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, init_comp_def,
    SignedComputationOutputs, SharedEncryptedStruct, MXEEncryptedStruct,
    traits::{QueueCompAccs, CallbackCompAccs, 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,
    computation_offset,
    args,
    callback_instructions,
    num_callback_txs,
    cu_price_micro,
)?;

// Verify and deserialize computation results
let output: MyOutputType = computation_output
    .verify_output(&ctx.accounts.cluster, &ctx.accounts.computation)?;

Main Exports

Core Functions

• queue_computation() - Queue an encrypted computation for execution
• init_comp_def() - Initialize a computation definition on-chain
• comp_def_offset() - Calculate computation definition account offset

Types

• SignedComputationOutputs<O> - Enum for computation results (Success/Failure) with BLS signature verification
• SharedEncryptedStruct<const LEN: usize> - Container for shared encrypted data
• MXEEncryptedStruct<const LEN: usize> - Container for MXE encrypted data

Traits
