Applies the needed DB modification to cancel a single order.

Function to check batching of many tokens

Token prices settled by this solution, expressed using an arbitrary reference unit chosen by the solver. These values are only meaningful in relation

Computes the absolute tolerance amount from a relative factor.

Load the specified config file. Otherwise, a temporary config file will be created with reasonable values.

Verifies the run loop drains buffered updates and returns Ok when the sender drops. Event content is not asserted here: the persistence bodies are no-

Converts a `BigDecimal` amount in Ether units to wei.

Deploys onchain components with a solver and a trader, each funded with 100 ETH.

Encode the solution into a [`Settlement`], which can be used to execute the solution onchain.

Given a path and sell amount (first token of the path) estimates the buy amount (last token of the path) and the path of liquidity that yields this re

Checks cache for the given tokens one by one. If the price is already cached, it gets returned. If it's not in the cache, a new price estimation reque

Given a path and buy amount (last token of the path) estimates the sell amount (first token of the path) and the path of liquidity that yields this re

Ensure that the onchain balances changed in accordance with the [`eth_order`].

Computes and returns the executed trade amounts given sell and buy prices.

Finds an order for cancellation. Returns an error if the order cannot be found or cannot be cancelled (for example, orders using PreSign).
