Batch

The batch domain proposes multiple transactions as a single record. Builders live under instructions::batch::*. The batch PDA is keyed by (treasury, batch_id). Examples assume:

use aura_sdk::{anchor_accounts as accounts, types::*, AuraClient};
use solana_sdk::signature::{Keypair, Signer};

let client = AuraClient::devnet();
let now = chrono::Utc::now().timestamp();
let sys = solana_sdk::system_program::ID;

propose_batch

Proposes a public batch of transactions. Accounts: payer (s, w), treasury, batch (w), system_program.

let sig = client.propose_batch(
    &payer,
    accounts::ProposeBatch { payer: payer.pubkey(), treasury, batch, system_program: sys },
    ProposeBatchArgs {
        batch_id: 1,
        now,
        items: vec![], // Vec<BatchProposalItemArgs>
    },
)?;

propose_confidential_batch

Proposes a batch evaluated against FHE ciphertexts. Accounts: payer (s, w), treasury, batch (w), the amount/limit/violation vector ciphertexts, the Encrypt CPI accounts, and system_program.

let sig = client.propose_confidential_batch(
    &payer,
    accounts::ProposeConfidentialBatch {
        payer: payer.pubkey(),
        treasury,
        batch,
        amount_vector_ciphertext,
        per_item_limit_vector_ciphertext,
        item_violation_vector_ciphertext,
        encrypt_program,
        config,
        deposit,
        caller_program,
        cpi_authority,
        network_encryption_key,
        event_authority,
        system_program: sys,
    },
    ProposeConfidentialBatchArgs { batch_id: 1, now, item_count: 2 },
)?;

Confidential batches require the Ika Encrypt network

propose_confidential_batch takes the Encrypt CPI accounts and vector ciphertexts — see the Confidential domain.
