Opyn uses American options, but https://github.com/MattL922/greeks is built for European options.

Unfortunately, I don't see a library for American options on NPM. Hope someone makes one soon!

• Add eslint husky hook to ensure coding style on commit.

Usecase

Vault owners can setup a bot to automatically add collateral on their behave when the ETH price drop to avoid being liquidated.

Workflow

1. User creates proxy contract (the bot)
2. Fund with some USDC (or just approve)
3. Whitelist the Action (add collateral)
4. Create the task on Gelato with the user's proxy

Potential Todos

• Implement a Gelato Action: Add collateral
• Implement a Gelato Condition: Compound Price
• A wrapper contract to do step 1 ~ 4 in 1 tx

Suggestion from Musa:
Borrow ETH, exercise against some vaults, repay the ETH and keep the diffs

Before using a defi app with real money, I like playing with it on a testnet, to ensure that the UI is robust.

The Opyn Monitor works only on mainnet currently:

The current trading page for all oTokens are the same, where users can buy or sell tokens from or to Uniswap pool. But this is not ideal for option trading.

We want to design a new UI (like Deribit) for ETH options, which is more like an order-book style exchange, and it should be compatible to 0x or the future AMM

The react hook life cycle I'm using is wrong somewhere. It's currently requesting infura in a recursive manner that would eat up all the bandwidth (100000 req/day).

For now, I'm only using GA to track total traffic to the web page. It would be good to have a more detail log of users.

Aside from the additional work, is there any reason why aren't puts and calls loaded dynamically from the OptionsFactory?

OptionsFactory can be iterated to get all contracts and all put/call attributes could be derived from those contracts.

By loading them dynamically, opynmonitor.xyz could allow people to transact with all contracts ever created on the protocol and not select few. This would make opynmonitor.xyz the same what uniswapdex.com (shows all tokens and not just whitelisted) is to uniswap.exchange

Had a couple folks asking on discord and realized that for a user who has no open vaults, the checkboxes disappear, not letting them see expired vaults:

I think it should be resolved by removing this line in the red box in MyVaults/index.tsx

I was gonna make a PR but it wouldn't let me connect my wallet to test - think it might require the blocknative project id? Was seein this:

I'm currently using Infura restful api for token balance update every 5 seconds. That's too many requests.
It would be a better approach to use websocket instead.
