tvl and apy support for sceptre liquid sflr staking pool

hitchhooker commented 2 weeks ago

this pr adds support for fetching tvl and apy data for sceptre liquid’s sflr staking pool on flare.

key points:

fetches total pooled sflr via sdk.api.abi.call
gets current flr price from price api
calculates tvl in usd (pooled sflr * flr price)
pulls staking apy from sceptre's rewards api
retry logic for api calls with exponential backoff
exposes apy function returning formatted pool data

@hitchhooker one other thing i overlooked, why is the api on ur ui lower (44.56)?

hitchhooker commented 1 week ago

oh boy, did not realize that i'm one of those midwits that end up calculating apy on apy. fixed algorithm for calculations to be correct in the API. 44.56 hardcoded value that product manager has come up with and we will deploy next week API to be used in productin frontends(pending codereview) as well. i will let you know here then.

hitchhooker commented 1 week ago

frontends fetch now apy data from the same api as in the PR https://app.sceptre.fi/flare/dashboard#stake https://flare.sceptre.fi/
