I want to get price of tokens like CAW, SHINJA, etc on blockchain and not using uniswap subgraph api.
router_contract_obj = w3.eth.contract(
address=Web3.toChecksumAddress(IUNISWAP_V2_ROUTER),
abi=router_contract_abi
)
prices = await router_contract_obj.functions.getAmountsOut(
10 ** int(token_metadata['decimals']),
[
Web3.toChecksumAddress(token_metadata['address']),
Web3.toChecksumAddress(WETH)
]
).call()
token_eth_price = token_eth_price[1]/10**tokens_decimals["WETH"]
above code works with any major coin like WBTC, DAI, USDC, etc..
But when I try this for tokens like CAW I get 0 as its eth value. This is probably due to very low price of these tokens: e.g. from uniswap transaction page I can see for 6.07 billion CAW is swapped for 589.3763 USDC.
I tried increasing input amount in getAmountsOut function and got the non zero value but it is not correct.
router_contract_obj = w3.eth.contract(
address=Web3.toChecksumAddress(IUNISWAP_V2_ROUTER),
abi=router_contract_abi
)
prices = await router_contract_obj.functions.getAmountsOut(
1000000000 * 10 ** int(token_metadata['decimals']),
[
Web3.toChecksumAddress(token_metadata['address']),
Web3.toChecksumAddress(WETH)
]
).call()
token_eth_price = token_eth_price[1]/1000000000
token_eth_price = token_eth_price/10**tokens_decimals["WETH"]
output: token_eth_price = 8.474e-24
Am I doing something wrong or is there any other way for this?
