Ever wondered how leveraged positions work with real-world assets (RWAs) on-chain? It's trickier than you'd think, and @3f_xyz has a clever solution, called Grunt. 🧵

It's official.

Audits for Aero are underway.

Starting with a technical design audit by @chain_security.

@Circle Nanopayments is live on testnet! Agents can now send $USDC payments as small as $0.000001 with zero gas fees. ⚡️

We’ve been working closely with the team and audited the underlying Circle Gateway to help secure the rails for new agentic economy! 🛡️

@ydinkin @EyalKraft Really interesting !

[ChainSecurity @chain_security]

Inaccurate gas estimates on @ton_blockchain can lead to critical security issues. 🛡️

Today, our TON specialists share the knowledge gained from vulnerabilities uncovered during recent DeFi audits.

[ChainSecurity @chain_security]

Proud to help secure @Circle, supporting compliance w/ MiCA & GENIUS

Since ’22, we audited USDC & EURC on EVM @solana @SuiNetwork @Aptos @Starknet @ton_blockchain + crosschain protocols eg. CCTP V1/V2 & Circle Gateway

[Stable Summit 🦫 @stable_summit]

⚡ @Spittfires_ from @chain_security explained why L2 sequencer downtime is a real risk for stablecoins.

Frozen prices, sudden oracle updates, and rushed liquidations can all lead to bad debt.

[ChainSecurity @chain_security]

🚨 The $10M smart contract backdoor flagged by @VennBuild? It could’ve been caught right after deployment with DV.

DV (Deployment Validation) lets teams verify that smart contracts are deployed with the correct bytecode and configuration — preventing issues from misconfigurations to malicious code.

See our demo attached 📷

[ChainSecurity @chain_security]

Incorrect state proofs could have rekt a few large protocols - we teamed up with @CurveFinance to fix this before any harm could be done.
