getMaxRetransmitSlot

Last updated:

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.

Parameters

This method takes no parameters.

Examples

curl https://triport.io/sol \
  -X POST -H 'Content-Type: application/json' \
  -H 'Authorization: Bearer <api-key>' \
  -d '{"id":1,"method":"getMaxRetransmitSlot","params":[],"jsonrpc":"2.0"}'
const res = await fetch("https://triport.io/sol", {
  method: "POST",
  headers: { "Content-Type": "application/json", Authorization: "Bearer <api-key>" },
  body: JSON.stringify({
  "id": 1,
  "method": "getMaxRetransmitSlot",
