Historical prices through the blockchain
Budget: $750 – $1,500 USD
We are looking for an experienced Blockchain developer to deliver on this introductory, short-term project with well-defined scope. If successful, additional work will follow.
Scope:
Polygon chain only
Input:
Coin ticker (e.g. POLYDOGE)
Hash of a blockchain transaction involving the coin (e.g. 0x03084b9a82b34d7b815931fd200ff950b65189e9748efde42808cd1939ef8678)
Output:
Historical price of the coin in USD (or any other stablecoin) as of the timestamp of this transaction (e.g. Oct-12-2021 01:11:45 PM +UTC)
To confirm you have read this, please explain how you would check whether the output (historical price) is correct.
Example:
In this transaction, the user deposited ~39,720,697,990.78 POLYDOGE into a liquidity pool on Apeswap. What was the value of this deposit in USD as of the timestamp of the transaction, Oct-12-2021 01:11:45 PM +UTC? https://polygonscan.com/tx/0x03084b9a82b34d7b815931fd200ff950b65189e9748efde42808cd1939ef8678
Constraint:
Do not use 3rd party price APIs such as Coinmarketcap or Coingecko.
Use only the blockchain (AMMs and DEXes)
UI:
Simple web form with the inputs and output above
Technology:
Prefer code to be written in Python.
Final deliverable to include detailed installation instructions.
