2xSwap has been independently audited by Null Return @nullreturn_io. 35 security fixes applied. Every critical and high severity finding resolved before mainnet launch.
What this means for you:
• Your deposits are protected by battle-tested OpenZeppelin standards
• Price feeds are validated through Chainlink with built-in staleness checks
• The protocol can automatically pause itself if it detects abnormal conditions
• No admin keys exist. No one — including us — can touch your funds.
The contracts are fully immutable, open-source, and verified on Etherscan.

DeFi hacks have changed a lot in the last five years.
If you’re building today, you need to understand how attacks work now, and where they actually show up in code and tooling.
We’re hosting a livestream on modern DeFi attacks, including CPIMP attacks and GlassWorm.

Hard truth:
Security ≠ “we passed an audit”.
It’s:
• audits
• ops security
• infra hardening
• team awareness
• continuous monitoring

Web3 is growing up.
And growth always punishes negligence.
If you’re building in Web3 — security is no longer optional.
