# (async, static) makePlaceAlgoTxns(order, optInopt) → {Promise.<Transactions>}

🏭 makePlaceAlgoTxns(order)

Transaction Factory for Placing Buy Orders

Place a buy order into the Algodex Orderbook. This is referred to as a Maker order which is "Placed into the Orderbook". If the order has been previously placed it will have a contract key called "creator". This key determines if the order should call the ALGO delegate contract application opt in.

Once the initial transaction has been created and the contract.creator has been sent, the sdk reverts to regular payment transactions to the escrow account. These payment transactions should include a note that relates to the operation for indexing since they will not have the orderbook application call.

The transaction generator also supports bypassing the opt-in check by passing in the optIn flag
