dlmm-substream

a substreams package for indexing LP-related data emitted by meteora DLMM program. the primary focus of the substreams package is to provide a straightforward method for indexing data emitted by anchor events, in conjunction with the input accounts of the parent instruction.

outputType v/s instructionType

{
  "outputType": "...",
  "instructionType": "...",
  "args": {
    "...": {}
  }
}

apart from the basic fields such as txId, blockTime, blockSlot, the package returns outputType and instructionType. as previously mentioned, the package majorily tries to get the data from anchor events but input accounts is extracted from the parent/corresponding sibling instruction.

meteora dlmm program went through multiple iterations and there are many instructions which serve the same purpose (on a high level overview), uses the same event, but might have different ordering in input accounts. so to avoid such issues, the package goes through each type of instruction type and extract the required input accounts properly.

instructionType is the name of the parent instruction and outputType is used to indicate from where the data was extracted from i.e. from instruction arguments or anchor events (more about it below).

supported output type

• IxnAddLiquidityByStrat — extracts data and inputs accounts from add liquidity by strategy related instructions (i.e. AddLiquidityByStrategyOneSide, AddLiquidityByStrategy, AddLiquidityByStrategy2). specifically used to extract deposity strategy details.
• IxnInitializePosition — extracts data and input accounts from initialize position instruction. specifically used to extract lower bin id + width, which are not returned in AddLiquidity anchor event.
