History

Mark Stacey 8ff1d05df3 Remove recipient blocklist checker (#8943 ) It seems that this blocklist checker never worked correctly. Ever since the initial commit, it was comparing the Number `1` to the `networkId`, which is a string. Additionally, even if it did throw, the transaction continued unhindered. The user could still approve it, and there was no indication shown to the user that anything went wrong. Also some of the blocklist entries were incorrectly mixed-case, and were never hit. We can remove this for now, and re-add it later on after we rewrite the transaction controller.		2020-07-08 18:34:54 -03:00

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

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
