yam-api's Issues

Fix tvl endpoint

reduce decimals after comma

https://api.yam.finance/tvl

Yam Treasury

"/treasury"

Returns

{
  "yamHouse": 200,
  "uma": 200,
  "dpi": 200,
  "weth": 200,
  ...
}

API: Migrate apr calculation from the yam data api to the yam api

Wait for end of trial period

Move all helper functions into `utils.go`

API: Add testing for `/treasury` and `/tvl` endpoints

Add testing for the endpoints with automation.

API: Update the Yam Synths assets cycle format (for example from SEP to 09)

Create mofy orderbook endpoints

Description

For the treasury there are multiple data collection points to account for, should be cached every day. Everything should be converted to USDC for its rate. See yam treasury assets to understand where is it located at, and be able to pull it to then save it into the database and serve it on the endpoints.

Endpoints

`/treasury`

Data should be fetched and saved on the database every 1 day at 01:00 AM UTC.
Should return:
- One object.

{
  timestamp: TIMESTAMP, // time last saved when the data was collected
  values: {
    assets: {
			...
      "USDC": 400000,
      "WETH": 600000,
      "UMA": 100000,
			...
    },
    total: 1100000 // total combined assets value when the data was collected
  }
}

`/treasury-history`

Data should be fetched and saved on the database every 1 day at 01:00 AM UTC.
Should return:
- Multiple objects and each is an average of 7 days data.
- Maximum objects returned are always the past 52 objects.

{
	...
	{
	  timestamp: TIMESTAMP,
	  values: {
	    assets: {
				...
	      "USDC": 0,
	      "WETH": 0,
	      "UMA": 0,
				...
	    },
	    total: 0
	  }
	},
	{
	  timestamp: TIMESTAMP,
	  values: {
	    assets: {
				...
	      "USDC": 400,
	      "WETH": 600,
	      "UMA": 100,
				...
	    },
	    total: 1100
	  }
	},
	{
	  timestamp: TIMESTAMP,
	  values: {
	    assets: {
				...
	      "USDC": 400000,
	      "WETH": 600000,
	      "UMA": 100000,
				...
	    },
	    total: 1100000
	  }
	},
	...
}

Follow the .env.example to add or use secrets if needed.

Requirements

Adding call for the specified endpoints.
Caching the data every hour using cron to the mongo database, appending the last cached data for the /treasury endpoint calls.
On your PR include examples of what the endpoints are returning.
Use your own mongo database for testing.
Documenting the code.

API: Update the TVL with the new Synths tvl

API: Add etherscan stats

API: Update projects endpoints

/degenerative to /synths

API: Update account stats to work without the need of start and end date

Yam API: Update treasury endpoint

Update current treasury endpoint:

rename yyDAI+ to yUSD
split the yUSD value into 3 entries, yUSD, USDC, USTONKSLP
yUSD should be what we have currently on the treasury 0x97990b693835da58a281636296d2bf02787dea17
USDC should be what we have currently on the multisig usdc balance 0x744D16d200175d20E6D8e5f405AEfB4EB7A962d1
USTONKSLP should be the combination of the ustonks and usdc tokens of what we have in the USTONKS SEP pool 0xb9292b40cab08e5208b863ea9c4c4927a2308eee (value should be in usdc)
index should be what we have in the timelock here
updating all the balances to return as a number and not string

Add upunks price endpoint

API: Update `/asset` endpoint link to fetch from the renamed synths sdk

issue with treasury values loading

Describe the bug:
Upon connecting to the YAM website and dashboard page, the treasury values do not load initially. When trying just now, the values loaded after a few minutes, without me having done anything.

To Reproduce:
Steps to reproduce the behavior:

Not sure if this is universally reproducible, but it has happened to me multiple times in the last 2 days. Changing wallets sometimes fixes it. Sometimes it fixes itself after a while.

Expected behavior:
Prices and charts load quickly.

API: Migrate gas median

Migration of the gas median endpoints from the data api to the api.

3 endpoints to migrate from here:

app.get('/median', mongoFunctions.getLatestMedian);
app.get('/median-history', mongoFunctions.getMedians);
app.get('/median-range', mongoFunctions.getMedianRange);

Data API: Update rewards model to the newly added one from uma

API: Add apr endpoint

Yam APRs

"/apr" # (returns the below apr objects)
"/apr/yam" # (for yam apr in specific)
"/apr/degenerative" # (for degenerative apr in specific)

Returns

"/apr"

{
  "yam": {
    "farm": 55
  },
  "degenerative": {
    "UGAS": {
      "MAR21": 40,
      "JUN21": 40
    }
  }
}

"/apr/yam"

{
  "farm": 55
}

"/apr/degenerative"

{
  "UGAS": {
    "MAR21": 40,
    "JUN21": 40
  }
}

API: Add godoc

Read about it here.

