The "Change Owner" form should be modified for clarity such that:

• Instead of saying "Replaced Owner Address", it should say "Replace Owner:", then a line break, then the address
• The address of the owner being replaced should not be an editable form entry. Instead it should be determined by which button the user clicks on to open the form, and should not be modifiable after that.
• The "New Owner Address" and text field should go below the "Replace Owner" entry described above

When refreshing or directly visiting a wallet, the app momentarily shows the screen that says "Sorry, you tried to open a wallet with an invalid address" message. This seems to happen because the app is establishing its connection to the browser wallet (metamask, etc..).

Instead of showing this screen, we should show some kind of loading indication instead, such as a standard spinner or something similar. The app should still show this screen when warranted, that is, when the user is really trying to visit an invalid wallet.

Rough requirements

• Must at least take an address of existing multisig instance
  • (possibly defer on "create new wallet" functionality)
• must read existing multisig state and display it. This includes owners, pending transactions, etc. (can refer to current dapp for this)
• allow user to interact with the wallet - add an owner, create & propose transaction, confirm existing transaction
• Minimal styling
• integrate hardware wallet support!

See this doc for more details

When viewing a wallet, the user should be able to view the full, non-truncated data associated with a tx they are considering signing.

To enable this, we'll make the "Data" field clickable. When the user hovers over the cell, it should give some indication of click-ability, such as an icon appearing or the content becoming underlined. When the user clicks it, a modal should open that shows the full contents.

For a given multisig instance, before the first transaction is submitted, it shows "Page 1 of 0":

It also allows advancing the past page 1:

It should say "Page 1 of 1" and it should not be possible to click next.

The add owner modal should be modified to provide some basic verification to the user input

• If the ethers isAddress method returns false, the user should see "Please enter an invalid address" error message
• If the address entered is already an owner, the user should see "This address is already an owner" error message. (Be sure to compare normalized addresses here to ensure there are no capitalization differences.

The user should not be able to click "Submit" unless these checks pass

• Show Jazzicon of the address to the right of the Destination address in the Transactions section
• Show the Jazzicon of the address to the right of the "Owner Signatures" in the Transactions section
• Show the Jazzicon of the address to the right of the "Owner Address" in the Owners section
• Show the truncated address (i.e. 0x1234...5678) in the "Owner Signatures" field in the Tranasactions section (NOT in the Owners section)
• Only show the "Sign" (or "Revoke") button if the connected wallet address is one of the Owners
• Add some padding between the address and "Sign" or "Revoke" button

• Only show the "Change requirement" button if the connected wallet address is one of the Owners
• The copy of the "Change requirement" button should instead read "Change Threshold"
• Only show the "Add new transaction" button if the connected wallet address is one of the Owners
• The copy of the "Add new transaction button should instead read "Add Transaction"
• Only show the "Add new owner" button if the connected wallet address is one of the Owners
• The copy of the "Add new owner" button should instead read "Add Owner"
• Only show the "Actions" column of the Owners table if the connected wallet address is one of the Owners

The "Change Signature Requirement" modal allows the user to enter— and attempt to submit— values that are out of bounds.

The number of signatures required is at minimum 1, and at maximum, the number of "owners" on the wallet. So if a wallet has 3 owners, the only valid inputs should be 1, 2, or 3.

• If the user enters a number below 1, they should see a message saying: "Signature requirement must be at least 1"
• If the user enters a number above the number of owner, they should see a message saying: "Cannot require more signatures than owners"
• In either of the invalid scenarios described above, the "Submit" button should be inactive ("greyed out") and unclickable
• Additionally, if the user selects the number of signatures that is already set, the "Submit" button should be inactive and unclickable, but no error message is needed (example: the wallet currently requires 2 signatures to execute, and the form currently says 2)

RPC Endpoint: https://kovan.optimism.io
Chain id: 69

here are the Kovan contract addresses, but I don't think you'll need to use any of it since you won't need any L1->L2 or L2->L1 messaging https://github.com/ethereum-optimism/regenesis/tree/fix/renameKovan2ToKovan/kovan

• Contract deployment
• Hosted frontend deployment

The "Create Multisig" form on the homepage does not do any validations, and does not show error messages well.

• Update the error/validation messages to show inside a red box with red text, the same style as on the wallet modals:

• If the number of signatures is greater than the number of proposed owners, show the message "Cannot require more signatures than owners"
• If the number of signatures being requested is less than 1, show the message "Signature requirement must be at least 1"

• If the ethers isAddress method returns false, the user should see "Please enter an invalid address" error message
• If any of the addresses in the list are duplicated, show the message "Owner addresses must be unique" error message. (Be sure to compare normalized addresses here to ensure there are no capitalization differences.

• The user should not be able to click "Deploy Multisig" until at least one owner has been proposed, the number of signatures has been populated, and all validation errors are cleared.

• Addresses displayed in the wallet should be clickable (see image below)
• Hovering over the address should give some indication of they can be clicked, such as a small icon appearing or the text becoming underlined
• Clicking the link should take the user to the appropriate Etherscan URL, based on whether the user is connected to Optimistic Ethereum (chain ID 10) vs. Optimistic Kovan (chain ID 69)
  • Chain ID 10: https://optimistic.etherscan.io/address/$ADDRESS
  • Chain ID 69: https://kovan-optimistic.etherscan.io/address/$ADDRESS

See: concerns from this article https://ronan.eth.link/blog/ethereum-gas-dangers/

• Users should be able to sort the transaction table
  • The table should be sortable on the contents of the following columngs: ID, Destination, Status
  • Clicking the header of a sortable column should 1) Make it the sorted column if not already selected 2) Toggle sorting of the column from ascending to descending or vice versa if already selected
  • There should be some indicator in the header showing which column is the sorted column, and which direction, such as a small arrow pointing up or down
• Users should be able to show more than 5 records per page by selecting the number to show from a menu to the left of the page indicator. It should only show if the wallet being displayed has more than 5 transactions. The options should be as follows: 5, 7, 10, 25, 50, All

When the page exceeds the height of the browser, and the user scrolls to the bottom, the owners table runs into the bottom of the browser window. Add a little bit of padding to the bottom.

It isn't possible to change the threshold on a multisig wallet if it has only 1 owner. We should not show the "Change Threshold" button (previously "Change requirement" before #46) if the wallet has only one owner, even if that owner is the connected wallet.

• Remove Chain ID indicator
• Remove Block Number indicator
• Remove Red/Green connection indicator next to the address
• Put a grey rounded rectangle around the wallet/indicator
• Add Jazzicon to right of address
• Change copy when connected to Kovan to read "Optimistic Kovan", not "Optimistic Ethereum Testnet Kovan"
• Clicking on the network indicator should bring up the same "Connect Wallet" Modal as clicking on the wallet address does

you should be able to do a truffle config like this: https://github.com/ethereum-optimism/optimism-monorepo/blob/d117cf2e7810db5b85f1fea672c75fb74c57a249/packages/ovm-toolchain/test/config/truffle-config.js#L1-L38

and replace the import ganache from ovm-toolchain with import * as ganache from @eth-optimism/plugins/ganache see https://github.com/ethereum-optimism/plugins

we have deprecated the ovm-toolchain in favor of @eth-optimism/plugins
