Couple of questions:

1. Protocol fee: Is the information in the link correct? 1% of TVL as an annual protocol fee. I think this is changing in v2 right?

2. Gas fee: currently we display gwei in the top corner. Is there an API we currently use for USD conversion?

1. protocol fees for v1 are not quite as simple as this Unfortunately. The annualized 1% is taken during upkeep split proportionately between long and short collateral holdings. We don't have code to calculate this and writing that code is probs not worth it imo. v2 have minting/burning fees that we know at the time of user committing so will be better then.

2. I don't believe we currently display gas fees in USD anywhere but we do have BTC/USD and ETH/USD pricing from chainlink. You might have to refactor a bit to initialize/access this pricing data since its only used in the context of BPT staking farms at the moment. Check out the way context/FarmContext/index.ts for reference. also you may already be doing this @dweberdev but I think you'll need to estimate gas spend using the ethers contract instance (poolCommitter i think)
