one_delta.utils

Documentation for eth_defi.one_delta.utils Python module.

1delta helper functions.

Functions

`encode_path`(*, path, fees, operation, ...[, ...])	Encode the routing path and other info for 1delta flash swap.
`encode_quoter_path`(*, path, fees, exchanges)	Encode the routing path and other info for 1delta quoter.

encode_path(*, path, fees, operation, exchanges, interest_mode, trade_type=TradeType.EXACT_INPUT)

Encode the routing path and other info for 1delta flash swap.

Note: we don’t yet support all 1delta operations to keep this function simple.

Parameters

path (list[eth_typing.evm.HexAddress]) – List of token addresses how to route the trade
fees (list) – List of trading fees of the pools in the route
operation (eth_defi.one_delta.constants.TradeOperation) – Trade operation, e.g: open, trim, close
exchanges (list[eth_defi.one_delta.constants.Exchange]) – List of exchanges to use for each hop
interest_mode (eth_defi.aave_v3.constants.AaveV3InterestRateMode) – Aave v3 interest rate mode to use
trade_type (eth_defi.one_delta.constants.TradeType) – Trade type, e.g: exact input, exact output

Returns

Encoded bytes to be used with 1delta flash aggregator

Return type
