Mobile device support for On-boarding and Notifications

This release adds mobile device support for:

• transaction awareness notifications (toasters)
• wallet readiness check dialogs (pre-flight)
• on-boarding (only includes check for wallet browser, correct network, sufficient funds)
• connect/enable modal for mobile wallets that have implemented privacy mode

Mobile on-boarding improvements

This release improves how Assist handles on-boarding on mobile platforms.

If mobileBlocked is false, onboard() will call window.ethereum.enable() if a modern provider so that the dapp can connect to the users wallet and get the current user state, then:

• reject with the current state if the user is not ready to transact
• resolve with the current state if the user is ready to transact

Bug fixes and more truffle contract tests

This release addresses a few bugs and adds more tests. The bug fix for promiEvents on transaction send or correct contract methods required a small API change on the return value. See documentation for details at at https://github.com/blocknative/assist/blob/master/README.md#promievent

• updated documentation on API change for promiEvent returned from contract method call
• added more truffle contract tests
• fixed transaction stall false positive (#177)
• fixed race condition with MM confirmation of transactions (#174)
• improved handling of promiEvent on transaction send (#179)
• fixed dropping of some contract methods (#181)
• improved determination of possible duplicate transaction (#183)
• improved resilience of confirmation callback in web3 1.0 (#185)

Fix truffle contract call, additional tests with genache

• Fix truffle estimateGas call (#171)
• More testing of web3 calls by adding genache into test suite (#153)

Fixed network check

Fixed a regression handling incorrect network on transactions and contracts. If a transaction or contract is initiated and the user's wallet is on the wrong network, Assist will show an informative dialog, but allwed the transaction/contract to proceed when the dialog is dismissed. Now the transaction/contract will not proceed. The user needs to change their wallet's network and initiate the transaction/contract again.

Fix onboard reject and network check

• updated readme to reflect how onboard resolves with the state object (#158
• onboard reject now returns state (#159)
• add network checks to call methods and show wrong network modal if user is on the wrong network (#162)

Custom notifications

This release features custom notifications a dapp can trigger at any time by calling the new notify() method. Also included is a change to the API for onboard(), which now returns the current state object instead of a string with the last onboard step. This will help dapps with their post-onboard logic. Finally, Assist styling can be updated after initialization with the new updateStyle() method.

• API change for onboard() return value.
• custom notifications via notify() API. See docs at https://github.com/blocknative/assist/blob/master/README.md#notifytype-message-options
• new updateStyle() API to change style settings after Assist is initialized. See docs at https://github.com/blocknative/assist/blob/master/README.md#updatestylestyle
• fix for automatically scrolling to bottom of notifications container so new notifications are seen
• fix for contract delegation for web3 >1.0.0-beta.37
• added more tests for contract decoration

Opera wallet fix

This release fixes a conflict with Opera browser's built-in wallet. The web3 object created by this wallet is different and not currently supported. Assist gets out of the way when the Opera wallet is in use.
