getMaxShredInsertSlot

getMaxShredInsertSlot is a Solana JSON-RPC method that returns the highest slot a node has inserted shreds for — the stage where the node writes received block fragments into its blockstore on the chain that secures SOL. The result is a single u64 slot number. Read alongside getMaxRetransmitSlot, it shows how current the data this node has actually stored is. 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

• Measure how recent the block data this Solana node has actually inserted into its blockstore is.
• Compare the value against getMaxRetransmitSlot to spot pipeline lag — a wide gap between received and inserted slots points to a node struggling to keep up.

Errors & troubleshooting

Common pitfalls

• This is a node-internal pipeline metric; do not treat it as a confirmed or finalized cluster slot. Use getSlot with a commitment level when you need to know whether a SOL transaction has actually settled.
