networks.js gives each network a nativeCurrency (ETH, SepoliaETH) and nothing read it: every screen wrote a hardcoded ETH, so on Sepolia the balance, the value and the fee all read ETH. A nativeCurrency() helper in the popup's helpers.js returns the active network's, and every native balance, value, fee, reserve, type line and history entry is labelled with it. The "ETH" that selectedToken and txInfo.token hold is the native token's id and is unchanged. The confirmation screen's not-enough-to-pay-the-fee sentence now names the coin to add, so show() sets it. Model: opus-5-5
