Transactions

addTransaction(options)

Get some or all transactions on the network. options has the following structure:

{
  // data requests
  where?: {
    feePayer?: string[]
  }

  // related data retrieval
  include?: {
    instructions?: boolean
    logs?: boolean
  }

  range?: {
    from: number
    to?: number
  }
}

Data requests:

• feePayer sets the addresses of the fee payers. Leave it undefined to subscribe to all transactions.

Enabling the instructions and/or logs flags will cause the processor to retrieve instructions and logs that occured as a result of each selected transaction. The data will be added to the appropriate iterables within the block data. You can also call augmentBlock() from @subsquid/solana-objects on the block data to populate the convenience reference fields like transaction.logs.

Note that transactions can also be requested by the other SolanaDataSource methods as related data.

Selection of the exact fields to be retrieved for each transaction and the optional related data items is done with the setFields() method documented on the Field selection page.
