Morpho · Reads onchain state
Reads a Morpho Blue market's current borrow rate as a per-second rate and an APY. The interest rate model's borrowRateView is evaluated on the market's live state at 18 decimals, and the action compounds it over a year into borrowApy. Reach for it to compare markets before borrowing, to gate a borrow on a maximum rate, or to weigh the cost against what borrowed funds will earn elsewhere.
Morpho: Find Borrow Rate Delta
1·Take
First, the plug declares a parameter named current_market, whose value the caller supplies when running it.
2·Take
Next, a second parameter named target_market is declared, again filled in by the caller at execution.
3·Get borrow rate
Reading the current_market value from slot 0.0, this step fetches that Morpho Blue market's borrow rate as a per-second rate and an APY.
4·Use
A nested plug, Morpho: Get Borrow APR, is composed here to convert the current market's borrow rate into an APR.
5·Set
The APR produced by that composed plug, drawn from slot 3.0, is stored in the variable current_apr for later comparison.
6·Get borrow rate
Turning to the target_market value in slot 1.0, this step reads that market's borrow rate the same way, per-second and APY.
7·Use
The Get Borrow APR plug runs again, this time turning the target market's borrow rate into an APR.
8·Set
That result from slot 6.0 is assigned to target_apr, giving the second value to compare.
9·Use
With both APRs in hand, the Find Value Delta plug is composed to measure the difference between current_apr and target_apr.
10·Set
From slot 8.0, the delta plug's judgment of whether the current APR is higher is saved into current_apr_is_higher.
11·Set
Slot 8.1 carries the size of the difference, which is stored in apr_delta.
12·Bubble
The current_apr_is_higher flag, wired from slot 9.0, is surfaced as an output of the plug.
13·Bubble
Finally, apr_delta from slot 10.0 is bubbled up as the plug's second output.
