Why this matters
Protocols with leverage and pooled liquidity face unique attack surfaces:
• First-depositor & rounding attacks
• Oracle manipulation scenarios
• Pool insolvency under extreme conditions
• Gov & fee control risks

We are proud of your trust!

[AlphaDEX @alphadexapp]

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.
