These include <\/span><b>built-in types<\/b><span style=\"font-weight: 400;\"> (integers, booleans, strings), addresses used to <\/span><b>identify accounts and contracts on Ethereum<\/b><span style=\"font-weight: 400;\">, and arrays.<\/span><\/p><p><span style=\"font-weight: 400;\">Each type is optimized for <\/span><b>secure and precise transactions<\/b><span style=\"font-weight: 400;\">.
