We recently completed an audit for @dHedgeOrg's Hyperliquid integration, to enable spot/perp trading (including HIP-3 perps) via a tokenized vault on HyperEVM.

The audit report will be published soon, we uncovered many interesting Hyperliquid-specific issues.

I wish to thank the Obsidian team for completing the first audit of our v2 codebase last month!

@0xSpearmint and @0xjuaan are incredibly talented, I would recommend them to any team looking for a first class audit for their smart contracts.

Our audit report for @Panoptic_xyz's v2 upgrade has been published!

Check it out below ⬇️

[Obsidian | DeFi Security @ObsidianAudits]

We placed #1/126 in the audit contest for @3janexyz.

3Jane enables unsecured lines of credit, backed by proof of crypto/bank assets, future cashflows, and credit scores.

It was a pleasure to dive into their unique architecture, and help secure their v1.1 upgrade 🫡

[Obsidian | DeFi Security @ObsidianAudits]

We're excited to be conducting an audit for @Panoptic_xyz, a permissionless options trading protocol built on Uniswap v3 & v4.

We'll be reviewing the smart contracts for their upcoming v2 upgrade.

[juan.hl @0xjuaan]

We placed #1 in the public goods track of the Hyperliquid community hackathon 🎉

Recently found out- some of the most cracked teams building on HyperEVM are already using hyper-evm-lib in their contracts.

Check out all the other great submissions below:

[juan.hl @0xjuaan]

We’ve shipped a juicy new feature to hyper-evm-lib:

Local foundry testing for all HyperEVM<>Core interactions.

You can now run fork tests for HyperEVM contracts that use CoreWriter actions, precompiles, and token bridging.