Add new endpoint related to degenerative assets.json `/degenerative/assets`

API: Change cycle to synth in db

Describe the bug:
We currently store the synth identifier as cycle. This should be changed since it is a combination of the cycle and other attributes like {name}-{cycle}{year}.

To Reproduce:
Steps to reproduce the behavior:

Go to https://api.yam.finance/synths/ustonks-0621/index
See cycle

Expected behavior:
Instead of cycle we should display the key synth.

API: Add tvl endpoint

Yam TVLs

"/tvl" # (for all the tvl)
"/tvl/yam" # (for yam tvl in specific)
"/tvl/umbrella" # (for umbrella tvl in specific)
"/tvl/degenerative" # (for degenerative tvl in specific)

Returns

"/tvl"

"/tvl/yam"

{
  "values": {
    "farm": 5356150,
  },
  "total": 5356150,
}

"/tvl/degenerative"

{
  "values": {
    "UGAS": {
      "MAR21": 0,
      "JUN21": 0,
    },
    "UVOL": {
      "JUN21": 200,
    },
  },
  "total": 200,
}

API: Add `treasury-history` for caching the assets overtime

Add treasury history endpoint + docs:

https://api.yam.finance/treasury-history

{
  timestamp: TIMESTAMP,
  values: {
    assets: {
      "DPI": 154057.42,
      "GITCOIN": 44965.41,
      "INDEX": 487165.24,
      "INDEXLP": 2837992.33,
      "SUSHI": 674591.54,
      "UMA": 177123.28,
      "USDC": 817.84,
      "USTONKSLP": 571104.94,
      "WETH": 804516.69,
      "YAMHOUSE": 1061100,
      "YUSD": 44265.85
    },
    total: 20000000
  }
}

Change APR object field for uPUNKS

Describe the bug:
The APR endpoint returns an object like so:
{"UGAS":{"JUN":6.238587054668649},"UPUNKS":{"SEP":0.20185907125184896},"USTONKS":{"JUN":42.196161533799106}}

The issue is that uPUNKS cycle is now denoted as a number (09) instead of the word (SEP).

Please change to either 9 or 09

Fix treasury endpoint

API: Add gas tx cost, /gas/:tx

Gas / Tx

Gas cost

"/gas"

{
  "slow": 134,
  "normal": 134,
  "fast": 134
}

Transaction data

"/tx/:txHash"

{
  "fees": 0.0345115,
}

API: Fix tvl endpoint

Notes:

show even expired synths of yam synths
show the synths of yam synths in a separate object synths on the same level of farm

API: Add market price (history) endpoint

API: Update endpoint

The endpoint /synths/assets should automatically load what exists in the assets.json file populating the assets data in a returned object.

Update fetch only one time per day the uma dev mining rewards object, and not each 5min

uGAS median price endpoint not current

Describe the issue of the fix request:
The uGas reference price (median) is not updating on the Yam Synths website or on the API endpoint. Both https://data.yam.finance/median and https://data.yam.finance/median-history show an old timestamp and price (2021.10.06).

Screenshots:

API: Cache tvl values every n time, replacing it everytime as we need a single value saved not multiple

API: Check uPunks price script

API: Add YAM avg price

Description

We need to add a primary call to the coingecko api with a fallback to a secondary api of public choice, to get the yam 30 days avg price.

Coingecko: https://www.coingecko.com/en/coins/yam
To calculate it, we need to save 2 values as follows:
1. 30d should be the last 1 month full number of days, value saved every day for the yam price, averaging it over the days to get the value (from 1st to last day of the month).
2. now should be the last 30 days from today, value is also saved every day (example today is the 14th of the month, we average it as well over the days from: 14th day of last month - to date, this value is more up to date and not a fixed value).

`/30avg`

{
	"30d": "2.00",
	"now": "1.63",
}

Follow the .env.example to add or use secrets if needed.

Requirements

Adding call for the specified endpoint.
Caching the data using cron to the mongo database.
Use your own mongo database for testing.
On your PR include examples of what the endpoint is returning.
Documenting the code.

API: Add aprs, tvls
