### Added

- Add `instant` option to `addTransaction` that adds the transaction to state immediately with default values, deferring gas estimation, fee calculation, and type resolution to the background ([#XXXX](https://github.com/MetaMask/core/pull/XXXX))
- Add `ready` property to `TransactionMeta` that indicates whether essential async data has been resolved for instant transactions ([#XXXX](https://github.com/MetaMask/core/pull/XXXX))
- Add safety guards that prevent approving, speeding up, or cancelling transactions when `ready` is `false` ([#XXXX](https://github.com/MetaMask/core/pull/XXXX))

## [62.22.0]

### Added

- Add optional `sourceHash` field to `MetamaskPayMetadata` for tracking source chain transaction hashes when no local transaction exists ([#8133](https://github.com/MetaMask/core/pull/8133))
- Add `predictDepositAndOrder` to `TransactionType` ([#8135](https://github.com/MetaMask/core/pull/8135))
