What is a Re-Entrancy Attack?

Computer scientists say that a procedure is re-entrant if its execution can be interrupted in the middle, initiated over (re-entered), and both runs can complete without any errors in execution. In the context of Ethereum smart contracts, re-entrancy can lead to serious vulnerabilities.

The Exploit Race

The Exploit Race

Web3 is different from “normal software” for one brutal reason: bugs turn directly into money. In 2025 alone, an estimated $3.4B was stolen through crypto exploits. That incentive creates a uniquely hostile environment where attackers systematize vulnerability search.

Engineering Smart Contract Families for Solidity

Engineering Smart Contract Families for Solidity

Decentralized applications (dApps) (e.g., DEXes) increasingly span multiple Ethereum-compatible chains, such as a number of L2s. Although these chains are intended to be compatible with the Ethereum Virtual Machine (EVM), subtle differences in opcode implementations can significantly alter smart contract behavior and security. This poses an important question: how can developers efficiently code and manage smart contracts targeting different chains?

Will EIP-7702 Affect Your Code?

Will EIP-7702 Affect Your Code?

The upcoming EVM hardfork, Pectra, amongst other changes, will implement EIP-7702, a proposal introducing a new transaction type that allows Externally Owned Accounts (EOAs) to delegate—and later undelegate—their behavior to smart contracts. While this upgrade enhances flexibility, it also disrupts long-standing security assumptions in many deployed contracts. With the risk that malicious actors may exploit these changes once Pectra is enabled, it is crucial to assess whether your codebase might be negatively impacted.
