getMaxRetransmitSlot

getMaxRetransmitSlot is a Solana JSON-RPC method that returns the highest slot a node has observed coming out of its retransmit stage — the part of the turbine pipeline that forwards block shreds to peers across the network that secures SOL. The result is a single u64 slot number. It is a low-level node-internal metric that tells you how far block data has propagated through this particular node for recent slots. Send the request as a JSON-RPC 2.0 POST with an empty positional params array to https://solana.therpc.io/YOUR_API_KEY.

Use cases

• Gauge how far the node has propagated block shreds for recent slots through the turbine retransmit stage.
• Diagnose turbine or propagation lag on a specific Solana node by watching whether this slot keeps pace with the cluster's current slot.

Errors & troubleshooting

Common pitfalls

• This is a node-internal pipeline metric, not a cluster-wide confirmed or finalized slot — do not use it to decide whether a SOL transaction has settled; use getSlot with a commitment for that.
