Security

Approvals are the most common permission I grant in DeFi, and they are also the easiest place to make a lazy mistake. If I can’t explain exactly who is allowed to spend, for how much, and how I’ll revoke it, I don’t sign the approval.

Spinning up a brand-new wallet is the easiest win for controlling downside, but only if you treat it like production infra: isolate keys, minimize browser footprint, and cap spend under $1k until you prove the setup. This note covers how I stand up a fresh wallet with small, repeatable steps and what I check before the first approval.
