Mark Stacey ba54a3d83b Update ESLint config to v8 (#12886 ) The ESLint config has been updated to v8. The breaking changes are: * The Prettier rule `quoteProps` has been changed from `consistent` to `as-needed`, meaning that if one key requires quoting, only that key is quoted rather than all keys. * The ESLint rule `no-shadow` has been made more strict. It now prevents globals from being shadowed as well. Most of these changes were applied with `yarn lint:fix`. Only the shadowing changes required manual fixing (shadowing variable names were either replaced with destructuring or renamed). The dependency `globalThis` was added to the list of dynamic dependencies in the build system, where it should have been already. This was causing `depcheck` to fail because the new lint rules required removing the one place where `globalThis` had been erroneously imported previously. A rule requiring a newline between multiline blocks and expressions has been disabled temporarily to make this PR smaller and to avoid introducing conflicts with other PRs.		2021-12-09 15:36:24 -03:30

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
