Automatic Retries

All RPC read calls (account fetches, getProgramAccounts, etc.) automatically retry on transient transport errors with exponential back-off. Writes are not retried (to avoid double-sends).

Retried errors: HTTP 429/5xx, fetch failed, ECONNRESET, ETIMEDOUT, AbortError / timeouts. Non-retryable errors (account not found, invalid params, deserialization) throw immediately.

Defaults: 6 attempts, 500 ms base delay, 5 s max delay. Override per-call with the exported withRetry helper:

import { withRetry } from '@ar.io/sdk';

const result = await withRetry(() => rpc.getAccountInfo(addr).send(), {
  maxAttempts: 3,
  baseDelayMs: 1000,
});
