add_filter('epg_token_address_to_purchase_url','my_token_address_to_purchase_url',1);\nfunction my_token_address_to_purchase_url($token2wcproduct) {\n $url = \"https:\/\/example.com\/buy-ether\";\n $token2wcproduct['0x0000000000000000000000000000000000000001'] = $url;\n $url = \"https:\/\/example.com\/buy-token\";\n $token2wcproduct['0x0123456789012345678901234567890123456789'] = $url;\n return $token2wcproduct;\n}\n<\/code><\/pre>\n\nTesting<\/h3>\n\n
