Wallet-Hygiene

Funding is where clean wallet setup meets real money and real mistakes. The goal is to move a small, controlled amount from a regulated on-ramp into your DeFi wallet, prove the plumbing works on testnet, and then bridge a tiny mainnet amount to an L2 without leaking your full balance. This walkthrough covers the drill I use: testnet first, then a sub-$500 mainnet deposit, then the first L2 bridge with a clear rollback plan.

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.
