Verify an address through two channels

Independent confirmation can catch a changed or impersonated destination.

LET’S PICTURE IT

If a delivery address changes unexpectedly, checking it through a known phone contact gives a different evidence path from replying to the suspicious message.

An address is public receiving information. It is not the private key that authorizes actions.

Animated local teaching model. No wallet, RPC or live blockchain data. Some labels and hashes are abbreviated for readability.

Look for independence

Two messages copied from the same compromised account are not necessarily independent confirmation. A previously established contact route can help verify an unexpected address change without relying only on the new request.

Confirm the full context

Ask about the network, asset and complete destination address. A correct street number in the wrong city is still a bad delivery instruction. Abbreviated prefixes are useful navigation aids, not complete identity checks.

Formatting supports a narrower claim

A checksum can help catch a typing error but cannot validate a recipient’s claim. Treat a valid format as one small check inside the larger confirmation process.

Keep the last review in the wallet

After copying or scanning, compare what the wallet actually displays with the confirmed instruction. An earlier check does not protect against a later clipboard replacement or a different selected network.

QUICK CHECK · NO PRESSURE

Are two copies of the same untrusted message automatically independent evidence?
