Investigate an Address That Changes After Copy and Paste
A successful copy notification does not establish what will appear in the destination field. Check the address after pasting, especially when another application or wallet will use it for a financial action.
Locate the point of disagreement
MetaMask describes clipboard malware that replaces a copied cryptocurrency address. To investigate a suspected change without transacting, compare three values: the trusted source, the pasted text and any final wallet review. Show full strings where possible. If the source itself was already wrong, that is a different problem from substitution during copying. Record which transition changed the value rather than assuming the website, clipboard or wallet is responsible.
Do not repair the symptom by guessing
If the pasted value differs, stop the intended transfer. Repeatedly copying until one attempt looks right does not explain the mismatch. Manually editing only a few characters is also unsafe when you lack a trusted complete reference. Obtain the recipient address again through an independently verified channel. A different QR or copy mechanism still needs a final comparison; changing input methods is not evidence that a compromised device became trustworthy.
Keep diagnosis free of secrets
A read-only comparison of public addresses is enough for this question. There is no need to paste a recovery phrase into a test page or share a wallet export with someone offering help. Keep screenshots narrow and exclude unrelated clipboard contents. If unexplained substitution persists, pause financial use of that device and seek trusted device-security assistance. This guide does not prescribe downloading a cleaner, changing permissions or disabling protective software.
Separate clipboard behavior from network identity
An address can remain identical across different EVM networks, so a correct paste does not by itself identify the chain or token. Review those separately before any future action. RunixCoin has receive-address copying and QR-related interface controls, but this article is not a browser or camera test of them. The useful result is a documented comparison of public strings and their sources, with unresolved differences left unresolved rather than hidden by another attempt.
