Hello,
To be perfectly honest I am not sure what use it is to have bank details associated with custom coins, but it was a user request. Some people like the flexibility, and they hack the forms to look very different, so it might not even be bank details but something else entirely.
You can always provide a custom icon for any coin, thanks to the wallets_icon_url_XYZ filter: https://github.com/dashed-slug/wallets/blob/5.0.1/includes/json-api.php#L446
From the manual:
To override the URI for the Bitcoin icon:
`public function filter_wallets_coin_icon_url_BTC( $pattern ) {
return ‘https://upload.wikimedia.org/wikipedia/commons/thumb/4/46/Bitcoin.svg/2000px-Bitcoin.svg.png’;
}
add_filter( ‘wallets_coin_icon_url_BTC’, ‘filter_wallets_coin_icon_url_BTC’ );`
with regards
