arcium-anchor

A helper crate for integrating Arcium into Solana programs. Provides utilities, traits, and account types that simplify the development of Anchor-based Solana programs that interact with the Arcium network for encrypted computations.

Usage

use arcium_anchor::{
    queue_computation, finalize_computation, init_comp_def,
    SignedComputationOutputs, SharedEncryptedStruct, MXEEncryptedStruct,
    traits::{QueueCompAccs, FinalizeCompAccs, InitCompDefAccs},
    prelude::*,
};

// Initialize a computation definition
init_comp_def(&ctx.accounts, circuit_source_override, finalize_authority)?;

// Queue a computation for execution
queue_computation(&ctx.accounts, inputs)?;

// Handle computation results
match computation_output {
    SignedComputationOutputs::Success(data) => {
        // Process successful computation
    },
    SignedComputationOutputs::Failure => {
        // Handle computation failure
    },
}

Main Exports

Core Functions
