An alternative to the above would be to simply add the following in your child theme’s functions.php:

add_action(
	'wp_enqueue_scripts',
	function() {

		wp_add_inline_script(
			'wallets-exchange',
			<<<JS

				jQuery('html').on(
					'wallets_ready',
					function( event, coins, nonces ) {
						wp.wallets.viewModels.walletsExchangeChart.selectedTimeframe('1d');
					}
				);
JS
		);
	}
);

The JS characters must be the first characters on the line, because they close a heredoc string.
