Typical status

502

What it means

A transport level failure talking to a chain node, a provider, or a bank. No state was changed.

Common causes

  • An RPC node timed out.
  • A provider endpoint was unreachable.

How to resolve

Retry with the same idempotency key. Because the key is required on every mutating request, retrying is always safe and cannot double charge.
