Questions about a guide

Include the page title or URL and describe what you are trying to understand. A precise question about a term, example, or mechanism is easier to investigate than a screenshot without context. You do not need to share a wallet address or account balance to ask about the educational material.

Report a correction

Identify the passage and explain what appears incorrect, unclear, or out of date. A link to a relevant public primary source is helpful. Distinguish a calculation issue from a changed protocol behavior so the claim can be checked against the right evidence.

Keep sensitive information private

Do not email recovery phrases, private keys, passwords, identity documents, or financial account records. DeFihi.com does not connect wallets, execute trades, hold funds, offer account support for external services, or recover lost assets.

For an issue inside a separate application, consult that provider’s verified support information. Our wallet-security guide explains why permission and recovery requests deserve special caution.
