getMaxRetransmitSlot

getMaxRetransmitSlot returns the highest slot seen from the retransmit stage — the point in the validator's turbine pipeline where shreds received from peers are forwarded on. It is a single slot number reflecting how far the node has progressed in propagating blocks across the cluster.

This is a low-level diagnostic metric, primarily useful for observing a node's ingest/forwarding progress rather than for application data. To track the slot a node will actually serve confirmed reads from, prefer getSlot; to see how far shred insertion has advanced, compare with getMaxShredInsertSlot.

Gotchas

• The value is node-local and reflects pipeline state, not network finality — it is not a confirmed or finalized slot and should not be used as a read floor for fetching block data.
• It advances continuously as the node receives shreds; do not cache it.

None. The params array is empty.

JavaScript (fetch)

const res = await fetch("https://api.triport.io", {
  method: "POST",
  headers: {
    "Authorization": `Bearer ${process.env.TRIPORT_API_KEY}`,
    "Content-Type": "application/json",
  },
  body: JSON.stringify({
    jsonrpc: "2.0",
    id: 1,
    method: "getMaxRetransmitSlot",
    params: [],
  }),
});


const { result } = await res.json();
console.log(`Max retransmit slot: ${result}`);

TypeScript SDK (@triport/sdk)

import { TriportClient } from "@triport/sdk";


const client = new TriportClient({ apiKey: process.env.TRIPORT_API_KEY! });


const slot: number = await client.solana.getMaxRetransmitSlot();
console.log(`Max retransmit slot: ${slot}`);

Python (triport-sdk)

import os
from triport import TriportClient


client = TriportClient(api_key=os.environ["TRIPORT_API_KEY"])


slot = client.solana.get_max_retransmit_slot()
print(f"Max retransmit slot: {slot}")

• Diagnostic, not finality: this reports turbine pipeline progress. For the slot the node serves reads from, use getSlot.
• Related metric: getMaxShredInsertSlot reports the highest slot seen after shred insertion; comparing the two shows how retransmit and insert stages are tracking relative to each other.
• Moving target: the value climbs as shreds arrive — re-query rather than caching it.
• Staging: the same request works against https://staging.api.triport.io for testing.
