analyse_trade_by_hash(web3, uniswap, tx_hash)[source]

Analyse details of a Uniswap trade based on a transaction id.

Analyses trade fees, etc. based on the event signatures in the transaction. Works only simp;e trades.

Currently only supports simple analysis where there is one input token and one output token.

Example:

analysis = analyse_trade(web3, uniswap_v2, tx_hash)
assert isinstance(analysis, TradeSuccess)  # Trade was successful
assert analysis.price == pytest.approx(Decimal('1744.899124998896692270848706'))  # ETC/USDC price
assert analysis.get_effective_gas_price_gwei() == 1  # What gas was paid for this price

Note

This code is still much under development and unlikely to support any advanced use cases yet.

Parameters

web3 (web3.main.Web3) – Web3 instance
uniswap (eth_defi.uniswap_v2.deployment.UniswapV2Deployment) – Uniswap deployment description
tx_hash (str) – Transaction hash as a string

Returns
