LendingProxySimulationResponse

Proxy-mode lending response enriched with post-trade simulation. Returned on POST (with body) or GET with simulate=true. The calldata is NOT in data: send actions.transactions (in order) after mining actions.permissions. data carries only informational fields.

rateImpact object[]nullable

Projected interest-rate impact per market. Single-market actions produce 1 entry; loop actions produce 2. Null if IRM data is unavailable.

  • Array [
    • marketUidstringrequired

    Market identifier (format: lender:chainId:address)

    Example: AAVE_V3:8453:0x4200000000000000000000000000000000000006
    utilization objectrequired

    Utilization ratio (0–1)

    currentnumberrequired

    Current value

    projectednumberrequired

    Projected value after the action

    borrowRate objectrequired

    Borrow APR (%)

    currentnumberrequired

    Current value

    projectednumberrequired

    Projected value after the action

    depositRate objectrequired

    Deposit/supply APR (%) paid by the POOL. On a market whose return is the asset itself (an LST, an RWA share such as nOPAL on Morpho Blue) this is 0 — read effectiveDepositRate.

    currentnumberrequired

    Current value

    projectednumberrequired

    Projected value after the action

    intrinsicYieldnumber

    The asset's own yield in percent (LST staking yield, RWA NAV growth, a Gearbox quota rate as a negative), size-invariant, ADDED to both sides: earned on a deposit, forgone on a borrow. Absent when the lender meta was not readable when the response was built — never defaulted to 0 in that case.

    Example: 10.37
    depositRewardAprnumber

    Sum of reward-stream APRs (%) on the deposit side. Absent with intrinsicYield.

    borrowRewardAprnumber

    Sum of reward-stream APRs (%) rebated on the borrow side. Absent with intrinsicYield.

    effectiveDepositRate object

    depositRate + intrinsicYield (%), rewards EXCLUDED — what a deposit on this market actually earns, and the figure the pair book publishes as the effective supply APR. Absent with intrinsicYield.

    currentnumberrequired

    Current value

    projectednumberrequired

    Projected value after the action

    effectiveBorrowRate object

    borrowRate + intrinsicYield (%), rewards EXCLUDED — what a borrow on this market actually costs. Absent with intrinsicYield.

    currentnumberrequired

    Current value

    projectednumberrequired

    Projected value after the action

    flatboolean

    True when the market has no utilization curve to shift (Morpho Blue collateral, a fixed-rate broker): current === projected, taken from the published rates, and utilization is NaN. Present so the leg is not silently missing from a position preview.

  • ]
    • simulation objectnullable

    Projected post-trade metrics for the operator's account, or null if simulation failed. With a custom receiver this does NOT show the receiver's position.

    collateralAllActivenumber

    Collateral if all assets were enabled

    Example: 10000.5
    borrowDiscountedCollateralnumber

    Collateral discounted by borrow factors

    Example: 8000
    borrowDiscountedCollateralAllActivenumber

    Discounted collateral if all enabled

    Example: 9000
    navnumber

    Net asset value (deposits - debt)

    Example: 5000.25
    deposits24hnumber

    Deposits 24h ago (for change calculation)

    Example: 9800
    debt24hnumber

    Debt 24h ago

    Example: 4900
    nav24hnumber

    NAV 24h ago

    Example: 4900
    rewards object[]nullable

    Pending reward token claims. Each entry represents a single reward program.

  • Array [
    • assetstring
