you can probably use zkp_u256 - Rust or ethnum - Rust which implement it as a standard library type.

  1. Hi. I am really stuck at this problem for few days. Kindly help. In a struct { balance: U256 } i want to use U256 type but isn't supported by rust. so I imported primitive_type crates and doing with that. but when i do cargo check i am receiving the below error
  the trait `Serialize` is not implemented for `primitive_types::U256`

I want to serialize the struct with U256 variable

The primitive_types crate has a serde feature flag you can enable. Although it might be worth testing how it works with u256; most serialization targets are not going to support an integer of that size.
