Quantstamp Helps Secure IDEX 2.0

Quantstamp Announcements

Quantstamp, a leading blockchain security company, has finished its audit of IDEX 2.0, a new, higher performance update to popular decentralized exchange IDEX. Security is one of the main issues holding back Decentralized Finance, so we’re happy to be helping IDEX scale to the next stage of their growth by auditing their latest platform.

Surpassing High Gas Fees

IDEX is one of the most popular Decentralized Exchanges, with over 300k users executing over $2billion in trades. By utilizing Optimistic Rollups, it aims to scale performance further. By batching transactionstransactiItons, and rolling them up into a Merkle tree, Optimistic Rollups allow IDEX to achieve strong performance in the midst of record-high gas fees

DeFi Security Challenges

Quantstamp’s audit of IDEX helps make sure users are secure in an environment where significant funds are being lost in DeFi projects. While DeFi has seen skyrocketing growth to over $6B in value locked this year, security is also a challenge. Over $25M in value has been exploited this year in the Decentralized Finance space through hacks and exploits.

Securing IDEX 2.0

Quantstamp is happy to have helped IDEX secure IDEX 2.0 through auditing the platform’s on-chain components. Four engineers audited the code from 6-08-2020 through 07-21-2020. In total, 11 issues were identified, mostly informational with 3 low risk issues. No high risk issues were found. Further information on the audit can be found in the audit report.

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

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?

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.
