Reading collection / DeFi Field Notes
Wallet security.
Follow the permissions involved in a swap or cross-network move, not just the final balance. This collection links signing habits with the practical operations that can create ongoing authority.
For each operation, identify the account, network, asset, spender, and intended consequence. Afterward, distinguish transaction completion from the permissions that may remain. Keep recovery information out of research notes and public support messages. If a request differs from the operation you intended, stopping is a valid next step; familiarity with a logo is not evidence that a request should be approved.
