## HTTP Errors (sendRawTransaction)

| HTTP Status | Meaning                                            |
| ----------- | -------------------------------------------------- |
| `400`       | Invalid or empty transaction bytes, or missing tip |

## QUIC Connection Errors

| Error Code | Meaning                                      |
| ---------- | -------------------------------------------- |
| `0`        | Normal close                                 |
| `1`        | Unknown certificate — API key not recognized |
| `3`        | QUIC access not enabled on account           |
| `4`        | Account suspended or banned                  |

{% hint style="info" %}
QUIC is fire-and-forget — oversized payloads (>4096 bytes) and empty streams are silently dropped rather than returning an error. A legacy or v0 transaction over 1232 bytes is also dropped: only Transaction v1 can exceed that size.
