Separate a Network View Change From Moving Assets
Changing a network selection changes context. It does not move an existing balance to another chain, convert a token or demonstrate that the application supports transactions on the newly selected network.
Identify which control changed
A website can have its own network view while a browser wallet maintains an active chain separately. Record which control you used and what each screen now displays. A standards-based provider can notify applications when its chain changes, but that does not prove every interface has refreshed correctly. If a page still shows an earlier label or balance, compare both contexts before interpreting the displayed result. Do not assume the most recent dropdown controls every request.
Confirm the outcome rather than the click
The wallet-switch proposal describes a request to change the wallet’s active chain, which the wallet may accept or refuse. A click or closed dialog therefore is not sufficient evidence of a completed switch. After a legitimate change, recheck the actual chain identifier and account. Keep account selection separate: selecting another chain does not establish that the same account remains selected in every application. This verification can be done before considering any signing request.
Understand what stays on its original chain
An Ethereum balance remains recorded on Ethereum when you view Base. A token allowance remains associated with its chain and contract; switching the visible network does not revoke it. If you need an asset on a different network, that is a separate transfer or bridging question with its own risks and compatibility checks. Do not use repeated network switching as an attempted repair for missing funds. First locate the original receipt and the chain where it was included.
Apply the distinction in RunixCoin
RunixCoin exposes mainnet and testnet wallet choices, while the public Base WETH-to-USDC quote form uses a fixed mainnet request. Its wallet network selection does not turn that form into an Ethereum, Polygon or testnet swap. If you switch context during an investigation, record the quote route separately from the balance view. Execution remains unavailable in that public form. No network-switch implementation or asset movement was tested as part of this educational page.
