1·Take

Opens by declaring supply_amount, a caller parameter set at execution time to size the collateral leg.

2·Take

Declaring supply_token next, a caller parameter, names the collateral asset the flow moves.

3·Take

Taking aave_market as a caller parameter resolves every Aave action in this plug to one market.

4·Take

Following that, borrow_amount is declared, the caller-supplied figure sizing the debt leg.

5·Take

A parameter borrow_token is taken from the caller, naming the debt asset.

6·Take

Rounding out the inputs, is_winding is declared, the caller flag selecting the wind or unwind path.

7·Predicate

An if opens on the is_winding flag equalling 1, entering the wind path only when that holds.

8·Flash loan

On the wind path, a flash loan pulls the supply_amount of supply_token from the market, repaid within this transaction.

9·Set

The repayment obligation from that flash loan is saved into wind_loan_owed for the coverage check below.

10·Supply

Supplying the supply_amount of supply_token to the market mints aTokens to the socket as collateral.

11·Borrow

Against that collateral, the borrow_amount of borrow_token is borrowed from the market.

12·Get address

The Solver is held here as a named value, standing as the destination for the transfer that follows.

13·Get token balance

Reading the supply_token balance held by 0x4844...3a88 captures the holding before routing begins.

14·Transfer tokens

Sending the borrow_amount of borrow_token to the solver hands the borrowed funds over for routing.

15·Get solution

The solver takes the transferred tokens for routing, then the outcome is verified.

16·Get token balance

After routing, the supply_token balance held by 0x4844...3a88 is read again.

17·Calculate

Subtracting the pre-routing balance from the post-routing balance measures how much supply_token routing produced.

18·Compare two values

Testing that gain against wind_loan_owed returns whether it is greater than or equal to the loan owed.

19·Predicate

A require enforces that comparison equal true, aborting if the gain fails to cover wind_loan_owed.

20·End block

Closing the innermost open block ends the wind coverage check.

21·End block

Closing the next open block closes the wind branch.

22·Else branch

An else opens for the unwind path, when the is_winding flag was not 1.

23·Flash loan

On this path, a flash loan pulls the borrow_amount of borrow_token from the market, repaid within this transaction.

24·Set

The repayment obligation from that flash loan is saved into unwind_loan_owed for the coverage check below.

25·Withdraw

Withdrawing the supply_amount of supply_token from the market pulls the collateral back to the socket.

26·Get address

The Solver is held here again as a named value, the destination for the transfer that follows.

27·Get token balance

Reading the borrow_token balance held by 0x4844...3a88 captures the holding before routing begins.

28·Transfer tokens

Sending the supply_amount of supply_token to the solver hands the withdrawn collateral over for routing.

29·Get solution

The solver takes the transferred tokens for routing, then the outcome is verified.

30·Get token balance

After routing, the borrow_token balance held by 0x4844...3a88 is read again.

31·Calculate

Subtracting the pre-routing balance from the post-routing balance measures how much borrow_token routing produced.

32·Compare two values

Testing that gain against unwind_loan_owed returns whether it is greater than or equal to the loan owed.

33·Predicate

A require enforces that comparison equal true, aborting if the gain fails to cover unwind_loan_owed.

34·End block

Closing the innermost open block ends the unwind coverage check.

35·End block

Closing the next open block closes the unwind branch.

36·End block

Closing the remaining open block completes the composed transaction.
