FAQ
Can you work on a live incident?
Yes. Email with URGENT in the subject, your preferred comms channel, and the critical links (dashboard/tx/contract addresses). If there’s immediate risk, priority is containment + rollback.
Do you do audits?
I’m not marketing this as a formal audit service. I can do targeted reviews, hardening, and patch work with clear scope and deliverables.
What access do you need?
Usually: repo access, a minimal reproduction, and (if needed) testnet keys or restricted production access. We can start with read-only and escalate only if required.
How do payments work?
Prepaid blocks in USD. Bank transfer or USDC (Ethereum/Arbitrum). Hours roll over for 30 days.
