Begin from the source, not a forwarded endpoint
A wallet, explorer and contract registry are different evidence surfaces. Start from the official documentation domain and follow its link to the relevant surface. Compare the destination host before using it. An advertisement or copied message can send you somewhere else.
A URL that contains a familiar word is not necessarily the expected domain. Treat shortened links and urgent “updated RPC” messages as claims to investigate, not as instructions to configure a wallet.
Check the configuration as a set
Match the chain ID, RPC and explorer for the same network. Mainnet settings and testnet settings must not be mixed. A working endpoint only shows that something answered a request; it does not by itself establish that the provider is suitable, private or aligned with your intended network.
Reading public records does not require giving a site spending permission. A verification workflow that unexpectedly asks for token approval has crossed into a different action.
Identify a token by chain and contract
Use the issuer or protocol’s current deployment source. Compare the complete address and chain rather than the ticker or logo. An explorer may contain multiple assets with similar names, including copies or unrelated contracts.
Verified source code means a relationship between published code and an onchain deployment under the explorer’s verification process. It does not establish a completed security audit, a fair market or the instrument’s legal rights.
Keep a small evidence note
Record the primary source URL, date, intended chain ID and public deployment address. If you later find a mismatch, that note helps identify whether documentation, interface or the actual request differed. It should contain no private key, recovery phrase, API credential or account login information.
For high-impact or unfamiliar actions, an unresolved mismatch is a reason to stop. Asking a stranger to “verify the wallet” by signing another transaction is not a substitute for resolving the evidence.
