and right on cue, while i was writing this: ruflo, 67k stars, shipped an mcp bridge that exposed 233 agent tools over http with no auth. one POST, full RCE, every key. the loaded gun wasn't even in a drawer. CVE-2026-59726.

Rain is hiring a Product Marketing Manager, Cards.

Remote · lead level

Rain builds stablecoin card infrastructure — card transactions, cross-border payments, B2B, remittances over Visa and Mastercard rails (backed by Sapphire, Galaxy, Khosla). This seat owns go-to-market for card product launches: positioning, revenue enablement, competitor tracking across the stablecoin-card space, and BD/platform training on card-issuing fundamentals.

Reports to the founding PMM. Product-marketing, not eng — but it's the story layer for real stablecoin payments.

Apply below.

last Tuesday i handed an agent a key that could read every repo we own. not because it needed them, because scoping one is annoying and i was in a hurry. that's the real story here, not the scary-AGI headlines. go scope your keys. https://t.co/o6VoXUhFEn

openai shipped a reduced-safeguard cyber tier. the real question isn't whether they should have — it's what holds once the attacker has the same model. capability went symmetric, secrecy shrank. the moat is verification and the boundary. https://t.co/VkHTW0hNJ2

your contract passed its audit. the money left anyway. in H1 2026 ~76% of stolen funds came from operational compromise — keys, signers, frontends — not smart-contract bugs (TRM Labs). 'audited' and 'safe' are different sentences. https://t.co/4MqiDP4yXe

Paxos is hiring a Product Compliance Manager.

Remote · $116k–$133k · lead level

Paxos is the regulated blockchain infra behind PayPal's PYUSD and stablecoin rails for Mastercard, Visa and PayPal. This role owns the roadmap for compliance tooling — the tech that keeps a regulated stablecoin issuer actually compliant. Cross-functional across Compliance, Product, Engineering and Data, plus AI enablement and vendor management.

Compliance-meets-product, not pure eng — but it's where regulated crypto actually lives.

a random-number function written in 2014 drained wallets across five unrelated apps in 2026. fixed upstream in 2020 — it didn't matter. your seed is only as unpredictable as the weakest rng in your dependency tree. https://t.co/TscYKgSX1M
