End-to-end flow

Go here for the README with all components. (It currently happens to be in pdr-trueval repo).

Intro

The rest of this README is for running the "trueval" aspect.

Flow

• reads from subgraph list of template3 contracts, this gets list of all template3 deployed contracts
• for every contract, monitors when epoch is changing
• once an epoch is ended, calculate the true_val and submit.

How to run

export RPC_URL=http://127.0.0.1:8545
export SUBGRAPH_URL="http://172.15.0.15:8000/subgraphs/name/oceanprotocol/ocean-subgraph"
export PRIVATE_KEY="xx"

where:

• you can also export SOURCE_FILTER, TIMEFRAME_FILTER, PAIR_FILTER *(comma-separated lists) to limit predictions based on NFT data. E.g. export PAIR_FILTER=eth-usdt,eth-btc

Install requirements if needed

pip install -r requirements.txt

Start:

python3 main.py

Additional ENV variables used to filter:

• PAIR_FILTER = if we do want to act upon only same pair, like "BTC/USDT,ETH/USDT"
• TIMEFRAME_FILTER = if we do want to act upon only same timeframes, like "5m,15m"
• SOURCE_FILTER = if we do want to act upon only same sources, like "binance,kraken"
• OWNER_ADDRS = if we do want to act upon only same publishers, like "0x123,0x124"

Fork and customize

The actual true_val is fetch by calling function get_true_val is in trueval.py.

We call get_true_val with 4 args:

• topic: this is pair object
• initial_timestamp: blocktime for begining of epoch - 2
• end_timestamp: blocktime for begining of epoch -1

Function returns true_val, which gets submited to contract

You need to change the code to support more complex flows. Now, it's based on ccxt
