I like, in order of preference init, start, new or create.
The reason being is that you should be able to combine the word with both individual as well as combinations of the word contract and transaction. The word contract and transaction are not needed as part of the command, but the command should make sence when in your mind or in speaking language you combine it with the words contract and transaction.
E.g.
init contract
init transaction
init transaction contract
start contract
start transaction
start transaction contract
new contract
new transaction
new transaction contract
create contract
create transaction
create transaction contract
Wiith draw it sounds a bit weird, e.g. draw transaction sounds flawed to me, but that might be my specific language background.
