lightning-waitblockheight – Command for waiting for blocks on the blockchain


waitblockheight blockheight [timeout]


The waitblockheight RPC command waits until the blockchain has reached the specified blockheight. It will only wait up to timeout seconds (default 60).

If the blockheight is a present or past block height, then this command returns immediately.


Once the specified block height has been achieved by the blockchain, an object with the single field blockheight is returned, which is the block height at the time the command returns.

If timeout seconds is reached without the specified blockheight being reached, this command will fail.
