you with the language’s future plans and hopefully spark a conversation on merits and use cases.
