Transaction Controller

Transaction Controller is an aggregate of sub-controllers and trackers exposed to the MetaMask controller.

txStateManager responsible for the state of a transaction and storing the transaction
pendingTxTracker watching blocks for transactions to be include and emitting confirmed events
txGasUtil gas calculations and safety buffering
nonceTracker calculating nonces

Flow diagram of processing a transaction

txMeta's & txParams

A txMeta is the "meta" object it has all the random bits of info we need about a transaction on it. txParams are sacred every thing on txParams gets signed so it must be a valid key and be hex prefixed except for the network number. Extra stuff must go on the txMeta!

Here is a txMeta too look at:

txMeta = {
  "id": 2828415030114568, // unique id for this txMeta used for look ups
  "time": 1524094064821, // time of creation
