What

The wallet balance line multiplied XEC by the placeholder rate { coin: 'xec', rate: 1 } that transformFiatRates adds for self-conversion, then labeled the result with the selected fiat code. 1,556,887.19 XEC therefore showed as ~1,556,887.19 USD.

The balance now uses the selected currency's XEC price (fiat per 1 XEC) from getAllFiatRate. At the current production rate that balance is about 14.24 USD. If that price is missing, the fiat line is omitted instead of showing a 1:1 figure.

The send form has a Max button. It fills the largest amount a P2PKH payment can include after the miner fee, using the same fee rules as the transaction builder. Change that would be below dust is left out, and that value is counted in the fee. The network fee for the entered amount is shown under the field.

After a successful broadcast, the balance drops immediately on the wallet page and in the header. Chronik often still returns the spent coins for a while; those snapshots are ignored until they no longer contain the spent outpoints, and then the balance syncs from the indexer. A partial send keeps the change locally until that sync.

Test

Checked the fiat conversion against a USD group whose XEC rate is 0.00002 (not 1) and against the live getAllFiatRate response, where both the USD and XEC groups report 9.14855882329e-06 USD per XEC.

Compared max, partial, and dust-change quotes with TxBuilder.sign for 1, 2, and 8 inputs. One coin of 1,556,887.19 XEC quotes a max send of 1,556,883.47 XEC and a 3.72 XEC network fee. next build typechecked. The signed-in wallet screen was not opened in a browser.
