Obtaining prices onchain via ws
Token price parser onchain
A script needs to be written to subscribe to events with the addresses of token pools for different protocols and to obtain token prices from each transaction. The protocols should include:
Uniswap v1, v2, v3, v4
Pancakeswap v1, v2, v3, infinity
Balancer v1, v2, v3
Curve TWO, TRI, STBL
Sushiswap V1, V2, V3
I took the names from dexscreener, so there may be some inaccuracies; we can clarify if needed.
It should work on the Ethereum network. It may also be possible to add protocols and networks for an additional fee.
The list of tokens on the Ethereum network is taken from coingecko.
Prices need to be obtained as quickly as possible and without unnecessary requests.

We can create a price parser for the pairs mentioned above. If the history is related to on-chain arbitration, please write to me privately to discuss it better.

If there are many tokens, then it is necessary to do it not through events in pools, but by parsing new blocks. Additionally, separately parse the addition of new pairs by tokens. For this, a database will be needed to store the list of pairs and tokens.
I have a script with an implementation for Uniswap-like exchanges. The other protocols from the technical specifications can be added.
