Batch

The batch domain proposes multiple transactions as a single record. Access it via instructions.batch.*. The batch PDA is deriveBatchProposalAddress(treasury, batchId). Examples assume:

import BN from "bn.js";
import { SystemProgram } from "@solana/web3.js";
import { instructions, pda } from "@aura-protocol/sdk-ts";

const now = () => new BN(Math.floor(Date.now() / 1000));
const batchId = new BN(1);
const [batch] = pda.deriveBatchProposalAddress(treasury, batchId);

proposeBatch

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

await instructions.batch.sendProposeBatch(client, payer, {
  accounts: { payer: payer.publicKey, treasury, batch, systemProgram: SystemProgram.programId },
  args: {
    batchId,
    now: now(),
    items: [], // BatchProposalItemArgs[]
  },
});

proposeConfidentialBatch

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 systemProgram.

await instructions.batch.sendProposeConfidentialBatch(client, payer, {
  accounts: {
    payer: payer.publicKey,
    treasury,
    batch,
    amountVectorCiphertext,
    perItemLimitVectorCiphertext,
    itemViolationVectorCiphertext,
    encryptProgram,
    config,
    deposit,
    callerProgram,
    cpiAuthority,
    networkEncryptionKey,
    eventAuthority,
    systemProgram: SystemProgram.programId,
  },
  args: { batchId, now: now(), itemCount: 2 },
});

Confidential batches require the Ika Encrypt network

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