The next bull run will test every protocol with real volume and real attackers. Fuzz it, formally verify the invariants that hold your funds and get it audited. Launch like you expect to be attacked, because you will be 🫡

Daml bug pattern worth knowing: a Canton app checked allocation.admin == registry but never required the registry to sign. Anyone can implement Token.Allocation. @JJS_OnChain breaks down his first Daml critical 👇 xitter.cf/JJS_OnChain/status/209…

rini is live in beta. First vault managers can now deploy modular vaults on HyperEVM, with access to Hyperliquid perps, spot, HIP-3 and HIP-4. It's a beta, open to whitelisted managers only.

Solid resource 😱 This is one of the most structured open-source prompt packs I’ve seen for bug bounty hunting! @mdp_sec broke down their entire workflow into 10+ reusable phases: → Recon & surface mapping → Authenticated access setup → Endpoint & vuln-class sweeping → Browser-based walkthrough → Critical-impact hunting → Triage, dedup & validation → Independent verification gates It’s Web2 focused, but the methodology is gold for anyone building AI-assisted security workflows. The evidence-first, phase-by-phase structure is exactly how you avoid hallucinated findings and actually produce reliable results: github.com/mdpsec/bug-bounty…

Hash-perfect decompilation of a Solana program is now a thing. @osec_io went from a 220KB .so blob to byte-identical Rust source for GoonFi V2, using agents scored on how closely each function matched the original bytecode. The bug they found once the code was readable? The AMM priced assets off its own vault balance. Donate tokens, skew the price, drain the other side. $6.1M at risk. If your program is live, assume your source is public. osec.io/blog/goonfi-decompil…

Whitehats defend every line. Blackhats only need one missed invariant. That gap is the difference between a clean launch and a 3am rekt thread Double down on security 🫡
