on GitHub

@solana/kora v0.2.0

Features

• Kit plugin architecture (#354) — New createKitKoraClient() using Kit's plugin composition pattern (planner, executor, payer plugins). Enables composability with Kit program plugins like tokenProgram(). Includes:
  • Transaction planner with Kora blockhash, fee estimation, and payment instruction injection
  • Transaction executor with sign-and-send via Kora RPC
  • Token-2022 support via tokenProgramId config option
  • Compute budget instruction support (CU limit, CU price, simulation-based estimation)
  • New peer dependencies: @solana/kit-plugin-*, @solana-program/compute-budget, @solana-program/token
  • @solana/kit peer dep bumped to ^6.1.0

Example:

import { createDefaultKoraClient } from '@solana/kora';
import { tokenProgram } from '@solana-program/token';
import { address } from '@solana/kit';

const defaultKoraClient = await createKitKoraClient({
  endpoint: 'https://kora.example.com',
  rpcUrl: 'https://api.mainnet-beta.solana.com',
  feeToken: address('EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v'),
  feePayerWallet: myWalletSigner,
});

// Compose with Kit program plugins
const client = defaultKoraClient.use(tokenProgram());

// Transfer USDC via the token plugin — Kora handles gas fees transparently
await client.token.instructions
  .transferToATA({
    authority: myWalletSigner,
    recipient: address('...'),
    mint: address('EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v'),
    amount: 1_000_000,
    decimals: 6,
  })
  .sendTransaction();

Fixes

• SignAndSendTransaction response (#353) — Add missing signature field. Return NoopSigner from getPaymentInstruction for Kit v6 signer deduplication.
• Security vulnerabilities (#348) — Patch js-yaml prototype pollution, brace-expansion ReDoS.
• ESLint v9 (#371) — Add flat config with @solana/eslint-config-solana.
