Multicall-Based Uniswap Price Retrieval Solution

A solution that leverages the concept of multicalls to efficiently retrieve multiple token prices from Uniswap, by reducing the number of calls to the blockchain node.

Considerations

• An ethereum mainnet fork is setup in the hardhat.config.js
• The default base token for price retrieval is set to WETH
• The uniswapV3 price oracle is used to calculate ( time weighted average price )
• The .env.example is a sample file of the node url, make a .env with the example reference and put your node url ( preferebly alchemy/infura )
• .nvmrc file is set to node version 16.14.2

Future Optimizations

• The oracle library function is used to calculate the tick. This also computes few other things which are not needed
• This can be removed and a custom function can be written to calculate the tick only

Try running some of the following commands:

npm install
npx hardhat compile
npx hardhat test

Create your own mainnet fork : npx hardhat node --fork <MAINNET_NODE_URL>
