Rust Crate Overview

The Inco Lightning SDK provides encrypted computation primitives for Solana programs built with Anchor. It enables confidential smart contracts where sensitive data remains encrypted throughout computation. Program ID: 5sjEbPiqgZrYwR31ahR6Uk9wf5awoX61YGg7jExQSwaj

​
Installation

Add to your Cargo.toml: 
[dependencies]
inco-lightning = { version = "0.1.4", features = ["cpi"] }

​
Setup

​
1. Add the program to your Anchor.toml

[programs.devnet]
inco_lightning = "5sjEbPiqgZrYwR31ahR6Uk9wf5awoX61YGg7jExQSwaj"

​
2. Import the crate in your program

use anchor_lang::prelude::*;
use inco_lightning::cpi::accounts::Operation;
use inco_lightning::cpi::{e_add, e_sub, e_ge, e_select, new_euint128};
use inco_lightning::types::{Euint128, Ebool};
use inco_lightning::ID as INCO_LIGHTNING_ID;

​
3. Add Inco Lightning program to your account struct

#[derive(Accounts)]
pub struct MyInstruction<'info> {
    #[account(mut)]
    pub authority: Signer<'info>,

    /// CHECK: Inco Lightning program for encrypted operations
    #[account(address = INCO_LIGHTNING_ID)]
    pub inco_lightning_program: AccountInfo<'info>,
}
