Recently, I conducted two new audits with @cantinaxyz , @spearbit , and @PashovAuditGrp . Although I donāt closely follow the market and prices, I can tell that weāre in a bull run; thereās an increase in engagements, protocols are building rapidly, and the demand for security.

Highly recommended if you want to start a full web2 and Solana Audit right nowš¦š«”.
Solana Devs and Solana Protocol BDs, I have GOOD NEWS!!. After preparing a very strong team for a Solana (Rust) + TypeScript audit, the client went with someone else. It's an opportunity for you because we could start the Audit of your protocol even TODAY. Let's do this! DM me.

Merkle trees & state roots are everywhere in blockchain. But using them safely across layers isn't trivial. If you're proving state from an L2, verifying the L2 state root is crucial before using it in any Merkle proof. Hereās how that verification can be done: š. 1ļøā£ Trusted

I have uploaded 4 reports from the last 2 months on my GitHub, reflecting continuous work and full dedication. This was one of the most complex sets of protocols Iāve audited so far. Iāve noticed that the complexity of Solana projects is evolving, moving beyond the bonding curve.

The Hacker explaining the misunderstanding of his hack is the funniest thing I have ever seen.
@deadrosesxyz @0xcastle_chain plot twist yet again. "It's time to drop a really big bombshell. Sherlock didn't miss it.
